The earthwork was performed in accordance with the project specifications and the recommendations of our founda- tion investigation report dated December 19, 1984 (LCA A-84364), and supplementary consultation letters dated September 6, and September 14, 1989 (LCA 089068.AB). In addition, our firm previously provided obser- vation and testing of compacted fill and observation of foundation excavations for the existing MAI Center; our final inspection report was dated July 17, 1987 (LCA 13-86155). The scope of our services did not include either the responsibility for job safety or the function of surveying. The grading work was done to the limits and at the locations indicated by stakes and hubs set by others. Observation and ASTM D1556 (equivalent to UBC-70-2) sand -cone field density tests were made by our technician during the progress of 089042.B Page 2 the job. The results and approximate locations of the tests are attach- ed as a part of this report. The specifications required that the fill be compacted to at least 902 of the maximum density obtainable by the ASTM Designation D1557-70 (equivalent to BBC 70-) method of compaction. An allowable bearing pressure of 2,000 pounds per square foot may be imposed on the fill under the following conditions: Exterior footings extend at least two feet below the adjacent final grade, and interior footings at least two feet below the top of the adjacent floor slab. This approval is limited to the building areas as shown on the Plot Plan. Upon completion of the soils related work for the project, our final report will be submitted, giving the locations and results of all tests and observations. The site was first stripped and cleared of existing landscaping and debris from demolition. Overexcavation of up to 4+ feet in depth and for a lateral distance of 5 feet beyond in plan was necessary. along the north and east sides of the proposed MRI Addition due to the pre- sence of fill soils that were not uniformly compacted. These fill soils were beyond the limits of the previous grading and placement of compact- ed fill as part of the original MRI Center construction. Following the required overexcavation of the MRI Addition, the resultant exposed natural soils were scarified to a depth of six inches, brought to approximately optimum moisture content, and rolled with heavy compaction equipment. The existing compacted fill soils previously observed and tested by our fir in the rest of the MRI Addition and the EIt Addition pads were scarified to a depth of twelve inches, brought to approximate- ly optimum moisture content, and also rolled with heavy compaction equipment. The required fill soils, consisting of on -site silty sand and imported sand, were then placed in loose lifts not exceeding eight inches in thickness, brought to approximately optimum moisture content, and compacted by a 950 loader and a skip loader. Noisture was added, as necessary, by spraying with a water hose. At the iodations and elevations tested by us, the fill was compacted to at least the specified degree of compaction. In providing professional gecteohnical observations and testing services associated with the development of the project, we have employed accepted engineer- ing and testing procedures and have made every reasonable effort to ascertain that the soil related work was carried out in general compli- ance with the project plans and specifications, and the City of Newport Beach Municipal Cade. Although our observation did not reveal obvious Ud'G42.B Page 3 deficiencies, we do not guarantee the contractor's work, nor de the services performed by our firm relieve the contractor of responsibility in the event of subsequently discovered defects in his work. viiiSSrflt SES$/ h&7�y H.

Vice President Facilities Design & Construction Gentlemen: Grading Permit No. 1845-88 (LCA 8-88232) Final Report - Observation and Testing of Compacted Fill Incinerator Demolition 301 Newport Boulevard Newport Beach, California SCOPE This report provides a formal tecord of our observation and testing of the compacted fill placed to grade the site for the subject Incinerator Demolition Area. The location of ':he site is shown with relat'on to adjacent buildings en the attached Plot Plans. The obser- vation work was performed during November, 1988. We previously submitted our recommendations in a consultation report dated September 28, 1988 (our Job No. C-880211). Our professional services have been performed using that degree of care and skill ordinarily exercised, under similar circumstances, by reputable geotechnical engineers practicing in this or similar local- itiec. No other warranty, expressed or implied, is made as to the professional opinions included in this report. The scope of our obser- vation services did not include the responsibility for job safety. 232 Page 2 Also, since surveying is not within the scope of services, the earthwork was done to the limits indicated by stakes and hubs ,;etby ochers. OBSERVATION AND TESTING OF COMPACTED ply€. The earthwork for the project consisted of the placement of compacted fill to grade the subject demolition area, as shown on the Plate 1-A, Plot Plan, as well as the placement of compacted soils as backfill around an underground grease interceptor tank, located at the west side of the existing cafeteria building as shown on the Plate 1-B, Plot Plan. In the demolition area the fill surface was sloped and the depth of fill varied from approximately 2 to 14 feet. Approximately 10 feet of backfill was placed in the grease interceptor area. The specifi- cations required that the fill and backfill be compacted to at least 90% of the maximum density obtainable by the ASTM Designation D1557-70 method of compaction. The soils used for the required filling and hackfilling con- sisted of on -site silty sand and imported 3/4-inch crushed rock, which was used for backfill around the tank. Compaction tests were performed on representative samples of the soils, to establish the maximum dry densities. The tests were performed in accordance with the specified method of compaction, which utilizes a 1/30-cubic-foot mold in which each of five layers of soil is compacted by 25 Mows of a ten -pound hammer falling 18 inches. The results of the compaction tests were used in establishing the degree of compaction achieved during the placing of the fill and backfill. 88232 :Page 3.. The demolition work was done a few weeks before our observation services started; old footings, sprinkler lines and trash were excavated and removed. Following the required excavation, tha resultant exposed soils were scarified to a depth of twelve inches, i.'tenght to approxi- mately optimum moisture content, and rolled with heavy compaction equipment. The required fill materials were then placed in loose lifts, brought to approximately optimum moisture content, and compacted. A 644B rubber tire loader as used to compact the fill. Moisture was added by spraying with a water hose. Areas to receive hackfill were first cleared of any construction debris and loose soils, and the required hackfill soils then placed in loose lifts, brought to approxi- mately optimum moisture content, and mechanically compacted with a manually guided impact ct pactor. To establish the degree of compaction achieved, ASTM D1556 sand -cone field density tests were made as the filling and backfi.11ing progressed. The results of the field density tests are presented in the attached Table of Test Results; the approxi- mate locations of the te__.;:, are shown on the Plot Flans. A section of perforated 4-inch PVC subdrain with class 2 permeable filter was placed next to the existing banding. The subdrain extends up to the edge of concrete driveway slab. CONCLUSIONS This final report is limited to the earthwork performed through November 23, 1988, the date of our last observation and testing of compacted soils work for the project. At the locations and elevations tested by us, fill were compacted to at least the specified degree of compaction. In providing professional. geotechnical observations and testing services associated with the development of the project, we have employed accepted engineering and testing procedures and have made every reason- able effort to ascertain that the soil related work was carried out in general compliance with the project plans and specifications, and the applicable Newport Beach Municipal requirements. Although our observa- tion did not reveal obvious deficiencies, we do not guarantee the :anti -actor's work, nor do the services performed by out firm relieve the contractor of responsibility in the event of subsequently discovered defects in his work.

