The process is numbered because the sequence is functional.
Each stage closes a real project decision before the next one begins.
1
Define the project
Site review, brief, constraints, budget context and project priorities.
2
Develop the design
Concept development, spatial testing, materials and coordinated documentation.
3
Prepare the build
Procurement, sequencing, scope coordination and site planning.
4
Deliver and close
Construction review, completion checks, handover and final project closeout.
