Item No: 8C Meeting Date: April 13, 2020 Type of Business: CB Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Don Peterson, Public Works Director Item Title/Subject: Resolution 9264, Approving the Proposal from KLM Engineering for Roof Repairs on the Ground Reservoir Background/Discussion: The Public Works Department has many responsibilities and one is to efficiently operate the water distribution system. The 2,000,000 gallon (2MG) reinforced-concrete ground reservoir was constructed in 1968 and works in conjunction with the booster station. In 2014, the City Council approved repairs to the ground reservoir (Res 8218) that included interior structural repairs, interior steel coatings, exterior structural repairs, and coating of the exterior roof and flashing. (Warranty for repairs has expired.) Staff recently had the ground reservoir inspected by KLM Engineering and upon completion of this inspection; repairs to the roof are required. Staff had KLM reach out to contractors in order to receive proposals for the needed repairs; one proposal was received from Champion Coatings of Prior Lake, MN. Champion Coatings of Prior Lake was the contractor who worked on the ground reservoir in 2014, and is familiar with the site and reservoir. The scope of the repair work will include the following: • Remove the existing coating by grinding 4-inches, including feathering the existing coating to sound material, on both sides (minimum of 8-inches wide) of expansion and construction joints, as directed by the engineer. The total footage requiring repair is approximately 522-lineal feet. • On all joint repair areas, apply 6-inch wide bond breaker tape per manufacturer’s instructions, similar to those provided by Sherwin Williams. • On areas of cracked coating, not affiliated with joint repairs, remove coating back to tightly adhered coating and feather edges. • Apply, color-matched, Sherwin Williams Envirolastic AR530 to the all repaired areas at a thickness of 60 mils to match existing coating. • Prior to tape or coating application, surfaces shall be clean and dry per coating manufacturer’s recommendation Total cost of the repair work submitted by Champion Coatings is $25,035.00; also KLM submitted a proposal for (4) inspection services, to be performed during the construction, for a cost of $4,869.00.
