The information in these web pages will help you understand what you need to do under the Construction (Design and Management) Regulations 2015 (CDM 2015), which came into force in April 2015.
Virtually everyone involved in a construction project has legal duties under CDM 2015. These ‘dutyholders’ are defined as follows.
Client - Anyone who has construction work carried out for them. The main duty for clients is to make sure their project is suitably managed, ensuring the health and safety of all who might be affected by the work, including members of the public. CDM 2015 recognises two types of client:
Designer - An organisation or individual whose work involves preparing or modifying designs, drawings, specifications, bills of quantity or design calculations. Designers can be 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 designer 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 contractor 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 - 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. Their main duty is to plan, manage and monitor the work under their control in a way that ensures the health and safety of anyone it might affect (including members of the public). Contractors work under the control of the principal contractor on projects with more than one contractor.
Worker - An individual who actually carries out the work involved in building, altering, maintaining or demolishing buildings or structures. Workers include: plumbers, electricians, scaffolders, painters, decorators, steel erectors and labourers, as well as supervisors like foremen and chargehands. Their duties include cooperating with their employer and other dutyholders, reporting anything they see that might endanger the health and safety of themselves or others. Workers must be consulted on matters affecting their health, safety and welfare.
