Outcome
Protect your margin
Make sure the drawings match what you're contracted to deliver.
On a design-and-construct job, the design risk sits with you. The Principal Project Requirements define what the Principal is paying for, and you're bound to deliver all of it - whether or not the consultants drew it. Where the drawings fall short of the brief, the shortfall becomes non-conforming work you rectify at your own cost; where they run ahead of it, you're building scope the contract never asked for. Both come straight off your margin.
CIM reads the Principal Project Requirements against the drawings and specifications and flags where they diverge - requirements the design hasn't picked up, and design that outruns the brief - each finding cited back to the clause and the drawing it came from.
You see the mismatches while they're still a conversation - an RFI, a variation, a design correction made while the drawing is still cheap to change. The design obligation you carry stops being a blind spot.
Before CIM
- Drawings that fall short of the brief become rework on site.
- Design that overruns the brief is scope you build for free.
- The design obligation stays a blind spot until it's built.
With CIM
- The Principal Project Requirements checked against the drawings, divergences flagged.
- Over-spec caught before it's priced or built.
- Mismatches resolved by RFI or variation before they reach site.
