The Construction (Design and Management) Regulations, also commonly referred to as the CDM Regulations, are a set of health and safety regulations that apply specifically to construction projects.
These Regulations have been revised several times so far...
The most recent version, CDM 2015, applies to all construction projects in Great Britain, and replaces the previous (2007) version of the CDM regulations.
Now we know what the CDM regulations are, what impact do they have?
Well, first of all, every construction project must comply with these regulations. CDM 2015 applies to all construction projects including domestic.
To achieve its objectives the CDM regulations place duties on virtually everyone involved in construction work, particularly on key members of the project team such as the client, designers and contractors.
The regulations specify 5 key duty holders:
Each of these duty holders have to carry out the duties given to the under CDM.
Clients must make sure that the required duty holders are appointed, that relevant information is prepared and provided to other duty holders, that welfare facilities are provided, and that the Principal Designer and Principal Contractor carry out their duties under CDM 2015.
Every designer and contractor must comply with the specific designer and contractor duties under CDM 2015. All designers must eliminate, reduce or control foreseeable risks, and all contractors must plan, manage and monitor construction work under their control so that it is carried out without risks to health and safety.
The Principal Designer has additional duties, including assisting the the Client, and putting together the Pre-Construction Information and the Health and Safety File, and takes control of the pre-construction phase and any other designers (if more than one) must share information with the Principal Designer.
The Principal Contractor has additional duties and takes control of the construction phase and all other contractors must comply with the Principal Contractors Construction Phase Plan, and any site rules and procedures.
Under CDM 2015, certain projects (usually any project lasting over 30 days with 20 workers, or involving more than 500 person days) require notification to be submitted to the HSE.
The CDM regulations also cover other health and safety requirements in addition to duty holders, including welfare requirements and general requirements for all construction sites, such as security, traffic, emergency procedures and lighting.
