"Carl Fox of Fox Associates, was our project manager for the external renovation, including re-roofing of our challenging old house. He managed the selection of the main contractors and throughout supervised the complicated work with scrupulous attention to detail and watchfulness. A good working relationship with contractors and clients was maintained with tact and humour. We were constantly thankful to be under his calm and considerate stewardship."

“Carl’s strength was his ability to manage a complex team of specialist contractors in order to bring the project in on time and to budget without compromising the client’s exacting brief. His dedication and commitment to achieving a successful project outcome was impressive. His ability to communicate at all levels and ensure a thorough understanding of the complex issues was equally impressive as was his professionalism.”

The Principal Designer

A Principal designer is a designer (from an organisation or an individual) who is appointed by the Client to take control of the pre-construction phase of any project involving more than one contractor.

Principal Designers have an important role in influencing how the risks to health and safety are managed throughout a project.

Design decisions made during the pre-construction phase have a significant influence in ensuring the project is delivered in a way that secures the health and safety of everyone affected by the work.

Client confidence

Our clients, whether a large corporation or an individual property owner, can have complete confidence that we provide expert, impartial advice at every stage of the appointment.

Acting as Principal Designers Fox Associates complete the following tasks:


Plan, manage, monitor and coordinate health and safety in the pre-construction phase. In doing so they must take account of relevant information (such as an existing health and safety file) that might affect design work carried out both before and after the construction phase has started.

Advising the Client

Help and advise the client in bringing together pre-construction information, and provide the information designers and contractors to carry out their duties.

Working with designers

Work with any other designers on the project to eliminate foreseeable health and safety risks to anyone affected by the work and, where that is not possible, take steps to reduce or control those risks

Communication & cooperation

Ensure that everyone involved in the pre-construction phase communicates and cooperates, coordinating their work wherever required.

Liaison with the contractor

Liaise with the principal contractor, keeping them informed of any risks that need to be controlled during the construction phase.

Domestic Clients

On a domestic client project where the domestic client does not appoint a principal designer, the role of the principal designer must be carried out by the designer in control of the pre-construction phase.

When working for a domestic client, the client duties will normally be taken on by another duty holder (often the principal contractor on projects involving more than one contractor). However, the principal designer can enter into a written agreement with the domestic client to take on the client duties in addition to their own.
