Item No: 7E Meeting Date: January 23, 2012 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Nick DeBar, Public Works Director Item Title/Subject: Resolution 7890, Approving Bidding Documents and Authorizing Advertisement for Bids for 2012 Water Tower Reconditioning Project Background: The City’s 500,000-gallon elevated, fluted-column water tower was constructed in 1992. At that time, Mounds View had two water towers and dismantled both after constructing the current one. The water tower paint coating was inspected and had spot repairs done in 2003. Properly installed paint coatings should provide 15 to 20 years of service life. The tower is now 20 years old and in need of a refurbishing. In 2009, the City hired KLM Engineering, Inc. of Lake Elmo, Minnesota, to inspect the entire water tower and prepare an inspection report. The interior and exterior of the tank was examined and evaluated by KLM, including a “float-down” inspection performed inside the tank, on August 18, 2009. In addition to determining the interior and exterior coating replacement, the report identified some miscellaneous structural modifications and repairs required to bring the tower into compliance with OSHA regulations, AWWA standards, and better/safer access in and on the tank. Based on the inspection data, the structural repairs and coating replacement was recommended to be completed within one to three years (2010-2012). The estimated project cost was $523,500 at that time. Additional costs may be incurred with antenna work. In February 2011, the City hired KLM to prepare technical specifications and drawings for bidding and construction documents for a 2011 construction schedule. The scope of work involved partnering with the City’s engineering staff to prepare the plans and specifications jointly. Based upon this arrangement, KLM has provided the City with a fixed fee estimate of $2,800 for design/bid phases and $45,255 for construction management/inspection (total $48,055). Additional costs may be incurred associated with the antenna leases. A neighboring city spent over $100,000 in consulting fees a few years ago for the traditional consulting engineer-coatings engineer when they reconditioned their water tower. Due to unfavorable weather and an unusually large amount of other municipal water tower reconditioning projects last summer, coupled with conflicts with Festival in the Park, the project was postponed and rescheduled for a 2012 construction schedule. Discussion: Bidding documents have been prepared jointly by KLM and City staff and are being readied for solicitation of construction bids. The project will include full repainting of the tower’s exterior, the interior tank, and a partial repainting of the interior of the column. There is also many exterior and interior structural repairs that need to occur before painting that are also included in the construction documents. A public bid is required since the construction costs will exceed $100,000.
