Department Approval �-. l�'�, Jy REQUEST FOR COUNCIL ACTION Date: 08/10/09 Item No.: 7 j Acting City Manager Approval ��. .�: �� Item Description: Adopt a Resolution Awarding Sid for 2009 Sanitary Sewer Main Lining BACKGROUND The majority of the city's sanitary sewer mains were constructed in the late 1950'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. The City started doing this type of renovation in 2006 and will have an annual project for the foreseeable future to replace our aging sewer infrastructure. 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 5945 lineal feet of main lining in areas identified as having root intrusion or infiltration problems. The bid also includes approximately 75 lineal feet of storm sewer pipe hat has deteriorated and is in need of reinforcement. Sids were opened on July 30, 2009. POLICY OBJECTIVE It is city policy to keep utility infrastructure in good operating condition, utilizing current construction technologies that keep service disruption during construction to a minimum. Sased on past practice, the City Council has awarded contracts to the lowest responsible bidder. In this case the lowest bidder is Insituform Technologies USA, Inc., of Chesterfield, Missouri. FINANCIAL IMPACTS We received five bids for the 2009 Sanitary Sewer Main Lining Project. The low bid submitted by Insituform Technologies USA, Inc., $175,869, is within the budgeted amount for this project. This work is funded in the Sanitary Sewer Infrastructure Funds and Storm Sewer Infrastructure Funds. The following is a listing of the bids received: Page 1 of 2
