CITYr OF RIVERSIDE CITY COUNCIL MEMORANDUM People Serving People Riverside Ali-America City HONORABLE MAYOR AND CITY COUNCIL DATE: April 27, 2004 ITEM NO: 32 SUBJECT: EVANS RESERVOIR REPAIR, AWARD OF BID NO. MA1270 - BID WAIVER RESOLUTION BACKGROUND: Riverside Public Utilities recommends the award of a contract for implementation of crack repairs to the Evans Reservoir. The project consists of repairing approximately 35 lineal feet of spalled concrete along the wall-to-roof joint of the Evans Reservoir located at 3530 Cranford Avenue. (Spalls are smafl sections of concrete that are broken off a larger sofid concrete body. In the case of the reservoir, they may be occurring due to thermal contraction of the roof slab, or because of a concentrated bearing load from the roof slab.) Spalled concrete along the wall-to-roof joint greater than six feet in length is not currently able to fully resist out-of-plane loads. During an earthquake, the additional out-of-plane loading on the walls caused by the water sloshing inside the reservoir may be enough to cause a failure of the wall. Repairing this item will address the immediate, more urgent structural deficiencies until complete seismic rehabilitation of the reservoir can be performed. The cost for the crack repair work was estimated by the Consultant to be under $50,000. Based on this estimate and due to the urgency of the repairs, Staff decided to informally bid the project in order that construction could be performed prior to the onset of the warmer spring and summer seasons, when higher water demands make taking facilities out of service more difficult. However, all three bids that were opened on April 5, 2004, exceeded the $50,000 limit set forth by the informal bid requirements. Waiver of formal bidding requirements will be necessary to award this contract. The lowest bid received was from Howard Ridley Company, Inc., of Chino, California, in the amount of $52,780.00. Staff has reviewed all provided documentation and has determined that Howard Ridley Company, Inc., has met all of the requirements of the specifications. The Board of Public Utilities approved and recommended that the City Council waive the formal bidding requirements and award a contract for the Evans Reservoir Repair, as determined by the City Council, at its regular meeting on April 16, 2004. (See attached Bid Award Recommendation for bid summary.) FISCALIMPACT: Funds are budgeted and available for this project in the Public Utilities' Water Fund, Evans Reservoir Seismic Rehab Account No. 6230000-470742. ALTERNATIVES: One alternative is to postpone the crack repair work until after the Evans Reservoir Seismic Rehabilitation Preliminary Design Report has been updated and construction of a selected seismic retrofit alternative has begun. However, due to the increased risk of failure posed by the concrete spalls, this alternative is not recommended. 32-1
