<br />.. <br /> <br /> <br />MEMORANDUM <br /> <br />DATE: <br /> <br />October 13, 2008 <br /> <br />TO: <br /> <br />Mayor and City Council <br />Ron Moorse, City Administrator <br /> <br />FROM: <br /> <br />Greg Hoag, Public Works Director <br /> <br />SUBJECT: <br /> <br />Manhole Rehabilitation Project <br /> <br />BACKGROUND <br /> <br />Staff solicited quotes from four local contactors to complete a manhole rehabilitation project <br />within a portion of the City to reduce Inflow and Infiltration (1&1). <br /> <br />Staff, working with our I & I consultant Chuck Janski, from Bonestroo have identified <br />approximately 65 manholes needing significant repairs that are related to reducing I & I. <br /> <br />Expenses incurred for this project can be credited toward the City's 1&1 surcharge. <br /> <br />DISCUSSION <br /> <br />Two proposals were received to complete this project, one from Infratech for $56,276 and one <br />from Visu-Sewer, at $68,465. <br /> <br />Staff has been in contact with Infratech, the firm who provided the lower cost, regarding a <br />schedule to complete the work this fall. Infratech is able to schedule this project for completion <br />by December 1. <br /> <br />FINANCIAL IMPLICATIONS <br />The proposal was submitted as a unit cost for the specific type of repair. As the repairs begin <br />additional repairs to specific manholes may be identified. To cover these unanticipated repairs <br />we have added a ten percent contingency to the proposal price. <br /> <br />\ \Metro-inet\ardenhills\PR&PW\Engineering\2008\Council_ Actions\l 0-13-08Memo _ Manholerehab.doc <br />
