Under the Construction Design and Management Regulations (CDM Regs) 2015, the main duty holders on a construction project are:
Client
Commercial
Commercial clients have construction work carried out as part of their business. This could be an individual, partnership or company and includes property developers and companies managing domestic properties.
Domestic
Domestic clients have construction work carried out for them but not in connection with any business – usually work done on their own home or the home of a family member. CDM 2015 does not require domestic clients to carry out client duties as these normally pass to other duty holders.
Designer
A designer is an organisation or individual whose work involves preparing or modifying designs, drawings, specifications, bills of quantity or design calculations. Designers can be landscape architects, architects, consulting engineers and quantity surveyors, or anyone who specifies and alters designs as part of their work. They can also include tradespeople if they carry out design work.
The designer’s main duty is to eliminate, reduce or control foreseeable risks that may arise during construction work, or in the use and maintenance of the building once built. Designers work under the control of a principal designer on projects with more than one contractor.
Principal Designer
A Principal Designer (PD) is appointed by the client to control the pre-construction phase on projects with more than one contractor. The Principal Designer’s main duty is to plan, manage, monitor and coordinate health and safety during this phase, when most design work is carried out.
Principal Contractor
A Principal Contractor (PC) appointed by the client to manage the construction phase on projects with more than one contractor. The Principal Contractor’s main duty is to plan, manage, monitor and coordinate health and safety during this phase, when all construction work takes place.
Contractor
A Contractor is an individual or business in charge of carrying out construction work (eg building, altering, maintaining or demolishing). Anyone who manages this work or directly employs or engages construction workers is a contractor.

Contractors work under the control of the principal contractor on projects with more than one contractor.

Workers include: plumbers, electricians, scaffolders, painters, decorators, steel erectors and labourers, as well as supervisors like foremen and chargehands.
