Framing. Structural framing shall conform to the criteria in
NAVFAC DM-2 series Structural Engineering.  Roof framing shall be designed to
support all roof-mounted equipment.
Exterior Walls.  Unless otherwise specified, walls shall be masonry
units, or, for certain buildings, precast or cast-in-place concrete.  Wall
construction shall be consistent with the requirements of NAVFAC DM-1.01,
Basic Architectural Requirements & Design Considerations.
Interior Walls
Permanent Partitions.  Interior partitions for stairwells, vaults,
elevator hoistways, toilets, and other areas requiring fixed partitions shall
be masonry units or concrete.  Partitions in storage areas shall be of
concrete masonry.
Nonpermanent Partitions.  Interior partitions in electronic
operating spaces shall be nonload-bearing and removable.  Electrical power and
control wiring shall not be located in these partitions.  Permanent partitions
separating electronic operating spaces from other spaces shall be fire rated
and constructed in accordance with National Fire Protection Agency (NFPA) 75,
Computer/Data Processing Equipment.  All partitions using metal framing and/or
surfacing shall be suitably bonded and grounded, if required by SPAWAR.
Permanent Floors.  Selection of floor construction should take into
consideration the placement of cables and wiring for electronic equipment. An
equipotential plane conforming to MIL-HDBK-419, Volume 1, Grounding. Bonding,
and Shielding for Electronic Equipment and Facilities, Basic Theory,
and Volume 2, Grounding, Bonding, and Shielding for Electronic Equipment and
Facilities Applications, shall be installed in the floor of all spaces.  The
preferred method of placing cables and wiring is given in the BESEP for the
Raised Floors.  When raised flooring is required, it shall conform
to the requirements of NFPA 75, MIL-F-29046, Flooring, Raised: General
Specifications for, and MIL-HDBK-1008.  The flooring system shall be either a
bolted grid (stringer) or a rigid grid system, as required by the BESEP.
Finishes shall be seamless vinyl or laminated plastic.  All air supply panels
and similar inserts shall be flush with the flooring surface.  Installation
shall conform to MIL-HDBK-419, Volumes 1 and 2.  A raised floor installation
over a level permanent floor is generally preferable for flexibility of cable
access and routing; however, depending on the facility layout, a dropped or
recessed permanent floor may be used.
Roofs.  Roofs shall be constructed of noncombustible materials.
Where HEMP pulse requirements must be considered, metal roof deck is
preferred; elsewhere, precast or cast-in-place concrete is preferred. All
roof construction shall conform to the requirements of MIL-HDBK-1190, Facility
Planning and Design Guide, and MIL-HDBK-1008.
