NEC have published a new secondary option X29 based around climate change. It is quite a detailed option and also comes with guidance notes to be considered when putting X29 together initially and then managing it on a live project. There is a different version of X29 for each of the contracts within the NEC family.
Here you can download a copy of the NEC4 ECC X29 clauses for your information.
If you wish any other versions of X29 for other contracts just drop us a message on our contact page and we will be happy to provide it.
