About this file
This document is a technical specifications attachment for a lifted platform to be installed at a designated Air National Guard Base warehouse facility. The platform must conform to precise dimensional parameters with a footprint of 22.00 ± 2 feet (length) by 18.00 ± 2 feet (width), an overall deck height of 125.25 inches, and clear under-clearance of 108.00 inches for main beams and 111.00 inches minimum for deck beams. The platform shall be a single-level open-deck configuration designed to support a uniform live load capacity of 125 pounds per square foot, a concentrated load capacity of 2,000 pounds for pallet jack loads, and a maximum column load of 300 PSI, with seismic design required for site-specific seismic zones.
The structural materials specified include 4-inch by 4-inch square structural steel tubing columns (ASTM A500 Grade B, 3/16-inch wall thickness) with 8-inch by 8-inch by 1/2-inch thick welded baseplates designed for 6-inch unreinforced 3,500 PSI concrete, American Standard Channel main beams (C15 x 33.9, 18.00 feet length) and deck beams (C12 x 20.7, 22.00 feet length) conforming to ASTM A6-79b, and 20-gauge corrugated B-deck with grate, bar, or expanded flooring to permit sprinkler suppression. Access, safety, and egress requirements include minimum 68 linear feet of gray double-rail safety handrails with integrated kickplates, one vertical safety access ladder conforming to OSHA standards, two double-rail drop-safety gates with adjustable openings of 49 to 72 inches, and all steel structural members must receive an industrial finish.
