DEPARTMENT OF WATER MANAGEMENT Memorandum No. 2010 - 04 March 10, 2010 TO: Honorable Mayor McElroy and City Coun 1 FROM: Ryan P. McCrady, City Manager Keith D. Alexander, Director of Water Management ��(' SUBJECT: Flouride Storage Tank Improvements - City Project W09-11 Construction Bid Award SUMMARY RECOMMENDATION: Council adopt the attached Resolution awarding a bid and construction contract to Repair Service Corporation (RSC) for a lump sum cost of$71,636.00. BACKGROUND: This project was first presented to Council in Apri12009 so that construction specifications could be developed. Per State regulation, flouride is added to the City's drinking water supply to reduce dental decay. The 6,000 gallon storage tank at the South Water Treatment Plant containing flouride (in solution as hydrofluorosilicic acid) has developed a small leak at the bottom and needs to be replaced before the leak becomes larger. Repairs to the existing tank are not practical due to the location of the leak and the age of the tank, which is 22 years old. Since the tank is in the basement, it has to be cut into pieces to be removed, then a new tank is custom built in place. Plans and specifications were prepared by Strand Associates and advertised for bids on February 10. Over ten companies were notified of the project, four companies requested plan sets, and only one bid was received by the March 2 deadline. Compared to Engineer's Est. Bidder Bid Price Over (-Under) Engineer's Estimate $74,500 - Repair Service Corporation(RSC) $71,636 (-3.8%) About five years ago RSC successfully completed similar work on schedule and on budget for another tank at the South Water Treatment Plant. City staff and Strand Associates recommend that the bid be accepted and a construction contract be awarded to Repair Service Corporation of Lake Zurich, Illinois. POTENTIAL OBJECTION: None foreseen. � �
