Construction (Design and Management) Regulations

Construction (Design and Management) Regulations

28th May 2019

The Construction (Design and Management) Regulations is usually referred to in the construction industry as CDM and these rules apply to every type of construction project in the UK, including domestic construction work.  No matter how large or small the job, no matter how much time it takes, even a job that takes very little time, the CDM regulations apply.  Today we have a handy summary of the ten rules that you absolutely must comply with.

  1. CDM applies to all construction work – if you are planning construction activity, or carrying out a construction job (even a job that only takes an hour or so to complete), you must comply with CDM.
  2. Anybody tasked with working on a project must have the skills, knowledge and experience to complete the work in a competent and safe manner.  CDM regulations place a duty on everybody involved in construction work, particularly key team members, such as the client, designers and contractors, who are known as “duty holders”.
  3. Each duty holder has their own duties that they must carry out under CDM – so knowing your own duties is vital.  Duty holders are also required to co-operated, co-ordinate with and help other duty holders.  The Principal Contractor is in overall control of designers and the pre-construction stage of the project.
  4. The roles of Principal Contractor and Principal Designer must be appointed on all projects with more than one contractor. 
  5. There must only be one Principal Designer and one Principal Contractor appointed on a project at any one time. 
  6. The Health and Safety Executive (HSE) must be notified of any projects which last for more than 500 person-days (or 30 working days if more than 20 workers are employed).
  7. Pre-construction information must be provided by the client on every project.  There are CDM specific documents which may be needed at different stages of a project, including:
    1. Pre-Construction Information
    2. Construction Phase Plan
    3. Health and Safety File
  8. A construction phase plan must be created for every construction project – this is the responsibility of the Principal Contractor or Sole Contractor.  The client has a duty to make sure this plan has been created before work commences.
  9. The Principal Designer must create and develop a health and safety file which will be handed over upon completion of the project.  This is a document that is created whilst the work is being undertaken, rather than a document used to manage health and safety during the project.  It should contain all the health and safety information necessary to ensure the safety of those using, maintaining, cleaning or demolishing a building or structure after work has been finished.
  10. Contractors must be knowledgeable on the general requirements for construction sites under CDM for all activities and tasks relevant to their work.
