Erhardt converted an existing clarifier building that contained a 120’x120’x25’ deep water clarifying tank at the Donald K. Shine Water Treatment Plant in Holland into a vehicle storage and maintenance garage for the plant’s equipment and vehicles.
The conversion included the demolition of a large 120’ diameter clarifier and its associated structural steel supports, catwalk, motor mechanism, and filtration/weir channels. Four new structural steel columns were added to support the existing roof system prior to the clarifier being completely removed. The floor was then raised 4.5 feet to get it up to the same elevation as the exterior grade, and a new 6” thick sloped-concrete floor was placed with several new trench drains to accommodate vehicle washing, and underground plumbing for a future bathroom. Two new overhead doors were added to the north end of the building for vehicle and large equipment access, with new concrete stoops and asphalt approaches. The new HVAC system included two new 8,500 CFM make-up air units, three 5,600 CFM exhaust fans and one 24’ diameter circulation fan mounted on the ceiling. New high-bay LED lighting was added to provide ample light for maintenance on vehicles. The project commenced on March 19th, and finished right on schedule on June 25th.
