Expediting the PB Process

Expediting the PB Process
Auto-Approval of INDUSTRIAL FEDBs.
![Page 9: 2nd Fire Safety Engineer (FSE) - SCDF Home Page · 2nd Fire Safety Engineer (FSE) Dialogue Session Friday 26th Oct 2018 2:30 pm to 5:00 pm SCDF HQ City Campus Level 3 Lecture Room](https://reader034.fdocuments.us/reader034/viewer/2022050120/5f5053342d4cde087306227e/html5/thumbnails/9.jpg)
Why the change now ?
I. Move towards self-regulation (similar to prescriptive compliance)II. Experienced and mature FSE fraternity.III. FEDB quality generally achieve minimum standards.IV. Little or no changes at the FER stage.

Why only Industrial FEDBs ?
I. SFEG clearly documents the PB issues and methodology.II. Low occupant loading.III. Generally no public access.IV. Issues are standard.
![Page 13: 2nd Fire Safety Engineer (FSE) - SCDF Home Page · 2nd Fire Safety Engineer (FSE) Dialogue Session Friday 26th Oct 2018 2:30 pm to 5:00 pm SCDF HQ City Campus Level 3 Lecture Room](https://reader034.fdocuments.us/reader034/viewer/2022050120/5f5053342d4cde087306227e/html5/thumbnails/13.jpg)
Effective date
a) Effective in 1st Jan 2019. (Pending final internal approvals)b) Review of Industrial FEDBs
1. From 1st Jan 2019, FSEs can still request for FEDB review with justifications. First page of report to clearly state request with justifications.
2. Once request for FEDB review is lodged, cannot withdraw request.3. FEDBs with F.E.D. proposed as acceptance criteria will be subjected to review.
FSE to declare “Fractional Effective Dose is not adopted as an acceptance criteria”
4. SCDF can still choose to review any Industrial FEDBs.
![Page 14: 2nd Fire Safety Engineer (FSE) - SCDF Home Page · 2nd Fire Safety Engineer (FSE) Dialogue Session Friday 26th Oct 2018 2:30 pm to 5:00 pm SCDF HQ City Campus Level 3 Lecture Room](https://reader034.fdocuments.us/reader034/viewer/2022050120/5f5053342d4cde087306227e/html5/thumbnails/14.jpg)
From 1st Jan 2019 -> 1st page of all Industrial FEDB
a) FSE to declare “Fractional Effective Dose is not adopted as an acceptance criteria”b) Request for FEDB review with justifications (if that is FSE’s request)
![Page 15: 2nd Fire Safety Engineer (FSE) - SCDF Home Page · 2nd Fire Safety Engineer (FSE) Dialogue Session Friday 26th Oct 2018 2:30 pm to 5:00 pm SCDF HQ City Campus Level 3 Lecture Room](https://reader034.fdocuments.us/reader034/viewer/2022050120/5f5053342d4cde087306227e/html5/thumbnails/15.jpg)
Benefits for the PB Process
I. Faster approvals for industrial FEDB.II. Shorter processing time for all projects.
1. More time for review2. Shorter queues

Rest of the FEDBs
Review as per current situation.
All FERs
Review as per current situation.

1. Could the guideline of CFD smoke simulation for residential corridor (excessivedistance for cross ventilation in SSL/FFL typically) be consolidated and published inwebsite for sharing among all FSEs, if this has not done so.
The guidelines for the above are published in the FSE dialogue slides that can bedownloaded from the SCDF website :
[Fire Safety >> Plans and Consultation >> Performance-Based Approach to Fire SafetyDesign >> Fire Safety Engineers (FSE) Dialogue Session].
Queries Raised
![Page 20: 2nd Fire Safety Engineer (FSE) - SCDF Home Page · 2nd Fire Safety Engineer (FSE) Dialogue Session Friday 26th Oct 2018 2:30 pm to 5:00 pm SCDF HQ City Campus Level 3 Lecture Room](https://reader034.fdocuments.us/reader034/viewer/2022050120/5f5053342d4cde087306227e/html5/thumbnails/20.jpg)
2. To carry out CFD simulation for resi corridor, if resi unit has two doors, need to open both doors or choose to open only one door for smoke to plume into corridor.
Query is project specific (Case by case) . FSE advised to come in for consultation with study proposals after assessing the fire and life safety risks.

3. To carry out CFD simulation for resi corridor, if resi unit is a marionette (or duplex) with upper level, but only one entrance on lower level, where to place the fire in CFD simulation, ie upper level or lower level?
Query is project specific (Case by case) . FSE advised to come in for consultation with study proposals after assessing the fire and life safety risks.

4. If Waiver with Engineering Justification for singular non-compliance ofprescriptive fire code, eg. Smoke reservoir length, or permissible mass flow rate, or traveldistance increased by 10% is still permitted by SCDF, without the need for full PBframework.
Waiver with engineering justification (PB waiver) allowed only:
a) For clauses in Circular (Dec 2015) and/orb) If prescriptive WVR Decision specifies that WVR with additional fire engineering
study is needed.

The waiver description/issues need
to be separated as they areprocessed individually. 5 paymentsmade.
Will be rejected even if QP/FSEsubsequently makes 4 additionalpayments into WVR Ref number.
Correct number ofissues is necessaryfor processing.

Addressing deviations in multiple blocks/floors.
Where the deviations (Eg : No part of the floor area of the corridor shall be at adistance of more than 13m from any ventilation openings) is applicable to differentblock/floors with similar layout, FSE cannot model most onerous layout as arepresentative of the others.
Each block/floor is reviewed individually and would require its own assessment as itis a unique design.
Adopting fire engineering results for other blocks/floors is allowed only if theblocks/floors are exactly identical. FSE would need to declare that they are exactlyidentical.
