{1W lHG -ASSO(IIT[S TUUC MOMfl Memo TO: Honorable Mayor and City Council Members FROM: Lee Elfering, City Engineer DATE: February 8, 2012 RE: Interceptor 1 -LC -420 Joint Repair Project As described in our previous memo the above referenced project is a cooperative project between the City of Little Canada and Met Council for the rehabilitation of an existing sanitary sewer interceptor that is being tuned back to the City. The previous memo outlined the results of the bid and informed the Council that bid tabulation had been provided to Met Council for their review and approval of award. We have received notification from Met Council that they have completed their review of the bid and would recommend approval of the Contract. The base bid items of the project are costs associated with the mainline and structure improvements and are the costs that will be reimbursed to the City by Met Council. This portion of the project required Met Council approval for award. The alternate bid schedule is for service work that would be the responsibility of the City. This work involves the mechanical grouting of the service connections to the mainline sewer and the first 4 feet of the service. The number of services included in the bid was estimated based on mineral deposits and actual - infiltration seen on the most current televising videos. Based on the unit prices received we feel that the alternate should be awarded, however the actual quantity to be used should be based on an inspection of the services after the initial cleaning of the mainline sewer to help determine if a grouting of the service connection is a cost effective means of eliminating inflow and infiltration or if the infiltration is coming from inside the service line itself. Based on the receipt of Met Councils approval for award we would recommend award of the base bid and alternate to the low bidder Infratech in the amount of $404,749.00. As indicated above the alternate bid quantities used will be based on a re- inspection of the services and a determination of cost effectiveness. The actual number of services grouted is expected to be within the range that was bid.
