qASPAL+E REQUEST FOR COUNCIL ACTION Department Approval Date: 2/27/12 Item No.: 7.e City Manager Approval Item Description: Approve Resolution Awarding Bid for 2012 Sanitary Sewer Main Lining 1 BACKGROUND 2 The majority of the city's sanitary sewer mains were constructed in the late 1950's and early 3 1960's, utilizing clay the pipe. Over time the joints have failed allowing root intrusion. The pipe 4 material is also susceptible to cracking and construction damage. The City started our sewer 5 lining program in 2006 to rehabilitate the sewer mains and extend the life of our sanitary sewers 6 by 50 years or more. Lining technology essentially installs a new resin pipe inside the old clay the 7 sewer main without digging up city streets, which results in minimal disruption to residents during 8 construction. The liner pipe is inserted into the main through existing manholes and cured in 9 place with a heat process. Each segment is typically completed in one working day. Service line lo connections are reopened using a robotic cutter and remote cameras. During the process, existing 11 flows are bypassed using pumps. This technology also prevents infiltration of groundwater into 12 the system and can be credited toward our Metropolitan Council Environmental services inflow/ 13 infiltration surcharge. 14 The 2012 Sanitary Sewer Main Lining Project includes lining for approximately 20,884 lineal feet 15 (3.96 miles) in areas identified as having root intrusion or infiltration problems. The following 16 five bids were obened on February 8, 2012: BIDDER AMOUNT Visu- Sewer, Inc. $457,160.35 Insituform Technologies USA, LLC $466,052.50 Lametti & Sons, Inc. $494,307.00 Michels Corporation $496,866.00 Veit & Company, Inc. $542,855.00 17 POLICY OBJECTIVE 18 It is city policy to keep utility infrastructure in good operating condition, utilizing current 19 construction technologies that keep service disruption during construction to a minimum. Based 20 on past practice, the City Council has awarded contracts to the lowest responsible bidder. In this 21 case the lowest bidder is Visu- Sewer, Inc., of Pewaukee, Wisconsin. 22 FINANCIAL IMPACTS 23 We received five bids for the 2012 Sanitary Sewer Main Lining Project. The low bid submitted 24 by Visu- Sewer, Inc., $457,160.35, is within the budgeted amount for this project. This work is 25 funded by Sanitary Sewer Infrastructure Funds. Since starting our lining program in 2006, we 26 have seen a significant reduction in the per foot cost, as shown in the graph below. These cost 27 savings will help us achieve our long term goals for the utility Capital Improvement Plan. Page 1 of 2
