REQUEST FOR COUNCIL ACTION Date:December 8, 2014 Item No.: 7.c Department Approval City Manager Approval Item Description: Approve Resolution Awarding Bid for 2015 Sanitary Sewer Main Lining B ACKGROUND 1 The majority of the city’s sanitary sewer mains were constructed in the late 1950’s and early 2 1960’s, utilizing clay tile pipe. Over time the joints have failed allowing root intrusion. The pipe 3 material is also susceptible to cracking and construction damage. The City began the sewer lining 4 program in 2006 to rehabilitate the sewer mains and extend the life of our sanitary sewers by 50 5 years or more. Lining technology essentially installs a new resin pipe inside the original clay tile 6 sewer main without digging up city streets, which results in minimal disruption to residents during 7 construction. The liner pipe is inserted into the main through existing manholes and cured in 8 place with a heat process. Each segment is typically completed in one working day. Service line 9 connections are reopened using a robotic cutter and remote cameras. During the process, existing 10 flows are bypassed using pumps. This technology also prevents infiltration of groundwater into 11 the main system and can be credited toward our Metropolitan Council Environmental services 12 inflow/ infiltration surcharge. 13 The 2015 Sanitary Sewer Main Lining Project includes lining for approximately 32,186 lineal feet 14 (6.09 miles) in areas identified as having root intrusion or infiltration problems. A bid alternate 15 was also included, which would add an additional 6,002 lineal feet (1.14 miles) to the project. 16 The following six bids were opened on November 19, 2014: 17 CONTRACTOR BID TOTAL A BID TOTAL B (Segment 1 + (Segment 1 + Segment 2) Segment 2 + Segment 3) Insituform Technologies USA, LLC $856,787.00 $974,733.00 Visu-Sewer, Inc. $944,945.10 $1,082,337.10 Veit & Company, Inc. $990,518.50 $1,147,067.50 $1,025,309.00 Lametti & Sons, Inc. $1,168,451.00 Michels Corporation $1,034,259.50 $1,169,489.00 SAK Construction, LLC $1,112,886.00 $1,255,780.70 PO OLICYBJECTIVE 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.
