Item No: 7D <br />Meeting Date: March 10. 2014 <br />Mo� <br />+ g Type of Business: Council Business <br />�i i Administrator Review: <br />City of Mounds View Staff Report <br />mommommommommor— <br />To: Honorable Mayor and City Council <br />From: Nick DeBar, Director of Public Works <br />Item Title/Subject: Resolution 8224, Awarding a Construction Contract for 2014 2MG <br />Ground Reservoir Rehabilitation Project <br />Background/Discussion: <br />The 2,000,000 gallon (2MG) reinforced -concrete ground reservoir was constructed in 1968 and <br />works in conjunction with the booster station. The reservoir has performed well but has been <br />showing signs of deterioration the past several years, most notably the masonry and roof <br />conditions. The reservoir was inspected by KLM Engineering, Inc. to determine condition and <br />rehabilitation scope of work. <br />The Council authorized KLM to perform engineering design and prepare bidding documents for <br />the reservoir rehabilitation on January 27, 2014 (Res. 8208). Rehabilitation includes interior <br />structural repairs, interior steel coatings, exterior structural repairs, and coating of the exterior <br />roof and flashing. The estimated cost estimate to perform the repairs and rehabilitation is <br />$407,100 and will extend the service life of the reservoir by 30 to 40 years. A new tank of <br />similar construction is estimated at $3 to $4 million. <br />The Council approved bidding documents and authorized advertisement for bids on February <br />24, 2014 (Res. 8218). A pre-bid conference was conducted on March 3, 2014 and bid <br />proposals are due March 10, 2014. <br />Recommendation: <br />Public Works Engineering will evaluate the bids received on March 10, 2014 and make a <br />recommendation for award later that day at the City Council meeting. This project is on a fast <br />track and if rehabilitation work is to be completed, the reservoir will need to be back on-line <br />prior to the irrigation season (traditionally around June 1). While the drinking water system <br />could meet the typical summer demand, it would require increased wear and tear on the well <br />pumps and motors and may require a ban on lawn sprinkling. Rehabilitation work is expected <br />to take six to eight weeks to complete. <br />Monies have been budgeted under the water enterprise fund (700-4823-7050) for $350,000. <br />Respectfully submitted, <br />Nick DeBar — Director of Public Works <br />
