BACKGROUND On January 15, 2013, City Council awarded the construction contract to Caggiano General Engineering in the amount of $498,603.30. The City Council also authorized the Director of Community Development to approve and execute required contract change orders to address unanticipated project conditions for a not-to-exceed amount of$74,790. DISCUSSION This project is part of the City's on-going maintenance program to replace aging underground water facilities that have a potential for breakage and leaks. This project was high on the City's priority list due to the poor condition of the existing 12" cast iron water main installed in the mid-1950s, and the timing of the upcoming resurfacing project along Vineyard Avenue. This project upgraded the inlet yard piping in the Vineyard Avenue pump station which improves water quality in the area by providing better blending of water sources. Construction change orders for the project resulted in a net increase of $13,318.91, which is approximately 2.7% of the original contract amount. Change orders included: the removing an existing valve not shown on the plans; removing thicker AC pavement sections than anticipated; correcting existing deficiencies at four water meters; installing an additional 8" water valve; and removing and replacing approximately 50 feet of misaligned 12" cast iron water main for the fusible 8" PVC installation. Total project expenditures are $523,175 (see Attachment 1, for Funding and Expenditure Summary) leaving an unspent balance of $66,180.29 remaining, which staff recommends be returned to the Water Replacement Fund balance. All of the contract work has been completed to the City's satisfaction. This project is now complete and ready for City Council acceptance.