REPORT OF CONSULTATION REGARDING FOUNDATION DESIGN CARDIAC SERVICES ADDITION 301 NEWPORT BOULEVARD NEWPORT BEACH, CALIFORNIA ANAHEIM, CALIFORNIA FOR HOAG MEMORIAL HOSPITAL PRESBYTERIAN O92072.AB Page 1 SCOPE This report presents the results of our geotechnical consultation performed for the proposed Cardiac Services Addition. The locations of the proposed addition and our prior nearby exploration borings are shown on Plate 1, Plot Plan. This investigation was authorized to review the field and laboratory data obtained in our prior nearby investigations, and to provide recommendations for foundation design and floor slab support for the proposed addition. More specifically, the scope of the investigation included the following objectives: To evaluate the subsurface conditions, including the soil and ground water conditions within the area of proposed construction. To recommend appropriate foundation systems along with the necessary design parameters. To provide recommendations concerning construction procedures and quality control measures relating to earthwork To provide recommendations for floor slab support. The assessment of general site environmental conditions or the presence of pollutants in the soil and ground water at the site was beyond the scope of this investigation. Our recommendations are basc on the results of our prior field explorati ns and laboratory tests and appropriate engineering analyses. The results of the field explorations and laboratory tests are presented in the attached Appendix. O,c professional serv.4 have been performed using that degree of care and skill ordiiurily exercised, under similar circumstances, by reputable geotechnical consultants O92072.AB Page 2 practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. This report has been prepared for Hoag Memorial Hospital Presbyterian and their design consultants to be used solely in the design of the proposed development. The report has not been prepared for use by other parties, and may not contain sufficient information for purposes of other parties or other uses. PRIOR STUDIES We have performed several investigations for nearby projects, within the hospital complex. We have been able to use the results of those prior investigations in this study. The logs of nearby prior borings are presented in the Appendix. The pertinent prior investigations arc as follows: Geotechnical Investigation, Proposed South Tower Addition, for Hoag Memorial Hospital Presbyterian (AE-84159). Foundation Investigation, Proposed Nursing Wing and Power Plant, for Hoag Memorial Hospital (A-69080). PROJECT DESCRIPTION The proposed Cardiac Services Addition will be located on the west side of the existing hospital building. The addition will be one story in height and will be of light frame construction. The maxis . •m column loads are estimated to be about 40 kips. The floor of the addition will match the lower floor elevi:,on of the adjacent existing hospital; some compacted fill will be required to achieve the desired floor elevation. We understand the foundations of the adjacent hospital may be about 10 to 12 feet below grade. O92072.AB Page 3 EXPLORATIONS AND TESTS FIELD INVESTIGATION The soil conditions beneath the site were explored during our previous investigations by drilling four borings. The locations of the prior borings are shown on Plate 1, Plot Plan. Details of the explorations and logs of the prior borings are presented in the Appendix. LABORATORY TESTING Laboratory tests were performed during our previous investigations on selected samples obtained from the borings to aid in the classification of the soils and to determine their engineering properties. The following tests were performed: moisture content and dry density determinations, direct shear, consolidation, and compaction. Details of the laboratory testing program and test results are presented in the Appendix. SOIL CONDITIONS Fill soils, 2 to 11 feet in thickness, were encountered in the borings. The fill consists of moderately firm silty sand, clay and silt, and contains only slight debris. Deeper and/or poorer quality fill could occur between borings. The natural soils consist primarily of medium dense to dense sand and silty sand and medium stiff silt and clay. Ground water seepage was encountered at depths of 27 to 32 feet below ground surface. Ground water levels were measured at 34 to 491/2 feet below ground surface. 092072. AB RECOMMENDATIONS Page 4 FOUNDATIONS Feasible Foundation Types Shallow and deep foundation systems have been considered for support of the proposed addition. The fill soils are not considered suitable for support of the proposed addition because of settlement considerations. If the existing fill soils are excavated and properly recompacted, the addition could be supported on spread footings in the compacted fill. Alternatively, the addition could be supported on drilled cast -in -place concrete piling extending through the fill and into the natural soils. Recommendations for grading and support of floor slabs are presented in following sections of the report. Spread Footings Bearing Value Spread footings for the addition supported in the undisturbed natural soils or properly compacted fill, compacted to at least 90%, and extending at least 2 feet below the adjacent grade or floor level may be designed to impose a net dead plus live Toad pressure of 2,500 pounds per square foot. Footings for minor structures (retaining walls less than about 5 feet in height, etc.) established in the undisturbed natural soils or properly compacted fill may be designed to impose a net dead plus live load pressure of 1,500 pounds per square foot at a depth of 11/2 feet below the adjacent grade. A one-third increase in the bearing values may be used for wind or seismic loads. The recommended bearing values are net values. The weight of concrete in spread footings O92072.AB Page 5 may be taken as 50 pounds per cubic foot and the weight of soil backfill neglected when determining the downward loads. While the actual bearing value of any required fill will depend on the material used and the compaction methods employed, the quoted bearing values will be applicable if accept- able soils are used and are compacted as recommended. The bearing value of the fill should be confirmed during the grading. Settlement The settlement of the pron aed addition, supported on spread footings in the manner recommended will be about 1/2-inch. Lateral Loads Lateral loads may be resisted by soil friction and by the passive resistance of the soils. A coefficient of friction of 0.4 may be used between footings or the floor slabs and the supporting soils. The passive resistance of the natural soils or properly compacted fill against footings may he assumed to be equal to the pressure developed by a fluid with a density of 250 pounds per cubic foot. A one-third increase in the passive value may be used for wind or seismic loads. The frictional resistance and the passive resistance of the soils may be combined without reduction in determining the total lateral resistance. Footing Observation To verify the presence of satisfactory soils at design elevations, all footing excavations should be observed by personnel of our firm. Footing excavations deeper than 5 feet should be sloped back at 1:1 (horizontal to vertical) or shored. Inspection of footing excavations may also be required by the appropriate reviewing governmental agencies. The contractor should be familiar with the inspection require- ments of the reviewing agencies. O92072.AB Page 6 All applicable requirements, including OSHA requirements, should be met. Backfill and Drainage All required footing backfill and utility trench backfill within the building areas should be mechanically compacted; flooding should not be permitted. Measures should be taken to prevent ponding of water adjacent to the proposed structures. The exterior grades should be sloped to drain away from the structure to minimize ponding of water adjacent to the foundations. Proper grade and drainage devices should be provided to direct water away from the building areas. Drilled Punta Drilled Piie Capacities The downward and upward capacities of 18-, 24-, and 30-inch-diameter piles a-e 'resented on Plate 2, Drilled Pile Capacities. Dead plus live load capacities are shown; a one-third increase may be used when considering wind or seismic loads. The capacities are based on penetration into undisturbed natural soiLs. Longer piles will be required if the fill thickness is found to be greater than 11 feet during installation. The capacities are based on the strength of the soils; the compressive and tensile strength of the pile section itself should be checked to verify the structural capacity of the piles. Piles in groups should be spaced at least 21/2 diameters on centers. If the piles are so spaced, no reduction in the downward capacities of the piles need be considered due to group action. Settlement The settlement of the proposed structure, supported on drilled piling in the manner recommended, will be about %-inch. O92072.AB Page 7 Lateral Loads Lateral loads may be resisted by the piles, by soil friction on the floor slab, and by the passive resistance of the soils. The soils adjacent to a 18-inch-diameter pile, at least 20 feet long, can resist horizontal loads imposed at the top of the pile up to 9,000 pounds. The lateral resistance of other sizes of piles may be assumed to be proportional to the diameter. In calculating the maximum bending moment in a pile, the lateral load imposed at the top of the pile may be multiplied by a moment arm of 5 feet. For design, it may be assumed that the maximum bending moment will occur near the top of the pile and that the moment will decrease to zero at a depth of 20 feet below the pile cap. The lateral capacity and reduction in the bending moment are based in part on the assumption that any required backfill adjacent to the pile caps and grade beams will be properly compacted. A coefficient of friction of 0.4 may be used between the floor slab and the supporting soils. The passive resistance of the natural soils or properly compacted fill soils against pile caps and grade beams may be assumed to be equal to the pressure developed by a fluid with a density of 250 pounds per cubic foot. A one-third increase in the quoted passive value may be used when considering wind or seismic loads. The resistance of the piles, the passive resistance of the soils against pile caps and grade beams, and the frictional resistance between the floor slab and the supporting soils may be combined without reduction in determining the total lateral resistance. If the actual lateral loads on the structure can be resisted by the piles or by the passive resistar ce, or by a combination of these elements, it is our opinion that foundation tie -beams between piles will not be necessary unless there are other reasons for including them. O92072.AB Page 8 Installation All drilled pile excavations should be observed by personnel of our firm. Longer piles will be required if the fill thickness is found to be greater than 11 feet during installation. Our prior exploration borings were drilled to depths of up to 50 feet with 18-inch- diameter bucket -type drilling equipment. Heavy caving and sloughing of the auger boring walls occurred during drilling in one boring below a depth of 32 feet from the ground surface. Precautions should be taken during the installation of the piles to reduce caving and raveli ;g. Among other precautions, the drilling speed should be reduced as necessary to minimize vibration and sloughing of the sand deposits. Piles located 5 diameters on center or closer should be drilled and filled alternately, with the concrete permitted to set at least eight hours before drilling an adjacent hole. Pile excavations should be filled with concrete as soon after drilling and inspection as possible; the holes should not be left open overnight. The concrete should be placed with special equipment so that the concrete is not allowed to fall freely more than 5 feet and to prevent concrete from striking the walls of the excavations. GRADING General After clearing the site, the existing fill soils within the proposed building area should be excavated. If the building is to be supported on piling extending into the natural soils and the slab is to be structurally supported, the existing fill may be left in place. If the slab is to be supported on grade and some potential for future settlement of the floor slab is acceptable, at least the upper two feet of fill below the existing grade could be excavated, but not less than 3 feet below the final grade. The exterior grades should be sloped to drair away from the structure to minimize ponding of water adjacent to the foundations. O92072.AB Page 9 Compaction After excavating as recommended, the exposed soils should be scarified to a depth of 6 inches and rolled with heavy compaction equipment. The upper 6 inches of exposed soils should be compacted to at least 90% of the maximum dry density obtainable by the ASTM Designation D1557-78 method of compaction. All required fill should be placed in loose lifts not more than 8 inches in thickness and compacted to at least 90%. It is recommended that the moisture content of the sands and silts at the at the time of compaction vary no more than 2% below of 2% above optimum moisture content. The moisture content of the clay soils should be brought to about 4% over optimum moisture content. Material for Fill The on -site soils, less any debris or organic matter within existing fill, may be used in compacted fills. Clay soils should not be used within 1 foot of the subgrade beneath concrete slabs on grade. Field Observation The reworking of the upper soils and the compaction of all required fill should be observed and tested by a representative of our firm. This representative should have at least the following duties: Observe the clearing and grubbing operations to assure that all unsuitable materials have been properly removed. Observe the exposed subgrade in areas to receive fill and in areas where excavation has resulted in the desired finished subgrade observe proof -rolling, and delineate areas requiring overexcavation. Perform visual observation to evaluate the suitability of on -site and import soils for fill placement; collect and submit soil samples for required or recommended laboratory testing where necessary. O92072.AB Perform field density and compaction testing to determine the percentage of compaction achieved during fill placement. • Observe and probe foundation bearing materials to confirm that suitable bearing materials are present at the design grades. • Observe the installation of drilled piles. Page 10 The governmental agencies having jurisdiction over the project should be notified prior to commencement of grading so that the necessary grading permits may be obtained and arrangements may be made for the required inspection(s). FLOOR SLAB SUPPORT If the existing fill soils are excavated and properly recompacted, the floor slab and adjacent walks and slabs may be supported on grade. If the fill is left in place and the addition is supported on piling, we recommend that the slabs be structurally supported. However, if the fill thickness is too great making the reworking of it uneconomical, and if some risk of settlement is acceptable, the upper soils may be excavated to a depth of at least 2 feet below the existing grade but not less than 3 feet below the final grade. If only the upper fill soils are excavated, there is a potential for up to 2 inches of additional settlement due to consolidation of the underlying left in place fill soils. Construction activities and exposure to the environment can cause deterioration of prepared subgrades. Therefore, we recommend that our field representative observe the condition of the final subgrade soils immediately prior to slab on grade construction and, if necessary, perform further field density and moisture content tests to determine the suitability of the final prepared subgrade. O92077.AB Page 11 Where a floor slab covering that would be critically affected by moisture, such as vinyl, is to be used, we suggest that the floor slab be supported on a 4-inch-thick layer of gravel or on an impermeable membrane as a capillary break. A suggested gradation for the gravel layer would be as follows: Sieve Size Percent Passinp 3/4" 90 - 100 No. 4 0 - 10 No.100 0-3 If the membrane is used, a low -slump concrete should be used to minimize possible curling of the slabs. The concrete slabs should be allowed to cure properly before placing vinyl or other moisture -sensitive floor covering. O92072.AB Page 12 BASIS FOP RECOMMENDATIONS The recommendations provided in this report are based on our understanding of the described project information and on our interpretation of the data collected during the subsurface exploration. We have made our recommendations based on experience with similar subsurface conditions under similar loading conditions. The recommendations apply to the specific project discussed in this report; therefore, any change in building loads, building location, or site grades should be provided to us so we may review our conclusions and recommendations and make any necessary modifications. The recommendations provided in this report are also based on the assumption that the necessary geotechnical observations and testing during construction will be performed by representatives of our firm. The field observation services are considered a continuation of the geotechnical investigation and essential to verify that the actual soil conditions are as anticipated. This also provides for the procedure whereby the client can be advised of unanticipated or changed conditions that would require modifications of our original recommendations. In addition, the presence of our representative at the site provides the client with an independent professional opinion regarding the geotechnically related construction procedures. If another firm is retained for the geotechnical observation services, our professional responsibility and liability would be impaired. -oOo- O92072.AB Page A-1 APPENDIX EXPLORATIONS The soil conditions beneath the site were explored during two previous investigations by drilling four borings at the locations shown on Plate 1. The borings were drilled to depths of 45 to 51 feet below the existing grade using 18-inch-diameter bucket -type drilling equipment. Caving of the boring walls did occur during the drilling of one boring with the bucket auger but casing or drilling mud was not used to extend the bucket borings to the depths drilled. The soils encountered were logged by our field technician, and undisturbed and loose samples were obtained for laboratory inspection and testing. The logs of the previous borings are presented on Plates A-1.1 through A-1.4; the depths at which undisturbed samples were obtained are indicated to the Left of the boring logs. The energy required to drive the sampler 12 inches is indicated on the logs. The soils are classified in accordance with the Unified Soil Classification System described on Plate A-2. LABORATORY TESTS The field moisture content and dry density of the soils encountered were determined by performing tests on the undisturbed samples. The results of the tests are shown to the left of the boring logs. Direct shear tests were performed on selected undisturbed natural samples from our two previous investigations to determine the strength of the soils. The tests were perforated at field and increased moisture contents and at various surcharge pressures. The yield -point values determined from the direct shear tests are presented on Plate A-3.1 and A-3.2, Direct Shear Test Data. O92072.AB Page A-2 Confined consolidation tests were performed on four undisturbed samples to determine the compressibility of the soils. Water was added to one undisturbed sample during the test. The results of the tests are presented on Plates A-4.1 through A-4.3, Consolidation Test Data. -oOo- 0 Y V Q 23 Q24 13Q 4 0 Q 14 JOBAE 84153 Q10 Q 12 Q9 EXI STI N G HOSPITAL Q 4 . F01 EON. EL EV S.

