2.1 
General 
SOTERA has been engaged to carry out fire engineering assessment of the proposed performance 
solution for the project:   
Client: 
Delta Panels Pty Ltd 
Project Title: 
Delta MW and EPS-FR Panel Awning and Patio System 
The following Fire Engineering Assessment has been conducted in order to address issues of variation 
from the Deemed-to-Satisfy (DtS) provisions of the National Construction Code 2022 Housing Provisions 
Standard & Volume 2 (ABCB 2022); hereafter referred to simply as the NCC. The fire engineering 
evaluation has been carried out in accordance with the methodologies defined in the International Fire 
Engineering Guidelines (IFEG 2005). This assessment considers the performance solution to show 
compliance with the performance requirements of the NCC. The evaluation methodology was based on 
direct compliance with performance requirements and/or equivalence to the deemed-to-satisfy provisions 
of the NCC as allowed under Part A2G1. This is supported by qualitative and quantitative evaluation 
analyses as allowed under Part A2G2 of the NCC.

Summary of Developments in Fire Engineering Report 
Rev 1-4: This report has been updated to reflect the new version of the NCC, NCC 2022 which 
supersedes the outgoing NCC 2019 Amendment 1. The report is updated with regards to the applicable 
NCC 2022 clauses and performance requirements throughout.    
Rev 1-3: Following further comments received from CertMark, the report has been updated to incorporate 
minor wording changes and to remove reference to the concession provided under NCC 3.7.1.1(e). 
Rev 1-2: This report has been updated following CertMark Technical Assessment of DeltaTrim-MW & 
DeltaOrb-MW Panels issue 1.0 dated 24/03/2022.  
Main updates include: 
• 
Reference to the AS1530.1 test for low carbon steel has been added to Section 2.4. 
• 
Section 3.3.2 has been updated to reference the AS1530.1 test for low carbon steel given in Section 
C.2 and extrapolate these results to any low carbon steel.  
• 
Section 4.4(j)(d)(i) has been updated to clarify that low carbon steel is permissible for use as a lamina 
in the DeltaOrbTM MW or DeltaTrimTM MW panels with reference to the AS1530.1 test for low carbon 
steel given in Section C.2.  
• 
Description labels in Figure 3-1 has been updated to reference the specific delta system depicted.  
• 
Section 1.3 has been updated accordingly. 
• 
Section 4.9(y) and (z) has been updated to clarify the core material of each system referenced (i.e. 
MW or EPS-FR). 
Rev 1-1: Following review by the client, the following changes have been made: 
• 
Bottom skin thickness for mineral wool panels has been changed from 0.60 mm to 0.55 mm 
throughout, consistent with fire test data given in Section D.7. Specifications given in Appendix E 
have been updated. 
• 
Top skin thickness has been changed from 0.5 mm to 0.42 mm throughout consistent with fire test 
data given in Section D.5. 
Rev 1-0: This report aims to inform stakeholders to facilitate agreement on performance solutions. 
Information and agreement is sought on matters including: critical building and occupant characteristics,
