A complete absence of clashes on a large multidisciplinary retail project is more likely to indicate an input or positioning problem than perfect coordination. The BIM manager should first confirm that every published model uses the approved shared-coordinate system and appears in the correct horizontal position, elevation, and orientation. Models exported using unrelated internal or project coordinates may be separated by a substantial distance in the coordination space, preventing the clash engine from detecting intersections.
After correcting the source models, the teams should republish the designated coordination views and verify visually that the architectural, structural, and building-services models overlay correctly before rerunning clash detection. Publication status, model versions, included geometry, and coordination-space assignments should also be checked.
Adding sheets does not affect three-dimensional clash detection because sheets are documentation containers rather than coordinated model geometry. Proceeding on the assumption that zero results means zero issues would bypass essential input validation. A case study would be inappropriate until the unexpected result has been investigated and confirmed.
The governing principle is that clash results are only reliable when the model inputs, coordinate systems, publication settings, and federation are validated first.

A BIM Execution Plan establishes the operational framework by which BIM will be implemented on a project. Two core components are the modeling standards that govern how information is authored and the technology ecosystem that enables production, exchange, review, coordination, and delivery. Modeling standards typically address file structure, naming conventions, model segmentation, coordinates, units, worksharing, content requirements, quality-control procedures, and information expectations. The technology ecosystem identifies approved authoring applications, software versions, cloud platforms, coordination tools, interoperability formats, add-ins, and supporting hardware or infrastructure.
An LOD or level-of-information matrix may be attached to or referenced by the BIM Execution Plan, but general project specifications are contract or technical-design documents rather than defining components of the BEP itself. Likewise, collaboration protocols are normally covered by a BEP, but "project playbook" is not the precise paired component represented by the Autodesk curriculum. A conventional project schedule may influence BIM deliverables, yet it is not equivalent to the BIM production and information-delivery plan.
Therefore, option B contains two elements that directly belong to BIM implementation planning and govern consistent execution across disciplines. These provisions prevent incompatible software, inconsistent modeling practices, and uncontrolled information exchanges.

Scheduled, filtered reports provide the most efficient and controlled method of communicating coordination status to a project manager who does not routinely operate the coordination platform. The BIM manager can configure the report to include relevant issue attributes such as discipline, status, assignee, due date, location, priority, and creation date. A weekly schedule then delivers a consistent snapshot without requiring repetitive manual extraction.
Saving the reports within the project environment also maintains a traceable project record. The project manager can compare reporting periods, identify overdue items, review issue closure rates, and escalate unresolved coordination risks without maintaining a separate unofficial dataset.
Manual Excel exports introduce unnecessary administrative effort and create a risk that the spreadsheet becomes outdated immediately after issue statuses change. Using Excel as the principal tracker would fragment the project's source of truth and could result in conflicting issue records. AutoCAD's interference functions are not the appropriate mechanism for managing multidisciplinary Revit coordination issues and would not preserve the associated cloud-based issue workflow, assignments, comments, and status history.
The correct strategy is to retain issue management in the approved coordination platform while tailoring automated reporting to the stakeholder's information needs.

A mandatory multidisciplinary review session is the strongest method for ensuring that contributors understand the BEP rather than merely receive it. The session allows the BIM manager to explain model ownership, coordination procedures, file structures, software requirements, information exchanges, quality-control responsibilities, naming conventions, issue workflows, and escalation processes. It also enables each discipline to identify ambiguities and confirm acceptance before implementation begins.
Following review and approval, the BEP should be retained as the official controlled project document in the Common Data Environment. This provides an accessible reference and establishes the approved baseline against which later revisions can be tracked.
Uploading a live copy to a shared folder is necessary for accessibility, but distribution alone does not demonstrate that participants understand their obligations. Including the BEP in the contract provides formal status but does not replace operational onboarding. Email signatures confirm receipt or acknowledgment, not comprehension, and can lead to disconnected copies outside the controlled document environment.
The best process combines formal review, multidisciplinary approval, controlled publication, and ongoing accessibility. Among the available choices, option B most completely addresses understanding, agreement, and official document control.

The BIM manager should restore the linked instance to its previously defined shared-site position. Selecting the appropriate Shared Site and choosing to move the instance to that defined site reapplies the established coordinate transformation, including the intended horizontal position, elevation, and orientation. This is substantially more reliable than attempting to reconstruct the placement manually.
Using the Move command would rely on visual alignment or manually entered offsets and might not reproduce the original coordinate relationship precisely. Even a small positional or rotational error could affect consultant overlays, federated coordination, survey references, and downstream exports.
Publishing coordinates is not the appropriate recovery action after the link instance has been accidentally dragged. Publishing from the incorrectly positioned instance could redefine or overwrite the coordinate relationship based on the displaced location rather than restore the approved position. The source CAD file itself has not changed, so requesting that the consultant revise and resubmit it would not address the actual cause.
After restoring the defined site position, the BIM manager should verify the alignment against known control points and repin the link to prevent further unintended movement.
