CDM Services – Principal Contractor

What is CDM 2015 ?

The Construction Design and Management Regulations 2015 (CDM) are intended to ensure that all health and safety issues are properly considered during all projects development so any risk of harm to those who construct, use and maintain is eliminated or reduced.

One of the key changes introduced with CDM 2015 is the replacement of the CDM Coordinator (CDMC) with a Principle Designer (PD). The PD has the responsibility for the coordination of health and safety during the pre construction phase. Reason for the change in the CDM Regulations was to ensure that during the design phase responsibility is given to an individual who has the ability to influence the design.

Domestic Clients can choose to have a written agreement with the Principle Designer to transfer their duties to the Principle Designer. The Principle Designer SHOULD be appointed as early as possible in the design process and at least before the start of the Construction Phase, so they have sufficient time to carry out their duties and manage the pre construction and construction phases. If a Client fails to appoint a Principle Designer the Client MUST carry out those duties.

If Domestic Clients on projects involving more than one contractor fail to appoint a Principle Designer and Principle Contractor those duties will fall to the designer and contractor in control of the pre construction and construction phases.

The HSE must be notified of the site and the works being carried out if the construction work is expected to either

  1. project to be notified if the works exceed 30 Construction Days with 20 or more workers
  2. projects exceed 500 person days of construction work

Notification of the project to the HSE is via the HSE Website and by the completion and submission of the electronic notification form.
