�;.� EN HILLS <br />MEMORANDUM <br />DATE: May 24, 2010 <br />TO: Honorable Mayor and City Council Members <br />Patrick Klaers, City Administrator <br />FROM: Kristine Giga, Civil Engineer <br />SUBJECT: 2010 Sanitary Sewer Lining Project- Award Bid <br />Background <br />The maj ority of the city' s sanitary sewer mains were constructed in the late 19 5 0' s and <br />early 1960's, utilizing clay tile pipe. Over time the joint materials have failed allowing <br />root intrusion. The pipe is also susceptible to cracking and construction damage. The <br />2009 Capital Improvement Plan includes funding for a sanitary sewer main lining <br />program to extend the life of our sanitary sewers by 50 years or more. This technology <br />essentially installs a new resin pipe inside the old clay tile sewer main without digging up <br />city streets, which results in minimal disruption to residents during construction. The <br />liner pipe is inserted into the main through existing manholes and cured in place with a <br />heat process. Any given segment is usually completed in one working day. Service line <br />connections are reopened using a robotic cutter and remote cameras. During the process, <br />existing flows are bypassed using pumps. This technology has been proven over the past <br />20 years, and costs have become competitive with open cut replacement. This <br />technology also prevents infiltration of groundwater into the system and can be credited <br />toward our inflow/ infiltration surcharge. <br />Staff assembled a specification and advertised for bids for approximately 3,409 lineal feet <br />of sewer main lining in areas identified as having root intrusion or infiltration problems. <br />A location map is attached. Bids were opened on May 20, 2010. <br />Discussion <br />Based on past practice, the City Council has awarded the contract to the lowest <br />responsible bidder. In this case, the lowest bidder is Lametti & Sons, Inc., of Hugo, <br />Minnesota. <br />City Council Meeting <br />\�1Vletro-inet.us\ardenhills�PR&PW\Engineering\Council_Actions\2010\5-24-10Memo_SewerLining_AwardBid.doc <br />Page 1 of 2 <br />
