5. STRUCTURAL REQUIREMENTS
Relocatable structures should be constructed to conform with the applicable requirements of the
Uniform Building Code, as amended by DOE 6430.1A, "General Design Criteria" (or the local
building code, if the local code is enforced onsite).
Corridors should meet the requirements of the current edition of the Life Safety Code,
NFPA Standard 101.
Tents or other membrane-type structures should be constructed of tentage material
that has been tested and approved by a nationally recognized independent fire test
authority for the anticipated end use. Approval should be based on the performance
of large scale tests.
This criteria does not apply to semi-trailers and cargo containers.
Relocatable structures should be separated such that the largest fire area does not exceed the
limits imposed by the Uniform Building Code.
Exception: Relocatable structures over 16,000 square feet (1,487 square meters) in floor area
that are protected by an automatic fire suppression system should be divided into
separate fire areas by 2-hour fire-rated barriers so that no single area exceeds
16,000 square feet (1,487 square meters) in floor area. Such barriers should extend
throughout the entire height and breadth of the structure, so designed as to prevent
fire propagation through and around the barrier.
No fire area in a relocatable structure should have a MPFL exceeding limits imposed by the DOE
