REQUEST FOR COUNCIL ACTION <br />Department Approval <br />Item Description: Award Bid for 2011 Sanitary Sewer Main Lining <br />=1L 11 <br />Date: 2/14/11 <br />Item No.: 7.1 <br />40 <br />2 The majority of the city's sanitary sewer mains were constructed in the late 1950's and early <br />3 1960's. utilizing clay the pipe. Over time the joint materials have failed allowing root intrusion. <br />4, The pipe is also susceptible to cracking and construction damage. The 2011 Capital <br />5 Improvement Plan includes funding for a sanitary sewer main lining program to extend the life <br />6 of our sanitary sewers by 50 years or more. This technology essentially installs a new resin pipe <br />"7 inside the old clay the sewer main without digging up city streets, which results in minimal <br />8 disruption to residents during construction. The liner pipe is inserted into the main through <br />9 existing manholes and cured in place with a heat process. Any given segment is usually <br />110 completed in one working day. Service line connections are reopened using a robotic cutter and <br />11 remote cameras. During the process, existing flows are bypassed using pumps. This technology <br />12 has been proven over the past 20 years, and costs have become competitive with open cut <br />13 replacement. The City started doing this type of renovation in 2006 and will have an annual <br />14, project for the foreseeable future to replace our aging sewer infrastructure. This technology also <br />15 prevents infiltration of groundwater into the system and can be credited toward our inflow/ <br />116 infiltration surcharge. <br />1 ��7 <br />118 Staff assembled a specification and advertised for bids for approximately 13,181 lineal feet of <br />119 main lining in areas identified as having root intrusion or infiltration problems. Bids were <br />20 opened on January 26, 2011. <br />21 POLICY OBJECTIVE <br />22 It is city policy to keep utility infrastructure in good operating condition, utilizing current <br />23 construction technologies that keep service disruption during construction to a minimum. Based <br />24, on past practice, the City Council has awarded contracts to the lowest responsible bidder. In this <br />25 case the lowest bidder is Michels Corporation, of Brownsville, Wisconsin. <br />26 FINANCIAL IMPACTS <br />27 We received five bids for the 2011 Sanitary Sewer Main Lining Project. The low bid submitted <br />28 by Michels Corporation, $,479,868, is within the budgeted amount for this project. This work is <br />29 funded in the Sanitary Sewer Infrastructure Funds.
