General
Description
This Specification covers the design, fabrication and installation of pre-engineered modular shelters.
The shelter shall be a completely enclosed, personnel enclosure to protect against the environmental elements, and is intended to serve as a
smoker's shelter, or in general as a protection from inclement weather.
Manufacturer's Qualifications
Shelter framework, wall and roof paneling, equipment and related hardware shall be furnished by a manufacturer regularly engaged in the
manufacturing of such products for a minimum of five (5) years, and shall be of premium grade material, construction, and finish.
Submittals
The following drawings and documentation will be furnished:
Shop drawings shall show wall and roof panels; details of materials, fabrication, and assembly; framing profiles; fastener types and
locations, flashing, and seal details if applicable.
Erection drawings: Provide instructions and drawings, and develop erection procedures to enable field installation or repair of shelter.
Manufacturer's literature and data provide manufacturer's information for wall and roof panels, and all accessories and equipment furnished.

Product
Framing
The shelter framework shall be fabricated using 6063-T5 extruded aluminum members (FED SPEC QQ-A-200/9C(l).
Extrusion shapes shall be engineered to provide a framework of adequate structural integrity to satisfy the Uniform Building Code (UBC),
and to meet the requirements for snow, wind, and seismic loading for the location(s) being considered.
The framework shall be assembled with cadmium or zinc-coated fasteners to prevent rusting or electrolytic interaction with framing
members.
Shelter framing components and the method of fastening them to supporting foundations shall be capable of withstanding lateral loads per
ANSI A58.1, the UBC, or applicable local building codes, whichever is more stringent.
Wall, Roof, Window, Door Panels
Wall and roof panels shall be fabricated of 6mm bronze polycarbonate structured sheets (PCSS) and secured to the framing structure to
provide a safe weather-protective enclosure.
Wall and roof insulated panels shall have an insulation value of a minimum of R-6 in accordance with FED SPEC HH-T-21 B. (option)
The wall and roof panels shall also be capable of transmitting 80% of the visible light from the sun, have a high impact rating of a least 200
ft-lbs. without fracturing, and exhibit a flame spread classification (per ASTM E84) of class 1 with a flame spread of 10 or less and a smoke
density of 180 or less. |
