PBA
Performance Based Approach (PBA)
Introduction:
UBBL 1984 by Law-
Ninth Schedule
Dimensions of Buildings and Compartments Maximum Limits of Dimensions – 4000m² (3700m² under SBO 1994 by Law) or 14000m³ (under sprinklered building)
Seventh Schedule
Maximum travel distances to exits and dead end limits shall be specified in the Seventh Schedule of By-Laws. Limits when alternative are available for shops are 45 meter (sprinklered building).
Performance Base Approach apply IF extended of compartmentation and travel distance.
Objective:
- Brief overall understanding to Bomba (JBPM) Authority.
- Fire Engineering Performance Based study on the project
- Option solution to show compliance with the prescriptive clause in UBBL 1984.
Design Solution:
Provision of engineered smoke system though CFD modeling, Evacuation study. Demonstrate that larger compartment area will not jeopardize critical life safety tenability criteria for anticipated fire loads at compartment area during fire conditions therefore occupants have safe egress.
Tenability Criteria:
- Usually required to establish the acceptability (or not) of the design.
- Measures of the time for life threatening conditions to develop.
- Tenability criteria are taken at smoke layer height of 2.5m from FFL.
- Visibility criterion-MUST be > 10m
- Temperature criterion-correspond upper layer temperature of approximately ≤200ºC
Scope of Services
The fire engineering works will address the resolution of a comprehensive
fire safety strategy to provide an appropriate level of both life safety and
property / business continuity protection. The main aspects of the design
on which we will normally advise are as follows:
Means of Escape
• Travel distances including number, location and width of exits.
• Stair sizing.
• Protection of escape routes.
• Management of evacuation including advice on phased / zoned
evacuation.
• Design of smoke management systems (if required).
• Escape provisions for people with disabilities.
Spread of Fire and Smoke
• Level of compartmentation to mitigate internal fire spread, including
the use of sprinklers and any trade-offs in design.
• Provision of measures to prevent external fire spread between
buildings.
• Assessment of the structural fire protection requirements.
Fire-Fighting Access
• Provisions for Fire Service access and fire-fighting facilities including
number and location of fire hydrants.
• Design of Smoke ventilation and clearance systems for use by the
fire brigade.
Business Continuity and Insurers Requirements
• Consideration of business continuity issues.
• Separation of insurance requirements and recommendations.
• Negotiations with insurers re: alternative solutions to meet their
aspirations.
The normal support proposal is in two stages:
Stage 1: Outline Fire Summary
The objectives of the Stage 1 works will be to provide a rapid
appraisal of the project for design team members to identify the key
fire safety issues.
The works to be carried out during Stage 1 will be:
• Review of current proposals and cost plan.
• Appreciation of operational aspirations.
• Set out key fire safety issues ("show stoppers").
• Indicate strategies to resolve 'key issues'.
• Identification of possible design changes to enhance the design.
• Identification of possible design changes to deliver cost savings.
• Identification of possible design changes to achieve business
and property protection.
• Preliminary review of structural fire protection requirements.
• Summary of proposed active fire safety systems (eg smoke
control, sprinklers and fire alarms).
• Attendance at design team meetings (see below).
• Preliminary discussions with the statutory authorities.
• Preliminary discussions with the insurers.
• Ad-hoc advice to the design team as required.
• Identify key items that will require resolution by tenants.
Stage 2: Detailed Fire Safety Strategy
The objective of the Stage 2 works will be to achieve formal
approval for the fire safety strategy. This will be achieved through
the development of a detailed Fire Safety Strategy report and the
correct implementation of the fire strategy in the design.
The works to be carried out during Stage 2 will be:
• Detailed means of escape analyses.
• Smoke development study.
• Structural fire protection calculations if required.
• Set out sprinkler strategy.
• Detail fire fighting access strategy.
• Confirm compartmentation strategy.
• Commentary on interface with existing scheme.
• Statements on property protection, business continuity and
insurance requirements.
• Confirm building flexibility with respect to possible tenancy
variations and future operations.
• Attendance at design team meetings (see below).
• Additional meetings with individual team members as required.
• Support in formal negotiations with the statutory authorities.
• Support in formal negotiations with the insurers
• Advise the design and construction teams on the implementation
of the fire strategy.
• Review design team information for compliance with fire strategy.
We have included for the use of complex smoke modelling techniques
such as Computational Fluid Dynamics (CFD) and evacuation modelling.
These comprehensive modelling techniques will be applied during the
Stage 2 works if required. However, prior to this, other less complex
modelling techniques will be used during Stage 1 to provide preliminary
results to support the design team.
