The Project Supervisor Design Process shall “organise cooperation between Designers on the same project and, so far as is reasonably practicable, ensure coordination of their activities in relation to the design of the project with a view to protecting the safety, health & welfare of persons involved in construction work”. [Regulation 11.1(c)] This includes organising cooperation and ensuring, so far as is reasonably practicable, the coordination of the activities of all temporary works Designers.

The Guidelines state “The PSDP should pay particular attention to potentially catastrophic issues such as overall instability of the structure during the various stages of construction." In coordinating the activities of the various Designers where the integrity of a structure during construction is an important safety issue, the PSDP should insist ( and be in a position to insist ) that one designer takes overall design responsibility for the stability of a structure during the envisaged construction process and that a suitably qualified engineer be employed to liase with the Design team

The guidelines state “The requirement of the Construction Regulations for the PSDP to co-ordinate the design of works, including the design of temporary works, does not eliminate the need for the appointment (generally by contractors) of competent temporary works engineers who understand the complexity of the forces involved in temporary works-permanent works interaction and who can design the temporary works to take account of these forces”

The PSDP, in preparing the Safety and Health Plan on a preliminary basis, is required to include further information, such as the conclusions reached by designers and the project supervisor as regards the taking account of the general principals of prevention and any relevant safety and health plan or safety file [Regulation 12(1)(v)].

The Project Supervisor Design Process (PSDP) is responsible for the preparation of the Safety File appropriate to the characteristics of the project, containing relevant safety and health information, and delivering it to the Client on completion of the project. [Regulation 13] The project supervisor for the construction stage PSCS) must “coordinate arrangements among contractors to ensure the provision of the relevant information, in writing, necessary for the project supervisor for the design process to complete the safety file”. They PSCS must also provide in writing to the PSDP all relevant information necessary to complete the Safety File. [Regulation 21]
