Section 1 – Introduction
The Orange County Sanitation District (OC San) owns, operates, and maintains a series of wastewater pump
stations and corresponding Newport Force Main (NFM) network along the Pacific Coast Highway (PCH) in the
City of Newport Beach (City), California. The network conveys wastewater to the Plant No. 2 wastewater
treatment facility in Huntington Beach. The existing Bay Bridge Pump Station (BBPS) is the furthest upstream
pump station of the NFM network.
The BBPS is located within the City on the inland (north) side of PCH, east of the channel. The force mains (FMs)
associated with the BBPS pass under PCH to the south, then west under the channel, terminating in a valve vault
west of the channel on the south side of PCH.
The BBPS and associated FMs are critical elements to OC San’s Newport Beach collection backbone, therefore
the facility must be capable of continuous service to the community and avoid spills for the next design lifespan.
OC San proposes the BBPS Replacement Project (Project) to replace the existing BBPS and associated FMs for
the following reasons:
To optimize flow conveyance to meet updated minimum flows, average daily flows, and peak wet weather
flows.
To increase reliability. The existing facilities are 50 years old, near the end of their useful life and were
designed under outdated seismic, electrical, and safety codes.
To improve system efficiency, provide odor control, update automation, improve interior access and
ergonomics for safety and better maintainability.
To Increase vehicular safety for OC San Operations & Maintenance personnel where safe entry and exit
can be made, and maintenance crews and drivers can easily access the site.
This memorandum documents the construction phase implementation, construction requirements, and
construction quality control, and traffic control associated with the Project. The memorandum also includes a
construction schedule of the Project as currently planned. A construction management summary table has been
developed in Appendix A, including the preliminary construction phases, construction schedule, construction
hours, potential material storage, employee requirements and potential parking locations, and activities that
require traffic control on PCH.

Section 2 – Construction Requirements
2.1 Construction Easements and Laydown
2.1.1 Easements and Laydown Area
The pump station site layout is shown on Figure 2-1. Construction easements and laydown area at the pump
station site will use the pump station area as well as temporary construction easements that surround the
proposed site. A temporary and permanent access easement may be used for ingress/egress. Figure 2-2
illustrates the property limits, construction and access easements required for construction.
For the microtunneling, the area immediately west of the existing pump station will be used for a launch pit.
Figure 2-3 illustrates the laydown requirements for microtunneling construction. There is also a construction
laydown area around the receiving shaft at the west of the channel, within Caltrans right of way.
2.1.2 Offsite Staging Areas and Potential Pricing
Accessibility to construction staging sites within Newport Beach area is limited since the area is built-out. It is
expected that the contractor will require an offsite staging area that can be used for deliveries, storage, and
construction trailers. The potential offsite staging area alternatives are identified as listed below and on Figure
2-4.
Lower Castaways Park – On the other side of the bay, Castaway Park has areas that have been used for
construction staging for City projects. Soil shall not be stored at Lower Castaways Park.
OC San Treatment Plant No. 2 – OC San may offer an area at Plant No. 2 for the contractor staging and
Plant No. 2 will only be used for soil storage.
2.2 Construction Equipment
2.2.1 Shoring
Shoring will be necessary at several locations where excavations are deep, and space is limited. The pump
station site will require shoring for construction of the FMs and the pump station building. A receiving shaft on the
west side of Lower Newport Channel will require shoring and dewatering, once final connections are made the
shoring system will be removed in this area.
2.2.2 Dewatering
The depth of the groundwater table for the project area is at or near sea level. Several proposed excavations will
be below the groundwater table and need to be dewatered. The contractor should implement dewatering methods
to lower and maintain a groundwater level below the excavation bottom by about 5 feet.

