<br />VIII-A-1 <br /> <br />MEMO <br /> <br />To: <br />From: <br />Date: <br />Re: <br /> <br />Honorable Mayor and City Council <br />Tom Montgomery <br />April 1, 2004 <br />Resolutions - Approving Plans and Authorizing Advertisement for Bid, <br />Project 2004-1, Westwood Area Improvements <br />Project 2004-2, East 31 st Street Improvements <br />Project 2004-3, Vermillion River Trail and Hwy 61 Underpass" <br /> <br />Enclosed for Council approval are three resolutions approving the plans and <br />specifications for the following projects: <br />. Project 2004-1, Westwood Area Improvements <br />. Project 2004-2, East 31 st Street Improvements <br />. Project 2004-3, Vermillion River Trail and Hwy 61 Underpass <br /> <br />The three proj ects are proposed to be let as separate proj ects rather than have one <br />Contractor try to construct all of this work this year. <br /> <br />WESTWOOD AREA IMPROVEMENTS - Watermain Replacement <br />In the feasibility report and at the public hearing, the proposed Westwood Area <br />improvements included replacing about half of the existing watermain due to conflicts <br />with large ~ storm sewer main and areas with history of watermain breaks. In <br />addition all of the hydrants (20) and watermain valves (26) were also proposed. to be <br />replaced. The hydrants were to be replaced with breakaway hydrants. The valves were <br />to be replaced with modem valves with seals rather than packing. The seals will better <br />prevent leakage through the valve operating stem. <br />Following the public hearing, the Engineering Department conducted a <br />constructability review with contractors who have worked in the City previously. The <br />purpose of the review was to determine the best way to stage construction in the <br />Westwood Area to minimize impacts and disruptions to area residents. During the <br />review, a contractor noted that the numerous valve replacements were difficult operations <br />while retaining the existing watermain. Construction would be greatly simplified if all of <br />the 45 to 50 year old watermain was replaced in conjunction with the sanitary sewer <br />replacements. <br />A new estimate was prepared for watermain replacements assuming complete <br />replacement of area watermain at a construction cost of $638,000. <br />The partial watermain replacement was estimated to cost <br />$492,000. Staff is recommending revising the plans to replace all <br />0 f the watermain with funding to come from the Water Fund. <br /> <br /> <br />- - <br /> <br />ern' OF HASTIN6S <br />
