Project location map. �;.� EN HILLS MEMORANDUM DATE: May 24, 2010 TO: Honorable Mayor and City Council Members Patrick Klaers, City Administrator FROM: Kristine Giga, Civil Engineer SUBJECT: 2010 Sanitary Sewer Lining Project- Award Bid Background The maj ority of the city' s sanitary sewer mains were constructed in the late 19 5 0' s and early 1960's, utilizing clay tile pipe. Over time the joint materials have failed allowing root intrusion. The pipe is also susceptible to cracking and construction damage. The 2009 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. This technology also prevents infiltration of groundwater into the system and can be credited toward our inflow/ infiltration surcharge. Staff assembled a specification and advertised for bids for approximately 3,409 lineal feet of sewer main lining in areas identified as having root intrusion or infiltration problems. A location map is attached. Bids were opened on May 20, 2010. Discussion Based on past practice, the City Council has awarded the contract to the lowest responsible bidder. In this case, the lowest bidder is Lametti & Sons, Inc., of Hugo, Minnesota. City Council Meeting \�1Vletro-inet.us\ardenhills�PR&PW\Engineering\Council_Actions\2010\5-24-10Memo_SewerLining_AwardBid.doc Page 1 of 2 Financial Implications We received �ve bids for the proj ect. The low bid submitted by Lametti & Sons, Inc., $79,839, is significantly lower than the Engineer's construction estimate of $124,815. The following is a list of the bids received: BIDDER AMOUNT Lametti & Sons, Inc. $ 79,839 Insituform Technologies USA, Inc. $ 83,832 Visu-Sewer, Inc. $ 96,331.65 Veit & Company, Inc. $ 97,652 Michels Corporation $100,999 This project is funded in the Sanitary Sewer Enterprise Fund. Because the bids came in favorably, staff will discuss the possibility of lining additional segments with the contractor. If the contractor is willing to complete additional lining as a part of the project, staff will prepare a change order for the City Council to approve.
