BACKGROUND:

Previous Board Action

1.

Adopted Resolution No. 069601 on July 22, 2008, which adopted revised plans and specifications, determined prevailing wage scales and awarded and authorized execution of a contract with Stoloski & Gonzales, Inc. for the above-mentioned project.

   

2.

Adopted Resolution No. 064550 on June 19, 2001, which authorizes the Director of Public Works to execute agreements with utility agencies for utility type work costing less than $50,000 proposed to be done in conjunction with road projects.

 

HISTORY

After execution of a contract with Stoloski & Gonzales, Inc. (“Contractor”) for the MidCoast Drainage Improvement Project, utility conflicts between the proposed storm drainage improvements and Montara Water & Sanitary District (District) water mains were discovered.

 

The Contractor has provided a cost proposal in the amount of $25,900 for performing the work to relocate the District water mains; and the District has agreed to the contractor’s proposal and has executed a cost-sharing agreement with the County.

 

DISCUSSION:

In order to begin construction, District water mains in conflict with the proposed storm drainage improvements must be relocated. The County’s Contractor will perform the work. We will compensate the Contractor and then be reimbursed by the District for the actual cost to perform the relocation work.

 

A cost-sharing agreement has been executed between the District and the County, but an increase in the contract amount must be approved. As such, staff has determined that a total increase in the amount of $35,000 will cover both the cost of the work to relocate the District water mains, as well as any additional work required due to design changes from the conflicts for the proposed storm drainage improvements.

 

A resolution has been approved as to form by County Counsel.

 

FISCAL IMPACT:

The relocation work cost proposal from the Contractor is for a maximum amount of $25,900 and is proposed to be reimbursed to the County by the District upon completion and approval of the relocation work. The actual reimbursable costs for the relocation work will be based on the per unit prices submitted by the Contractor in its cost proposal; and any costs above the cost proposal amounts will be paid for through the County Road Fund.

 

Funds have been appropriated in the Road Fund to finance this work.

 

There is no impact to the General Fund.
