During a weekly BIM health review, the BIM manager compares two versions of the same architectural Revit model submitted one month apart. The newer model’s file size has doubled, synchronization time has increased by 40%, and users report sluggish performance. A model audit reveals no major geometry changes, but warnings have increased from 600 to 750, and several Civil CAD files are now imported.
What is the most likely root cause of the model performance degradation?
The BIM manager oversees both design coordination and post-handover data requirements and is asked to ensure the digital deliverables align with the owner’s long-term asset-management system.
To minimize information gaps, inconsistencies in file formats, and unclear responsibilities throughout delivery, which tool should the BIM manager rely on to define who provides what information, when, and in what format, from design through facilities handover?
Note: In the context of this exam, the term Level of Development (LOD) is used interchangeably with level of information need.
Due to unpredictable material tariffs, a campus project anticipates possibly changing its structural framing system once pricing is finalized. This could affect floor-to-floor heights across several buildings.
What method would best ensure both initial and ongoing coordination of Levels and Grids across a large multidisciplinary Revit project?
Refer to the exhibit.

A designer cannot see a 2x4 tile ceiling in the hallway area of their Reflected Ceiling Plan, but that same ceiling is visible in a 3D view. The 2x2 ceilings in the other rooms are visible in both views.
What are two possible reasons for this? (Select two.)
The BIM Execution Plan (BEP) has just been completed for a new project. To ensure all multidisciplinary team members review and understand their roles and responsibilities, what is the most effective way to distribute the BEP before the project starts and ensure it remains accessible to everyone throughout the project?
A regional user group raised awareness about a third-party add-on tool that enables a team to establish thresholds for model warnings. In addition, it automates suppressing warnings deemed negligible to a specific project.
Which two data points should a BIM manager gather to build a business case to have the tool approved for use across the firm? (Select two.)
A design team is distributing models to a construction team’s coordinator, who reports that the various models are not aligned to each other when linked into the coordination environment.
What step should the design team’s lead BIM manager take to resolve the positioning issue?
The BIM manager received a subcontractor’s 3D model containing specialty equipment to be integrated into the federated model. Upon review, they observe that:
Many elements lack consistent object styles and category assignments.
Some components are modelled with excessive detail, affecting performance.
Embedded data does not follow the project’s naming conventions outlined in the BEP.
What is the most appropriate next step when evaluating this geometry and content?
During early coordination on a hospital project, the BIM manager runs a general clash detection between all models and generates over 3,000 clash results. Many are low-priority issues, such as wall-grid overlaps and minor duct-ceiling intersections. The project’s clash matrix outlines only high-impact clashes between structural, MEP, and architecture in specific zones.
For the BIM manager, what is the most appropriate next step to align clash reporting with the project’s coordination strategy?
A museum project anticipating generative iterations is being designed by a team working across multiple time zones under a tight schedule. The client hosts weekly meetings to review various façade options, document sustainability goals, and evaluate numerous energy analyses.
What project-specific training should the design technology team provide to prepare the team for client meetings and ensure successful project execution?
