Design and build: outline work plan

Project plan design and build.jpg

This is an outline work plan for a private sector design and build project. For other procurement routes, including public sector projects (which may be design and build), click here.

Clicking on the stages will open a detailed schedule of the tasks necessary to complete that stage. Together these tasks represent a single, consolidated project plan from the first moment it becomes apparent a project might be required, right through to post occupancy evaluation.

Design and build

Stage 1: Business justification.

Stage 2: Feasibility studies.

Stage 3: Project brief.

Stage 4a: Concept design (design by consultant team).


Stage 4b: Concept design (design by contractor).

Stage 5a: Detailed design (design by consultant team).


Stage 5b: Detailed design (design by contractor).

Stage 6: Production information.

Stage 7: Mobilisation.

Stage 8: Construction.

Stage 9: Occupation and defects liability period.

Stage 10: Post occupancy evaluation.

Moveable stages:


  • Design and build projects involve appointing a contractor to design the development and also to construct it. The contractor might be appointed early in the project to carry out all of the design work, or later in the project to complete a design which others have begun. This means that design tasks can be attributed either to a consultant team or the contractor depending on whether the contractor has been appointed or not. As a consequence, we include two versions of the concept design stage, detailed design stage and also the process for applying for planning permission. The tender stage is moveable depending on when the contractor is appointed.
