About this file
This is a Technical Specifications document for a lifted warehouse platform to be installed at a designated Air National Guard Base facility.
The platform must be a single-level structure with specific dimensional parameters: 22.00 ±2 feet (length) by 18.00 ±2 feet (width) footprint, overall deck height of 125.25 inches, and clear under-clearance of 108.00 inches at main beams and 111.00 inches minimum at deck beams. The structure must support a uniform live load capacity of 125 PSF and concentrated loads of 2,000 pounds for pallet jack operations, with a maximum column load of 300 PSI. The platform must be seismically designed for site-specific seismic zones and accommodate column center-to-center spacing of 21.30 by 17.30 feet with a minimum opening of 9 feet ±12 inches between columns.
Material requirements specify 4-inch by 4-inch square structural steel tubing columns (ASTM A500 Grade B) with 8-inch by 8-inch baseplates, American Standard Channel main beams (C15 x 33.9) at 18 feet length, and deck beams (C12 x 20.7) at 22 feet length, all conforming to ASTM A6-79b standards. The deck surface shall consist of 20-gauge corrugated B-deck with reflective white underside and grate or expanded flooring on top to allow sprinkler suppression. Safety and access features include a minimum of 68 linear feet of gray double-rail safety handrails with integrated kickplates, one vertical steel safety ladder at 125.25 inches height, and two double-rail drop-safety gates with adjustable openings of 49 to 72 inches ±12 inches, all conforming to OSHA and building code standards.
