AGENDA TITLE: Accept Improvements Under Contract for Lodi Lake Storm Drain Outfall
Improvement Project
MEETING DATE: August 5, 2015
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Accept improvements under contract for Lodi Lake Storm Drain
Outfall Improvement Project
BACKGROUND INFORMATION: The project was awarded to Diede Construction Inc., of
Woodbridge, on December 17, 2014, in the amount of $63,120.
The contract has been completed in substantial conformance with
the plans and specifications approved by City Council.
This project consists of replacing the existing storm drain outfall pipe and constructing a new concrete
outfall structure for the existing Lodi Lake storm drain pump station and an existing 48 -inch slide gate
was purchased by the City and installed by the contractor. The work had to be completed during the
period when Lodi Lake is drained for Woodbridge Irrigation District maintenance.
The contract was completed within the contract schedule. The original contract amount was $63,120.00.
The final contract price was $88,963.03. The difference between the contract amount and the final
contract price is due to Change Order #1 which includes additional removal of unsuitable soil material
and replacing it with class 2 aggregate base and increases in contract unit quantities of AB and Rip Rap
materials totaling $25,843.03.
Following acceptance by the City Council, as required by law, the City Engineer will file a Notice of
Completion with the County Recorder's office. The notice serves to notify vendors and subcontractors
that the project is complete and begins their 30 -day period to file a stop notice requiring the City to
withhold payments from the prime contractor in the event of a payment dispute.
FISCAL IMPACT: The new pipe and outfall will decrease the on-going maintenance of the
Lodi Lake storm drain system.
FUNDING AVAILABLE: This project is funded by Lodi Lake Storm Drain Pipe (53199000.77020)
$40,000 and Wastewater Capital Fund (53199000.77020) $60,000