California The rough grading of the site consisting of the excavation performed to reach the design building elevations for the proposed Emergency Room Expansion and Renovation project is approved as of March 8, 1993. The exposed natural soils will provide support for the building foundations and floor slab, as well as subgrade support for adjacent walks and slabs. The grading was performed in accordance with the project specifications and the recommendations of our geotechnical investigation report dated November 7, 1990 (090072.AEO). The scope of our services did not include either the responsibility for job safety or the function of surveying. The grading work was done to the limits and the locations indicated by stakes and hubs set by others. The specifications require that any fill to be placed be compacted to at least 90% of the maximum dry density obtainable by the ASTM Designation D1557-78 (equivalent to UBC 70-1) method of compaction. Spread footings carried at least 1 foot into the firm undisturbed natural soils and at least 2 feet below the adjacent grade or floor level may be designed to impose a net dead plus live load pressure of 6,000 pounds per square foot. A one-third increase in the bearing value may be used for wind or seismic bads. Adjacent to the existing building, footings should extend to at least the same level as the existing footings. Footings for minor structures (auxiliary retaining walls and free-standing walls) may be designed to impose a net dead plus live load pressure of 1,500 pounds per square foot at a depth of at least 1 foot below the adjacent grade. Such footings may be established in either properly compacted fill or the natural soils. This approval is limited to the building area shown on the attached Plot Plan. Upon completion of the grading, our final report will be submitted, giving the locations and results of all tests and observations. 2631.30107.0001 Page 2 After the site was stripped and cleared, the building area was excavated up to approximately 15 feet in depth below the existing grade for the service level, and established in firm, natural soils. These natural soils are considered to be suitable for the construction of the proposed project. Temporary unsurcharged construction slopes were made at 1:1. During the rough grading, no fill soils were placed. In our opinion, the geotechnical related work was performed in the general compliance with the project plans, specifications, and the City of Newport Beach Municipal Code and is considered suitable for the intended use. The City of Newport Beach required, prior to issuing a certificate of occupancy, a statement from the geotechnical engineer that all subgrades supporting either concrete slabs -on -grade or asphaltic paving have been observed for adequacy for the intended use. To comply with this requirement it is essential that a representative of our firm observe all such subgrades so that we can confirm their proper preparation. Our firm must observe the subgrade for all concrete slabs -on -grade and for asphaltic paving, immediately prior to placement, so that our final report can provide the required documentation to the City of Newport Beach. In providing professional geotechnical observations and testing services, we have employed accepted ougineering and testing procedures, and no other warranty, expressed or implied, is made in providing this professional opinion. While we have made every reasonable effort to perform our services to at least the standard of care of our profession, and our observations did not reveal obvious deficiencies, we do not guarantee the contractor's work, nor do the services performed by our firm relieve the contractor of responsibility in the event of subsequently discovered defects in his work.

