Item No: 8G Meeting Date: December 8, 2014 Type of Business: Consent Agenda Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Nick DeBar, Director of Public Works Item Title/Subject: Resolution 8344, Authorizing Metro Elevator, Inc. to Repair City Hall Elevator Background/Discussion: Damage occurred to the City Hall elevator recently when the sump pump station located in the basement failed, causing water to back up in the elevator pit. The elevator pit extends approximately 4 to 5 feet below the basement floor elevation and contains a floor drain to allow any ground water to drain to the sump pump station. Fortunately, the sump pump wet water level did not exceed the basement floor elevation – which would have created water to spill across the basement floor. Ground water around the City Hall foundation is collected into perforated pipes and delivered to the sump pump wet well to be sent to the storm sewer. These pumps work very hard and water is constantly being collected in the sump wet well. The sump pumps were plugged with sand and rocks that enter the three pipe inlets which are not sealed to the sump pump wet well structure. The ground water pulls soils into the sump when the water table is high. A high level alarm that is audible and calls out an emergency number malfunctioned so Public Works was not aware of the high water level in the sump pump wet well until sometime later. Unfortunately, the elevator pit contains mechanical and electrical components that were flooded. The elevator ram and other components were contaminated and the elevator was put out of service by the state inspector until the components can be evaluated and repaired. Public Works received two quote proposals ranging from $12,756 to $22,306 from qualified elevator contractors to make the necessary repairs. The quote proposals were reviewed and discussed with the City Council at their November 24, 2014 meeting. At that time, the City Council indicated support to repair the elevator. The repair will not occur until sometime in early 2015. A copy of the quote proposal is attached for reference. Recommendation: Public Works recommends that the City Council adopt the attached resolution to authorize Metro Elevator, Inc. to repair the City Hall elevator for a contract price of $12,756. A down payment of 25%, or $3,189, is required at the time of scheduling the repair. A contingency of 10%, or $1,275, is also recommended to address additional unknown costs that found during the repair. The elevator must remain out of service until the state inspector signs off on the completed repair. Respectfully submitted, Nick DeBar – Director of Public Works
