required for a facility beyond that provided by minimum standards, additional
requirements to those included in UFC 4-010-01 may be necessary.
2-2.3.1 Structural Design. If the minimum standards are applicable, conventional
construction will be adequate to minimize the risk of mass casualties from a terrorist
attack if minimum standoffs distances are achieved. However, additional structural
considerations may be necessary to prevent progressive collapse.
2-2.3.2 Progressive Collapse Prevention. UFC 4-010-01 defines the minimum
requirements for the progressive collapse prevention of buildings. UFC 4-023-03,
Design of Buildings to Resist Progressive Collapse, provides additional guidance on
application of the progressive collapse avoidance requirements of UFC 4-010-01.
2-2.3.3 Structural Hardening to Resist Conventional Weapons Effects. UFC 3-
340-01, Design and Analysis of Hardened Structures to resist Conventional Weapons
Effects, must be used if it is necessary to structurally harden a building to resist a
potential conventional explosive terrorist attack. It is highly recommended that when
structural hardening to resist the effects of blast loading is required, the structural
engineer present evidence to the NAVFAC FEC / EFD / EFA of having previously
completed similar designs.
TM5-1300/NAVFAC P-397/AFR 88-22, Structures to Resist the Effects of Accidental
Explosives (AAE) operations in order to protect personnel and material from the effects
of an accidental explosion.
2-2.4
Extraordinary Events. When specifically required, strength and stability
shall be checked to ensure that structures are capable of withstanding the effects of
extraordinary (i.e. low probability) events such as fires, explosions and vehicular impact.
2-2.5
individual members must be in accordance with the fire-resistive requirements as
referenced in UFC 1-200-01.
2-2.6
Proprietary materials. Design values for proprietary materials shall be
obtained from International Code Council Evaluation Services (ICC-ES) Evaluation
Reports. Proprietary materials shall not be used without prior approval of the NAVFAC
FEC / EFD / EFA.
2-3
SYSTEMS REQUIREMENTS.
2-3.1
General.
2-3.1.1 Requirements contained herein that represent construction requirements
must be included on the construction documents. As a minimum, construction
documents include drawings and abbreviated format prescriptive specifications for
design - build projects and drawings and UFGS specifications for design-bid-build
projects