The expansion, which will be constructed adjacent to the existing emergency room, will be two stories high and will have a partial basement. No unusual geologic conditions appear to be present on or adjacent to the site that would constitute a geologic hazard to the proposed expansion. Fill soils (possibly sewer line backfill), about 5 feet in thickness, were encountered in one of the borings_ The underlying natural soils consist of dense sand and silty sand and moderately firm to firm clay and silt. The natural soils will offer adequate support to the proposed addition on spread footings. No exceptional difficulties are anticipated in excavating at the site; conventional earth - moving equipment may be used. Where the necessary space is available, temporary unsurcharged excavations may be sloped back without shoring. To provide support for slabs on grade, all fill soils and any disturbed natural soils should be excavated and replaced as properly compacted fill, and all required additional fill should be properly compacted. Slabs on grade should be underlain by a layer of relatively non -expansive soils. LCA O90072.AEO Page 2 SCOPE This report presents the results of a geotechnical investigation of the site of the subject proposed Hoag Memorial Hospital addition. The locations of the existing hospital buildings, the proposed addition, and our exploration borings are shown on Plate 1, Plot Plan. This investigation was authorized to determine the static physical characteristics of the soils beneath the proposed addition and to provide recommendations for grading, design of foundations and walls below grade, and for floor slab support. More specifically, the scope of the investigation included the following objectives: • To evaluate the existing surface and subsurface conditions, including the soil and ground water conditions, within the area of the proposed construction. • To perform geologic -seismic studies to meet the current requirements of the Office of the State Architect. • To recommend appropriate foundation systems together with the necessary design parameters. • To provide recommendations for excavation and design data for design of shoring. • To provide earth pressure parameters for basement calls. • To present recommendations relating to earthwork and grading. • To provide recommendations for floor slab support and for pavement thicknesses. In addition, corrosion studies were to be performed for us by M. J. Schiff & Associates, Consulting Corrosion Engineers. LCA O90072.AEO Page 3 The results of the field explorations and laboratory tests, which together with the previous data form the basis of our recommendations, are presented in Appendix A The results of the corrosion studies are also presented in Appendix A. Geologic and seismic supporting data arc presented in Appendix B. Our professional services have been performed using that degree of care and skill ordinarily exercised, under similar circumstances, by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. This report has been prepared for the Hoag Memorial Hospital Presbyterian and their design consultants to be used solely in the design of the proposed addition. The report has not been prepared for use by other parties, and may not contain sufficient information for purposes of other parties or other uses. STRUCTURAL CONSIDERATIONS The proposed addition, which is shown in plan on Plate 1, will be two stories high and will be constructed over an existing loading dock and service area that are to remain. There will be an enclosed service area at grade. The addition will be of steel frame and metal deck construction with light -weight concrete. Maximum column loads will be about 300 kips. The service level slab will be at Elevation 64, requiring excavation up to about 12 feet deep. Retaining walls will be constructed along the excavated areas. The loading dock will be at about Elevation 64, which is the finished floor level of the adjacent existing hospital building. The existing concrete slab within the approach to the loading dock will be demolished and replaced with a new concrete slab at about Elevation 61. LCA O90072.AEO EXPLORATIONS AND TESTS Page 4 FIELD INVESTIGATION The site was explored by drilling three borings at the approximate locations shown on Plate 1. Each of the borings was drilled to a depth of approximately 30 feet below the existing grade. Further details of the explorations and logs of the borings are presented in Appendix A. LABORATORY TESTING Laboratory tests were performed on selected samples obtained from the borings to aid in the classification of the soils and to determine their engineering properties. The following tests were performed: moisture content and dry density determinations, direct shear, consolidation, compaction, and Expansion Index. Details of the laboratory testing program and test results are presented in Appendix A. The results of corrosion studies are also presented in Appendix A. SITE CONDITIONS The proposed addition will be constructed adjacent to the northwest corner of the existing emergency room. The majority of the proposed construction area is paved with asphalt and concrete and is used as a service area. A concrete ramp and grass area exist on the north side of the site. The ground surface slopes to the south and west Underground utility lines (sewer, water, and electrical) cross the site. LCA 090072.AEO Page 5 SOIL CONDITIONS Fill soils, 51/2 feet in thickness, were encountered in one of the borings; an 8-inch-diameter clay pipe was encountered in the fill. The existing fill (possibly sewer line trench backfill), which is not uniformly well compacted, consists of sand, silt, and clay, and was found to be free of debris at the boring location. Deeper and/or poorer quality fill could occur between borings. The natural soils beneath the site consist of sand, silty sand, clay, and silt. The sand and silty sand are dense. The silt and clay soils are moderately firm to firm. The clay soils are somewhat expansive and would swell and shrink with changes in the moisture content. Water was not encountered within the 301/2-foot depth explored. Based on the corrosion studies, the results of which are presented in Appendix A, the site is classified as severely corrosive to ferrous metals. The Schiff report should be referred to for a discussion of the corrosion potential of the soils. GEOLOGY GENERAL The site is situated on Newport Mesa, about .75 mile from the Pacific Ocean at an elevation of about 60 to 76 feet above sea level (United State Geological Survey datum). Newport Mesa is one of several physiographic features that compose the Orange County Coastal Plain. The hills and mesas of the Newport area are separated by erosional gaps that were incised into the late Pleistocene land surface. Two such features are Santa Ana Gap, which is occupied by the Santa Ana River northwest of Newport Mesa, and Upper Newport Bay, which separates Newport Mesa from the San Joaquin Hills to the east. The site is near the southern end of the Los Angeles Basin, a deep, northwest -trending structural basement trough filled with a thick sequence of Quaternary sediments and Tertiary and Cretaceous sedimentary rocks. LCA O90072.AEO Page 6 The site is shown in relation to regional geologic features on Plate 2, Regional Geology. The relationship of the site property to local geologic features is shown on Plate 3, Local Geology. The site is shown in relation to major fault zones on Plate 4, Regional Seismicity. GEOLOGIC MATERIALS Fill Artificial fill materials, 535 feet in thickness, were encountered in one of our borings. The fill is composed of mottled brown mixtures of sand, silt, and clay. This depth may not reflect the overall conditions at the site, however, since we believe the boring was placed over a backfilled trench. Two other borings drilled on -site did not encounter artificial fill. Terrace Deposits All three borings encountered Pleistocene marine terrace deposits composed of interbedded grey and brown clay, silt, and sand. These deposits are typical of the poorly indurated sediments that blanket the mesas of the Orange County Coastal Plain. The terrace deposits are underlain by claystone and siltstone of the late Miocene age Monterey Formation, about 40 feet below the existing ground surface. Monterey Formation Monterey Formation rocks are exposed in the bluffs at the south and west edges of Newport Mesa. The Monterey Formation, together with other underlying Tertiary age sedimentary rocks, are estimated to be about 13,000 feet thick beneath Newport Mesa and are underlain by igneous and metamorphic basement complex rocks. GROUND WATER Significant water -bearing materials do not occur on the Newport Mesa, but perched ground water is present locally within the terrace deposits capping Newport Mesa and at the contact between the terrace deposits and the less permeable Monterey Formation. The LCA O90072.AEo Page 7 underlying bedrock is considered to be non-waterbearing. Because of the proximity of the site to the Pacific Ocean, however, the formation may be saturated at or near sea level elevation. The ground water level beneath the site occurs at about 40 feet near the terrace -bedrock contact. Water was not encountered in our exploratory borings drilled to a maximum depth of 304 feet. GEOLOGIC HAZARDe General The geologic hazards at the site are essentially limited to those caused by earthquakes. The major damage from earthquakes is the result of violent shaking from earthquake waves; damage due to actual displacement or fault movement beneath a structure is much less frequent. The violent shaking would occur not only immediately adjacent to the earthquake epicenter, but within areas for many miles in all directions. Faults The numerous faults in Southern California include active, potentially active, and inactive faults. Detailed information concerning the faults is presented in Tables B-1, B-2, and B-3 in Appendix B. No faults or fault -associated features were observed on the site during the field reconnaissance. The site is not located in a currently established Alquist-Priolo Special Studies Zone. No known faults underlie the proposed building. In our opinion, there is little probability of surface rupture due to faulting on the site. The nearest active fault is the North Branch fault of Newport -Inglewood fault zone, located 0.5 mile to the southwest. Other active faults in the region are the Whittier and San Andreas fault zones located approximately 21 miles north-northeast and 51 miles northeast of the site, respectively. lEra LCA 090072.AEO Page 8 The potentially active Pelican Hill fault is located 3.0 miles east of the site. The nearest inactive fault is the Shady Canyon located 6.7 miles north-northeast of the site. This inactive fault will not adversely impact the site. Seismicity The epicenters of earthquakes with magnitudes equal to or greater than 4.0 within a radius of 100 kilometers (62 miles) of the site are shown in Table B-4 in Appendix B. Other pertinent information regarding these earthquakes is also shown in Table B-4. The historic seismic record indicates that 296 earthquakes of Richter magnitude 4.0 and greater have occurred between 1932 and 1987 within about 100 kilometers of the site. An earthquake recurrence curve, based on the data presented in Table B-4, is included as Plate 5, Recurrence Curve. The location of the site in relation to the active Newport -Inglewood fault zone indicates that the site could be exposed to a greater than normal seismic risk than other areas of Orange County. The epicenter of the March 11, 1933 (Greenwich Civil Time) magnitude 6.3 Long Beach earthquake was located approximately 2.5 miles southwest of the site. This earthquake, although of only moderate magnitude, ranks as one of the major disasters in Southern California. The majority of the damage was suffered by structures that are now considered substandard construction and/or were located on filled or saturated ground. The epicenter of the February 9, 1971 magnitude 6.4 San Fernando earthquake was about 61 miles north-northwest of the site. Surface rupture occurred on several segments of the San Fernando fault zone. The large amount of damage caused to buildings occurred primarily because of inadequately designed or built structures. LCA O90072.AEO Page 9 The epicenter of the October 1, 1987 magnitude 5.9 Whittier Narrows earthquake was located about 32 miles north-northwest of the site. The majority of the structural damage resulting from this earthquake occurred in structures built prior to the more stringent building codes adopted after the 1971 San Fernando earthquake. A magnitude 5.3 aftershock occurred three days after the main shock along a previously unrecognized fault that may be a northem extension of the Whittier Fault. Recently, minor earthquakes, registering 5.0 and 4.6 magnitude, occurred in the Pasadena and Newport Beach areas on December 3, 1988 and April 7, 1989, respectively. These earthquakes resulted in only minor damage. The epicenter of the Pasadena earthquake was about 38 miles north-northwest of the site. The Newport Beach earthquake epicenter was located about 1 mile southeast of the site. Liquefaction Liquefaction potential has been found to be greatest where the ground water level is shallow and loose Fine sands occur within a depth of 50 feet. Liquefaction potential decreases with increasing grain size and clay and gravel content, but increases as the ground acceleration and duration of shaking increase. Ground water level is at an estimated depth of 40 feet below ground surface near the contact between the terrace deposit and the Monterey Formation siltstone. The terrace deposits and siltstone are generally dense to very dense; accordingly, the potential for liquefaction is judged to be low. Seismic Settlement and Subsidence Seismic settlement often occurs when loose to medium dense granular soils densify during ground shaking. If such settlement were uniform beneath a given structure, damage would be minimal. However, because of variations in distribution, density, and confining conditions of the soils, such settlement is generally non -uniform and can cause serious structural damage. Such seismically induced settlement can occur in both dry and partially saturated granular soils as well as in saturated granular soils. Differential settlement may also be induced by ground failures such as liquefaction, flow slides, and surface ruptures. LCA O90072.AEO Page 10 Generally, differential settlements due to such conditions would be much more severe than those due to densification alone. The site is underlain by dense Pleistocene terrace deposits; th.; probability of settlement of this material is slight. Subsidence due to the extraction of fluids is not known to have occurred at this location. Additionally, no peat was encountered in our exploratory borings; therefore, subsidence associated with peat oxidation is unlikely. Stability The site is located on the eastern bank of a northwest -trending drainage channel on the. Newport Mesa. The channel has been recently developed and is now a paved driveway; no future erosion of the drainage is anticipated. The floor of the proposed structure will be below the adjacent drainage channel elevation, and the building walls will buttress a proposed cut slope to the north and east. The cut slope will expose the relatively flat -lying terrace deposits, but not the Monterey formation siltstone. These terrace deposits are generally massive with no well-defined planes of weakness such as bedding or joints. No indications of slope instability were noted on the site. The site is not on or in the path of any known existing or potential landslides. The potential for future slope instability is judged to be low. Flooding, Tsunamis, and Seiches The site is in a "Zone X" flood hazard area as established by the Federal Insurance Administration. As defined, "Zone X" is an area of a 500-year flood or an area of a 100- year flood with average depths of less than 1 foot, or with areas less than 1 square mile and areas protected by levees from 100-year floods. As the site is located about .75 mile from the Pacific Ocean at an elevation of about 60 feet above sea level, the risk of damage from seismic sea waves (tsunamis) need not he considered. LCA O90072.AEO Page 11 The site is not located downslope of any large bodies of water that would adversely affect the site in the event of earthquake -induced failures or seiches (wave oscillations in a body of water due to earthquake shaking). CONCLUSIONS AND RECOMMENDATIONS GEOLOGIC CONSIDERATIONS Based on the geologic findings, no active or potentially active faults are known to exist on - site. Accordingly, surface rupture from faulting is considered unlikely. The site could be subjected to significant ground shaking in the event of an earthquake cn any of the nearby active or poter.tially active faults. Ground shaking hazard is common in the Southern California area and can be minimized by proper structural design and construction. The location of the site in relation to known fault. indicates that the immediate area could be exposed to greater than normal seismic risk for the Orange County Coastal Plain as a whole. The possibility of liquefaction is judged to be low, considering the dense nature of the underlying granular materials and the absence of shallow ground water in the site vicinity. No landslides are indicated on or adjacent to the site, and the potential for future slope instability is judged to be low. The site is in an area between 100- and 500-year flood boundaries. Other hazards, such as tsunamis, seiches, and subsidence, are not indicated. FOUNDATIONS General The existing fill soils are not considered suitable for foundation or floor slab support. The underlying natural soils are generally firm and dense, and will offer good support to the proposed addition on spread footings. Bearing Values Spread footings carried at least 1. foot into the firm undisturbed natural soils and at least 2 feet below the adjacent grade or floor level may be designed to impose a net dead plus live load pressure of 6,000 pounds per square foot. A one-third increase in the bearing value may be used for wind or seismic loads. Adjacent to the existing building, footings LCA O90072.AEO Page 12 should extend to at least the same level as the existing footings. The recommended bearing value is a net value, and the weight of concrete in the footings may be taken as 50 pounds per cubic foot, and the weight of soil backfill may be neglected when determining the downward loads. Footings for minor structures (auxiliary retaining walls and free-standing walls) may be designed to impose a net dead plus live load pressure of 1,500 pounds per square foot at a depth of at least 1 foot below the adjacent grade. Such footings may be established in either properly compacted fill or the natural soils. While the actual bearing value of any required fill will depend on the material used and the compaction methods employed, the quoted bearing values will be applicable if acceptable soils are used and are compacted as recommended. The bearing value of the fill should be confirmed during the grading. Settlement The settlement of the proposed building, supported on spread footings as recommended, will be less than three -fourths inch. Lateral Loads Lateral loads may be resisted by soil friction and by the passive resistance of the soils. A coefficient of' friction of 0.4 may be used between footings or the floor slab on grade and the supporting soils. The passive resistance of the natural soils or properly compacted fill against footings may be assumed to be equal to the pressure developed by a fluid with a density of 300 pounds per cubic foot. A one-third increase in the passive value may be used for wind or seismic loads. The frictional resistance and the passive resistance of the soils may be combined without reduction in determining the total lateral resistance. LCA O90072.AEO Page 13 Footing Observation To verify the presence of satisfactory soils at design elevations, all footing excavations should be observed by personnel of our firm. Footings should be deepened as necessary to extend into satisfactory soils. Where it is necessary to deepen a footing below the design depth, the overexcavated portion should be backftlled with concrete. Soil backfill above the footings and utility trench backfill should be mechanically compacted; flooding should not be permitted. The exterior grades should be sloped such that surface water will drain away from the foundations. Inspection of footing excavations may also be required by the appropriate reviewing govern- mental agencies. The contractor should be familiar with the inspection requirements of the reviewing agencies. EXCAVATION AND SLOPES Excavation approximately 12 feet deep will be required for the service level. Temporary unsurcharged slopes i,,ay be made at 1:1 in Lieu of shoring. Care should be taken in excavating adjacent to the existing building so as to avoid damage to the building. All applicable requirements of the California Construction and General Industry Safety Orders, the Occupational Safety and Health Act of 1970, and the Construction Safety Act should be met. Where sloped embankments are used, the tops of the slopes should be barricaded to prevent vehicles and storage loads within 5 feet of the tops of the slopes. If the temporary construction embankments are to be maintained during the rainy season, berms are suggested along the tops of the slopes as necessary to prevent runoff water from entering the excavation and eroding the slope faces. These recommended temporary excavation slopes do not preclude possible local raveling and sloughing. LCA 090072.AEO Page 14 SHORING Where there is not sufficient space for sloped embankments, shoring will be required. For design of cantilevered shoring, a triangular distribution of lateral earth pressure may be used. It may be assumed that the retained soils with a level surface behind the cantilevered shoring will exert a lateral pressure equal to that developed by a fluid with a density of 25 pounds per cubic foot. For the design of soldier piles spaced at least two diameters on centers, :he allowable lateral tearing value (passive value) of the soils below the level of excavation may be assumed to be 600 pounds per square foot per foot of depth, up to a maximum of 6,00ft pounds per square foot. To develop the full lateral value, provisions should be taken to assure firm contact between the soldier piles and the undisturbed soils. The concrete placed in the soldier pile excavations may be a lean -mix concrete. However, the concrete used in that portion of the soldier pile which is below the planned excavated level should be of sufficient strength to adequately transfer the imposed loads to the surrounding soils. Continuous lagging will be required between soldier piles. If the clear spacing between soldier piles does not exceed 4 feet, the lagging may be omitted in the stiff clay soil. We should approve any areas where lagging is omitted. All applicable requirements of the California Construction and General Industry Safety Orders, the Occupational Safety and Health Act of 1970, and the Construction Safety Act should be met. BUILDING WALLS BELOW GRADE For design of the walls below grade as planned, where the surface of the backfill is level, it may be assumed that the soils will exert a lateral pressure equal to that developed by a fluid with a density of 30 pounds per cubic foot. LCA O90072.AEO Page 15 The upper 10 feet of the basement walls should be designed for an additional lateral p essure of 100 pounds per square foot due to adjacent traffic, unless the traffic is kept at least 10 feet away from the walls. All required backfill should be cachanically compacted in layers; flooding should not be permitted. Proper compaction of the backfill will be necessary to minimize settlement of the backfill and to minimize settlement of overlying slabs, walks, and paving. Backfll should oe compacted to at least 90% of the maximum dry density obtainable by the ASTM Designation D1557-78 method of compaction. Backfll soils should consist of relatively :ton -expansive soils such as a silty sand. The backfill soils should contain sufficient fines so as to be relatively impermeable when compacted. Some settlement of the backfill should be anticipated, and any utilities supported therein should be designed to accept differential settlement, particularly at the points of entry to the buildings. Also, provisions should be made for some settlement of concrete walks on grade supported on backfill. Compaction of the backfill and providing good surface drainage will minimize but not prevent infiltration of water into the backfill. Building walls below grade should be waterproofed or at least dampproofed, depending upon the degree of moisture protection desired. We recommend that walls below grade be drained. Such drainage could consist of a 4-inch-diameter perforated pipe, placed with perforations down, surrounded by filter material loc :ed at the base of the wall backfill. The drain should be sloped to drain to a sump or other drainage device. GRADING Site Preparation and Compaction To provide support for slabs on grade, any existing fill and unsuitable soils should be excavated and replaced as properly compacted fill. The on -site clay soils near the existing grade should be excavated as necessary to allow the placement of at least 1 foot of relatively non -expansive material beneath concrete walks and slabs. LCA 090072.AEO Page 16 After excavating as recommended, the exposed soils should be carefully inspected to verify the removal of all unsuitable deposits. Next, the exposed soils should he scarified to a depth of 6 inches, brought to optimum moisture content, and rolled with heavy compaction equipment. At least the upper 6 inches of exposed soils should be compacted to at least 90% of the maximum dry density obtainable by the ASTM Designation D1557-78 method of compaction. After compacting the exposed soils, all required fill should be placed in loose lifts not more than 8 inches in thickness and compacted to at least 90%. The moisture content of the on - site clay soils at the time of compaction should be brought to between 2% and 4% over optimum moisture content. The n)isture content of the relatively non -expansive soils should vary no more than 2% below or above optimum moisture content. Material for Fill The on -site soils, less any debris or organic matter within existing fill, may be used in compacted fills. Because of their expansive characteristics, however, the on -site clay soils should not be placed within 1 foot of subgrade level beneath concrete walks and slabs. Any required imported fill and at least the upper 1 foot of fill should consist of relatively non - expansive soils with an Expansion Index of less than 35. Field Observation The reworking of the upper soils and the compaction of all required fill should be observed and tested by a representative of our firm. The observation and testing should include: • Observe the clearing and grubbing operations to assure that all unsuitable materials have been properly removed. • Observe the exposed subgrade in areas to 'ceive fill and in areas where excavation has resulted in the desired finished subgrade, observe proofrolling, and delineate areas requiring overexcavation. • Perform visual observation to evaluate the suitability of on -site and import soils for fill placement; collect and submit soil samples for required or recommended laboratory testing where necessary. LCA O90072.AEO Page 17 Perform field density and compaction testing to determine the percent- age of compaction achieved during fill placement. Observe and probe foundation materials to confirm that suitable bearing materials arc present at the design foundation depths. The governmental agencies having jurisdiction over the project should be notified prior to commencement of grading so that the necessary grading permits may be obtained and arrangements may be made for the required inspection(s). FLOOR SLAB SUPPORT If the grading recommendations are followed, the service level slab may be supported on grade. if a floor covering that would be critically affected by moisture, such as vinyl, is to be used, we suggest that the floor slab be supported on a 4-inch-thick Layer of gravel or on an impermeable membrane as a capillary break. A suggested gradation for the gravel layer would be as follows: Sieve Size Percent Passim, 3/4" 90 - 100 No. 4 0 - 10 No.100 0-3 If the membrane is used, a low -slump concrete should be used to minimize possible curling of the slabs. The concrete slabs should be allowed to cure properly before placing vinyl or other moisture -sensitive floor covering. LCA O90072.AEO Page 18 PAVING Compaction of the subgrade to at least 90%, including trench backfills, will be important for paving support. The preparation of the subgrade should be done immediately prior to the placing of the base course. Proper drainage of the paved areas should be provided since this will reduce moisture infiltration into the subgrade and increase the life of the paving. The paving design thickness will depend on the subgrade soils and on the Traffic Index. If the subgrade soils consist of sandy soils, a lesser paving section may be used than if the soils consist of clay soils. Design data for different traffic indices are presented on the following page; if needed, design data for other traffic indices can be provided. The following recommendations are based on the Caltrans Method adopted by Orange County. Assuming that the subgrade will consist of the on -site clay soils, compacted to at least 90% as recommended, the following paving sections may be used: Type of Use Traffic Index Asphaltic Paving (inches) Gravel Base (inches) Driveways subject to automobile traffic 5 4 9 Driveways and areas subject to light truck traffic 6 4 13 Driveways and areas subject to heavy truck traffic 7 5 15 LCA O90072.AEO Page 19 Assuming that the subgrade will consist of sandy soils, or if it is decided to place a layer of non -expansive material, the following paving sections may be used. It is assumed that such a subgrade will have an "R" value of at least 40; this must be verified during site grading. Type of Use Traffic Index Asphaltic Paving (inches) Gravel Base (inches) Thickness of Non -expansive Material (inches) Driveways subject to automobile traffic 5 3 4 12 Driveways and areas subject to light truck traffic 6 3 7 12 Driveways and areas subject to heavy truck traffic 7 4 8 12 The base course should meet the specifications for Class 2 Aggregate Base as defined in Section 26 of the State of California, Department of Transportation, Standard Specifica- tions, dated July 1984. Alternatively, the base course could mee: the specifications for untreated base as defined in Section 200-2 of the 1985 edition of the Standard Specifica- tions for Public Works Constr.:ction. The base course should be compacted to at least 95%. For design of portland cement concrete paving, the modulus of subgrade reaction (k) for the on -site clay soils may be assumed to be 100 pounds per cubic inch. Where the subgrade consists of on -site sandy soils or select predominantly granular soils, the modulus of subgrade reaction (k) may be assumed to be 200 pounds per cubic inch. These values were estimated from published empirical relationships. LCA O90072.AEO Page 20 BASIS FOR RECOMMENDATIONS The recommendations provided in this report are based upon our understanding of the described project information and on our interpretation of the data collected during the subsurface exploration. We have made our recommendations based upon experience with similar subsurface conditions under similar loading conditions. The recommendations apply to the specific project discussed in this report; therefore, any change in building loads, building location, or site grades should be provided to us so that we may review our conclusions and recommendations and make any necessary modifications. The recommendations provided in this report are also based upon the assumption that the necessary geotechnical observations and testing during construction will be performed by representatives of our firm. The field observation services are considered a continuation of the geotechnical investigation and essential to verify that the actu:soil conditions are as anticipated. This also provides for the procedure whereby the client can be advised of unanticipated or changed conditions that would require modifications of our original recommendations. In addition, the presence of our representative at the site provides the client with an independent professional opinion regarding the geotechnically related construction procedures. If another firm is retained for the geotechnical observation services, our professional responsibility and liability would be impaired. -oOo- y 0 3 e A w r Q 3 0 O LL LEXISTING ASPHALTIC PAVING x67.4 EXISTING H1y': l x22.3 x747 EXISTING ASPHALTIC PAVING -� PROPOSED PARTIAL BASEMENT (SERVICE LEVEL) (F.F.E. = 64) 61.6 x61.0 x60.8 x60.9 PROPOSED FIRST LEVEL (F.F.E. = 79) 21 60.5 x x65.5 x64 62.8 APPROACH TO LOADING DOCK (F.F.E. = 61) 62.5 / 60.6 x 3 • 60.6 81.0 60.0 x /EN.ILATION PLANT x 76.1 ®2 X 76.1 EXISTING LOADING DOCK (F.F.E. = 64) EXISTING EMERGENCY ROOM (F.F.E.= 64) REFERENCE: TOPOGRAPHY MAP (UNDATED) BY ROBERT BEIN.

