CDM Services

These days, health and safety on site is an important and high profile issue nationwide, and The Construction (Design and Management) Regulations 2015 place responsibilities on the client including domestic clients for the first time under the regulations to ensure that this legislation is complied with.

Domestic clients may discharge their duties onto the contractor or agreeing with the designer that they coordinate and manage the project through the construction phase rather than the role automatically passing to the contractor.

The Regulations set out statutory duties for those involved in both planning and managing construction work and apply to ALL construction work.


Extract from CDM 2015 as follows:
