Total contract cost
$1,665,150.00
212,495.30
$1,877,645.30
A total of 33 change orders were issued to complete the project. The change orders covered a
wide range of items from project completion date extensions to design and field changes. In
addition, several significant change orders were initiated by the City to minimize impacts to the
community. The first of these change orders was to leave the costly shoring in place. The original
plan had allowed for the removal of the sheet pile shoring system. However, based on a significant
number of complaints from the neighboring residents, it was decided to not disrupt the community a
second time by removing the sheet pile shoring system. Along the same lines of thinking, Little
Balboa Island is currently in the process of designing the undergrounding of the power, phone and
cable television utility lines. In an effort to prepare for this, the City Council approved a budget
amendment that funded the undergrounding within the project area. These funds will be
reimbursed to the City through a future assessment district. The following is a summary of the
change orders:

Removal of two palm trees on the north side of Park Avenue at the wet well site was deleted. The transplanting
of two palm trees from the north side of Park Avenue at the wet well site to the median in Park Avenue at a location
as directed by the City was added. The removal of the palm trees was required to construct the project and was
included in the project construction plans. The residents of Little Balboa Island, through the public review process,
requested that the two mature palm trees be transplanted to the median planter in Park Avenue near the bridge,
rather than planting two smaller trees at that location.
Change Order No. 4: Weather Delay & Holiday Time Extension
On December 11, 1997, a one day time extension was granted due to high winds preventing sheet pile threading.
A one day time extension for Advanco Constructors to work half -day on Christmas Eve and not to work on
December 26, 1997 was granted to promote community relations. In addition, another one day time extension to
promote community relations for Advanco to work half -day on New Year's Eve and not to work on January 2, 1998
was also granted.
Change Order No. 5: Parking Notice Sign on Little Balboa Island
A parking notice sign in the median of Park Avenue near the entrance to Little Balboa Island was installed. The
parking notice sign was required to inform residents and visitors that between January 5, 1998 and March I, 1998
parking permits will be required for public parking on Little Balboa Island. The sign provides public information
about the parking restrictions and how residents and visitors may obtain parking permits.
Change Order No. 6: Installation of Dezurik Eccentric Plug Valves
Two 8 -inch Clow eccentric plug valves in the force main valve vault, three 8 -inch Clow eccentric plug valves and
one 4 -inch Clow eccentric plug valve in the pump station valve vault were deleted.
Installation of two 8 -inch Dezurik eccentric plug valves in the force main valve vault, three 8 -inch Dezurik eccentric
plug valves and one 4-inch Dezurik eccentric plug valve in the pump station valve vault was performed. Advanco
Constructors, Inc. submitted Clow plug valves as "equal' equipment. The City of Newport Beach has standardized
its plug valves throughout the City with Dezurik brand valves, and for maintenance purposes, requires that the
valves on the Section 5 Sewage Pump Station be compatible with the existing valves in the system. A gear operator
and 2 -inch nut was added to the 4 -inch valve to allow operation of the valve from the street with a key.
Change Order No. 7: Temporary Removal of Water Line at Park Avenue & Jade Avenue
Advanco Constructors requested to install at no cost one 6 -inch and one 4 -inch water line valve to be provided by
the City at no cost. Advanco temporarily removed portions of the water lines at Park Avenue and Jade Avenue

