 9.2.2
NAVFAC DMs, MIL-HDBKs, P-Pubs and NAVAIR Technical Manuals
DMs, MIL-HDBKs, P-Pubs and NAVAIR Technical Manuals contain criteria relative
to specific design disciplines, facilities, systems, equipment or operational
procedures. These documents form the backbone of Navy criteria and are the
most commonly used criteria for Navy projects. In some cases these manuals
are "tri-service", i.e., they have been adopted for use by the Navy, Army and
Air Force.
9.2.3
NAVFAC DPLs
Design Policy Letters (DPLs) are essentially amendments to DMs, MIL-HDBKs, or
other Navy criteria. They are issued by Naval Facilities Engineering Command
(NAVFAC) Headquarters to immediately implement new or revised design policy
until such time as the appropriate criteria can be officially amended.
9.2.4
NAVFAC Guide Specification (NFGS) Sections
NFGS sections are master text specification sections which are edited by the
A/E to suit a particular project. The edited versions prepared by the A/E
form the project specification. NFGS sections are arranged in Construction
Specifications Institute (CSI) 16 Division, 3 part format. Each specification
section contains technical notes ("criteria notes") which explain how to
properly edit the section to suit the requirements of a project. There is
currently a library of approximately 400 NFGS sections available. (See the
chapter titled "Preparation of Specifications" for more information).
9.2.5
Standard Designs (Standard Drawings and Standard Specifications)
Standard Drawings are detailed working drawings of Navy-unique facilities,
specifically magazines, moorings, camels, markers or buoys, unabated power
check facilities, portal crane accessories, aircraft wheel chock assemblies,
standard fittings for waterfront structures and brows and platforms. These
drawings form a part of the construction documents requiring that the A/E
prepare supplemental drawings for adapting the facility to the site. Their
use "as is" is mandatory for magazines, whereas all others may be modified as
necessary to meet specific requirements.
Standard specifications are facility specifications that contain sections
covering unique construction (camels, magazines and unabated power check
facilities) that are incorporated verbatim by the A/E into the project
specification. These sections are then supplemented by NFGS sections edited
by the A/E to cover conventional or project-unique features such as concrete
or sitework.
Site adaptation of standard designs, in general, consists of siting the
facility and designing all exterior features (paving, drainage, utilities,
etc.), modifying the foundation structure to suit the site, seismic
considerations and, if applicable, necessary mechanical changes to suit
climatic conditions existing at the site. If other changes in the standard
designs are contemplated, such changes will be defined in the Appendix "A".
It is not the responsibility of the A/E to review or check the standard
designs furnished for site adaptation. However, if errors in the drawings or
specifications are discovered or if the design or functional layout appears
unworkable for site adaptation, the matter shall be brought to the attention
of the DM for resolution.
9.2.6
Definitive Drawings
Definitive drawings are issued by NAVFAC for buildings and structures for
which there will be a repetitive need in future Military Construction
