Experience Commercial New Warehouse + Office Facility Rockford Package Supply New Warehouse + Office Facility Rockford, Michigan // 100,000 sq. ft. Client Challenge and TowerPinkster Solution TowerPinkster worked to provide Rockford Package Supply with a 100,000 SF preengineered metal building. This provided Rockford Package Supply with 90,000 SF for warehousing and an additional 10,000 SF for office space. The warehouse section also had to house a cooler/freezer and required a 2” layer of rigid insulation below the building’s slab. Our mechanical engineers worked to provide a HVAC system in the warehouse that would consist of in-wall exhaust fans and louver to sweep the air across the building. The electrical engineers designed a system that would provide 400 Amp main service with LED lighting and occupancy sensors.
