Have your say on the new acceptable solution

The new acceptable solution, E2/AS3 for the weathertightness of concrete and concrete masonry buildings, was introduced on 1 August 2011 and is now being reviewed by MBIE.

It references the CCANZ’s Code of Practice for Weathertight Concrete and Concrete Masonry Construction, which covers the weathertightness of the building envelope for concrete slabs on the ground, concrete walls and associated methods of insulation, concrete flat roofs and decks, and concrete to timber construction junctions.

To aid planners and builders, the Code of Practice follows the same format as existing weathertightness solutions, but offers larger detail drawings following the text. According to CCANZ chief executive Rob Gaimster, it also allows builders, designers and clients to choose from a wider range of building materials.

MBIE is now reviewing the uptake of this solution and would like to hear from licensed building practitioners and members of the industry about how it is being implemented. MBIE is particularly interested to know if there are any commonly used weathertightness details that are missing or have been overlooked, or any ideas or suggestions to help inform changes that should be made.

Any feedback should be emailed to nick.locke@dbh.govt.nz or admin@ccanz.org.nz. The formal public consultation, which will give people an opportunity to comment on proposed changes, will take place later in the year.
