b. Design and construct exterior ballistic walls to prevent passage of bullets from the inside of the shoot house to exit out the exterior door.

c. Design and construct live fire shoot house walls with SECURE 500 steel at least 16 mm thick and covered with 10 cm ballistic rubber capable of stopping and encapsulating live fire rounds. (Brinell hardness approx. 500)

d. The design and construction of portable bullet traps, one per room, which meet live fire shoot house safety standards.

e. Other elements must include but are not limited to foundations, flooring which allow rubber siding of ballistic wall panels to be taken off and replaced during maintenance, superstructure (i.e. walls, columns and beams), lateral load stability, diaphragm design, and framing.

The Contractor must have as part of his design team a licensed structural engineer per Host Nations standards. If work is being performed in a country that does not have licensed structural engineers, then engineering degrees along with extensive structural design experience can be submitted to the KO for qualification verification and approval. The structural engineer’s licensure or qualifications must be submitted to the KO in the design quality control plan prior to the start of design. The Contractor’s structural engineer must be responsible for the design of any part of the building structural systems.

The structural design of the foundation, superstructure and any other structural aspects must be in accordance with the design criteria listed in this document.

The superstructure of the project building and the foundation must be constructed from locally available materials.
