Vault Construction Criteria GSA-approved modular vaults meeting Federal Specification AA-V-2737 or one of a)
Reinforced Concrete Construction (1)
Walls, floor, and ceiling will be a minimum thickness of eight inches of reinforced concrete. (2)
The concrete mixture will have a comprehensive strength rating of at least 2,500 pounds per square inch (psi). (3)
Reinforcing will be accomplished with steel reinforcing rods, a minimum of ⅝ inches in diameter, positioned centralized in the concrete pour and spaced (4)
The reinforcing is to be anchored into the ceiling and floor to a minimum depth of one-half the thickness of the adjoining member. b)
Steel-Lined Construction Where Unique Structural Circumstances Do Not Permit Construction of a Concrete Vault (1)
Construction will use ¼ inch-thick steel alloy-type plates having characteristics of high-yield and high-tensile strength. (2)
The steel plates are to be continuously welded to load-bearing steel members of a thickness equal to that of the plates. (3)
If the load-bearing steel members are being placed in a continuous floor and ceiling of reinforced concrete, they must be firmly affixed to a depth of one-half (4)
If floor and/or ceiling construction is less than six inches of reinforced concrete, a steel liner is to be constructed the same as the walls to form the floor All vaults shall be equipped with a GSA-approved Class 5 vault door. |
