Publication | Amendment |
Bulletin 350 Sizing gutters | The maximum permitted area of roof (in m2) discharging to a given downpipe size given in Table 3 is significantly different from that specified in E1/AS1. This may result in the downpipe being overloaded in maximum rainfall conditions. Please delete Table 3 and replace with Table 5 of E1/AS1. Figure 3 of E1/AS1 may also be used to assist in sizing downpipes for given flow rates. |
Bulletin 457 Ventilation of enclosed subfloor spaces | Note that, while E2/AS1 only requires ventilation under suspended timber floors, BRANZ recommends as good practice that ventilation is also designed for under suspended concrete slab floors. |

Bulletin 495 Stair design | Figure 6(b) - The tread dimension should read 266 to give a 35º pitchline. Figure 6(c) - The pitchline for the dimensions given should be 31.85º, and not 33.1º as noted. |
Bulletin 498 Preparation for concrete floor slabs | Paragraph 12.0.2 of this bulletin refers to shrinkage control joints and states that: "Mesh reinforcing to the slab must stop each side of the joint." This is not correct - stopping the reinforcement each side of the joint creates a ‘free joint', not a shrinkage control joint. The mesh in a reinforced concrete slab-on-ground should not be cut when cutting/forming a shrinkage control joint. See Build 84 Oct/Nov 2004 p35 for more information. |
Bulletin 515 Measuring moisture in timber and concrete | In the first issue of this bulletin, the corrected moisture content percentages for boron-treated radiata pine given in Table 2 were wrong. The correct figures are: |
