In this article, Mike Webster provides a summary of published discussions on key issues relating to the CDM 2015 Principal Designer duties. It will provide insight into and training on this new role introduced in the CDM 2015 Regulations.
The Construction (Design and Management) Regulations (CDM) are the primary regulations for managing the health, safety and welfare of all construction projects in Great Britain. CDM 2007 has been replaced, and CDM 2015 came into force on 6 April 2015.

A range of organisations has published discussions on key issues relating to the Principal Designer duties. For ease of reference, we have collated these sources and provided links to them in this post.
