6.2.C. - Page 1 RE PO RT To the Honorable Mayor and City Council From the Cit Mana er January 14, 2013 SUBJECT Final Acceptance — Sanitary Sewer Pump Station No. 14 Improvements Project RECOMMENDATION Accept, by motion, the Sanitary Sewer Pump Station No. 14 Improvements and authorize the release of bonds and retention according to city procedures. BACKGROUND On March 5, 2012, Council awarded the construction contract for the rehabilitation of Sanitary Sewer Pump Station No. 14 to Casey Construction, Inc. Rehabilitation of this pump station improved pumping efficiency, ease of operation and the safety of the facility. A permanent emergency standby engine generator replaced an outdated engine generator to ensure continuous service of the pump station in the event of power failure, larger horsepower pumps and an up to date control system were installed. Construction started in May 2012 and was substantially completed in October 2012. Final walkthrough was conducted with city's maintenance staff, inspector, engineers and contractor. Final completion was achieved in December 2012. The project schedule was extended due to the delay in obtaining temporary and permanent electrical service from PG&E as well as the delivery of motor control center. This acceptance was delayed pending the contractor's submission of the final progress payment for approval received on November 2012. ANALYSIS The contract was awarded for a base bid of $369,918. The project was successfully completed in accordance with the plans and specifications. Change orders were issued totaling $16,750.35. The final contract amount is $386,668.35 which is 4.5% more than the initially awarded contract amount. Change orders resulted from additional work required to remove and relocate existing buried electrical conduit exposed during deconstruction that were not shown on the record drawings, salvaging of existing generator for the City, raising the wet well elevation, installation of shut-off valves for the generator block heater, and for additional grading and paving work to the area surrounding the pump station and valve vault. ALTERNATIVES Council may choose not to accept the project and/or authorize the release of bonds and retention which would be contrary to the terms of the contract, prior Council action, and the public contracting code.
