The U.S. Army Contracting Command – Aberdeen Proving Ground (ACC-APG) is exploring options for a contractor to design and build one enclosure inside of an existing surety chamber for use with highly hazardous materials located at the Aberdeen Proving Ground, Edgewood Area, Maryland. The contractor will be responsible for measuring, designing, fabricating, delivering and installing the enclosure and delivering 100% of the design drawings.

The internal surfaces of the enclosure should be stainless steel to be compatible with bleach or caustic solutions. The desired external dimensions of the enclosure are 22 feet long, 10 feet wide, and 9 feet tall, with a minimum 6 foot tall by 4 foot wide door on each of the 22 foot long sides. The enclosure must be able to be assembled in place or assembled remotely and placed into the chamber through a door approximately 13 feet wide and 10 feet tall.

The floor of the enclosure must be level, elevated from the existing structure by approximately 6 inches, and must be able to hold the weight of four adults plus ancillary equipment (stationary and moving).

The enclosure will be operated with the surrounding chamber maintained at approximately 22 ºC and will be required to control and maintain temperature from 0 to 50 ºC, the humidity from 5% to 80% relative humidity, and a unidirectional wind speed from 2-12 meters per second across the longest side of the enclosure. The enclosure must be held at a negative pressure differential compared to the surrounding chamber. The enclosure must be able to be viewed remotely, with lighting sources and camera feeds available.

The enclosure must contain a space where exterior equipment may pass through (sensor data lines, power cables, etc). All work under this project must be completed in accordance with all applicable U.S laws, regulations, policies, and procedures.

POTENTIAL PERIOD OF PERFORMANCE: One year (twelve months) The Government will not reimburse contractors or responders to this notice for any costs incurred in responding, or any subsequent exchange of information.
