Improvements to Building Code cover fire safety
requirements, surface water drainage and waterproofing in
bathrooms, kitchens and laundries

The latest
changes to the Building Code will improve fire safety
requirements, surface water drainage and waterproofing in
bathrooms, kitchens and laundries, says Dave Robson, Manager
of Building Performance and Engineering at MBIE.

The
changes support high density housing, will make consenting
easier, and ensure buildings are safe, healthy and
durable.

“We are going ahead with the majority of
changes proposed earlier in the year with some amendments,
after receiving mainly positive feedback through the
consultation process,” Mr Robson says.

“Gathering
sector feedback through public consultation is a vital part
of the Building Code update process. Based on the
submissions we received, we have made improvements to our
proposals, and reconsidered some aspects based on what we
heard. This is all reflected in the decision
document
.

“We will be providing a new Acceptable
Solution for the design and installation of stormwater
drainage systems, providing more options to comply with the
Building Code for surface water drainage. We are making it
easier to determine rainfall intensities for specific
locations by updating rainfall intensity maps.

“We
are also introducing a new Acceptable Solution for
waterproofing in bathrooms, kitchens and laundries by
referencing the Waterproofing Membrane Association code of
practice for Internal Wet-area Membrane
Systems.

“Following feedback from the consultation,
more work will be done around fire testing protocols for
cladding systems for 10-25 metre high buildings, and
firefighting operations.” In the meantime, MBIE has
updated the Cladding
Guidance document
released in 2019 to align with the
requirements in the Acceptable Solution and Verification
Method.

The changes were originally part of the June
2020 Building Code update, however due to COVID-19 and late
submissions, the publication date moved to November
2020.

The changes will come into effect 4 November
2021, a longer period than usual to line up with the new
delivery model.

After this update, MBIE will be moving
to annual updates of the Building Code. The next update
published will be in November 2021.

“MBIE is
committed to updating the Building Code so that it keeps
pace with innovation, current construction methods and the
needs of modern society. It provides clarity, consistency
and certainty for the whole construction sector, including
homeowners, designers, builders and building consent
authorities,” Mr Robson says. The current focus of the
Building Code update programme is to support densified
housing.
