Planning and Concepts neering approach, methodology, software, tools, etc. The FSE would consult SCDF on the FEDB proposal before formal submission to SCDF is made. The FEDB will be assessed by our SCDF officers 2. Upon the in-principle approval of the FEDB, the FSE can proceed to prepare the Fire Safety Engineering Report (FER) which documents the results of the fire engineering study and the Operations and Maintenance (O&M) Manual which summarizes all the performance-based issues for the building owner to address in planning his fire protection maintenance regime. After the preparation of the above reports by the FSE, an independent peer reviewer, who is also a registered FSE with SCDF, would be engaged to assess the above reports and ensure that the PB solution is incorporated in the Building and M&E Plans. The peer reviewer will then prepare a report for his assessment in a Peer Reviewer’s Report. The project Qualified Person (QP) is required to collate all the above reports for plan submission to SCDF. All performancebased plan submissions are audited by SCDF. Upon completion of the fire safety works, the owner is required to engage a Registered Inspector (RI) who must be a FSE to inspect the performance-based aspect of the fire safety works. This is over and above the RI (Architecture) and RI (M&E) 3 that are required for most new buildings. The need for the SFEG The need for drafting the SFEG is discussed below. Extensive consultation As highlighted in the earlier paragraph, the set of international fire safety guidelines currently adopted are generic and lack critical design information. This results in extensive consultation sessions where the design parameters and methodologies are discussed. The requirements are verbalised during the consultation sessions and documented in the individual fire safety reports. These requirements however are not available in any common reference documents that FSEs can refer to. Hence, these design parameters and methodologies need to be documented to reduce consultation with SCDF and to improve transparency and consistency. Modern buildings like the Gardens by the Bay are challenges for Fire Safety Engineers. The Flower Dome (left) is the world‘s largest column-less glasshouse. Source: www.landezine.com To provide guidance FSEs that specialise in certain type of projects (e.g. industrial projects) would also benefit if they take on PB projects of other nature/purpose groups as there would be a set of guidelines that provides critical design input parameters. Maturity of the PB fire safety approach in Singapore When performance-based fire safety design was first introduced to the industry in July 2004, FSEs had adopted the approaches found in international fire engineering guidelines as templates in drafting their reports and presenting their analysis/results. The PB fire safety approach here has since matured and now has the depth and capacity to draft our own fire safety engineering guidelines to better reflect the local PB fire safety landscape. Clarity on critical design parameters The SFEG documents the basic design fundamentals and design input and output parameters when embarking on a PB fire safety engineering design approach. FSEs will therefore be informed of what assumptions/inputs can and cannot be adopted in the design process and what output results to be shown in the FER. This includes design fire scenarios, determination of fire sizes, soot yield values, smoke temperature readings, etc. Stakeholders’ involvement SCDF did not embark on this journey alone. A PB Code Review Committee was formed in May 2013 to develop the SFEG. This committee was chaired by the Director of the Fire Safety and Shelter Department (FSSD) and comprises FSSD officers, FSEs representing the various institutions 4 and active FSEs participating in their individual capacity. Guiding principles in drafting the SFEG The principal considerations adopted when drafting Singapore’s PB guidelines were as follows: The SFEG should be aligned with international best practices. Methodologies to be adopted to address deviations should be congruent with existing international fire safety engineering guidelines. While PB fire safety engineering design can generally be classified into deterministic or probabilistic analysis of fire scenarios, the FeuerTRUTZ digital Subscribe to the free FeuerTRUTZ Magazine ePaper at www.feuertrutz.com/magazine FeuerTRUTZ International 2.2016 11
