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