NOTE: NFPA 101, Life Safety Code and the SFPE Engineering
Guide to Performance-Based Fire Protection Analysis and Design of Buildings
provide guidance regarding the development and evaluation of appropriate
performance criteria.
D-3.1.6
Design Fire Scenarios. Document complete descriptions of the
reasoning, intent, and details of all required and stakeholder defined fire
scenarios. Use realistic and accurate fire scenarios, with respect to all fire
elements, including initial fire location, early rate of growth in fire severity, and
smoke generation. Indicate in the description of the fire scenarios all applicable
data, characteristics and assumptions, which must remain consistent between all
fire scenarios. Ensure the omission of certain details will not reduce the reality of
the proposed design fire scenario. The design engineer must justify any design
fire scenario data that is omitted or cannot be considered by available evaluation
methods, and this justification must be noted and approved by the authority
having jurisdiction.
D-3.1.7
Technical References and Resources [Methods of Evaluation].
Thoroughly document all technical references, including methodologies, data and
sources. Identify the scientific basis of each engineering calculation method or
model. Develop, review and validate these methods using a consensus, peer-
review process, or obtain from resource publications. Where the chosen
methods do not permit the incorporation of all data or do not accurately address
the incorporation of the data, perform a sensitivity analysis for any design,
performance criteria, or fire scenario data that cannot be included or used in the
chosen methods. Address all degrees of conservatism and factors of safety, and
clearly identify the limitations of the calculation methods. Any method whose
outcome is significantly altered by the omission of trial design or fire scenario
details will not be approved, and the omission of critical data is prohibited. The
use of proprietary and non-peer reviewed data or source is not permitted. The
authority having jurisdiction must approve the assessment methods, data, and
sources, and confirm the validity of all technical references and resources prior to
the design evaluation. Provide the technical reviewer, upon request, any
technical references or resources.
D-3.1.7.1
The performance criteria must be capable of being proved or
measured using existing engineering tools and methods.
D-3.1.8
Trial Designs. Identify and document the general details, including
the proposed construction, systems, and protection methods. Include in the
documentation the safety factors associated with each trial design, as agreed
upon by the stakeholders. Clearly identify the impact of the safety factors so that
a reasonable decision can be made as to whether their level is appropriate and
sufficient. State any retained prescriptive requirements. Where the interaction of
emergency response personnel is a designed protection method, accurately
identify and confirm the impact and responsibility of the emergency personnel.
