MBIE amended four Verification Methods and seven Acceptable Solutions of the following NZ Building Code clauses:
B1 - Structure, B2 - Durability, E2 - External Moisture, G12 - Water Supplies and G13 - Foul Water.

On 30 November 2018 MBIE released new Amendments to the following Verification Methods and Acceptable Solutions:

Amendment 17 to B1/VM1 includes:

Both these new documents expand on information currently available with the former providing design options for a wider range of composite structures and the latter enabling more designers to specify corrosion protection systems.  B1/VM1 also now references the latest version of the wind loading Standard.

 Amendment 10 to B2/AS1 includes:

This amendment provides clarity on steel protection measures avoiding the need to justify alternative solutions proposals.

 Amendment 8 to E2/VM1 and E2/AS1 includes:

Both the Verification Method and Acceptable Solution have been amended to include Extra High wind zones.  Amendments have been made to the Verification Method to clarify the testing requirements for ensuring adequate weathertightness performance of claddings.  The revised testing requirements will apply to all new testing; current test certificates will remain valid.

Amendment 11 to G12/VM1 and G12/AS1 includes:

This means that common stainless steel pipework installation will no longer have to be treated as an alternative solution proposal.

Amendment 11 to G12/VM1 and G12/AS2 includes:

This means that common stainless steel pipework installation will no longer have to be treated as an alternative solution proposal.

Amendment 7 to G13/AS1, G13/VM2, G13/AS2 and G13/AS3 includes:

Use of these provisions will no longer need to be treated as alternative solution proposals.

The amendments ensure that the latest performance requirements are provided as a means of compliance.

The previous Acceptable Solutions and Verification Methods will continue to comply until 31 March 2019 inclusive.  If used from 1 April 2019, they must be considered an alternative solution proposal.

Notification date: 4 December 2018