Each of the borings was drilled to a depth of about 30 feet below the existing grade using 20-inch- diameter bucket -type equipment. Caving of the boring walls did not occur during drilling, and casing or drilling mud was not used to extend the borings to the depths drilled. The materials encountered were logged by our field technician, and undisturbed and loose samples were obtained for laboratory inspection and testing. The logs of the borings are presented on Plates A-1.1 through A-1.3; the depths at which undisturbed samples were obtained are indicated to the left of the boring logs. The energy required to drive the sampler 12 inches is indicated on the logs. The soils are classified in accordance with the Unified Soil Classification System described on Plate A-2. LABORATORY TESTS The field moisture content and dry density of the soils encountered were determined by performing tests on the undisturbed samples. The results of the tests are shown to the left of the boring logs. Direct shear tests were performed on selected undisturbed samples to determine the strength of the soils. The tests were performed at field and increased moisture contents and at various surcharge pressures. The yield -point values determined from the direct shear tests are presented on Plate A-3, Direct Shear Test Data. LCA 090072.AEO Page A-2 Confined consolidation tests were performed on three undisturbed samples to determine the compressibility of the soils. Water was added to one of the samples during the test to illustrate the effect of moisture on the compressibility. The results of the tests are presented on Plates A-4.1 and A-0.2, Consolidation Test Data. The optimum moisture content and maximum dry density of the upper soils were determined by performing a compaction test on a sample obtained from Boring 1. The test was performed in accordance with the ASTM Designation D1557-78 method of compaction. The results of the test are presented on Plate A-5, Compaction Test Data. The Expansion Index of the soils was determined by testing two samples in accordance with the Uniform Building Code Standard No. 29-2 method. The results of the tests are shown on Plate A-6, Expansion Index Test Data. Soil corrosivity studies were performed for us by M. J. Schiff and Associates. The Schiff report is presented on Plates A-7.1 through A-7.4. -000- s 1- O 0 0 w 0 O90072,AEO 0 0 0 m 0 L a m m o E o 00 m m C O O 0 U O U m o o m m c o c 0 0 U m m N '0 c o .0 coy m a, c 3 o'C n 0c 0 - m O m c Ug 0 o m -0 m a m m m 0 3 meo c m N F F L • 0 Z ELEVATION (ft.)

