What capability does BIM enable to reduce rework and improve coordination?

• A. Clash detection to reduce rework.
• B. Eliminating the need for on-site supervision.
• C. Removing the design phase entirely.
• D. Automatically generating final construction drawings without review.

Answer: (A)

BIM’s key capability here is clash detection, the automatic checking of the integrated digital model for interferences between different trades and systems. By bringing all components—structural, architectural, MEP, etc.—into one federated model, it’s possible to run interference checks that reveal where a pipe might collide with a duct, or where a beam blocks a conduit, long before anything is built. Detecting these clashes early lets the design team resolve conflicts in the model, update drawings and schedules, and share a clear set of issues with the whole project team. That reduces on-site rework, speeds up decision-making, and improves coordination across disciplines because everyone is working from the same accurate, up-to-date information.

Other options don’t fit because BIM doesn’t eliminate the need for on-site supervision or remove the design phase; nor does it automatically produce final construction drawings without review. BIM enhances coordination and planning, but human oversight and iterative design remain essential.
