The Survey Point represents the shared real-world or site coordinate framework. Placing or defining it consistently at the common site origin allows every building model to relate to the same survey reference for federation, site plans, civil coordination, and geographically consistent exports.

Each building should retain its own Project Base Point because this point supports the building’s local project-coordinate framework. A building may use a convenient internal datum and orientation suited to its grids, geometry, and documentation while still maintaining a transformation to the common survey system. This separation allows the buildings to remain independently manageable without losing site-wide positional accuracy.

Placing every Project Base Point at the shared site origin would eliminate the intended distinction between each building’s local coordinate basis and the common site reference. Likewise, using a single Project Base Point across all separate models is not how Revit coordinate systems operate; each model has its own internal origin, Project Base Point, and Survey Point. Option B is imprecise because the requirement is not to establish unrelated Survey Points, but to align the models to one shared site origin.

The correct arrangement is a common Survey Point reference combined with a locally appropriate Project Base Point for each building.

Reference topics: Survey Point; Project Base Point; multi-building coordination; local versus shared coordinates; site federation; building-specific origins.

A structured performance audit is the correct starting point because it evaluates the model comprehensively rather than assuming a single cause. The review should examine warning quantity and severity, file size, imported or linked CAD data, excessive views, unused content, model groups, in-place families, highly detailed components, workset configuration, and other authoring practices that can increase regeneration time and memory consumption.

In-place families are particularly relevant because numerous or geometrically complex instances can make the model difficult to maintain and may increase computational overhead. Warning trends also matter: some warnings create repeated relationship checking or indicate poor modelling practices, although warning count alone does not determine performance.

Deleting sheets or exporting only 3D views damages the project’s documentation structure and does not constitute a controlled health-improvement strategy. Clash reports evaluate multidisciplinary spatial conflicts; they do not diagnose the internal efficiency of the submitted Revit model. Loading linked files individually can be useful later when evidence specifically implicates a link, but it is too narrow as the primary health assessment.

The audit should produce documented findings, prioritized recommendations, and measurable actions that the consultant can implement without compromising required project deliverables.

The imported Civil CAD files are the strongest causal indicator. Imported CAD data becomes embedded within the Revit model rather than remaining externally referenced. Civil drawings frequently contain large coordinate extents, dense linework, hatches, proxy objects, unnecessary layers, and complex geometry. Embedding several such files can substantially increase model size, graphical processing requirements, opening time, and synchronization duration.

The audit specifically establishes that no significant native Revit geometry was added, eliminating option A as the principal explanation. Revit model backups are normally maintained externally or through version history rather than being accumulated as embedded model data in the manner suggested by option B. An increase from 600 to 750 warnings warrants review, and certain warning types can affect regeneration performance, but that increase alone is less likely to explain a doubled file size and a sudden 40% synchronization penalty.

The appropriate corrective action is to assess whether the CAD files can be linked instead of imported, clean them before use, remove unnecessary layers and objects, verify their coordinates, and purge obsolete imported definitions after removal.

The first requirement is a documented governance framework that defines how the participating firms are expected to work together. The identified failures are not limited to unauthorized access; they also include inconsistent data and breakdowns in communication. Coordination protocols must therefore establish model ownership, authorized editing responsibilities, submission requirements, quality-control gates, issue-escalation paths, communication channels, and accountability for approving changes.

Once these rules are agreed, the BIM manager can configure Common Data Environment permissions to enforce them. Implementing tighter access controls before establishing the underlying responsibilities may prevent some unauthorized edits, but it does not determine who should own each dataset, which checks must be performed, or how coordination decisions are communicated.

Option A delegates model maintenance but does not establish consistent cross-team procedures or editing rights. Option D may expose design assumptions, yet it is focused on modelling strategy and conflict identification rather than comprehensive information governance.

Effective BIM coordination depends on both procedural and technical controls. The procedural protocol comes first because it provides the basis for access configuration, quality reviews, issue workflows, model exchange, and audit requirements across the delivery team.

Reference topics: BIM coordination protocols; model ownership; editing authority; Common Data Environment governance; quality control; communication planning; risk mitigation.