The Safety Element for Orange County (1987) and the City of Newport Beach General Plan (1972) were reviewed as part of our literature analysis. This appendix presents additional background information regarding faults and ground shaking. FAULTS The numerous faults in Southern California include active, potentially active, and inactive faults. The criteria for these major groups, as established by Slemmons (1979), are presented in Table B-1. Table B-2 presents a listing of active faults in Southern California within 100 miles of the site with the distance in miles and direction from the site to the site and the nearest point on the fault. Table B-3 provides a similar listing for potentially active faults. No faults or fault -associated features were observed on the site during our field reconnaissance. Active Faults The nearest active fault to the site is the North Branch fault of the Newport -Inglewood fault zone- The actual position of the fault trace through the Newport Peninsula has not been firmly established; however, the Geologic -Seismic Study for the Newport Beach General Plan (1972) projects the fault as passing about 0.5 mile southwest of the site and trending northwest, as shown on Plate 3. LCA 090072.AEO Activity Classification and Definition Page B-2 TABLE 8-1 CRITERIA FOR CLASSIFICATION OF FAULTS WITH REGARD TO SEISMIC ACTIVITY (After D. B. Slemmons, 1979) Active - a tectonic fault with a history of strong earthquakes or surface faulting, or a fault wirh a short recurrence inter- val relative to the life of the planned project. The recur- rence interval used to define activity rate may vary ac- cording to the consequence of activity. Potentially Active - a tectonic fault without historic surface offset, but with a recurrence ircerval that could be suffi- ciently short to be significant to the particular project. Activity Uncertan - a fault with insufficient evidence to define past activity or recurrence inter- val. The following classifi- cations can be used until the results of additional studies provide definitive evidence. Tentatively Active - predomi- nant evidence suggest that the fault may be active even though its recurrence ;tterval is very long or poorly di fined. Tentatively inactive - predom- inant evidence suggests that fault is not active. Inactive - a fault along which it can be demonstrated that sur- - face faulting has not occurred in the recent past, and that the requirement interval is long enough not to be of signifi- ' ) canoe to the particular project. Criteria Historic (1) Surface faulting and as- sociated strong earth- quakes. (2) Tectonic fault creep or geodetic evidence of fault displacement or defor- mation- No reliable report of historic surface faulting. Geologic (1) Geologically young dep- osits cut by fault. (2) Youthful geomorphelogica] features that are char- acteristic of geologically young displacements along the fault trace. (3)Ground water barriers in geologically young or un- consolidated deposits. (1)Geomorphic features that are characteristic of active faults, but with subdued, eroded, and discontinuous form. (2) Faults not known to cut or displace youngest alluvial deposits, but offset older quaternary deposits. (3) Water barriers in older deposits. (4) Geological setting in which the geometry in re- lation to active or poten- tially active faults suggest similar degree of activity. Seismologic Earthquake epicenter can be assigned with confidence to the fault. Alignment of some earthquake epicenters along or near fault, but assigned locations have low degree of confidence in location. Available information is insufficient to provide criteria that are sufficiently definitive to establish fault activity. This lack of information may be due to the inactivity of the fault or to lack of investigations needed to provide definitive criteria. Available information suggests evidence of fault activity, but evidence is not definitive. Available information suggests evidence of fault inactivity, but evidence is not definitive. No historic activity. Geomorphic features characteristic of active fault zones are not present and earthquakes. geological evidence is available to indicate that the fault has not moved in the recent past and recurrence is not likely during a time period con- sidered significant to the site. Should indicate age of last movement: Holo- cene, Pleistocene.

CALIFORNIA 91711 3860 714/626-0967 FM 714/621-1419 Re: Soil Corrosivity Study Hoag Memorial Hospital Presbyterian Newport Beach, California Your t090072.AEO, MJS&A 190294 Laboratory tests have been completed on three soil samples we selected from your boring logs for the subject emergency roam expansion project at 301 Newport Boulevard. The purpose of these tests was to determine if the soils may have deleterious effects on underground utilities, hydraulic elevator cylinders, and concrete foundations. The electrical resistivity of each sample was measured in its as -received condition and again with distilled water added to create the standardized condition of saturation. Resistivities are at about their lowest value when the soil is saturated. The samples were chemically analyzed for the major anions and cations, and pH was measured. Test results are shown on Table 1. One of the most useful factors in determining soil corrosivity is electrical resistivity. The electrical resistivity of a soil is a measure of its resist- ance to the flow of electrical current. Corrosion of buried metal _s an electrochemical process in which the amount of metal loss due to corrosion is directly proportional to the flow of electrical current (DC) from the metal into the soil. A soil's resistivity decreases and, therefore, its corrosivity increases as its moisture and chemical contents increase. A commonly accepted correlation between electrical resistivity and corrosivity toward ferrous metals is: Soil Resistivity in ohm -centimeters Corrosivity Category 0 to 1,000 severely corrosive 1,000 to 2,000 corrosive 2,000 to 10,000 moderately corrosive over 10,000 mildly corrosive Electrical resistivities measured in the laboratory with as -received moisture content were in the moderately corrosive category, When saturated, they dropped into corrosive and severely corrosive categories. Soil pH values varied from 8.0 to 8.6 which are moderately to strongly alka- line. This is not significant in evaluating corrosivity in this case unless lead or aluminum will be used underground.

This site is classified as severely corrosive to ferrous metals. Page 2 The life of buried materials depends on thickness, strength, loads, construc- tion details, and soil moisture as well as soil corrosivity and is, therefore, difficult to predict. 0f more practical value are corrosion control methods that will increase the life of the material at a reasonable cost. The follow- ing corrosion control measures are recommended to prolong the life of materi- als buried in these soils. Underground steel utilities should be abrasive blasted and given a high quali- ty protective coating such as extruded polyethylene, a tape coating system, hot applied coal tar enamel, or fusion bonded epoxy, and cathodic protection should be applied. Buried steel wiping must be electrically insulated from dissimilar metals, cement -mortar or concrete coated steel, and above ground steel pipe to prevent dissimilar metal corrosion cells and to facilitate the application of cathodic protection. Underground steel pipe with rubber gasketed, mechanical, grooved end, or other nonconductive type joints must be bonded for electrical continuity for corro- sion monitoring and cathodic protection. Hydraulic elevator cylinders should be well coated as described above. Each cylinder should be isolated from building metals by installing dielectric material between the piston platen and car and also in the oil line. The oil line should be placed above ground if possible but, if underground, should be protected as described above for steel utilities. Cathodic protection is recommended for hydraulic cylinders or, as an alternate, each cylinder may be placed in a plastic casing with a plastic watertight seal at the bottom. Cast or ductile iron pipe, valves, and fittings should be encased in an 8 mil polyethylene tube or wrap per AWWA Standard C105/ANSI 21.5. As an alternate, iron piping not under pressure, such as sewers and drains, may be bedded and backfilled with cement slurry or alkalized sand (25 pounds hydrated lime mixed into each cubic yard of sand) at least 3 inches thick surrounding the pipe. Underground iron pipe should also be electrically insulated from dissimilar metals and above ground iron pipe. Bare copper tubing should be bedded and backfilled in sand at least 3 inches thick surrounding the pipe. However, if a recirculating hot water system is installed underground, buried hot copper tubing would be subject to corrosion by a thermogalvanic cell. The best corrosion control measure would be to place the hot copper tubing above ground. If buried, bare copper tubing should be encased in impermeable, unstretched, nonshrink insulation with the joints and seams sealed. PLATE A-7.2 LeROY CRANDALL & ASSOCIATES October 19, 1990 MJS&A 990294 Page 3 No special precautions are required for reinforced concrete, asbestos -cement, or plastic piping placed underground from a corrosion viewpoint. However, any iron valves or fittings should be protected as mentioned above. Where metallic pipelines penetrate concrete structures such as building floors or walls, plastic sleeves, rubber seals, or other dielectric material should be used to prevent pipe contact with the concrete and reinforcing steel. On any type of pipe, bare steel appurtenances such as bolts, joint harnesses, or flexible couplings should be coated with a coal tar or rubber based mastic after assembly. Standard construction practices and concrete mixes may be used for concrete in contact with these soils using type 2 cement. The scope of this study is limited to a determination of soil corrosivity and its general effects on materials likely to be used for construction. If the architect and/or engineers desire more specific information, designs, specifi- cations, or review of design, we will be happy to work with them as a separate phase of this project.

Available information on the North Branch and other faults of the Newport -Inglewood zone indicate that there has been no displacement of the Holocene age Talbert aquifer underlying Santa Ana Gap, which is estimated to be less than 10,000 years old. The Pleistocene and older formations have been affected by faults of the Newport -Inglewood zone. There is some evidence in Bolsa and Sun..et Gaps, farther to the northwest, that Holocene deposits have been disturbed by movement on the North and South Braaches of the Newport -Inglewood fault zone. The Whittier fault is a southeast trending fault along the south edge of the Puente Hills, 21 miles north-northeast of the site. The 1929 Whittier earthquake may have originated on this fault, although some geologists believe that movement on the Norwalk fault was the cause. The Elsinore fault is located on the northeast side of the Santa Ana Mountains. Several earthquakes have originated along this fault system. The largest was in 1910 with a magnitude of about 6.0. The northern terminus of the Elsinore fault is about 26 miles northeast of the site. The San Andreas fault is the best known and most significant fault in California. This fault is about 51 miles northeast of the site. Potentially Active Faults The Pelican Hill fault is located about 3 miles east of the site. A branch of the fault has displaced higher marine terrace deposits in the San Joaquin Hills, indicating upper Pleistocene or younger activity. Holocene activity has not been established; therefore, the fault is considered potentially active. LCA O90072.AEO Page B-6 The potentially active El Modeno fault is located about 15 miles north of the site. The fault is a steeply dipping normal fault about 9 miles in length, which has about 2,000 feet of uplift on its eastern side. Movement on the fault has been inferred during Holocene time, suggesting the fault is active; however, further study is needed to confirm this_ ThePeralta Hills fault is located approximately 15 miles north of the site. This reverse fault trends east -west and dips to the north. The fault is approximately 5 miles in length and has a sinuous surface trace across the southern Peralta Hills, which lie northeast of the City of Orange. Pleistocene age offsets arc known along this fault; on this basis this fault is classified as potentially active. Some geologists believe that the Peralta Hills fault may be active based upon recent Carbon 14 dating of known offsets estimated to be 3,000 to 3,500 years old (Fife and Bryant, 1983). Inactive Faults The Shady Canyon fault is located about 6.7 miles northeast of the property. Miller and Tan (1976) show that the youngest rocks cut by the fault arc middle Miocene in age. Miller and Tan (1976) suggest that a lineament in the topographic expression of the marine terrace might be due to the fault. However, no other publications consider the Shady Canyon fault potentially active. Until more definite information is developed, wr: will consider the Shady Canyon fault to be inactive. SEISMICITY The seismicity of the region surrounding the site was determined from a computer search of a magnetic tape catalog of earthquakes. The catalog of earthquakes included those compiled by the California Institute of Technology for the period 1932 to 1987, and earthquakes compiled by Richter and the U.S. National and Atmospheric Administration (NOAA) for the period 1812 to 1931. The computer printout of the earthquakes is presented as Table B-4. The historic seismic record indicates that 296 earthquakes of Richter magnitude 4.0 and greater have occurred between 1932 and 1987 within 100 kilometers (62 miles) of the site. LCA O90072.AEO Page B-7 The information listed for each earthquake found in Table B-4 includes date and time in Greenwich Civil Time (GCT), location of the epicenter in latitude and longitude, quality of epicentral determination (Q), depth in kilometers, and magnitude. Where a depth of 0.0 is given, the solution was based on an assumed 16-kilometer focal depth. The explanation of the letter code for the quality factor is presented on the first page of the table. GROUND SHAKING Duration of Ground Shaking Movements on any of the above -described active and potentially active faults could cause ground shaking at the site. The relationship between the magnitude of an earthquake and the duration of strong shaking that results has been investigated by Bolt (1973). The relationship is set forth in Table B-5. The period of strong shaking is defined as that period of time when the acceleration of the ground due to seismic waves is in excess of 0.05g.

