<br />Memorandum <br /> <br />. Bonestroo <br /> <br />To: <br /> <br />Centerville City Council <br /> <br />Projed: 2009 Street and Utility <br />Improvement Project <br /> <br />Client: City of Centerville <br /> <br />Date: 7/23/2008 <br /> <br />2335 Highway 36 W <br />St. Paul, MN 55113 <br /> <br />Tel 65H36-4600 <br />Fax 651-636-1311 <br /> <br />From: <br /> <br />Design Team <br /> <br />Re: <br /> <br />Bolt Replacement on Mill & Overlay Streets <br /> <br />File No: 616-07158-0 <br /> <br />www.bonestroo.com <br /> <br />This memo concerns the question of whether bolt replacement should be added to the upcoming street <br />improvement project on Mill and Overlay streets. <br /> <br />The cost estimate below addresses the impact of excavation and replacement of water main bolts on gate <br />valves and hydrants. The cost to excavate and replace bolts is approximately $2,500 per gate valve or <br />hydrant. <br /> <br />Street Estimated Cost <br />Brian Drive $30,000 <br />Brian Way $7,000 <br />Clear Ridge $10,000 <br />Fox Run $17,000 <br />Grainge View $5,000 <br />Total Estimated Cost for Mill and $69,000 <br />Overlay Streets <br /> <br />Please note that the estimate does not include replacement costs for tees, bends, or other fittings. <br /> <br />Due to corrosive soils numerous bolts have failed in the past within Centerville. The cost to repair these <br />water main breaks as they occur is approximately $5,000 per occurrence. Based on City Public Works Staff's <br />past experience with water main breaks, it is recommended that these replacements be added to the <br />project. <br />
