Installation of interior slabs on grade for large distribution centers can be both simple and complex: simple in that slabs are large, open areas, flat and generally free of obstructions; complex in the difficulty of maintaining an aggressive schedule, controlling the placing environment, and ensuring consistency in materials and workmanship. Through careful planning, communication, and attention to detail, the project team for the new Ace Hardware Distribution Facility in Loxley, Ala., installed a high-quality slab at a blistering pace.
This 800,000-square-foot project had a 6-inch thick slab, and a pinwheel column design with square columns and round dowels at the construction joints. Bays are 54x54 feet with a 13.5-foot control joint spacing. Around docks where high traffic was expected, the slabs were reinforced to minimize crack widths and curling.
