Principal Designer

The Construction (Design and Management) Regulations, 2015, (CDM) aim to improve health, safety and welfare within construction, by managing the risks involved in the project from conception through to completion. The regulations created a new role of Principal Designer (PD) to manage the risks in a project in the pre-construction phase and provide relevant information to contractors.

Thomas Consulting can undertake the role of PD on any project where they are appointed as a  Designer and carry out the necessary risk assessments in order to comply with the CDM regulations.


The Regulations require that on all construction projects the client must:

  • Ensure that suitable management arrangements are in place for the project
  • Ensure that sufficient time and resources are allocated
  • Provide pre-construction information to designers and contractors
  • The Principal Designer and Principal Contractor carry out their duties
  • Welfare facilities are provided

Failure to comply with the Regulations and the duties imposed may result in heavy criminal penalties being imposed on clients.

If we….

have an idea which will save our clients time, money and risk… we communicate it


As Principal Designer, we identified that the site was in close proximity to National Grid 275kV overhead power cables which would require careful control of cranage activities to minimize the risks associated with electrocution.

A message from Thomas Consulting
Here at Thomas Consulting as other organisations during this time of uncertainty with COVID-19 we are responding to the Government recommendations to try and reduce the spread of the virus. Staff have been made aware of the steps that need to be taken if they show any signs of the infection or have been in contact with others with the symptoms and are updated with any changes daily. That said we are focused on delivering safe, reliable on-going support to both new and existing clients; having implemented measures to ensure that we are able to have staff working remotely (i.e. at home) reducing their contact both with each other and clients to keep all as safe as is possible.

Unfortunately site meetings are postponed until the current restrictions are reviewed and updated and each meeting/site visit will be assessed individually at that time. All other elements of each project will continue to be progressed where possible and each member of the team will be updating clients on their progress.

Thomas Consulting are committed to continue to review the Governments recommendations and make the necessary changes that enable our projects to be delivered on time collaboratively during this period with the minimum amount of risk.

Unfortunately this is going to be an ongoing process for the next few months with constant review; however should you need to contact any member of our team the following numbers will always be available during our normal working hours of 9am - 5pm Monday - Friday 01743 237940 (Shrewsbury), 01772 299040 (Chorley) and 01524 846022 (Lancaster).
