HomeMy WebLinkAboutStaff Report 184-05City of Palo Alto City Manager's Report TO: HONORABLE CITY COUNCIL FROM: CITY MANAGER DEPARTMENT: UTILITIES DATE: MARCH 21, 2005 CMR:184:05 SUBJECT: REJECTION OF BIDS AND AUTHORIZATION TO RE-SOLICIT BIDS FOR WASTEWATER COLLECTION SYSTEM REHABILITATION AND AUGMENTATION CAPITAL IMPROVEMENT PROGRAM WC-03003 PROJECT 16 RECOMMENDATION Staff recommends that Council reject all bids for construction of Sanitary Sewer Rehabilitation (advertised for bid as Project 16 Sanitary Sewer Rehabilitation), and authorize staff to re-solicit bids for this project. BACKGROUND. The City's Wastewater Operations reported various problems in the project area, including increased maintenance due to plugged lines and pipe access problems. These sewer main deficiencies (may include main breaks, missing sections of pipe, sags, and roots in the pipe) were confirmed by subsequent video inspection. The replacement/rehabilitation specified in Capital Improvement Program Project WC-03003 will provide a new and structurally sound sanitary sewer piping system with improved carrying capacity and reduce current and future maintenance problems. DISCUSSION Bid Process A notice inviting formal bids for Sanitary Sewer Rehabilitation was issued on November 18, 2004, and sent to 10 builders' exchanges and 21 contractors. The bidding period was 27 days and bids were received from five contractors on December 14, 2004. See Attachment A for a summary of all bids received on the project. Bids ranged from a low of $2,608,000 to a high of $3,752,168. . CMR:184:05 Page 1 of3 Staff recommends that the Council reject the bids due to the scope and bid requirement changes as described below. Staff identified the need to include more high priority work to replace additional 430 lineal feet of sewer mains and 50 laterals as part of this project at the end of the project bidding period. The estimated additional cost is approximately $100K and is within the original budgeted amount. Re-bidding the project will allow the project scope to be increased; a more detailed and comprehensive set of plans to be prepared; and the City's requirements for a contractor's specific experience in performing large diameter pipe-bursting operations to be included in the new project scope and specifications. Rebidding a larger, more comprehensive project will reduce the City's project administration costs for the work. Staff plans to return to Council for a recommendation to award the redefined proj ect in April, 2005.
