The CDM 15 regulations places legal responsibilities on those involved in construction products giving them individual titles and roles.
Any project with more than one trade contractor requires the appointment of a Principal Designer by the Client. The Principal Designer will identify and control risks, produce a Pre-Construction Information Plan, work with the clients designers to eliminate risk in the design and ensure the appointed Principal Contractor complies with CDM 15.