Section 3 – Preliminary Construction Sequence Plan
The BBPS site is surrounded by private property to the north, west, and east and the PCH to the south. The
future odor control structure will be located at the existing BBPS site. The construction sequencing will need to
occur such that operation of the existing pump station is not interrupted until the new pump station is ready to
operate. As shown in Appendix A, the construction phasing of the Project includes six phases:
Phase 1 – Microtunneling
Phase 2 – Below Grade Pump Station Construction
Phase 3 – Pump Station MEP & Above Grade Construction
Phase 4 – Site Utilities for Pump Station Testing and Commissioning
Phase 5 – Pump Station Testing and Commissioning
Phase 6 – Existing Pump Station Demolition, Odor Control, and Site Utilities
The construction sequence will need to account for both the existing facility and limited space. During
construction sequence development, major construction milestones were identified as follows:
FM microtunneling and tie-ins completion (Phase 1)
Soil Improvements Phase A (Phase 1)
Pump station below grade completion (Phase 2)
Pump station above grade and pump station mechanical, electrical, and plumbing (MEP) (Phase 3)
Site utilities and electrical tie-ins, completion (Phase 4)
Pump station test and commissioning completion (Phase 5)
Existing pump station demolition (Phase 6)
Soil Improvements Phase B (Phase 6)
Permanent gravity approach pipe completion (Phase 6)
Odor control building completion (Phase 6)
Odor control commissioning (Phase 6)
This section outlines a proposed construction sequence for the given site constraints and includes the
aforementioned milestones. This section also provides details regarding certain construction aspects, including
temporary bypassing and pumping, temporary odor control, demolition of key facilities, and contingency plans.
3.1 Construction Sequence
The following narrative provides a description for one potential sequence to construct the BBPS.
3.1.1 Force Main Microtunneling and Tie-Ins
The pump station construction will first commence demolition, clearing and grubbing of the future pump station
site for the microtunneling work laydown and mobilization. The microtunneling launch pit will be located on the
southeast corner of the proposed pump station site, directly north of PCH and directly west of the existing BBPS
as shown in Appendix B. The available space onsite above grade is expected to be near fully occupied by the
microtunneling equipment as shown in Figure 2-3.
Once the shaft is constructed, the microtunneling operation will proceed. The microtunneling operation will be
controlled from an above grade station. The tunnelling will provide the casing for the FM pipes, placing segments
of 72-inch reinforced concrete pipe (RCP) in approximately 8 to 12-foot lengths for the 1,320-foot drive.
Construction Management Memo
Bay Bridge Pump Station Replacement
Project No. 5-67
3-2 March 2023
While the microtunneling operation is in progress from the east side of the bay, the receiving shaft on the west
side of Newport Beach Bay can be constructed. The receiving pit will be located just south of the PCH bus
transfer station/stop to the east of Dover Drive as shown in Appendix B.
The microtunneling operation will end when the microtunneling boring machine (MTBM) breaks through the
receiving shaft on the west side of the bay, completing the construction of the 72-inch RCP casing. The 24-inch
high-density polyethylene (HDPE) FMs will then be placed inside the pipeline, pressure tested, and grouted in
place. The FMs will then be tied-in to the existing NFM on the west side of the bay and connected to the existing
BBPS via temporary piping and operated with the existing BBPS flow until completion of the new BBPS.
Connecting the existing to the new FM’s will require a pump station shutdown and temporary pumped bypass.
The launching and receiving shafts on the east and west sides of the Bay will then be backfilled.
3.1.2 Soil Improvements Phase A
To prevent differential settlement of the buildings and facilities, soil improvements are proposed at the pump
station site. In either scenario, the site will be most accessible prior to initiation of the below grade pump station
work. Areas at the existing BBPS will not be accessible and soil improvements for that area will be completed
later in the project.
3.1.3 Pump Station Below Grade
After the contractor completes the first phase soil improvements (Phase A), below grade construction of the pump
station can commence. After shoring is placed, the shaft will be excavated to the depth required to pour the
tremie slab. Depending on the dewatering required, permit limitations, and contractor’s schedule the tremie slab
may be poured in the wet or in the dry after dewatering. Dewatering will likely continue after the tremie slab is
cured until the waterproof membrane and pump station bottom slab and walls are in place.
After the tremie slab is cured, the contractor can begin to place formwork and rebar for the bottom slab. If the
slab is poured as a monolithic pour directly against the shoring, no formwork will be needed.
After the bottom slab is cured the contractor will the place the rebar and formwork for the walls. Due to the
constrained site, it is likely that the whalers and struts used for the excavation will not be outside the footprint of
the pump station walls. Thus, the pump station walls will likely be poured in two phases. The first phase of the
walls will be poured up to the same level as the structural beams that provide lateral support in the finished pump
station. The beams will also be constructed in this phase. Once the walls and beams are cured and have
sufficient compressive strength, the whalers and struts can be removed, and the second phase of walls can be
poured up to grade. A picture showing the shoring concept is included below on Figure 3-1.
