Health & Safety (CDM)

The history of CDM
The Construction (Design and Management) Regulations 1994 came into force in March 1995.
Their purpose was to improve the management of health & safety throughout the construction phase of all non-domestic projects lasting long enough for the regulations to apply.
On 6 April 2007, the regulations were updated and came into force as the Construction (Design & Management) Regulations 2007.
Under these regulations, the Client had to appoint a CDM Co-ordinator (formerly Planning Supervisor) who would be his/her key health and safety advisor during the project.
On 6 April 2015, the CDM regulations were revised again.
These new CDM2015 regulations apply to all projects, including domestic ones, and the Client must appoint a CDM Principal Designer* who has the 'skills, knowledge and experience' of both design and health & safety to plan, manage an monitor health & safety during the design phase of any project.

* Under certain circumstances, the client can pass his/her duties to a Principal Designer or the Principal Contractor
