<br />City Council Regular Meeting - 09/12/05 <br />Minutes - Page 9 <br /> <br />6. <br /> <br />OVAL Repair Update <br />Parks and Recreation Director Lonnie Brold(e and Brad Tullberg, <br />Skating Center Superintendent were present to provide an update <br />on repairs; and to answer questions of the Council. <br /> <br />Mr. Brokke reviewed the schedule to-date; five major <br />components of the refrigeration system and vulnerable areas (i.e., <br />chiller barrel; evaporation tower; brine pump and piping system; <br />outside surface area; compressor/ammonia piping system. <br /> <br />Mr. Brol~e reviewed the initial proposals, additions and <br />deletions, and additional problems encountered with the brine <br />piping and insulation system; noting that work was continuing to <br />get done properly and expediently; with expenses still within the <br />Guidant contribution, and totaling approximately $400,000 to- <br />date. Mr. Brokke advised that the additional cost option to <br />replace corroding pipes from the original proposal of $75,000 <br />would be an increase totaling $117,000. <br /> <br />Mr. Brokke reviewed in more detail issues with the chiller barrel <br />and the re-tubing process, the evaporation tower, and brine pump <br />and piping systern. Mr. Brokke noted that an unexpected <br />additional expense will be replacing the piping, which was <br />showing extensive corrosion on some areas. Mr. Brokke further <br />noted, however, that the six zone, outside floor area had been <br />flushed, and appeared stable, with further testing to ensure all <br />ammonia had been flushed prior to replenishing brine. <br /> <br />Mr. Brokke reviewed the payment schedule, with the first <br />contractor invoice anticipated soon (for approximately 50%), to <br />be verified by staff and representatives of Steven's Engineering, <br />provided to Friends of the Oval Foundation (FOF), with payment <br />to the City by FOF for processing to the contractor(s). <br /> <br />Mr. Brokke reviewed potential challenges to be faced in the <br />future; and noted the upcoming meeting of the OV AL Advisory <br />Committee on September 21, 2005 to review, assess, and <br />implement Task Force recommendations for operation and <br />maintenance. <br /> <br />Mr. Brokke provided a detailed analysis of the financing: with a <br /> <br />OV AL Repair <br />Update <br />
