Establish an amount of $75,000 to cover the cost of unforeseen work. 4. Authorize a Budget Amendment appropriating $157,511 from the unappropriated Wastewater Fund Reserve Balance to Account No. 7532- C5600100. DISCUSSION: At 2:00 p.m. on June 17, 2002, the City Clerk opened and read the following bids for this project: BIDDER TOTAL BID AMOUNT Low Caliagua, Inc. $763,511.00 2 GCI Construction $947,100.00 Corrected Bid Amount is $762,511.00 The low total bid amount is 11 percent above the Engineers Estimate of $683,000. The low bidder, Caliagua, Inc., possesses a General Class "A" contractors license as required by the project specifications. Caliagua has satisfactorily completed similar projects for the other municipalities. PROJECT DESCRIPTION: The Buck Gully Wastewater Pump Station is located near Little Corona Beach off Ocean Boulevard in Corona del Mar. See attached Exhibit "A" for the location of all of the City's pump stations. This pump station was constructed in the 1940's when the community was less developed and its sewer load was considerably less than today's. The 50 -year old station has operated beyond its design life. The pumps are worn and obsolete. Many of the components of the station need to be upgraded to meet current State mandated codes and standards. SUBJECT: BUCK GULLY SEWER PUMP STATION REHABILITATION -AWARD OF CONTRACT NO. 3368 June 25, 2002 Page: 2 The Regional Water Quality Control Board has become more stringent in requiring agencies to maintain a "spill free" wastewater system. The Buck Gully Pump Station is directly adjacent to the Buck Gully and right above the Little Corona swimming beach. If the station fails, Staff has approximately one hour to respond and hook up a by -pass pumping unit. Replacement of the Buck Gully pumps will also include the purchase of a quieter backup generator. The project involves the construction of a new pump room, installation of new pumps and controls, demolition of the existing above ground control room, construction of a new roof structure at the same elevation as the adjacent pedestrian walkway. In addition, new drainage facilities will be constructed along with new concrete walkways to the adjacent Little Corona restroom facilities. In an effort to save time and construction costs, the Carnation and Linda Isle Pump stations were included in the Buck Gully contract. The upgrades planned for these two stations include new hatches to allow better access to the stations and electrical upgrades, including emergency generator connections. A new bypass pump connection vault is also planned at each station. Since the Buck Gully project includes the same type of hatches, electrical controls, and bypass components, construction cost savings was realized by bidding these three stations as one contract. Individually constructed these two stations would have cost 20 to 30 percent more to upgrade. PROJECT SCHEDULE AND FUNDING The project is to be completed in 130 working days (6 months). However, construction will not begin until September 15th to avoid impacts with the public during the summer. There is $680,000 of funding available in the Master Plan Sewer Pump Station Improvement Capital Improvement Account No. 7532- C5600100. The remaining $157,511 will need to be appropriated from the unappropriated reserves of the Wastewater Fund to Account No. 7532- C5600100. The three projects were estimated at $1,044,000 in the 1996 Master Plan of Sewers. The total cost for the three projects combined is $837,511, which includes $75,000 for unforeseen work.
