SR24 Design and cost implications of DZ 4203:1989 (2007)

The current loadings code (NZS 4203:1984) is being rewritten to reflect advances in research and knowledge in recent years. The latest proposed draft of the revised code (DZ 4203:1989) was circulated for comment, and a SANZ Review Committee reviewed these comments in June 1989.

In an attempt to ascertain the impact on the building industry of the proposed changes in the draft code, a number of consultants were commissioned to redesign projects that have been designed in accordance with NZS 4203:1984.

The findings of these consultants have been collated to form the basis of this. report. The effect of DZ 4203:1989 on the designs of different types of structures is discussed together with indications of the approximate cost differences between structures designed to DZ 4203:1989 and NZS 4203:1984 and rough orders of cost established.