make, model, and size supplied by the City no later than March 16, 1998. Advanco restored the water line to its
original location prior to completion of the project using C -900, Class 200 PVC water pipe.
Change Order No. 8: Revisions to Electrical Control Panel
The City Utilities Department reviewed the specification for the electrical control panel and deleted various
equipment items in the panel.
Change Order No. 9: Weather Delay - Section 5 Pump Station
The project completion date was adjusted for the weather - related loss of working days which occurred on January
29, 1998, and February 3, 6, and 9, 1998. The project duration was based on calendar days, so the project
completion date was adjusted to include additional calendar days, as appropriate.
Change Order No. 10: Weather Delay -Jade Avenue Construction
The project completion date was adjusted for the weather - related loss of working days which occurred on January
29, 1998, and February 3, and 6, 1998. The project duration was based on calendar days, so the project completion
date was adjusted to include additional calendar days, as appropriate.
Change Order No. 11: Bonus For Early Completion of Jade Avenue -Phase II Construction
The bonus for completion of the Jade Avenue portion of the project on February 16, 1998, seven days prior to the
scheduled completion date of February 23, 1998. The bonus totaled $14,000 at the rate of $2,000 per day for the
bonus.
Change Order No. 12: Loss of Production Time from Encountering Unknown Underground Utilities
On February 5, 1998 Advanco Constructors uncovered two previously unknown underground pipes in the vicinity
of manhole no. t at Park Avenue and Jade Avenue. Trenching operations were shut down for one hour while the
pipes were identified as abandoned and could be removed. The pipes were not identified on the construction plans.
Change Order No. 13: Install a Sewer Service Connection from the Apartment at 127 E. Bay Front and
Modify Sewer Manhole No. 6
A sewer service connection was installed to improve a previously constructed service for the apartments at 127 E.
Bay Front. The original sewer service for the apartments connected directly to the main drain line for the house
with a 90- degree elbow, creating a potential for plugging of the service line. Connection of the sewer service was
performed on a time and materials basis.

Utility conflicts required the construction of a 48 -inch diameter manhole at manhole no. 6 at the north end of East
Alley. The plans originally called for a 60 -inch diameter manhole to be installed. The contractor provided to the
City a credit for the cost difference.
Change Order No. 14: Weather Delay and Work on President's Day Holiday
One working day time extension was requested and granted due to a weather - related delay on February 19, 1998.
One working day time deletion to the project completion date was approved for allowing the Contractor to work
on President's Day, February 16, 1998. President's Day is a holiday recognized by the City, but not by the
Advanco Constructors or the labor unions.
Change Order No. 15: Sheet Piling to Remain in Place at Pump Station
The City directed Advanco Constructors to cut off the sheet piling at the pump station three feet below street grade
and leave the sheet piling in place at the site. A time extension of three working days was added to the project
completion date.
Change Order No. 16: Installation of Parking Notice Sign on Little Balboa Island
At the request of the Little Balboa Island Property Owner's Association the temporary permit parking notice sign
in the median of Park Avenue near the entrance to Little Balboa Island was replaced to extend the effective date
of the permit parking policy until further notice. The parking notice sign was required to inform residents and
visitors that parking permits are required for public parking on Little Balboa Island. The sign provided public
information about the parking restrictions and how residents and visitors may obtain parking permits.
Change Order No. 17: Install Electrical, Telephone, and Cable TV Conduit in East Alley and Park Avenue
The proposed Rule 20 utility undergrounding project scheduled for 1999 includes relocating all of the above ground
electrical, telephone, and cable tv transmission lines and poles on Little Balboa Island underground. The City
directed Advanco Constructors to install buried conduit for the overhead utilities in areas of Park Avenue and East
Alley under construction for the Section 5 Pump Station project. Installation of the underground conduits prior to
repaving for the Section 5 project will eliminate the future need to remove and replace portions of the new concrete
pavement reduce and disruption to the residents.
Change Order No. 18: Weather Delay/Damage from Seawater Intrusion
9
The project completion date was adjusted due to weather - related loss of work days and damage caused by flooding
from relatively high tides on March 25 and 30, 1998 and April I, 1998. The high tides caused seawater to enter
the excavation on March 30, 1998 and flooding from stormwater runoff from rainfall on April I, 1998. This .
change order included time and materials costs to clean up damage from flooding.

