Australian Fire Engineering Guidelines abcb.gov.au Page 42 designs. A necessary precursor is for the PBDB team to determine where the trial designs do not meet the relevant DTS Provisions. This will identify the issues that need to be addressed in the analysis of the trial design (see 2.3). In cases where there are no DTS Provisions, the relevant Performance Requirements need to be identified directly (Section 2.2.7.2), and the determination of non-compliance issues (Section 2.2.7.1) omitted. It is important that the FE clearly identifies whether the trial design is being evaluated in terms of equivalence to the DTS Provisions, or according to the Performance Requirements (see Section 2.2.7.2). 2.2.7.1 DTS departures For most structures, the majority of the design adopts the DTS Provisions. Each DTS departure needs to be identified, assessed and documented by comparing the trial designs with the relevant provisions. The FE may be involved in assisting in identifying the fire safety related DTS departures, but must have access to adequate information to do so. The building surveyor and appropriate authority will also need to be involved. As more DTS Provisions are adopted, the scope of the fire engineering evaluation will generally decrease. This is because the analysis is limited to addressing the DTS departures. 2.2.7.2 Performance Requirements The determination of the Performance Requirements is based upon the identified DTS departures, and the required general non-regulatory objectives (Section It is important to note that a single DTS departure may relate to more than one Performance Requirement . In addition, the departure and Performance Requirements may not be in the same section of the NCC. |
