BACKGROUND INFORMATION: The contract was awarded to C. Overaa & Company, of Richmond, on October 20, 2010, in the amount of $22,837,000. The contract has been completed in substantial conformance with the plans and specifications approved by City Council. This project consisted of the construction of a raw water pump station in Woodbridge; approximately 500 feet of 30 -inch raw water transmission pipe, an operations building, chemical building, sedimentation structure, 3 -million -gallon treated water storage tank, and treated water high service pump station at the treatment facility's 4.2 -acre site adjacent to Lodi Lake; approximately 4,000 feet of 36 -inch treated water transmission pipe and installation of chlorine and chemical injection systems at approximately 25 well sites throughout the City; traffic signals and intersection work at Mills Avenue and Turner Road; and all other site and utility improvements associated with the project. The contract completion date was March 1, 2013. The final contract price was $25,515,343. The difference between the contract amount and the final contract price is due to 15 change orders. A copy of each of the executed change order forms is attached for reference. Complete supporting documents are on file at the Public Works Department. Total change orders were $2,678,343 or 12% of the original contract. The project was substantially completed on November 1, 2012 and received the permit to operate from the Regional Water Quality Control Board on November 26, 2012. 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: Increase in costs for operating the facilities will be approximately $1.7 million the first year and approximately $1.4 million each year thereafter. FUNDING AVAILABLE: This project was funded by the Water Fund (181011). _4L F.

This work included: traffic control, saw cutting of the asphalt and concrete, off -haul of the removed asphalt and concrete and repaving the roadways impacted by the railroad work.
