CDM 2015 – A practice wide approach Share this article

The 6th of April 2015 saw the implementation of the updated Construction (Design and Management) Regulations 2015, and replace the 2007 regulations. They apply to all construction projects in Great Britain.

 The objective of the changes from CDM 2007 were to:

  • Maintain or improve worker protection
  • Simplify the regulatory package
  • Improve health and safety standards on small construction sites
  • Implement the Temporary or Mobile Construction Sites Directive (TMCSD) in a proportionate way
  • Discourage bureaucracy
  • Meet better regulation principles


Highlighting the changes

The regulations impact all those involved in construction, and define duties for the client, principal designer, designers, principal contractor, contractors and workers. Below is a summary of the changes and the implications:

  • The CDM coordinator role is replaced by the Principal Designer role.
  • Domestic clients are now no longer exempt, however their duties are transferred to the designer or contractor.
  • Designers are required to have the skills, knowledge and experience to undertake the work.
  • The Approved Code of Practice has been withdrawn, and replaced with L series guidance and industry guidance.


Projects started before the 6th of April 2015 where a CDM coordinator has not yet been appointed, will require the client to appoint a Principal Designer. If a CDM coordinator has been appointed, then a Principal Designer will need to be appointed to replace the CDM coordinator by the 6th of October 2015.

Cundall acting as designers

Cundall acting as designers, has always offered total solutions that saves our clients time, money and effort whilst delivering award winning projects with health and safety underpinning the design. This will continue with CDM 2015, where we are required to:

  • Have the skills, knowledge and experience necessary to fulfil the role that we are appointed to undertake
  • Assist the client with his duties
  • Design to take into account the general principles of prevention and any pre-construction information


Cundall acting as principal designer

The new role of Principal Designer must be undertaken by a designer who has the technical knowledge of the construction industry relevant to the project, and the skills, knowledge and experience to understand, manage and coordinate the health and safety of the pre-construction phase, including any design work carried out after construction begins. Where the Principal Designer is an organisation, it must have the organisational capability to carry out the role. Cundall as a multi-disciplinary engineering practice is pleased to confirm that we shall offer the service of a principal designer, with the duties laid out below;

  • Ensure the client is aware of his duties
  • Plan, manage and monitor the pre-construction phase and coordinate matters relating to health and safety during the pre-construction phase to ensure that, so far as is reasonably practicable, the project is carried out without risks to health or safety
  • Take into account the general principles of prevention and, where relevant, the content of any construction phase plan and health and safety file
  • Identify and eliminate or control, so far as is reasonably practicable, foreseeable risks to the health or safety of any person constructing, maintaining, cleaning or using the works
  • Ensure all designers comply with their duties
  • Ensure that all persons working in relation to the pre-construction phase cooperate with the client, the principal designer and each other
  • Assist the client in the provision of the pre-construction information and so far as it is within the principal designer’s control, provide pre-construction information, promptly and in a convenient form, to every designer and contractor appointed, or being considered for appointment, to the project
  • Liaise with the principal contractor for the duration of the principal designer’s appointment and share with the principal contractor information relevant to the planning, management and monitoring of the construction phase and the coordination of health and safety matters during the construction phase
  • Assist in the preparation of the health and safety file
