4.1
General. The function of the FPUS central facilities is to
provide a common source of supply for aircraft utilities and to provide
protective shelter for the maintenance and repair of the central equipment.
Emphasis shall be placed on siting to permit FPUS planning as described in
par. 2.2.1. Refer to MIL-HDBK-1028/1, Aircraft Maintenance Facilities, for
criteria and requirements.
4.2
Building. The building shall be a prefabricated metal building
of modular design. For consideration of prefabricated structures, refer to
NAVFAC DM-1 series, Architecture. The materials selected shall conform to
25-year economic life considerations for an industrial type building. The
design shall include requirements for fire protection. In specific site
locations where seismic forces are encountered, selection of materials and
designs shall be in accordance with NAVFAC P-355, Seismic Design for
Buildings.
4.2.1
Restrictions on the Use of Aluminum. Aluminum roofing and siding
shall not be specified for structures located on or near the sea coast

free from salt deposits or incrustation due to onshore winds and salt-laden
atmosphere. Consideration shall be given to corrosion of aluminum on
interior building surfaces. Aluminum surfaces shall be isolated from
incompatible metals or material preservatives and masonry or concrete
surfaces by treating with a heavy coat of alkali-resistant paint or by
other approved means.
4.2.2
Architectural Requirements. Space allocations shall provide for
flexible and economical equipment additions and an orderly expansion of the
building. Space configuration shall be as required for the proper
maintenance of the equipment to be installed and shall allow the
installation of a monorail and traveling hoist to be installed under the
roof framing in the approximate center of the building. The building design
shall provide toilet facilities and heating, ventilating, and lighting
equipment necessary for a proper working environment.
4.2.2.1
