DEPAR'T'MENT HEAD'S APPROVAL: CITY MANAGER'S APPROVAL: No comments to supplement this report 0 Comments attached Recommendation: To approve Proj"-9, Old Highway 8 NW Watermain Upgrade, approve the plans and specifications, and authorize staff to advertise for bids. Legislative History: The City Council authorized entering in a contract with Bolton & Menk, Inc. for engineering services for this project on June 9, 2009. Financial Impact: The estimated project cost breakdown for Project 09-9 is as follows: Watermain Construction $ 232,950 Access Trail Construction $ 64,500 is Engineering & Admin $ 58,550 Contingencies (10%) $ 29,750 Total Estimated Project Cost $ 385,750 This project cost estimate is higher than the preliminary estimate because of refinements made in the design and also more accurate and up to date construction cost information being used in preparing the estimate. Actual construction costs will be known the time of the bid award at which time the Council will decide whether to proceed with the project or not. Explanation: Currently, the only watermain servicing the entire NE portion of the City is an 8 -inch cast iron watermain installed in 1963. Some of the industrial businesses along the Old Highway 8 NW corridor have experienced low flow alarms when the 8 -inch is disrupted. Given our current system demand from the industrial park located north of Highway 96, a new hotel at Highway 96 opening this December, and the future water demand of the Northwest Quadrant area, it is strongly recommended the 8 -inch pipe be upgraded to a 12 -inch pipe. As part of the Old Highway 8 Reconstruction project, a 12 -inch watermain was constructed from 1-694 and extended past the Long Lake Regional Park entrance. This project will connect to the new 12 -inch near the park entrance and 2,800 linear feet of watermain will be directionally drilled along the west side of Old Highway 8 to south of Applewood Point just north of Highway 96. The new 127 unit hotel currently under construction and scheduled to open this December, will not be put out of service by constructing this watermain in the fall of 2009. The remainder of the loop will be coordinated with future construction projects. Also, included in this project is the construction of an access trail to the existing sanitary sewer as shown on the attached drawing.
