MIL-HDBK-1027/4A
Areas hazardous to handicapped persons need not be accessible. Comply with
current criteria in Uniform Federal Accessibility Standards (UFAS).
3.2.2.12 Elevators and Stairs. Comply with requirements of DM 3.09,
Elevators, Escalators, Dumbwaiters, Access Lifts, and Pneumatic Tube Systems
and handicapped criteria in UFAS. For safety related measures, comply with
ASME/ANSI A17.1, Safety Code for Elevators and Escalators, and NFPA 13,
Standard for the Installation of Sprinkler Systems.
Provide freight elevators where stairs cannot accommodate the
weight and size of routinely transported equipment. Consider the weight
associated with transporting security vaults or training equipment to upper
levels. Provide stair tread nosings that are resistant to heavy trainee
pedestrian traffic volume.
3.2.2.13 Access Floor Systems. The underfloor space must be properly sealed
if used as an air conditioning supply plenum. Use plastic laminate covering
for access floor panels. Provide access flooring in computer rooms and in
administrative spaces where networks are used.
3.2.2.14 Ceilings. Provide access where projection, mechanical and
electrical equipment, including adjustment, maintenance and shutoff devices,
are located. Ceilings should be maintainable and easily repaired.
Projections from the ceiling such as sprinklers and light fixtures
can impinge on clearances required for device installation and removal, as
well as crane and hoist operations. Coordinate all ceiling items on a
comprehensive reflected ceiling plan.
3.2.2.15 Walls. Impervious finishes applied to the interior side of
exterior walls must be carefully evaluated against dew points to prevent
vapor dams and subsequent failure of the installation. Protect the corners
of walls and columns in areas where equipment moves are frequent.
3.2.2.16 Acoustical Control. A Noise Level Reduction (NLR) minimum factor
of 30 is required in the 70-75 DNL zone and an NLR minimum factor of 25 is
required in the 65-70 DNL zone. There are no special requirements in the DNL
zone below 65.
Use noise and sound transmission criteria cited in DM 1.03,
Architectural Acoustics. Prevent sound transmission over walls. Acoustic
absorbing material should be fire and smoke rated as required in MIL-HDBK-
1008C.
3.2.3
Landscape Architecture. The framework for planning and design of
all landscape architectural elements is found in the activity Master Plan and
more specifically in the Base Exterior Architecture Plan (BEAP). General
guidance for all design elements can be found in NAVFAC P-960, Installation
Design. Landscape design must enhance positive image for the facility and
should direct pedestrians to a primary entry. Design for minimal
maintenance. Provide landscape fabric for weed prevention. Select hardy
specimen species indigenous to the area. Locate hose bibbs convenient for
additional irrigation.
