AGENDA TITLE: Accept Improvements Under Contract for Well 6R Granular Activated Carbon
Treatment System Project
MEETING DATE: November 6, 2013
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Accept improvements under contract for Well 6R Granular Activated
Carbon Treatment System Project.
BACKGROUND INFORMATION: The contract was awarded to Vinciguerra Construction, of Jackson, in
the amount of $596,810, on August 15, 2012. The contract has been
completed in substantial conformance with the plans and
specifications approved by City Council.
This project consisted of furnishing and installing a granular activated carbon (GAC) treatment system for
Well 6R.
The contract completion date was October 8, 2013. The final contract price was $630,306.47. The
difference between the original contract amount and final contract amount is due to an increase in the units
of concrete placed ($8;000.00) and Change Orders No. 1 ($8,610.62) and No. 2 ($16,885.85) which are
related to additional wastewater line demolition and replacement work, primarily on Washington Street, and
some additional aggregate base on site.
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: Annual operation and maintenance costs for the water utility will increase
as a result of this project. Operation costs are reimbursed through the
City's DBCP settlement
FUNDING AVAILABLE: This project was funded by Water Capital Outlay Fund (181048).