Construction Management Memo
Bay Bridge Pump Station Replacement
Project No. 5-67
3-3 March 2023
Figure 3-1- Shoring Concept for Removal of Whalers and Struts after Structural Beam Construction
Once the walls are cured to the design strength, the bridge crane will be installed. Finally, the pump station roof
deck falsework, formwork, and rebar, will be placed before pouring the concrete roof deck to grade.
3.1.4 Pump Station Above Grade and Pump Station MEP
During this phase of construction, concurrent work is expected, with the MEP work commencing in the below
grade structure while the above grade structure is constructed. The contractor will install the equipment pads and
equipment, including pumps, piping, and electrical equipment and conduits in the below grade structure while
building the above grade structure.
Electrical equipment in the electrical building will not be installed until completion of the above grade structure to
protect the equipment from the environment. After the electrical equipment is installed wire installation and
terminations can be completed and the equipment is ready for initial testing.
In addition to the pump station building, the generator building, including generator installation will be completed
during this phase.
All MEP installation, including heating, ventilation, and air conditioning (HVAC), is expected to be completed
during this time for the pump station and generator building.
Construction Management Memo
Bay Bridge Pump Station Replacement
Project No. 5-67
3-4 March 2023
3.1.5 Site Utilities and Electrical Tie-ins
It is unlikely significant sitework can be completed concurrently with structural construction of the pump station
building, construction of the generator building, or installation of major equipment. Therefore, it is anticipated that
site work will be completed after construction of the pump station structure.
The FMs are the deepest utility onsite and will need to be connected to the piping in the pump station. This
connection will be completed first. After that, the contractor is expected to complete the duct banks, odor control
subsurface connections to the FMs, and storm drains. Completion of electrical will be in stages, first a new
electrical connection will be made on the north side of PCH and will feed the new transformer. Once all new
buildings are complete, additional electrical ductbanks will be constructed to each building.
After the electrical utilities are completed, connection to Southern California Edison (SCE) can be completed.
3.1.6 Pump Station Test and Commissioning Phase 1 – Phase 4 (ORT, FAT, RAT, PAT)
Upon completion of all mechanical work, connection to SCE, electrical installation and loop testing, the project
can start commissioning which includes all phases of testing. After completion of the Performance Acceptance
Test (PAT), regular operation of the pump station will commence while the contractor is completing other work
onsite, as demolition of the existing BBPS and construction of the Odor Control Building is expected to continue
for several months after the PAT. The Reliability Acceptance Test (RAT) will be completed with a temporary
gravity approach pipe. The temporary gravity approach pipe is required because the final approach pipe conflicts
with the existing pump station which cannot be demolished until the pump station is tested.
3.1.7 Existing Pump Station Demolition
Once the new pumping facility is accepted by OC San, the existing pump station will be demolished.
3.1.8 Soil Improvements Phase B
After the existing pump station is demolished, the previous facility will be backfilled. Soil improvements at areas
of the pump station where is not accessible will be completed until the existing pump station is demolished.
3.1.9 Permanent Gravity Approach Pipe and Commissioning
After the existing pump station is demolished, the permanent gravity approach pipe can be installed. The pump
station can then be tested as a fully integrated system with a second PAT, ensuring all operating parameters
continue to work properly with the permanent approach pipe.
3.1.10 Odor Control Building
The odor control building construction can commence once the Phase B Soil Improvements are completed. The
building construction should start after the permanent gravity approach pipe is complete to provide additional time
for testing of the facility with the final configuration. The vapor phase odor control equipment consisting of a foul
air fan, duct, carbon scrubber, power, and control panel, and associated electrical and instrumentation are
required to be provided by the construction contractor. The construction contractor will also complete equipment
pads, plumbing, and connections for the liquid phase odor control tanks and equipment. Following completion of
the 5-67 contract, the liquid phase odor control equipment and tanks will be provided and tested by a third-party
chemical vendor using OC San’s master contract services (currently contracted with Hill Brothers Chemical
Company).
