Renovation of a warehouse / distribution facility in Gwinn, Michigan. Completed plans call for the renovation of a warehouse / distribution facility.

o Provide and install an indirect 5,000 cfm, gas fired make up air unit located outdoors on a grade mounted stand. The unit would be 100% outside air and ducted through the storage warehouse area. o In the storage warehouse, provide and install an exhaust system to keep a slight negative pressure with respect to the exterior and office area. The exhaust fan/s should be wall mounted for easier serviceability. The exhaust inlet being located across the building from the supply outlets would create a sweeping of the air from location of supply discharge to exhaust removal. The exhaust should pull from both high in the space as well as low to the floor to capture contaminants both lighter and heavier than air. o Provide maintenance to the existing seven gas fired wall mounted units in the storage warehouse, to be used as backup heat source in the cold months. o In the office area there is an existing ERV and ductwork, replace the ERV with a new ERV capable of 2000 cfm supply unit with 1200 cfm of return/exhaust providing an 800-cfm positive offset in the office area. This ERV should run continuously to maintain the differential. The existing duct work shall be maintained and extended into all rooms that have a door into the storage warehouse. The existing ACT grid and tile will remain, contactor will be required to remove and replace the existing tiles during installation. Patch and repair any roof penetrations or revisions from the upgrade of the system. o Provide and install weather stripping at the four doors between the office and warehouse to prevent air leakage between the spaces. o Provide Closers to the existing four doors between the office and storage warehouse. o Contractor to coordinate with SEMCO to provide new gas line, meter, and regulators to the building capable to run all mechanical equipment simultaneously. o Hire third party commissioning agent to provide test and balance of the system upon completion.
