Regardless, consider the incorporation of accessibility features into the
design of the facility. Such features include:
Accessible toilets on the ground floor for visitors.
Accessible entrances.
Other items that do not add significant expense to the project.
See also paragraph 2-8 and Chapter 3 for further discussion regarding
hangar accessibility requirements.

FUNCTIONAL ANALYSIS CONCEPT DESIGN (FACD). The design of
the hangar can be enhanced by the incorporation of a Functional Analysis Concept
Design or FACD. The FACD brings all of the design team (Design Agent, Activity,
Owners, A/E) and other interested parties to participate in project development and the
design process. The FACD generally takes place over a 10-day period and results in
the conceptual design of the project being approved by all participants of the FACD.
For guidance on this process, contact the NAVFAC Engineering Innovation and Criteria
Office (EICO.)

DESIGN ISSUES. A list of issues in questionnaire format is attached as
Appendix B to provide assistance to the A/E and the Activity in the planning and design
of the hangar.

construction to be used. Generally, hangars constructed around a jet operations base
are going to have much higher noise thresholds than a base where mostly helicopters
and propeller driven aircraft are operated. The selection of the materials used in the
exterior envelope may be determined due to the noise levels at the base. The selection
of heavier materials that would be helpful in reducing noise transmission into the
building will impact the cost of the facility. Consider performing an acoustical study to
evaluate the construction requirements that will be appropriate for the base.
1-15
PROTECTED DISTRIBUTION SYSTEMS. Evaluate the requirements for
a Protected Distribution System (PDS) at the early stages of design. The installation of
SIPRNET and other types of secure communications systems have an impact on the
building layout, construction of partitions, hardware requirements and other items. The
activity must identify their requirements and coordinate with the appropriate
publications.
1-16
TELEPHONE AND OTHER COMMUNICATION SYSTEMS. Coordinate
the communications requirements with the activity. For Navy and Marine Corps
facilities coordinate the space with requirements with the Navy Marine Corps Intranet
(NMCI) Standard Construction Practices. NMCI provides documentation to establish
equipment and space requirements for each facility. See UFC 3-580-10, Design: Navy