Construction Management Memo
Bay Bridge Pump Station Replacement
Project No. 5-67
3-5 March 2023
3.1.11 Odor Control Commissioning
Commissioning of the vapor phase odor control will be completed following construction. Liquid phase odor
control commissioning is not currently planned to be part of the construction contract and can be completed after
final completion of construction following installation by the third-party chemical vendor.
3.2 Demolition
The following sections provide additional details regarding facilities that will require demolition during BBPS
construction.
3.2.1 Pump Station
Once the new FMs and pump station are constructed and operational, the existing pump station demolition can
begin. The above grade portion of the existing pump station building will de-constructed and disposed of, while
much of the structure below grade will be abandoned in place. Only the upper portion of the structure will be
removed (approximately 7 feet below grade), and holes will be drilled into the bottom slab to allow for drainage
infiltration.
3.2.2 Force Main
The existing sewer FM will be abandoned in place where possible, flushed and filled with grout, or CLSM, and the
pipe ends capped or plugged. The FM abandonments will be done after the complete installation and activation of
the new FMs. Abandonment of sewers will also comply with OC San Specification 02278.
3.2.3 Diversion Structure
The existing diversion structure / valve vault on the west side of the channel will be abandoned in place. The
valve cover and all valves, piping, and appurtenances inside the valve vault will be removed or disposed of. Then,
the valve vault will be filled with traffic rated Styrofoam to 12-inch below grade, constructed 12-inch-thick
reinforced concrete slab on top, and flushed with vault walls.

Project No. 5-67
4-1 March 2023
Section 4 – Construction Quality Control Monitoring Plan
4.1 Vibration Monitoring
Considering that the project is located near residential developments, shoring methods, and piling installation may
cause vibrations that could affect nearby property owners and could potentially damage nearby structures.
Vibration monitoring should be performed during installation and extraction of driven sheet and or soldier piles.
Vibration monitoring equipment should be placed between the installation equipment and the nearest structures.
Equipment should be placed at varying distances to provide an indication of the reduction of vibration with
distance from the installation equipment. Peak particle velocity at the closest structure to the installation should be
kept below 0.5 inches per second.
A pre-construction assessment of the existing conditions of nearby structures should be performed, as well as a
post-construction assessment of the same structures to note any existing signs of distress before project
construction and after piling removal. Monitoring should be performed for all structures within about 300 feet of
the installation.
4.2 Noise Monitoring
Noise generated during the BBPS construction, including demolition, excavation, building construction, shoring
system installation, and nighttime construction work, will be limited and monitored.
Maximum noise levels and associated monitoring should be performed in compliance with the City of Newport
Beach code requirements and project specifications. According to the City of Newport Beach Municipal Code,
Chapter 10.28.040 for Construction Activity – Noise Regulations, construction work shall only be performed on
weekdays between 7:00 a.m. and 6:30 p.m. Additionally, OC San can impose additional restrictions where
necessary. Table 4-1 below lists the noise parameters from OC San General Requirements Specifications.
These hours will be reviewed with OC San and City during final design and adjusted if necessary.
Table 4-1 Noise Control Requirements per OC San Spec 001 General Requirements

Due to the commercial-residential properties around BBPS, noise mitigation measures should be implemented to
audit and control construction noise. Noise mitigation measures reported in the Mitigation Monitoring and
Reporting Program (MMRP) include:
Construction Management Memo
Bay Bridge Pump Station Replacement
Project No. 5-67
4-2 March 2023
Required noise attenuation devices for all construction equipment
Provide a Noise Disturbance Coordinator to respond to any local complaints
Haul routes to be designated avoiding noise sensitive areas (residences, schools, hospitals, etc.)
Avoid construction activities outside of the allowable hours specified by the City of Newport Beach
Implement a Noise Control Plan to include types, location, and duration of equipment used during project
construction, construction noise levels near sensitive areas within 1,000 feet of the project construction
area, and noise reduction measures to minimize noise levels at off-site sensitive uses.
It is possible that the Contractor may elect to install a sound wall if night work is anticipated. The most likely area
to install the sound wall is on West Coast Highway adjacent to the existing valve vault. Work in this area includes
the receiving shaft, sea wall, tie-ins to existing FM, and demolition of the existing valve vault.
