Fire safety design resources available here:
> Mass Timber Guidance Supplement
> New Zealand commentary to the Global Design Guide
> Fire Safe Use of Wood in Buildings – Global Design Guide

PTL Structural & Fire and Gannon Fire & Risk have been engaged by the Timber Design Society (with funds from MPI) to review and update these documents, and we are currently seeking input from the industry.

Recommended Supplement to C/AS2 and C/VM2

As an interim output from the project, Timber Unlimited has consulted mass timber suppliers, industry organisations, fire engineers, FENZ, MBIE, TDS, SESOC and structural engineers through the development of the “Mass Timber Guidance Document – Recommended Supplement to C/AS2 and C/VM2”.

This will provide much-needed clarity and recommendations for designers who are designing timber and hybrid buildings. 

New Zealand Commentary to the Global Design Guide

This first draft of Commentary along with the Global Design Guide, presents information to assist building designers to meet the requirements of the New Zealand Building Code, whether by Acceptable Solutions, Verification Methods, or alternative solutions, depending on the size, use, and location of the building.

This Commentary is open for review. Please email feedback to enquiries@timberunlimited.co.nz.

Global Design Guide

Fire Safe Use of Wood – Global Design Guide was published in 2022; however, detailed commentary guidance is needed to remove uncertainty in the design and consenting of timber buildings in New Zealand.

Timber Unlimited Advanced Fire Safety Guidelines will enable fire engineering designers and approval authorities to more easily understand and follow compliance pathways within the NZ Building Code, justified by international trends and recent research results.
