Structural Requirements. Modernization of existing structures shall
be investigated and upgraded seismically in accordance with NAVFAC P-355.
system can be modified, provided that the new loading distribution caused by
such modifications does not overload existing members. When it is determined
that the structural system will not meet the design loads, those members that
are considered inadequate should be strengthened, modified, and/or replaced.
The structural systems should be inspected; where deficiencies are noted,
maintenance and repair work should be performed.
Electrical Requirements. Lighting, power, and telephone systems
should be in accordance with the requirements of the NAVFAC DM-4 Series,
NFPA-70, and Paragraphs 4.4 and 4.5.
Reuse. Wiring and transformer capacities should be checked for
adequacy with respect to current and future load requirements and upgraded as
necessary. Equipment judged to be in safe and operable condition should be
Special Systems. Special systems requirements should be in
accordance with the NAVFAC DM-32 Series, Storage, and as outlined in
Lighting. Where lighting intensities are deficient, existing
Mechanical Requirements. The following mechanical requirements
should be observed in the modernization of existing buildings: The number of
plumbing fixtures specified in MIL-HDBK-1190 should be provided. New toilet
accessories should be provided where deficiencies exist. Plumbing should
conform to the minimum requirements set forth in the NAVFAC DM-3 Series.
Energy Conservation. In an existing building, the site (geographic
location), orientation, controls, equipment sizes, and selections are
essentially fixed. However, the values of other basic parameters such as
ventilation, infiltration, building envelope, "U" factor (walls, floor, glass,
roof), and shading can be improved and should be evaluated as accurately as
possible for energy and cost-effective improvement. The existing HVAC
equipment should be evaluated and potentially modified to comply with the
energy conservation requirements in DM-3.03. (Refer to the NAVFAC DM-3 Series
Toxic Materials. Existing building products containing asbestos or
other toxic materials should be removed in accordance with NFGS-02075, Removal
and Disposal of Asbestos Materials; OPNAVINST 5100.23B, Navy Occupational
Safety and Health Program; OSHA Standards 1910 Series; and other current
Federal and industry standards.
Fire Protection and Life Safety. Fire protection and life safety
requirements shall be in accordance with MIL-HDBK-1008 and NFPA 101.
