qASFAbhE REQUEST FOR COUNCIL ACTION Date: 2/27/12 Item No.: 7.g Department Approval City Manager Approval Item Description: Approve a Resolution to Accept the Work Completed, Authorize Final Payment, and Commence the One -Year Warranty Period on the 2011 Sanitary Sewer Lining Project 1 BACKGROUND 2 On February 14, 2011, the City Council awarded the 2011 Sanitary Sewer Lining Project to 3 Michels Corporation of Brownsville, Wisconsin. The work for this contract was finished in 4 October, 2011, and the contractor has requested final payment. This project consisted of 15,3 86 5 linear feet of sanitary sewer main lining in areas throughout the City identified as having root 6 intrusion or infiltration problems. 7 POLICY OBJECTIVE 8 City policy requires that the following items be completed to finalize a construction contract: 9 • Certification from the City Engineer verifying that all of the work has been completed in 10 accordance with plans and specifications. 11 • A resolution by the City Council accepting the contract and beginning the one -year warranty. 12 FINANCIAL IMPACTS 13 The final contract amount, $542,136.40, is $62,268.40 more than the awarded amount of 14 $479,868. This represents an increase in the contract of 13 %. The cost increase is the result of 15 two project change orders. The first was the result of staff identifying an additional 2,221 linear 16 feet of sanitary sewer main that was in immediate need of lining. The second was because the 17 liner on the 30" sewer line on Long Lake Road needed to be thicker than originally designed; this 18 was due to the high groundwater table discovered near the main. The thicker liner increased the 19 liner cost for the 30" pipe. 20 Decisions regarding this additional work needed to be made while the work was being completed, 21 not allowing for the processing of a change order prior to the execution of the work. This project 22 was funded using sanitary sewer utility funds and Metropolitan Council Environmental Services 23 Municipal Inflow and Infiltration Grant funds. 24 STAFF RECOMMENDATION 25 Since all necessary items have been completed in accordance with project plans and 26 specifications, staff recommends the City Council approve a resolution accepting the work 27 completed as the 2011 Sanitary Sewer Lining Project and authorize final payment of $164,788.42. 28 REQUESTED COUNCIL ACTION 29 Approve the resolution accepting the work completed as 2011 Sanitary Sewer Lining Project, 30 starting the one -year warranty and authorizing final payment.
