DISCUSSION:
On May 13, 2003, the City Council authorized the award of the Bayshores Water Main
Replacement contract to Cody Engineering, Inc., of Norwalk, California. The overhead
utilities within the Bay Shores tract were going to be placed underground (Assessment
District No. 70) in the fall of 2003. In an effort to coordinate with other City
improvements and in accordance with the Water Master Plan, staff recommended the
replacement of the deteriorating cast iron pipe section of the Bay Shores water system
servicing these homes before the undergrounding construction began. The existing
waterlines were constructed in the 1950's and relined in 1983. This project replaced
over 5,000 feet of waterline and the associated house services.
The contract has now been completed to the satisfaction of the Public Works
Department. A summary of the contract cost is as follows:
Original bid amount: $591,230.00
Actual amount of bid items constructed: $491,145.00
Total amount of change orders: $54,356.00
Final contract cost: $545,501.00

The decrease in the amount of actual bid items constructed over the original bid •
amount resulted from the reduction in contract work. The original design plans called
for the installation of a temporary bypass to maintain water services to the residents.
After the bypass was installed, the removal of the existing water main was to take place
prior to installation of the new water mains. The contractor was able to adjust the new
water m ain a lignment t o m aintain t he a xisting w ater m ains d uring c onstruction. T he
cost for the bypass and removal of the existing mains was deleted.
In addition, the Bayshores Community Association (Bayshores) is planning the
replacement oft he alleys upon completion of this project and the undergrounding of
utilities. Bayshores allowed a reduction in alley trench paving widths and thickness
resulting in $45,767.00 in asphalt savings. The final overall construction cost including
change orders was 7.7 percent below the original contract amount.
Funds for the project were expended from the following accounts:
Description Account No. Amount
Water Main Master Plan Improvement 7501- C5500074 $260,536.00
Pipeline Master Plan Replacement 7501- C5500578 $265,949.00
Assessment District No. 70 - Bayshores 7401- C5200483 $19,016.00
Total $545,501.00
All work was completed on December 19, 2003. The original completion date was
September 4, 2003. However, coordination between the undergrounding contractor
and Cody Engineering required a delay in the water main replacement project. In
addition, Cody Engineering was requested to complete the final street paving within the
project area though the water main installation was completed in early November.
$19,016 was charged to the Assessment District for completion of the undergrounding
districts portion of the joint street paving efforts.
Environmental Review:
The project was determined to be exempt from the California Environmental Quality Act
(CEQA) pursuant to Section 15302 of the CEQA Implementing Guidelines at the time
the project was authorized by the City Council. This exemption covers the maintenance
and alteration of existing public facilities with negligible expansion of the facilities in
areas that are not environmentally sensitive.
