Planning and Concepts Author Nicholas Lee Nicholas obtained a Master in Fire Safety Engineering from the University of Western Sydney. He worked for Arup Singapore as a fire safety consultant from 2007 to 2011 and became a Registered Fire Safety Engineer. He now is a Senior Consultant at Singapore Civil Defence Force. As part of the Authority Having Jurisdiction, his main role is to review design proposals by Fire Safety Engineers (FSE) who are submitting projects under the Performance Based (PB) framework. fire safety provisions that form part of the PB fire safety engineering design that should be included in the building plan submissions. This ensures that the design proposed by the FSE is communicated to the QPs and that these details are documented accordingly in the building plans that are submitted. The SFEG also serves as a reference for SCDF officers who are newly assigned to undertake performance-based fire safety engineering responsibility. This would shorten the induction time as the new officer would require less guidance to actively and confidently Conclusion The SFEG is a crucial reference document that will provide greater clarity at the FEDB stage by specifying acceptance criteria and input parameters that can be adopted for most performance-based designs. This facilitates the role of all relevant parties i.e. FSEs in preparing the PB fire safety plans, peer reviewers in checking the plans and SCDF in approving the plans, and taken together, leads to faster approval of PB fire safety plans. ■ Marina Bay Sands Integrated Resort features three cascading hotel towers topped by an extraordinary sky park park, a lotusinspired museum, retail stores and a casino. deviations addressed in the performancebased that the building owner must take note of in future additions and alterations to the building Peer Reviewer: Due to the complexity of fire safety issues involved, an independent 3rd party checker (also a registered FSE) is required to review all performance based projects. The SFEG stipulates the role of the peer reviewer and the sensitivity studies he/ she must carry out. Registered Inspector (R.I.): In addition to the R.I. (Architecture) and R.I. (M&E), all performance-based projects would require a R.I. (FSE) at the Temporary Fire Permit (TFP) and/or Fire Safety Certificate (FSC) stage. His focus would be on the performance whether or not all the performance based provisions operate as specified. Part 2 – Method of assessment for common deviations This section discusses the recommended methods of assessment for common deviations. assess the deviations which SCDF would consider based on the merits of the case. The list of common deviations below is not exhaustive and would be updated as and when other common deviations comes to fore. The list of common deviations from the prescribed requirements are: Enlarged smoke reservoir size Enlarged fire compartments Extended 2-way travel distance or excessive occupant loading Source: www.bhmpics.com studies and specifies the limitations based aspects of the design and FSEs may propose other methods to Internal discharge of exit staircases Insufficient set-back distances to prevent fire spread between buildings. Reduced fire-resistance rating to element of structures Benefits of the SFEG With greater clarity and transparency, FSEs would have more certainty at the conceptual design stage of the project and this would lead to faster plans preparation and reduce the number of consultations needed. The SFEG can be used by both new and existing FSEs as a guide on (i) fundamental design assumptions/parameters for a performance based analysis and (ii) methodologies on how common deviations are justified. If the FSE is appointed as a peer reviewer, this role as the independent checker is also more clearly defined as the SFEG specifies the scope of the peer reviewer study, the stages of peer reviewer involvement and the modelling required for sensitivity analysis. The building industry can also rely on the SFEG at the conceptual design stage to better appreciate design limitations, especially if there are many deviations from the fire code. The SFEG also lists down the critical engage FSEs. FeuerTRUTZ International 2.2016 13
