Principal Designer Service

Each project is unique! An individual project will be ‘shaped’ by the Project Brief, the Client circumstances and arrangements, the existing site circumstances, plus the numerous project stakeholder requirements, interests and expectations. A construction project will also require a proactive, diligent and coordinated approach, involving professional inputs required from a wide and diverse assembly of people and organizations.

Each construction project is delivered within a bespoke context. . It is essential that each project is also delivered with due consideration for safety – for all persons affected by a building’s design, construction, use, maintenance and eventual disposal. The Construction (Design and Management) Regulations 2015 gives reference to three legally-accountable parties: The Client, the Principal Designer and the Principal Contractor. All duties are clearly listed within the CDM Regulations.

For clarity, the Principal Designer duties are also summarised below.


  • Plan, manage, monitor and coordinate health and safety matters to ensure that, so far as is reasonably practicable, the project is carried out without risks to health and safety
