1. 80% of timber used during construction, including formwork, site hoardings and other temporary site timber used for the purpose of facilitating construction, is to be procured from sustainably managed sources, independently certified by one of the top two levels as set out in the Responsible Sourcing of Materials Issues (Mat 2 and Mat 3) in the Materials section of this document. All timber used during construction must be legally sourced.
Re-used timber from off site can be counted as equivalent, but re-usable formwork complies only if it meets the above criterion.
This credit can be awarded where all the timber used is reclaimed timber.
