Principal Designer & CDM Advisor

The Principal Designer role was introduced on 6th April 2015 when the CDM Regulations were updated with the objective to simplify the process and provide improved compliance in relation to health and safety in construction projects.

Outline of the CDM requirements

CDM applies to all building and construction work including new build, demolition, refurbishment and renovation, extensions, and repairs/maintenance works.

All projects must have;

  • Workers with the right skills, knowledge, training and experience.
  • Contractors providing appropriate supervision, instruction and information
  • A written construction phase plan

Projects where there is more than one contractor involved must also;

  • Have a Principal Designer and Principal Contractor appointed in writing by the Client.
  • Provide a health and safety file, for which the Principal Designer and Principal Contractor are responsible

 How can we help?

Our extensive experience in Building Surveying, Project Management, Design and Specification provides us with a sound understanding of the design process, construction processes, and relevant legislation, all of which are essential for providing CDM advice.

We can assist with the following;

  • Identifying, obtaining and compiling the pre-construction information.
  • Ensuring that the relevant pre-construction information is provided to designers, the Principal Contractor and Contractors. Through effective communication we ensure that the right information is distributed to the right people at the right time.
  • Ensure that designers comply with their duties and co-operation with each other.
  • Liaise with the Principal Contractor throughout the duration of the appointment
  • Prepare and issue the health and safety file
