MIL-HDBK-1027/4A
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.
2.2.2.16 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.
2.2.2.17 Acoustical Control. A Noise Level Reduction (NLR) minimum factor
of 30 is required in the 70 to 75 DNL zone and an NLR minimum factor of 25 is
required in the 65 to 70 DNL zone. There are no special requirements in the
DNL zone below 65.
Conform to 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.
2.2.3
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.
Outdoor pedestrian-oriented spaces are often useful for building
entry plazas, for break and lunch areas, and to provide pleasant views from
the building interior. Design outdoor areas to harmonize with the
architectural and natural site character of their surroundings, but to also
moderate environmental and climatic extremes, such as noise, sun, wind and
seasonal precipitations.
2.2.3.1
Site Analysis and Development Concept. If the analysis and
development is successful, the biological integrity of the site will be
retained or improved, while successfully meeting the program needs of the
user in a comfortable, attractive and functional setting. Minimize clearing
of existing vegetation and avoid excessive grading.
2.2.3.2
Planting. Guidance for planting design is provided in NAVFAC
Publication P-905, Planting and Establishment of Trees, Shrubs, Ground Covers
and Vines. Plantings can provide a pleasant setting and visual asset, and
minimize the environmental impact of development. The following is a list of
minimum guidelines to be considered in implementing new planting schemes for
the facility:
a) Preserve Existing Vegetation. Existing mature stands of trees
or other significant vegetation are to be preserved and enhanced, where
possible.
