Model coordination & clash detection — ABNT NBR ISO 19650 & Decreto 10.306 (Brazil)
A BIM Coordinator runs the model-coordination cycle on a Brazilian delivery-phase project: confirming the BIM BR mandate context (Decreto 10.306/2020), aligning the BIM Execution Plan with ABNT NBR ISO 19650-2, federating discipline models with NBR 15965 classification, and driving clash-detection cycles through to accepted information deliverables.·Linked profile: BIM Fundamentals Profile·Journey for BIM Coordinator

🇧🇷BRA
Six-stage navigational layer linking the coordinator to the ABNT NBR ISO 19650-1/2 clauses, the Decreto 10.306 mandate, BIM-BR programme guidance, and BIM Forum Brasil competency references that govern each stage of the coordination journey.
Project context: Anchored to the canonical Clash Detection AFD (AFD.4040.V0.1); calibrated for public-sector projects in scope of the BIM BR strategy.

Mandate context & appointment
●IM responsibility · Lead Appointed Party — BIM coordination function
Confirm the project's position under the BIM BR mandate and the coordinator's appointment within the delivery team.
Embedded guidance
Decreto 10.306/2020 phases BIM into federal works: design uses from 2021, construction from 2024, and full lifecycle from 2028. Confirm which phase applies and record it in the appointment.
Verify whether the contracting body mandates BIM under the Decreto or by tender condition
Confirm the coordination role and authority in the appointment documents (ABNT NBR ISO 19650-2 §5.1)
Register the appointing party's exchange information requirements as the coordination baseline
●IM responsibility · Lead Appointed Party — BIM Coordinator with task-team leads
Align the BIM Execution Plan with ABNT NBR ISO 19650-2 and mobilise the task teams it commits.
Embedded guidance
The BIM Execution Plan is the coordination contract. Map each task team's deliverables to the master information delivery plan before models start arriving.
Consolidate task-team capability and capacity assessments (§5.3.2)
Fix the federation strategy and model breakdown in the BEP
Agree naming, origin, units and classification conventions up front
