PPR vs the drawings
Check the brief against the set, clause by clause.
The Principal Project Requirements are the contract's description of the building - hundreds of clauses covering acoustics, thermal performance, services capacity, finishes, warranties and FFE. On design-and-construct you are bound to deliver every one of them, whether or not the consultants drew it. Reading all of that against a full drawing set is a job most teams do in the areas they already suspect.
CIM runs the brief as its own audit: every clause against the drawings and the specification, in both directions. Requirements the design has not picked up come back as findings, and so does design that runs past what the brief asks for. Each one cites the clause number and the sheet it was checked against.
The audit runs at tender on the pack you are pricing, and again on each design issue as the set develops. The clause that was satisfied at tender is checked again at IFC, to the same standard, so the design obligation you carry stays visible for the whole job.
Before CIM
- Hundreds of clauses checked wherever someone had the brief open.
- A requirement the drawings missed turns into rework at your cost.
- Design that runs past the brief gets built and nobody priced it.
With CIM
- Every clause run against the drawings and the spec, in both directions.
- Each finding cited to the clause number and the sheet.
- The audit re-runs on every design issue, to the same standard.
