Telephone, cable television, convenience outlets, and mechanical
ducts should not compromise the acoustical integrity of wall, floor,
or ceiling assemblies.
Select fluorescent lamp ballasts to minimize noise generation.

STRUCTURAL SELECTION. Coordinate column spacing and
layout with the building's floor plan so that they occur within or in alignment with
walls. Hold columns occurring within spaces to a minimum and limit them to
larger public spaces. Analyze the proposed structural system that is the most
economical method of realizing the architectural design intent. Select an
economical structural system based on:
Facility size;
Projected load requirements;
Subsoil conditions;
Local availability of materials and labor;
Feasibility of prefabrication;
Local construction practices;
Resistance to fire, wind, snow, seismic, geologic, and permafrost
conditions as dictated by the location.

VAPOR BARRIERS. Calculate vapor permeability and
temperature through the entire wall sections including interior finishes to ensure
dew point does not occur within the wall system. Special construction
considerations not limited to heating, ventilating, and air conditioning (HVAC)
systems are required in humid areas.
10-31
ROOF SYSTEMS. Design and detail roof systems to resist
maximum wind for the area. Provide a residential character through the use of
gable or similar sloped forms.
10-32
DOORS. Specify doors, frames, and hardware to meet sound
separation, fire separation, and security requirements unique to Navy and Marine
Corps Bachelor Housing. All doors and frames must be designed and installed in
accordance with the findings of the Threat Assessment Study provided for the
project.
Exterior doors should be fully weather-stripped and include a
heavy-duty metal threshold that prevents drafts, dirt, water, and
