Approve the design build approach for completion of this project. 2. Award Contract No. 3506 to Rich Construction for the Total Design /Build Price of $92,084.18, and authorize the Mayor and the City Clerk to execute the contract. 3. Establish an amount of $9,200 to cover the cost of unforeseen work. DISCUSSION: The City Council approved the installation of an emergency backup generator at the Zone V Water Pumping Station in this year's Capital Improvement Program. The station serves the higher elevations of Newport in the Spyglass Hill area and has no automatic backup supply in case of power outages. When an outage occurs, Utilities Staff are deployed with a backup water pump driven to the site and activated. This deployment can take up to an hour during which time the residents have no water for potable use or fire suppression. The installation of a new emergency backup generator would automatically engage if a power outage occurs, no loss in water or fire supply would be realized. The project includes installation of a 100 Kilowatt emergency generator and automatic transfer switch, electrical conduit and wiring, concrete pad, and decorative block wall stuccoed to match the existing facility. DESIGN /BUILD CONCEPT The normal process for constructing public works contracts is to develop plans and specifications, advertise for bids, and award the contract to the lowest responsible bidder. The development of the plans and specifications for this project are estimated to cost $15,000 and would take approximately 3 to 4 months to develop. The bidding process adds another 2 months to the process and would cost approximately $3,000 in administration costs. Staff estimates a bid price if the project went to formal bid would Subject: Zone V Backup Generator — Award of Contract No. 3506 February 12, 2002 Page: 2 be $80,000 to $90,000 range with the total project cost range from $100,000 to $110,000. Rich Construction is a current City contractor upgrading the Zone III and IV pumping station at Big Canyon, which includes a backup emergency generator for Zone III. Rich Construction was contacted about the Zone V project and asked to provide their expertise to the design process. During the discussions it became apparent that a design build approach might save the City time and money when completing the Zone V project. Rich Construction is already mobilized at the Big Canyon site and has been a good contractor to work with. They are a general and electrical contractor, which allows generator installation. Staff negotiated a quote from Rich Construction to complete the installation of the emergency generator, which includes providing a design plan. The City's consulting electrical engineer, Mark Balan, reviewed the $92,084 quote the City received. He felt the quote was fair and saves the cost and time of the formal design approach. The major cost component of $53,289 is for the generator, automatic power transfer switch and electrical controls. With the assumption that Southern California Edison may have more power outages this upcoming summer, Staff would recommend approval of the design /build approach and award of contract to Rich Construction. Project funds are available in the Zone V Emergency Generator Capital Improvement Account No. 7503- C5500531. The installation will take four months to complete and will be fully operational before the summertime peak water demands. Respectfully PUBLIC WORKS DEPARTMENT Stephen G.
