HomeMy WebLinkAbout4B, Motion to Reject Sanitary Sewer Lining Bids .. ~~LLS Request for Council Action Prepared By: Kristine Giga, Civil Engineer ~ Council Meeting Date: September 29, 2008 Motion to Reject Sanitary Sewer Lining Bids. Budgeted Amount: $100,100 Actual Amount: $88,030 Recommendation: 1. Reject bids for Sanitary Sewer Lining Project. Supporting Documents: 1. Memorandum dated September 25, 2008 from City Staff. Funding Source: Sanitary Sewer Enterprise Fund ~ MEMORANDUM DA TE: September 25, 2008 TO: Mayor and City Council Ron Moorse, City Administrator FROM: Kristine Giga, Civil Engineer Greg Hoag, Public Works Director SUBJECT: Motion to reject Sanitary Sewer Lining Bids BACKGROUND As part of the City's efforts to reduce Inflow and Infiltration (1&1), staff considered a sanitary sewer main lining project. This technology essentially installs a new resin pipe inside the old clay tile sewer main without digging underground, which results in minimal disruption to residents during construction. The liner pipe is inserted into the main through existing manholes and cured in place with a heat process. Service line connections are reopened using a robotic cutter and remote cameras. During the process, existing flows are bypassed using pumps. This technology prevents infiltration of groundwater into the system. A portion of these expenses can be credited toward the 1&1 surcharge. DISCUSSION/FINANCIAL IMPLICATIONS Staff assembled a specification and advertised for bids for approximately 1,420 lineal feet of sewer main lining in areas identified as having root intrusion or infiltration problems. Bids were opened on August 21, 2008. We received two bids for the 2008 Sanitary Sewer Main Lining Project: BIDDER I AMOUNT I Veit & Company, Inc. I $ 88,030.00 I I Lametti & Sons, Inc. I $101,960.00 \ \Metro-inet. us\ardenhills\PR&PW\Engineering\2008\Council_ Actions\9-29-08MelTIO _ RejectSewerLiningBids.doc 9/25/2008 Page 2 Staff anticipated costs to come in substantially lower, based on unit prices of past projects in neighboring cities. Unit prices have increased in the past year, which can be attributed to rising materials and transportation costs. The amount in the 2008 budget for 1&1 related work is $100,100. Since sewer main lining receives only partial credit towards the 1&1 surcharge (approximately 500/0), staff and the City's 1&1 consultant (Chuck Janski, Bonestroo) feel that the budgeted dollars should be applied towards a project(s) where 1000/0 of the costs can be applied to the surcharge, and also will be more effective in inflow reduction, such as smoke testing and a manhole rehabilitation project. RECOMMENDED COUNCIL ACTION Reject Sanitary Sewer Lining Bids.
