- SNZ HB 3604 Handbook to NZS 3604:2011 – available now
- Advisory Note issued for NZS 3604:2011 and SNZ HB 3604:2011
Standards New Zealand recently published SNZ HB 3604:2011 Timber-framed buildings: Selected extracts from NZS 3604:2011. SNZ HB 3604 provides users with a collection of figures and tables extracted from NZS 3604:2011 that are commonly used on-site. The Handbook directs users to the appropriate section of the Standard for full information.
During the development of the Standard, NZS 3604:2011, the need for a durable product containing selected extracts from the Standard to use as a reference guide on-site was identified. Standards New Zealand undertook four consultation meetings with different user groups on the range of content they required and tested formats for the Handbook in mid-2010.
The SNZ HB 3604 committee began work on the Handbook once the NZS 3604 Standard content had been finalised. The committee included nominated representatives from Architectural Designers New Zealand Inc., Building Officials' Institute of New Zealand, Certified Builders' Association of New Zealand Inc., New Zealand Institute of Architects, and Registered Master Builders' Federation. The feedback from the consultation meetings was used by the committee.
The Handbook has been designed as an on-site reference guide for timber-framed buildings not requiring specific engineering design, up to a maximum of three storeys in height. It is laid out in four sections based on the construction sequence for a timber-framed building. To ensure that the Handbook aligns with NZS 3604, the collection of figures and tables are numbered identically and colour coding of the figures and tables replicates that of the Standard.
The development committee advises the Handbook must not be used as a substitute for the full Standard, NZS 3604:2011. Users of SNZ HB 3604 should always refer to the full Standard when they require detailed and complete information. On-site building consent requirements of the Building Consent Authority (BCA) take precedence over the guidance in SNZ HB 3604.
With a polypropylene cover, the sturdy binder and laminated pages are designed to provide as much durability for on-site use as possible. SNZ HB 3604 is slightly larger than A5 in size and weighs approximately 1.2kg.
