CITY OF SAN LUIS O B I S P O
FROM: Jay D. Walter, Director of Public Works ,70W
Prepared by: Dan Van Beveren, Senior Civil Engineer
SUBJECT: RAW WATER BYPASS, SPECIFICATION NO. 90802
CAO RECOMMENDATION:
1. Award a contract to Vinciguerra Construction in the amount of$318,416 for the Raw Water
Bypass Project, Specification No. 90802 and authorize the Mayor to execute the agreement.
2. Approve the fund transfer amounts of$418,416 from the Water Treatment Plant Major
Equipment Maintenance Account to the Raw Water Bypass Project.Account.
DISCUSSION
The City's raw waterline delivers untreated water from the Salinas Reservoir to the Water
Treatment Plant on Stenner Creek Road. A portion of the raw water pipeline approximately one
mile north of the Water Treatment Plant is in poor condition and requires frequent maintenance.
The Raw Water Bypass project involves the installation of approximately 1000 feet of new
waterline which will bypass the existing,substandard piping.
On August 19, 2008, the City Council authorized the invitation for bids for the Raw Water Bypass
project. The City received ten bids which were opened on September 25, 2008. The lowest bid
was received from Vinciguerra Construction in the amount of$318,416.
Each of the ten bids received for this project were greater than the Engineer's Estimate of$300,000.
However, staff does not believe that there is any advantage to rebidding the project and is
recommending that the construction contract be awarded to Vinciguerra Construction in the amount
of$318,416.
FISCAL IMPACT
The project, as approved by Council, contained an engineer's estimate of $300,000 for the
construction contract, $30,000 for contingencies, $60,000 for construction management and
$10,000 for testing and other miscellaneous costs for a total construction budget of $400,000.
With the lowest bid amount of $318,416, an additional $18,416 will be needed to fund the
construction contract. We believe the funding for the other items is adequate. The total project
budget as proposed is shown in the table below.
