A multidisciplinary healthcare project has multiple firms contributing to a federated model. Early coordination reviews reveal data inconsistencies…

In complex multidisciplinary BIM projects, data inconsistencies, unauthorized model modifications, and communication failures stem from a lack of formal information governance. According to ISO 19650 standards and BIM management principles, the most critical initial step is establishing clear management protocols via a BIM Execution Plan (BEP) and information exchange standards. These protocols define clear model authoring boundaries, element ownership, permission structures, quality control procedures, and official communication channels. Establishing governed rules upfront provides the foundational framework needed to align multidisciplinary project teams, enforce editing compliance, streamline coordination, and mitigate project delivery risks. Technical controls or individual firm strategies cannot succeed without overarching, mutually agreed-upon project governance protocols.

Option A: Leaving each firm to independently review models without centralized governance leads to siloed workflows, inconsistent quality checks, and uncoordinated resolutions.

Option B: Restricting access in the CDE is a technical enforcement measure, but technical restrictions without agreed governance protocols fail to clarify ownership and communication.

Option D: Requesting isolated modeling strategies from individual firms focuses on internal firm practices rather than defining unified project-wide communication, ownership, and coordination protocols.
