Legal requirements: A summary

Construction (Design and Management) Regulations 2015 (CDM 2015)

The Construction (Design and Management) Regulations 2015 came into force in Great Britain on 6 April 2015.

CDM 2015 is divided into five parts:

  • Part 1 deals with the application of CDM 2015 and definitions
  • Part 2 covers the duties of clients for all construction projects. These duties apply in full for commercial clients. However, the duties for domestic clients normally pass to other dutyholders
  • Part 3 covers the health and safety duties and roles of other dutyholders, including:
  • Part 4 contains general requirements for all construction sites
  • Part 5 contains transitional arrangements and revocations

HSE has published Legal Series guidance that supports CDM 2015 and explains it in more detail.
