Commissioning rule-based model checking without agreeing rule scope and responsibility assignments
Mott MacDonald and Ramboll both rely on agreed rules and delivery workflow mapping, so rule governance must be defined with the project BIM execution plan decision owners.
Running coordination reviews without a BIM execution plan cadence that supports iteration speed
Arup warns that slow iteration happens when the BIM execution plan is not tightly defined, so review cycles need a defined cadence that matches design decision checkpoints.
Expecting federated model handover packaging to work without active client participation
HOK notes that governance requires active client participation in BIM execution plan decisions, so a client must stay involved in responsibility and delivery packaging decisions.
Underestimating the dependency on client CDE readiness for deeper automation
Mott MacDonald signals that deeper API automation depends on client CDE maturity, so the Common Data Environment operating model must be aligned before automation-heavy workflows are expected.
