Summary

The Ministry of Business, Innovation and Employment (MBIE) is proposing to:

  • update Verification Method for B1 Structure (B1/VM1) to cite the latest version of NZS 3101:2006 Concrete Structures Standard : Part 1–The Design of Concrete Structures, (ie Amendment 3)
  • update Verification Method for B1 Structure (B1/VM1) to replace sections of NZS 3404.1:1997 Steel Structures Standard to reflect current practice for steel fabrication and construction
  • ban the use of the loop bar (also known as ‘pigtail’) connection detail associated with the support of precast concrete flange-hung double-tee flooring units.

The proposed amendments are part of MBIE’s response to the investigation into the performance of Statistics House in the 14 November 2016 Hurunui/Kaikōura earthquakes and recommendations from the Canterbury Earthquakes Royal Commission.

Modifications to the referencing of NZS 3404.1:1997 are not related to the Statistics House investigation, but are a timely update that will ensure B1/VM1 remains relevant to the steel industry.
