Staff is requesting that the City Council  authorize and execute a Contract Amendment for Professional Services with HDR Engineering to provide additional engineering services for W.O. 12-45 3 MG Staples Reservoir Liner. The purpose of this project is to provide a liner in the Staples 3 MG (Million Gallon) reservoir with the intent to reduce/eliminate water leakage and extend the life of the tank.

After the liner manufacturer representative performed a site visit in November, he required the contractor to perform extra surfacing preparation which was not planned. He required the extra work to back the warranty. The extra work has extended the active construction period requiring us to extend the engineering contract with HDR to have a full time NACE certified inspector on the surface preparation, liner application, and testing. This is the most critical time for the inspector to be on site.

The Council may:

• Authorize Contract Amendment No. 2 with HDR Engineering in the amount of $5,300; or
• Do not authorize the Contract Amendment No. 2.

Funding for this project is from water revenues and is included in the FY13 budget. If approved, the Professional Services Contract with HDR will total $112,500.00.

Staff recommends that City Council authorize Contract Amendment No. 2 with HDR Engineering in the amount of $5,300.
