CDM Designers Duties

What is a CDM Designer?

Professional CDM 2015 Support

A Designer is defined by the Construction (Design and Management) (CDM) Regulations 2015 as “an organisation or individual whose business involves preparing or modifying designs for construction projects, or arranging for, or instructing, others to do this. Designs include drawings, design details, specifications, bills of quantity and design calculations.” HSE

Who can be a CDM Designer?

A Designer under CDM can be;

  • An architect
  • Consulting Engineer
  • Quantity Surveyors
  • Interior Designer
  • Or anyone who specifies, develops or alters designs and/or specifications as part of their work.

Principal Contractors, Contractors, Specialist Contractors, tradespeople or even commercial clients themselves can become Designers if they get actively involved in design work for a project.

Design Decisions Impact on Safety

A Designer’s decisions at any stage of the project can have an impact upon Health, Safety and Welfare of everyone involved in constructing, occupying and using, maintaining, refurbishing and eventually modifying or demolishing the building or asset. It could be said that Designers have the most influence over the Health, Safety and Welfare of a project, simply by making safety conscious decisions from the outset.

    • Communicate information related to any residual design risks to the Client, Principal Designer and/or Principal Contractor.
  • The client and principal contractor (or the contractor for single contractor projects) to help them comply with their duties, such as ensuring a construction phase plan is prepared.
    • Communicate, Cooperate and Coordinate with;
    • Any other designers (including the Principal Designer) so that all designs are compatible and ensure health and safety, both during the project and beyond.
    • All contractors (including the Principal Contractor), to take account of their knowledge and experience of building designs.

Domestic Client Duties

The duties of Designers working for a Domestic Client are the same as working for a Commercial Client. The only difference is that the Domestic Client’s CDM 2015 duties are normally taken on by the appointed Contractor (or the Principal Contractor on projects involving more than one Contractor). A Designer should consider main Contractor or Principal Contractor as the CDM Client unless the Domestic Client has formally requested the Principal Designer (where there is more than one appointed Designer) to take on and administer their duties. The Principal Designer is responsible for controlling the Pre-Construction Phase.
