Engineering check for an NCC 2025 Performance Solution (A2G2) against Volume One F1P1(2) or Volume Two H2P1(3)(a); compared with AS/NZS 3500.3:2025 Figure 3.5.5 (F1D3, H2D6(1)(a))
Under NCC 2025 the Deemed-to-Satisfy method for an eaves gutter is AS/NZS 3500.3 Figure 3.5.5 (Volume One F1D3, Volume Two H2D6(1)(a)); this analysis supports a Performance Solution under A2G2, assessed against Performance Requirement F1P1 for Class 2 to 9 buildings or H2P1 for Class 1 and 10.
An engineering check, not the Standard's deemed-to-satisfy method. Use it to understand a design or to support a Performance Solution under NCC 2025 A2G2.