Postulated design earthquakes were selected in accordance with the seismic criteria set forth in the "Hospital Code" of the State of California. Two maximum credible earthquakes were selected. The maximum credible earthquake constitutes the maximum earthquake that appears to be reasonably capable of occurring under the conditions of the presently known geological framework; the probability of such an earthquake occurring during the lifetime of the facility may be low. The descriptions of these earthquakes are presented in Table B-6, Postulated Maximum Credible Earthquakes (MCE). Earthquake A B TABLE B-6 POSTULATED MAXIMUM CREDIBLE EARTHQUAKES Fault San Andreas Newport -Inglewood Distance From Estimated Fault to Site Magnitude (Miles) 8.3 51 7.0 0.5 The Maximum Probable Earthquake (MPE) is considered to be an event having a 20% probability of being exceeded in 100 years. Table B-7 below summarizes the estimated slip rates and MPE of the most significant active and potentially active faults affecting the site. LCA O90072.AEO Page B-9 TABLE B-7 POSTULATED MAXIMUM PROBABLE EARTHQUAKES Fault (in alphabetical order) Slip Rate (mm/year) Magnitude Chino 0.1 5.8 Cucamonga 3 6.5 El Modeno 0.01 <5.0 Elsinore 4.5 7.4 Elysian Park Structure 0.5 6.5 Malibu Coast 0.7 6.6 Newport -Inglewood 1 6.8 Norwalk 0.01 <5.0 Palos Verdes 0.3 6.3 Pelican Hill 0.01 <5.0 Peralta Hills 0.01 <5.0 Raymond 0.13 5.9 San Andreas 25 8.1 San Fernando Zone 1 6.5 San Gabriel 4 7.4 San Jacinto Zone 10 7.5 San Jose 0.01 <5.0 Sierra Madre 4 7.4 Verdugo 0.01 <5.0 Whittier 1 6.8 The slip rates were estimated from data published by Ziony and Yerkes (1985) and Wesnousky (1986). Using the slip rates, the accumulated slip over an approximate 450 year period (corresponding to 20% probability of exceeding in 100 years assuming Poisson probability theory) was determined. Using the surface displacement versus magnitude relationships developed by Slemmons (1979), the magnitude for each significant fault was determined as summarized above. LCA O90072.AEO Page B-10 Estimated Peak Ground Motion Values Thee peak ground accelerations for the subject site and postulated design earthquakes are based on the studies by Seed (1987), who developed peak ground acceleration relationships for four broad site classifications: rock, stiff soil, deep cohesionless soil, and soft to medium soil deposits. Based on a review of the results of the boring logs, prior nearby downholc seismic surveys, and static laboratory tests, this site is classified as being a stiff soil site. The peak ground acceleration is estimated to be 0.14g for MCE "A" and 0.63g for MCE "B"; the accelerations were estimated by the attenuation relationship for rock and local site conditions developed by Seed (1987). It is conceivable that the peak ground accelerations could be greater than these estimates, which are mean estimates. The maximum ground accelerr t•on was estimated for each postulated MPE, and the maximum ground acceleration, according to Seed, is about 0.62g. The MPE peak ground accelerations were computed based on the ciosest distance from the site to a fault, which is a conservative assumption.

Our Los Angeles office has provided us with a subgrade soil R-value for use in the design. A traffic index (T.I,) is also needed for the calculations. In an effort to develop a T.I„ we contacted the receiving department at the hospital to get some idea of the number of heavy vehicles (trucks) that deliver materials and equipment to the hospital In a typical week. We were told that approximately 75 trucks per week use the ioading & unloading facilities facing the west road. Using that number and assuming a mix of 2, 3, 4 & 5 axle trucks; adding 5 rubbish collection trucks per week; and allowing for a slight increase over time, we developed a T.I. of 6.0. Because of the imprecise methods used In arriving at the figure, and introducing a safety factor. we arbitrarily increased the T.1, used in the design to 7.0. We were asked to include an alternate section with an asphalt rubber hot mix surface course. Both of the recommended structural sections are presented below. The calculations for both T.I. and pavement section were made using the standard Caltrans design procedure. rin ONlAAANCO..9101 ce,CAmn Ia a tta 10.

ENGINEERING AND ENVIRONMENTAL SERVICES ONE OF THE LAW COMPANIES November 16, 1995 Hoag Memorial Hospital Presbyterian 301 Newport Boulevard, Box 6100 Newport Beach, California 92658-6100 Attention: Mr. Gunther M. Kilfoil Project Manager Gentlemen: Final Report - Geotechnical Inspection Services West Service Road 301 Newport Boulevard Newport Beach, California SCOPE Grading Permit No. G9400220 Plan Check No. 2046-94 (2407.40401.0001) We are pleased to provide our final report for the geotechnical inspection services performed during the development of the west service road at Hoag Memorial Hospital Presbyterian. This report provides: A formal record of our observation and testing of the compacted sub - grade soils; A formal record of our observation and testing of the compacted asphalt paving. The location of the site is shown in relation to an adjacent street and structure on the attached Plot Plan. The periodic observation work was performed during the period of October 12,1994 through March 16, 1995. We previously performed consultation regarding foundation design for the cardiac services addition, located immediately adjacent to the west ip 2407.40401.0001 Page 2 service road, and submitted our recommendations in a report dated December 16, 1992 (O92072.AB). In addition, supplementary geotechnical recommendations were presented in a letter dated February 16, 1994 (O92072.AB), also in regards to the cardiac services addition. We also submitted clarifications for structural section recommendations in a letter dated November 9, 1994, for paving operations at the west service road. Our professional services have been performed using that degree of care and skill ordinarily exercised, unde similar circumstances, by reputable geotcchnical engineers practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional opinions included in this report. The scope of our services did not include either the responsibility for job safety or the function of surveying. The soil -related work was done to the limits and at the locations indicated by stakes and hubs set by others. OBSERVATION AND TESTING OF COMPACTED SOUS The earthwork for the project consisted of compacting the existing subgrade soils to grade the site for the west service road and to provide subgrade support for adjacent walks and for parking lot paving. Also, base cc:•rse was placed and compacted in walkway and paving areas. The specifications required 'bat the soils be compacted to at least 90% of the maximum dry density obtainable by the ASTM Designation D1557-78 (equivalent to UBC 70-1) method of compaction. The base course was to be compacted to at least 95% of the maximum dry density. The existing subgrade soils consisted of silty sand material; imported processed miscellaneous base and crushed miscellaneous base material were utilized in the pavement section. Compaction tests were performed on representative soil samples to establish the maximum dry densities. The tests were performed in accordance with the specified method of compaction, which uses a 1/30-cubic-foot mold in which each of five layers of soil is compacted by 25 blows of a 10-pound hammer falling 18 inches. The results of the compaction tests were used in establishing the degree of compaction achieved during the compaction of the in -place soils and the placement of the base course. 2407.40401.0001 Page 3 The site was stripped and cleared of an existing roadway, curb and gutter sections, and minor hardscape areas. During our periodic observation of the stripping and clearing, underground obstructions scheduled for abandonment were removed. Next, the resultant exposed sub -grade soils were scarified to a depth of 6 inches, brought to approximately optimum moisture content, and compacted. To establish the degree of compaction achieved, ASTM Designation D1556 (equivalent to UBC 70-2) sand -cone field density tests were made when requested as the compaction of the sub -grade soils and base course material progressed. In addition, ASTM Designation D2922-81 (equivalent to UBC 70-5) nuclear gauge in -place density tests were performed at times for the base course material. Where a test indicated less than the required compaction, the soils were reworked and retested until at least the specified degree of compaction resulted. The results of the field density tests are presented in the attached table, Test Results; the approximate locations of the tests are shown on the Plot Plan. OBSERVATION AND TESTING OF ASPHALT PAVING As requested, our field technician observed the asphalt paving placed in the roadway and parking areas. ASTM Designation D2922-81 (equivalent to UBC 70-5) nuclear gauge in- p'ace density tests were performed on the compacted asphalt to establish the degree of compaction achieved. The asphalt paving was to be compacted to at least 95% of the maximum density. A 10,000-ton static roller, a dual 4-ton vibratory roller, and hand -guided vibratory plates were utilized to compact the asphalt. Tne data derived from the performance of the density tests are included in the table of test results; the approximate locations of the tests are shown on the Plot Plan. The asphalt paving consisted of a 2-'/z inch thick base course of 3/4-inch aggregate and a 1-1/2 inch thick surface course of'/ -inch aggregate using AR 4000 asphalt cement. At the owner's request laboratory maximums, provided by the supplier using ASTM Designation D1561, yielded results of 147 and 148 pounds per cubic foot for the 3/4-inch base course and 142 pounds per cubic foot for the 1/2-inch surface course. 2407.40401.0001 Page 4 CONCLUSIONS This final report is limited to the earthwork performed through March 16, 1995, the date of our last periodic observation and/or testing of the soil -related work for the project. The sub -grade soils, base course, and asphalt paving, at the locations and elevations tested by us, were compacted to at least the specified degree of compaction. In our opinion, the geotechnical-related work was performed in general compliance with the project plans and specifications, and the City of Newport Beach Municipal Code and is considered suitable for the intended use. In providing professional geotechnical observations and testing services associated with the development of the project, we have employed accepted engineering and testing procedures, and have made every reasonable effort to ascertain that the soil -related work we observed was carried out in general compliance with the project plans and specifications. We do not guarantee the contractor's work, nor do the services performed by our firm relieve the contractor of responsibility in the event of subsequently discovered defects in his work.

