ENG ACCEPTANCE OF BIDS AND AWARD OF CONTRACT FOR THE CONSTRUCTION OF MAERKLE PUMP STATION UPGRADE PROJECT NO. 5009-B DEPT. HEAD "j^-f^T CITY ATTY. ^ CITY MGR. (JA-*"" RECOMMENDED ACTION: Adopt Resolution No. 1381 Maerkle Pump Station Upgrade Project No. 5009-B. ITEM EXPLANATION: accepting bids and awarding contract for the construction of Maerkle Dam reservoir and its auxiliary facilities are located in the northeast part of the City and are a critical part of the potable water supply system for the City. Maerkle Dam reservoir (formerly known as Squires Dam reservoir) was initially constructed in 1963. In the late 1980's and early 1990's, various auxiliary facilities were added, including a 10 million gallon concrete storage tank, transmission pipelines, a 33.5 million gallons per day pump station, and chlorination facilities. In May 2007, staff commissioned a study to evaluate all the facilities at Maerkle Dam reservoir. The study report identified 20 priority items that need replacement to meet current code requirements for health and safety and to maintain reliability of this water supply source. These items were presented to the Board via Agenda Bill No. 645 on December 11, 2007, and are summarized in Exhibit 2. Additional agenda bills will be presented to the Board for consideration when the plans and specifications are completed and appropriate implementation schedule windows are identified. The Maerkle Pump Station Upgrade Project involves high priority items 2 and 19. Item 2 replaces and upgrades electrical components at the pump station, such as variable frequency drives, switches, soft starters, controls, relays, lights, etc. The existing pumps were constructed in 1992. The existing units are requiring increased attention to remain operable and have reached the end of their useful life. To minimize the risk of pump failure and inability to deliver water, the existing electrical components need to be replaced. Item 19 provides for improvements at the two existing gates to the site to provide for a more secure site. On July 28, 2009, the Board adopted Resolution No. 1366 approving plans and authorizing to advertise for bids. On September 17, 2009, seven (7) bids were received. The bids are summarized in Table 1. The lowest responsive bidder, Neal Electric Corporation dba: Nealectric, Inc. submitted a bid in the amount of $188,850. Staff has completed the review of all contract documents and has determined that they are in order. Therefore, staff recommends that Neal Electric Corporation dba: Nealectric, Inc. be awarded the contract. ENVIRONMENTAL IMPACT: This project is a Class 2 categorical exemption (replacement or reconstruction of existing structures or facilities) and is, therefore, exempt from environmental review pursuant to Section 15302 of the California Environmental Quality Act (CEQA).

The engineer's estimate is based on bid data for similar projects received by CMWD in 2008 and 2007, with adjustments for current conditions. The significant decrease in the bid amount as compared to engineer's estimate can be attributed to the current economic conditions and reduction in costs for materials. The total construction cost is shown in Table 3.
