CDM 2007 client
For information about the duties of the client under the 2015 CDM regulations see CDM 2015 client.
The text below relates to the superseded 2007 CDM regulations and is provided as a historical reference.
The Construction (Design and Management) Regulations (CDM Regulations) are intended to ensure that health and safety issues are properly considered during a project’s development so that the risk of harm to those who have to build, use and maintain structures is reduced.
They were introduced in 1994 and came into force on 31 March 1995 following publication of European Directive 92/57/EEC on minimum safety and health standards for temporary or mobile construction sites. They were substantially revised in 2007.
The regulations impose duties on:
- The client.
- Designers.
- The CDM co-ordinator.
- The principal contractor.
- Contractors.
- Workers.
The duties of the client include:
- Taking reasonable steps to make sure arrangements for managing the project by duty holders are suitable to ensure:
- Construction work can be carried out so far as is reasonably practicable without risk to the health and safety.
- Suitable welfare facilities are provided for any person carrying out the construction work.
- Any structure designed for use as a workplace has been designed taking into account the Workplace (Health, Safety and Welfare) Regulations 1992 (the design of, and materials used in, the structure).
- Promptly providing pre-construction information to every person designing the structure and every contractor who has been or may be appointed by the client.
Where projects are notifiable under the regulations (projects which last more than 30 days or involve more than 500 person-days of construction work), the clients must also:
- Appoint a CDM co-ordinator.
- Appoint a principal contractor.
- Ensure construction work does not start unless a construction phase plan is in place.
- Ensure construction work does not start unless there are adequate welfare facilities on site.
- Provide information relating to the health and safety file to the CDM co-ordinator.
- Retain and provide access to the health and safety file.