Box 1768 Newport Beach, Califomia 92658-8915 Subject: Response to Comments Proposed Cardiac Services Addition Hoag Memorial Hospital Presbyterian 301 Newport Boulevard Newport Beach, California Law/Crandall Project O92072.AB Dear Mr. Higley: AP Q This letter presents our response to comments in your letter of March 15, 1994, on our consultation report dated December 16, 1992. In addition, to the report, we submitted supplemental letters dated February 9, 1994 and February 16, 1994. The professional opinions presented in this letter have been developed using that degree of care and skill ordinarily exercised, under similar circumstances, by reputable geotechnical consultants prac- ticing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this letter. Comment 1: Provide specific recommendations for remedial grading of unsuitable existing soils and/or uncertified fills in areas where pavements, curb and gutter, patios, etc. are planned in addition to the subject building. Adequate remediation must be accomplished so that the consultant can: a. approve any existing fills to be left in place b. be in a position to render an opinion that the site earthwork at completion is suitable for its intended use. Caveats such as "if some potential for future settlement of improvements is acceptable..." cannot be accepted in lieu of the consultants approval of the existing fills and the proposed earthwork as required by the Municipal Code. 200 CITADEL DRIVE • LOS ANGELES, CA 90040 (213) 089-5300 • FAX (213) 721-6700 0 E0P Mf LAW COMPANIES e City of Newport each April 4, 1994 Page 2 Response: Recommendations regarding grading within the building area are presented in our December 16 report and February 16 letter. Our recommendations are considered applicable to areas outside of the building area such as paving, curb and gutter, and patio areas. The existing fill soils are not considered suitable for support of the proposed building or for support of the improvements. The fill soils should be excavated and replaced with properly compacted fill soils. Our prior report and letter should be referred to for additional details on site grading. Comment 2: Provide information about general site geology, seismicity, etc. Response: We previously performed a preliminary geotechnical evaluation of the hospital campus for preparation of the master plan and submitted the results in a report dated May 20, 1991 (O89034.AEO). The report discusses site geology and seismicity and is considered applicable to the proposed addition project. We have included a copy of this report with this letter for your review. No faults or fault - associated features were observed on the site of the proposed addition, and no known active or potentially active faults pass beneath the site. Accordingly, the possibility of surface rupture due to faulting beneath the site is considered low. Although the site could be subject to severe ground shaking in the event of a major earthquake, this hazard is common to Southern California and the effects of the shaking can be minimized by proper structura: design and construction. Continent 3: Reports to be signed by the project engineering geologist. Response: Please refer to the signatures listed below and on our report of geotechnical evaluation previously discussed. In addition, we provided recommendations for shoring in our February 16 letter. At this time, we understand that shoring will not be required. Our recommendations regarding shoring can be disregarded. City of Newport Beach April 4, 1994 Page 3 We trust that this letter satisfies your current needs require additional information.

In addition to the report, we submitted supplemental letters dated February 9, February 16, and April 4, 1994. The professional opinions presented in this letter have been developed using that degree of care and skill ordinarily exercised under similar circumstances, by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this letter. In our April 4, 1994 letter, we stated that all existing fill soils within the site, including hardscape and paving areas, should be excavated and replaced with properly compacted fill. We have subsequently reviewed the available plans and information and conclude the only the upper subgrade soils at the site will require removal and recompaction. After clearing the site, the upper 2 feet of subgrade soils within paving, curb and gutter, and patio areas outside the proposed building limits should be excavated. After excavating, the exposed soils should be observed by personnel from our firm and any unsuitable deposits should be removed. The recommendations presented in our December 16, 1992 report regarding recompaction of fill soils are still considered applicable. In our opinion, if the subgrade is prepared as recommended it will be suitable for its intended use. In our February 16, 1994 letter, we provided recommendations for temporary shoring. As stated in our April 4, 1994 letter, we currently understand that shoring will not be required. According to personnel with Hoag Hospital, the continuous foundations of the existing structure extend well below the anticipated depth of fill removal within the site. Therefore, any excavation within the proposed building area may be made immediately adjacent to the existing continuous wall footings and will not 131 EAST BALL ROAD. SURE 104 ANAHEIM.

HL 909988 G.P. G9200008 P.C. No. PC 47-92 We have completed geotechnical inspection services at the site of the subject project. This fmal report provides: • A formal record of our observation and testing of the compacted fill placed to provide subgrade support for concrete and asphaltic paving, and of the asphaltic paving placed in the newly paved areas. • Confirmation of our observation and approval of the foundation excavations. The location of the site is shown in relation to existing structures en the attached Plot Plan. The observation work was performed periodically as requested between February 1, 1993 and June 14, 1995. We performed a geotechnical investigation of the site and submitted our recommendations in a report dated November 7, 1990 (Our Job No. 090072. AEO). This final report is limited to the earthwork performed through June 14, 1995, the date of our last observation and/or testing of the soil -related work for the project. The fill, at the locations and 200 CITADEL ORIVE • LOS ANGELES, CA 90040 (213) 889E300 • FAX (213) 721.0700 ouEOF,AE UVdCCMAIA1S xsp Hoag Memorial Hospital Presbyterian - Geatecloucal Inspection Services January 11, 1996 Law/Crandall Project 2681,30107.0001 elevations tested by us, was compacted to at least the specified degree of compaction. Also, the foundation excavations extended into satisfactory soils. In our opinion, the soil -related work was performed in general accordance with the project plans, specifications, and the City of Newport Beach Municipal Code and is considered suitable for the intended use. Our professional services have been performed using that degree of care and skill ordinarily exercised, under similar circumstances, by reputable geotechnical engineers practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional opinions included in this report. The scope of our services did not include surveying or the responsibility for job safety. The soil -related work was performed to the limits and at the locations indicated by stakes and hubs set by others. 4 OBSERVATION AND TESTING OF COMPACTED FILL This section describes our observation and testing of compacted fill placed as part or the project earthwork. LOCATIONS The earthwork for the project consisted of placing compacted fill to grade the site and provide subgrade support for adjacent walks, curbs and r otters, a loading dock, and access road paving areas. The grading work included placing compacted soils as backfill against walls below grade, in rampways, and in trenches for utility line installations. Also, base course was placed and compacted in areas to be paved. 2 itsb Hoag Memorial Hospital Presbyterian - Geotechnical Inspection Services January 11, 1996 Law/Crandall Project 2681.30107.0001 FILL MATERIALS The materials used for the required filling consisted of on -site silty sand, silty sand with some clay, and imported Class II base materials. Crushed 3/4-inch rock was also used as backfill at selected locations. COMPACTION SPECIFICATIONS The specifications required that the fill be compacted to at least 90% of the maximum dry density obtainable by the ASTM Designation D1557-78 (equivalent to UBC 70-1) method of compaction. The base course was to be compacted to at least 95 % of the maximum density. Compaction tests were performed on representative samples of the soils to establish the maximum dry densities. The tests were performed in accordance with the specified ASTM Designation D1557-78 method of compaction, which uses a 1/30-cubic-foot mold in which each of five layers of soil is compacted by 25 blows of a 10-pound hammer falling 18 inches. The results of the compaction tests were used in establishing the degree of compaction achieved during the placing of the fill. The soil type and source, maximum density, and optimum moisture content of the fill materials are given in the attached Table 1, Soil Classification and Compaction Data. PLACEMENT AND COMPACTION OF FILL After the site was stripped and cleared, excavation up to approximately 15 feet below the existing grade was performed within the building area for the service level. The excavation was established in firm natural soils. Temporary unsurcharged construction slopes were made at 1:1. Loose subgrade soils were removed in the areas to be paved with asphalt or concrete. The upper clay soils in concrete paving areas were removed and replaced with relatively non -expansive soils. Following excavation, the exposed soils were scarified to a depth of 6 inches, brought to near - optimum moisture content, and rolled with heavy compaction equipment. The required fill materials 3 Hoag Memorial Hospital Presbyterian - Geotechnical Inspection Services January 11, 1996 Law/Crandall Project 2681.30107.0001 were then placed in loose lifts approximately 8 inches in thickness, t sought to near -optimum moisture content by conditioning the materials, and compacted with a loader and a hand -guided impact compactor. Areas to receive backfdl were first cleared of construction debris and loose soils; the required backfdl soils were then placed in loose lifts approximately 8 inches in thickness, brought to near - optimum moisture content, and compacted with a hand -guided impact compactor, a sheepsfoot roller, and a hydraulic compactor. A subdrain system was also installed at the base of the basement walls. The installation of the subdrain was observed and approved by others. FIELD DENSITY TESTING To establish the degree of compaction achieved, ASTM Designation D1556 (equivalent to UBC 70- 2) sand -cone field density tests and ASTM Designation D2922 (equivalent to UBC 70-5) nuclear gage field density tests were made as the filling progressed. Where a test indicated less than the required compaction, the soils were reworked and retested until at least the specified degree of compaction resulted. Test data are given in Table 2, Test Results. The Plot Nan shows the approximate locations of the tests. INTERIM REPORT An interim report of rough grading to reach the design building elevations for the project was issued on March 10, 1993 (2681.30107.0001). OBSERVATION OF FOUNDATION EXCAVATIONS The following foundation design recommendations were presented in our geotechnical investigation report: 4 ka kri Hoag Memorial hospital Presbyterian - Geotedw'cal Inspection Services January 11, 1996 Law/Crandall Project 2681.30107.0001 Spread footings carried at least 1 foot into the firm undisturbed natural soils and at least 2 feet below the adjacent grade or floor level may be designed to impose a net dead plus live load pressure of 6,000 pounds per square foot. A one-third increase in the bearing value may be used for wind or seismic loads. Adjacent to the existing building, footings should extend to at least the same level as the existing footings.... Footings for minor structures (auxiliary retaining walls and free-standing walls) may be designed to impose a net dead plus live load pressure of 1,500 pounds per square foot at a depth of at least 1 foot below the adjacent grade. Such footings may be established in either properly compacted fill or the natural soils. Excavations were made for conventional spread footings to support the building and selected retaining walls. Our field technician observed and probed the footing excavations to confirm that the soils were properly compacted fills or undisturbed natural materials recommended for foundation support. At the time of our observation, loose soils had been removed from the excavations. After observations indicated satisfactory conditions, written notice of our approval was left at the job site for the information of responsible parties. OBSERVATION AND TESTING OF ASPHALTIC PAVING As requested, our field technician observed the asphaltic paving placed in the newly paved areas, and performed ASTM Designation D2922-81 (equivalent to UBC 70-5) nuclear gage in -place density tests to establish the degree of compaction achieved. The asphaltic paving was to be compacted to at least 95% of the maximum density. The asphaltic concrete consisted of 1/2-inch aggregate using AR4000 asphalt cement At the time of delivery, the temperature of the asphalt ranged from 265° to 290° Fahrenheit. A value of 146 pounds per cubic foot was used for the maximum density. The paving was compacted with 5- to 10- ton rollers. The nuclear gage in -place density test results are given in the attached table; the approximate locations of the tests are shown on the Plot Plan. 4 5 Hoag Memorial Hospital Presbyterian - Ceotechnical Inspection Services Law/Crandall Project 2681.30107. 0001 January 11, 1996 In providing professional geotechnical observation and testing services associated with the development of the project, we have employed accepted engineering and testing procedures and made a reasonable effort to evaluate that the soil -related work was carried out in general compliance with the project plans and specifications. Although our observation did not reveal obvious deficiencies, we do not guarantee the contractor's work, nor do the services performed by our firm relieve the contractor of responsibility in the event of subsequently discovered defects in the contractor's work.