Change Order No. 19: Install Rule 20 Underground Utility Conduits and Structures
The proposed Rule 20 utility undergrounding project scheduled for 1999 includes relocating all of the above ground
electrical, telephone, and cable tv transmission lines and poles on Little Balboa Island underground. The City
directed Advarco Constructors to install buried conduit for the overhead utilities in the areas of Park Avenue, Jade
Avenue and South Alley under construction for the Section 5 Pump Station project. Installation of the underground
conduits prior to repaving for the Section 5 project will eliminate the future need to remove and replace portions
of the new concrete pavement and reduce disruption to the residents. This change order includes an extension of
five working days and two calendar days to the project completion date.
Change Order No. 20: Install 1" conduit from Section 5 Control Panel to Sea Wall for Tidal Gauge on
Public Dock
The City requested that Advanco Constructors install a one -inch PVC coated, galvanized steel conduit from the
Section 5 control panel to the end of Park Avenue and through the seawall. The conduit will connect a sonic meter
to be mounted at the public dock with instrumentation and communication equipment in the Section 5 control panel.
The City will be able to continuously monitor tide levels via the City SCADA system.
• Change Order No. 21: Modify Orientation of Plug Valve and Fabricate Valve Handle, Revise Water
Service Connection and Eliminate Backflow Preventer
Limited space in the pump station valve vault required that the center plug valve be rotated on its side and a
specially shaped valve handle be fabricated to clear adjacent piping and valves and provide a full field of travel for
the valve operating nut.
The use of soft solder connections on work done previously by Advanco Constructors on the two -inch water service
was rejected. A one -inch service was installed at another location on the water main to replace the abandoned 2-
inch service. Credit for labor was provided to the City for not installing the backflow preventer. The backflow
preventer was delivered to the City operations department.
Change Order No. 22: Modifications to Force Main and Valve Vault in South Alley, Delays from existing
Sea Wall Tieback and Storm Drain Catch Basin, and Credit for not Removing fill
concrete
Revisions to the force main and valve vault in South Alley included raising the force main grade, decreasing the
valve vault depth, increasing the vault size, and changes to fittings, pipe stands, etc. The air /vacuum valves were
deleted.
Additional labor and materials were required by Advanco Constructors due to the location of the sea wall tieback
and the storm drain catch basin. The plans showed these obstacles to be far enough away from the new force main
ialignment to require minimal effort to protect them during construction. The sea wall tieback was uncovered and

determined to be located between the two force mains. The corner of the catch basin was located above one of the
force mains.
A credit to the City was provided for not having to remove fill concrete shown on the plans at the old force main
valve vault under the sidewalk at the sea wall.
Change Order No. 23. Modifications to Sewage Pumps Motor Size, Motor Starters, and Power Cables
The motor size on the two large sewage pumps was increased from 15 hp to 25 hp in order to provide future
flexibility in operation and to allow for changes to the pumping system which may require additional power for the
pumps. Increasing the motor size required that the motor starters and power cables be upgraded to match the motor
horsepower.
Due to problems with casting the two large pumps which resulted in poor operating efficiencies, Advanco and their
pump supplier agreed to provide at no additional cost two cast -iron pumps on an interim basis until the permanent,
stainless steel pumps can be remanufactured, delivered, and installed.
Change Order No. 24: Remove and Replace Concrete Pavement at Gas Line Relocations, and Credit for
Damage to Beaches Caused by Dewatering System
The City requested that Advanco Constructors remove and replace concrete and temporary asphalt in East Alley
and South Alley at areas where the gas line was relocated in December, 1997 in support of the Section 5 project.
The work was done in coordination with other pavement removal and replacement work on the project.
The discharge from the contractor's dewatering system caused erosion of the beaches at the east end of Park
Avenue and the south end Jade Avenue. Erosion of the beach sand caused material to be deposited under public
and private docks. Material was dredged from under docks and returned to the beach areas. A credit was provided
to the City for a portion of the cost of the dredging operation.
Change Order No. 25: Extra Work to Demolish and Remove Valve Vault and Abandoned Force Main,
Construct Access Hole in Roof of Existing Pump Station
Advanco Constructors excavated an old, abandoned force main valve vault and force main in South Alley.
Demolition of the force main and valve vault was required in order to proceed with construction of the new force
main. In addition, the gas line to be relocated in the east end of South Alley was not relocated as shown on the
plans and interfered with construction of the new force main.
\_J
The City requested that Advanco Constructors core drill a 30 -inch diameter hole in the roof of the old pump station
above the pumps in order to provide interim access to the equipment in the pump station following installation of .
the 18 -inch force main casing pipe through the pump station walls.

