About this opportunity
The U.S. Army Contracting Command - Aberdeen Proving Ground is seeking a contractor to design and build a specialized environmental enclosure within an existing surety chamber for handling highly hazardous materials at Aberdeen Proving Ground, Maryland. The contractor must measure, design, fabricate, deliver, and install the enclosure with complete design drawings, featuring stainless steel internal surfaces compatible with bleach or caustic solutions. The enclosure must maintain precise environmental controls including temperatures from 0 to 50°C, humidity from 5% to 80% relative humidity, unidirectional wind speeds of 2-12 meters per second, and operate under negative pressure differential. This solicitation is structured as a request for preproposals (white papers) under the broader CWMD BOTAA-24-01 framework, with the government intending to award through Other Transaction Authority. Preproposals are due October 14, 2025, and will be evaluated based on technical merit, military relevance, technology readiness level, key personnel qualifications, and best value considerations.
This opportunity carries no set-aside designation and does not identify any incumbent contractors or specific budget ranges. The enclosure specifications call for external dimensions of 22 feet long by 10 feet wide by 9 feet tall, with minimum 6-foot by 4-foot doors on each long side and an elevated floor capable of supporting four adults plus equipment. The unit must be designed for assembly either in place or remotely, then transported through a 13-foot wide by 10-foot tall chamber door. Performance will occur at Aberdeen Proving Ground in the Edgewood Area of Gunpowder, Maryland, with the enclosure required to include remote viewing capabilities through integrated lighting and camera systems. The procurement follows a two-stage process where successful preproposal submissions may be invited to submit full proposals within 60-90 days.
