DeltaFireXTM Car Port System Revision 1-4 20 (a) Two or more sides (making up at least one third of the awning perimeter) shall be “open” in accordance with NCC 9.2.8 (b); that is the roof covering shall be more than 500 mm from another building or allotment boundary on at least two sides without enclosing these sides with a wall, privacy screen, vehicle access door or the like within 500mm of the edge of the roof covering. A boundary along a road or public space such as parklands, lakes, rivers and the like (where the construction of buildings is unlikely) may be considered open regardless of proximity to the boundary subject to no vertical obstruction (wall, privacy screen, vehicle access door or the like) within 500 mm of the edge of the roof covering. (b) All components used in the awning construction shall be compliant with Section 3. The components shall not be modified except with the written authorisation of the manufacturer and SOTERA. (c) The awning structure shall not provide direct vertical support to any part of the adjacent Class 1 building. (d) The DeltaFireXTM car port shall consist solely of the following: (i) DeltaTrim-MW and DeltaOrb-MW panels (ii) Steel fixtures, gutters and the like (iii) Steel columns, beams, purlins and the like (iv) Metallic flashing (e) As the DeltaTrim-MW and DeltaOrb-MW sandwich panels used in the DeltaFireXTM car port system constitutes bonded laminates, the following restrictions shall apply to the DeltaTrim-MW and DeltaOrb-MW sandwich panels: (i) Each lamina shall be non-combustible. For clarity this includes low carbon steel (see AS1530.1 test in Section A.2) or mineral wool (see AS1530.1 test in Section A.1). As permitted under Section 3.3.2, low carbon steel from any manufacturer may be used and the steel may include a surface finish not exceeding 1 mm thickness with a spread of flame index no greater than 0. (ii) Each adhesive layer may not exceed 1 mm in thickness and the total combined thickness of adhesive layers may not exceed 2 mm. (iii) The spread of flame index and the smoke developed index of the bonded laminated material as a whole shall not exceed 0 and 3 respectively (refer to AS1530.3 test certificates given in Section Appendix B). 4.5 Methodology The method of assessment is qualitative to justify the risk and mitigate the hazard as identified in Sections 4.2.1 and 4.2.2. Performance requirements are addressed comparatively in accordance with BCA A2G2(1)(b) and A2G2(2)(d). 4.6 Acceptability Criteria It shall be demonstrated that the DeltaFireXTM car port system is equivalent to a DtS open car port in accordance with NCC Clause 9.2.8. 4.7 Assessment NCC H3D2 (1)permits that a bonded laminate, although combustible, may be used wherever a non- combustible materials is required subject to:
