persons, as well as the bathroom on the upper floor, need not be accessible.
Comply with current criteria in UFAS. See MIL-HDBK-1190.
3-3.3
Structural Design.
Design in accordance with UFC 1-200-01. Base an economical structural system
on facility size, projected load requirements, quality of local available materials,
local labor and construction materials, and local wind, snow, seismic, geologic,
and permafrost conditions. Design structural systems to support roof-mounted
and/or suspended loads, when required.
3-3.3.1
Lateral Loads.
Design all buildings and towers (antenna supports) to withstand wind and seismic
loads appropriate to the region in which they are to be constructed. See UFC 1-
200-01. Seismic analysis of government-furnished buildings and antenna
supports is not required.
3-3.3.2
Antenna Supports.
Before undertaking unique antenna support designs, consider the use of existing
commercial products suitable for the purpose. Navy standard designs for
UHF/VHF and ASR antenna supports are available. See Figure 19, "Radio
Antenna Tower" and Figure 20, "ASR Antenna Tower".
3-3.4
Reflective Surfaces.
To prevent mirror like reflections from building surfaces to aircraft in flight,
provide roofs and other external surfaces with a specular reflectance compatible
with the location of the building on the airfield. If the building is so located that
glare may be an operational hazard, provide the critical surfaces of that building
with a light reflectance of not more than 10, measured at an angle of 85-degrees
in accordance with American Society for Testing and Materials (ASTM) D 523,
Standard Test Method for Specular Gloss.
3-3.5
Permanent Floors.
Consider the placement of cables and wiring for electronic equipment when
selecting floor construction. The preferred method of placing cables and wiring is
given in the BESEP for the facility. All ATC operational spaces and equipment
rooms must have access flooring with an equipotential plane conforming to FAA-
Requirements for Facilities and Electronic Equipment and FAA-STD-020B,
Transient Protection, Grounding, Bonding and Shielding Requirements for
Electronic Equipment. See SSCC FRD.
