harness system for ease of installation.
3.1.7.7 Environmental Control Units: The shelter exterior fabric panels shall have ventilation/heating
duct access panels to accommodate and secure a minimum of two sets of 16" diameter fabric ducts. This
interface shall allow intake and exhaust from an external ECU, without loss of environmental or blackout
protection.
3.2 Operating Environment Requirements: The following conditions define the environmental limits
for the MLAMS. The erected shelter system shall provide all the following environmental conditions
without degradation in performance.
3.2.1 Wind: The erected shelter shall withstand sustained winds of 90 MPH, from any direction, in all
soil/surface conditions - including the fabric, framing, all access doors and support cabling.
3.2.2 Rain: The MLAMS shall resist intrusion of water during rainstorms though the shelter structural
members, fabric, flaps, seams, tabs, material interfaces or vents. Dripping water will not be allowed.
3.2.3 Water resistance: The shelter shall incorporate water management features designed to mitigate
rain water intrusion along the length of the shelter. The shelter is to include an external system
engineered to resist water intrusion at the arch assembly joints and the arch/fabric interface. The design
of the MLAMS shall be such that no water collects or pools on the exterior surface. Methods used to join
shelter fabric sections together shall not compromise the structural integrity of the shelter system or result
in leakage of liquids.
3.2.4 Snow and sleet: The shelter shall support a minimum threshold of 8 pounds per square foot (PSF)
balanced snow load. A 20 psf roof load with complete unimpeded interior access is the objective. The
shelter will support the designated load for a minimum of 12 hours without sustaining damage that would
