CDM Regulation Changes and the Principal Designer Role
The CDM regulations changed on 6th April 2015 with an objective to simplify the process to provide improved compliance and health and safety outcomes. Part of this change was the introduction of the Principal Designer role.
Outline of the CDM requirements
All Projects must have:
- workers with the right skills, knowledge, training and experience (this is known as the competency criteria)
- contractors providing appropriate supervision, instruction and information
- a written construction phase plan
Projects where more than one contractor is involved must also:
- appoint, in writing by the client, a Principal Designer and Principal Contractor
- provide a health and safety ﬁle, for which the Principal Designer and Principal Contractor are responsible
Additionally all projects must be notified to the Health and Safety Executive if work is scheduled to:
- last longer than 30 working days AND have more than 20 workers working simultaneously at any point in the project
- OR exceeds 500 person days
Key changes to the CDM regulations
The Principal Designer will be the individual or organisation responsible for the pre-construction phase. The Principal Designer and the Client share the duties previously undertaken by the now redundant role of the CDM co-ordinator. The Health and Safety Executive state that the Principal Designer must ‘be a designer’, however they define a designer as an individual who is competent to either carry out or instruct others to perform the necessary design work.
This role is focused on the pre-construction phase but continues into construction phase where design work is modified, new design work is carried out and works are undertaken during the DLP. The Principal Designer also retains responsibility to ensure that other duty holders carry out their obligations throughout the contract, such as the provision of the health and safety file.
Although in practice the Client may delegate most functions, the responsibility to ensure they are implemented cannot be delegated. The client must satisfy themselves that the appointed designers and contractors have adequate levels of skill and experience, however there is no longer an explicit duty to check competence. The client retains full legal responsibility for the duties of the Principal Designer and Contractor if formal appointments are not made when required.
The Principal Designer role should not be confused with the role of an architect. The Principal Designer may not be directly responsible for the production of the physical design material and their role cannot be novated from the client to the Principal Contractor. The Principal Designer role always remains a direct appointment of the client.
