AGENDA TITLE: Acceptance of Improvements Under Well 4R Water Storage Tank and Pump
Station, 1215 Thurman Street, Contract
MEETING DATE: November 5, 1997
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council accept the improvements under the "Well 4R Water
Storage Tank and Pump Station, 1215 Thurman Street" contract, and
direct the Public Works Director to file a Notice of Completion with the
County Recorder's office.
BACKGROUND INFORMATION: The contract was awarded to Conco West, Inc., of Manteca on
April 23, 1996 in the amount of $1,222,300.00. The contract has
been completed in substantial conformance with the plans and
specifications approved by the City Council.
The contract completion date was May 22, 1997, and the actual completion date was October 24, 1997.
The difference in the completion dates is due to delays in delivery of City -furnished equipment that was
integral to the completion of the project as a whole. The final contract price was $1,372,571.13. The
difference between the contract amount and the final contract price is outlined in the attached change
order summary.
The bulk of the cost of this project is funded by a low-interest loan through the Department of Water
Resources. Fifty percent of the actual costs of this project will be reimbursed through the DBCP
settlement.
