The Construction (Design and Management) Regulations were introduced on the 6th April 2015 and cover management of all aspects of health, safety and welfare when relating to construction projects. These Regulations replaced the CDM 2007 Regulations.

What are these regulations for?
The CDM Regulations 2015 aim to make it easier for all individuals working in construction to improve all aspects of health and safety via the following factors:

  • Managing identified risks from start to finish
  • Using the right people for the right job
  • Cooperation and coordination of work with others
  • Being aware of risks and also how they are being managed
  • Communicating with people regarding risks, assessed factors etc

CDM Regulations 2015 Simplified
