A��rak s�l: REQUEST FOR COUNCIL ACTION ��. �r 1��i�v��: Item Description: Award Bid for Sanitary Sewer Main Lining DATE: 9111106 ITEM NO.: �,� Agenda Section: Consent Background: The majority of the city's sanitary sewer mains were constructed in the late 1950's and early � 960's, utilizing clay tile pipe. Over time the j oint materials have failed allowing root intrusion. The pipe is also susceptible to cracking and construction damage. The 2006 Capital Improvement Plan includes funding for a sanitary sewer main lining program to extend the life of our sanitary sewers by 50 years or more. This technology essentially installs a new resin pipe inside the old clay tile sewer main without digging up city streets, 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. Any given segment is usually completed in one working day. Service line connections are reopened using a robotic cutter and remote cameras. During the process, existing flows are bypassed using pumps. This technology has been proven over the past 20 years, and costs have become competitive with open cut replacement. We expect that this type of renovation will become an annual project for the foreseeable future as our sewer infrastructure continues to age. This technology also prevents infiltration of groundwater into the system and can be credited toward a required inflowl infiltrationprogram. Staff assembled a specification and advertised for bids for approximately 3600 lineal feet of main lining in areas identified as having root intrusion or infiltrationproblems. Bids were opened on August 31, 2006. Policy objectives: It is city policy to keep utility infrastructure in good operating condition, utilizing current construction technologies that keep service disruption during construction to a minimum. Based on past practice, the City Council has awarded contracts to the lowest responsible bidder. In this case the lowest bidder is Veit & Company, Inc., of Rogers, Minnesota. Financial implications: We received four bids for the 2006 Sanitary Sewer Main Lining Project. The low bid submittedby Veit & Company, Inc., $101,204, is within the budgetedamount for this project. This work is funded in the Sanitary Sewer Utility.
