Stage 3 | DETAILED DESIGN AND BUILING REGULATIONS
This stage is to develop the technical information of how the project will be built and is usually undertaken after planning permission is granted.
Stages 3 and 4 tend to run concurrently for the sake of efficiency and in speeding up the process but can be separated depending on the service to be provided.
During this stage other consultants such as structural engineers become more involved and the building fabric and performance are developed and finalised. Other consultants may be for the preparation of SAP calculations which may be asked for in approving the thermal performance of the building.
Target stage 3 : is a submission for Building Regulations approval.