Change Order No. 26: Reduce Diameter of South Alley Manholes, Utility Support for Utility Obstructions,
and Weather Delay Time Extension
Advanco Constructors requested that the 60 -inch diameter manholes in South Alley be reduced to 48 -inch diameter
in order to avoid utility conflicts during construction. All revised manholes are less than twelve feet deep. City
standards require manholes twelve feet or deeper to be 60 -inch diameter. Credit was given to the City for the
reduced manhole size.
A power pole approximately two feet from the gravity sewer alignment in South Alley and a gas service line for
106 Jade Avenue were not shown on the plans. Support from Southern California Edison to hold the power pole
during construction of the gravity sewer and temporary relocation of the gas service was required by Advanco
Constructors.
Time extensions due to rain on May 5, 1998 and May 13, 1998 were granted.
Change Order No. 27: Install Power Cables from Meter to Control Panel, Modify South Alley Valve Vault,
Delete Landscape Restoration
. The plans show that Southern California Edison (SCE) was to pull the power cables through the conduit from the
meter pedestal to the control panel in Park Avenue. SCE normally does not install cable on the customer side of
the meter and refused to do so on this project. Advanco Constructors installed the power cable on a time and
materials basis.
The top of the force main valve vault in South Alley was constructed too low based on the approximate finish
elevation shown on the plans. One of the vault rings was removed and replaced with a taller section that sloped in
the direction of the finished alley grade to match the alley flow line and garage approach at 1810 S. Bay Front.
The City paid for a new vault section. Advanco Constructors paid for all labor to remove and replace the vault
section.
The landscape restoration work in the median in Park Avenue was deleted from the contract and a credit provided
to the City. Landscape restoration work will be performed by the City landscaping contractor as part of the City
landscape improvement plan for the area.
Change Order No. 28: Modify Portable Generator and Install Ladder -Up Safety Posts
The City requested that the I00kVA portable generator supplied with the project be modified to allow its use at the
Cameo Shores Pump Station (200 amp) as well as at the Section 5 Pump Station (100 amp). Modifications include
installing a 100 amp 3 -pole circuit breaker and 200 amp receptacle. Forty feet of 200 amp power cord was also
supplied. A forty-foot 100 amp cord was supplied by the City and credit for it given to the City by Advanco.
• Installation of two "Ladder -Up" safety poles manufactured by Bilco was added at the suggestion of Advance,
Constructors. The safety poles were installed at the pump station manway hatch and in the South Alley valve vault.

Revisions to plan sheets 3, 13, 16, 20, and 28 made on December 29, 1997 included enlarging the stainless steel
access hatch, installing 1 -inch vent piping between each discharge pipe in the valve vault and the pump station, and
reconfiguration of the 4 -inch bypass piping. Revisions to the plans were made to provide better pump operation
and access to the bypass piping. A one day time extension for construction of the vent piping was included in the
change order.
Change Order No. 30: Bonus for Early Completion of Project
Bonus earned for reaching substantial completion of project forty-five (45) days prior to the scheduled completion
date. In accordance with Special Provision 1 -5, the bonus for each calendar day completed in advance of the
scheduled completion date is $2,000 per day. The project completion date was August 8, 1998 after adjustments
for weather delays and extra work added during the course of construction. Advanco Constructors substantially
completed the project on June 24, 1998. Substantial completion of the project included installation of all
underground piping, testing and placing the new pump station in operation, demolishing the old pump station,
replacing pavement, and opening streets and alleys to public use.
Change Order No. 31: Abandon Two-Inch Fire Hydrant Service Line in South Alley and Relocate Street
Light Junction Box
The plans show the two -inch fire hydrant at the old pump station site in South Alley to be removed with a
connection to the water main located in a section of water main to be abandoned. The hydrant connection was
actually located outside area of the abandoned water line and required additional effort to locate and abandon the
water line, and remove and replace alley concrete. The contractor potholed the fire hydrant and the connection to
the water main and abandoned the service line at the water main. Work was performed on a time and materials
basis.
The street light junction box was constructed in the center of the driveway to I I I E. Bayfront at the direction of
the SCE inspector. Future construction of a street light at that location would have blocked driveway access for
the residence, so thejunction box was relocated to the former fire hydrant location next to the existing power pole.
Work was performed on a time and materials basis.
Change Order No. 32: Install Seals in Pump Station Hatches, Install Sewer Drop Pipe and Screen in Pump
Station
The City directed Advanco Constructors to install strips of neoprene rubber to the underside of the hatches at the
pump station. The rubber strips are being installed to seal against the inside hatch frame lip. Work was performed
on a time and materials basis.

