Draft DoR 3-Bay HPM Ft Polk

DRAFT Description of Requirement for a
Three-Bay High Performance Magazine (HPM)

REQUIREMENT: The U.S. Army Engineer Research and Development Center (ERDC), Geotechnical and Structures Laboratory (GSL), has a need for the procurement of materials and the on-site fabrication and assembly of one (1) complete, three-bay, monolithic High-Performance Magazine (HPM) reinforced concrete test structure. All work shall be performed in strict accordance with the specifications listed below.

1.0 DESCRIPTION OF STRUCTURE

1.1 General Overview & Configuration

The project requires the on-site, cast-in-place construction of a monolithic, three-bay HPM structure. The final deliverable will be a single, continuous test structure composed of three identical, interconnected bays. The test structure is for experimental purposes only and in the course of testing the structure will be completely destroyed and the site will be retrograded. The vendor shall mirror and repeat the structural details, reinforcement configurations, wall cavities, and dimensions of the single-bay design detailed below to assemble the three bays. Note that the structural descriptions provided herein are general descriptions for informational and market research purposes only; complete, detailed engineering drawings and specifications will be provided when the project is formally issued for solicitation and bid.

1.2 Overall Dimensions (Per Bay)

o Approximate Footprint: The primary structure of a single bay is approximately 48 feet long by 43 feet wide.
o Approximate Height: The structure stands approximately 15 feet from the finished grade to the top of the roof parapet.
o Layout: Each bay consists of internal "storage cells" and a "transport aisle," formed by a network of thick, reinforced concrete walls.

1.3 Structural Component Details

o Foundation and Floor Slab: The structure is built on a thick, reinforced concrete slab-on-grade foundation. The slab is approximately 20 inches thick and is heavily reinforced with two mats (top and bottom) of #8 reinforcing bars at 6-inch spacing in both directions. The vertical layers of reinforcement are connected by #4 stirrups at 6-inch spacing. All flexural reinforcing bars must be continuous without splices o Walls and Reinforcement Congestion: The walls form a complex, cellular system creating interior voids that will be filled with structural sand.
o Thickness and Reinforcement: Most walls are approximately 22 inches thick. They are heavily
