What does BIM Level of Development define in PDD projects?

• A. The project budget and funding schedule.
• B. The energy performance targets for the building.
• C. The accuracy and completeness of models at each stage, guiding coordination, documentation, and collaboration expectations.
• D. The final construction permit requirements.

Answer: (C)

BIM Level of Development defines the expected reliability, content, and precision of BIM models at each project stage, which in turn sets the coordination, documentation, and collaboration requirements for the team. In PDD projects, this means specifying what information and geometry should be present at each milestone and how accurate it must be, so the team can coordinate across disciplines, perform clashes, and produce documentation that aligns with the model throughout design and construction. It ensures everyone works with a shared understanding of model quality and completeness as the project progresses.

It’s not about the project budget or funding schedule, nor about energy performance targets, nor about final construction permit requirements.
