Item No: 7I Meeting Date: December 10, 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 8032, Approving Additional Expenditures for Repairs and Improvements to the Gymnasium Floor at the Community Center Background: One of the two drinking fountains in the gymnasium at the Community Center sprang a leak overnight between November 2nd and 3rd, 2012. Unfortunately, a large portion of the hardwood floor in the southeast corner of the gym was soaked with water, making some boards to curl several days later and a portion of the floor heaved up about a week later. The City Council approved repairs to the damage floor and a buff and coat to the remaining gym on November 26, 2012 for an amount not to exceed $12,000. Twin City Hardwood Flooring was hired to repair the approximately 600 square feet of damaged floor and buff and recoat the remaining gym for $10,090. The repair involves removing and replacing the underlying plywood (two layers) and hardwood planks, sanding the patched area, applying two coats of sealer, and reapplying any game lines removed. Discussion: Twin City Hardwood Flooring began work on December 3, 2012 and during the removal of the damaged floor, more water was discovered below the floor beyond the removal limits. Additional curling of hardwood planks was noticed and a number of inspection holes were cut down on the easterly half of the gym which water was observed, potentially expanding the scope to removing one-third to one-half of the entire gym floor. A third party gym floor consultant was contacted and a claim was made to the City’s insurance agent (LMCIT). The consultant suggested removing sections at a time until the areas with water were exposed. The insurance agent provided staff with a contact for a restoration specialist contracting firm who provided a quote to pump air under the floor to remove the water and moisture from the floor and wood. However, the scope of work has now increased for repairing the floor and additional expenditures are needed. Twin City Hardwood Flooring provided a quote for additional compensation at a unit price of $65 and $35 an hour for a journeyman and apprentice, respectively, plus materials for additional tear- out work required. Tear-out areas requiring full restoration were quoted at $7.75 per square foot, and sanding and sealing of areas not requiring tear-out at $1.30 per square foot. Recommendation: Public Works recommend that the City Council adopt the attached resolution to approve additional unit price expenditures for the hardwood floor repair at the Community Center gymnasium. This will be an iterative process to determine what areas will require full-tear out or sanding/coating or buffing/coating. Respectfully submitted, Nick DeBar - Public Works Director