The City directed Advanco Constructors to fabricate and install in the pump station sump a PVC drop structure
consisting of a 12 -inch tee, pipe, and 45- degree elbow. The tee was bolted to the pump station wall at the end of
the influent sewer line. Sewer influent flow is directed downward to a point submerged below the normal low water
surface elevation in the sump. The basket strainer was removed and two stainless steel screens were bolted to the
lower part of the basket strainer frame. Work was performed on a time and materials basis.
The City directed Advanco Constructors to apply silicone caulk and Rap-0 Seal sealant to the pump station
hatches.
The City directed Advanco Constructors to modify the wet well exhaust vent stack in the Park Avenue median by
cutting it off at grade, removing the solvent weld fitting, installing reducer bushings to reduce the outlet diameter
from 12 inches to 6 inches, installing a 6 -inch PVC 90- degree elbow, and connecting to a drum filter of activated
carbon provided by the City.
Change Order No. 33: Modify Sewer Drop Pipe in Pump Station Wet Well, Relocate Low -Level Float
Switch Mounting Bracket in Wet Well, Electrical Sub - Contractor Extra Work
Claim Resolution
• The City directed Advanco Constructors to further modify the sewer drop pipe in the pump station wet well. The
stainless steel screen was removed and the sewer pipe discharge was extended to the wet well sump floor and a 45-
degree elbow was attached to direct influent sewer flows to the bottom of the wet well sump. Work was performed
on a time and materials basis.
The City directed Advanco Constructors to relocate the existing stainless steel low -level float switch bracket on
the wall of the pump station wet well to improve operation of the pump station. Work was performed on a time
and materials basis.
The electrical sub - contractor, Beard Electric, submitted a claim for extra work to place red -oxide concrete
encasement in single and dual conduit trenches in Park Avenue. Contractor claimed a discrepancy between plans
and standard SCE specifications. The City does not recognize the validity of the claim, but to avoid further
administrative costs agreed to pay fifty percent of the claim amount.
Table 1 is a summary of the change orders to date required for the completion of the pump station project.

Construction areas were fenced and barricaded throughout the project in order to keep residents and
visitors safely out of harms way. Advanco Constructors, Inc., the Contractor, was responsible for site
safety and placed a very high importance on site safety per OSHA requirements.
No accidents were reported at the project site throughout the duration of the project. An accident at the
staging area was reported to have occurred on January 7, 1998 when a crane tipped over while unloading
a clamshell bucket from a flatbed trailer. Injuries to the operator consisted of a broken ankle. The
accident was attributed to operator error with too much boom for the load being lifted. The operator,
Mr. Steve Guidas, was authorized to operate this equipment.

COMMUNITY RELATIONS
Residents were kept fully informed of the project progress and schedule through various means. The
construction schedule was posted on the dewatering tank at the end of Park Avenue and provided an
overview of the construction schedule. The project team worked closely with the Little Balboa Island
Property Owner's Association to distribute information to residents through the Property Owner's
Association monthly newsletter. The onsite construction representative fielded questions at the jobsite
and by telephone at the construction management trailer. In spite of the general disruption and the
parking and traffic inconvenience, residents have expressed their appreciation for the work that Advanco
Constructors has done to maintain the project site in a clean and orderly manner, and the respect and
demeanor towards the residents displayed by the construction workers.
