Building Information Modelling (BIM) enables project teams to develop and manage digital representations of buildings and their associated information. Before models and model-derived documents are issued for their intended use, project teams may carry out a structured review to establish whether the information meets agreed requirements.

A BIM model review examines the quality, consistency and suitability of model information. Depending on the project, this may involve architectural, structural and mechanical, electrical and plumbing (MEP) models.

The review process helps identify incomplete information, coordination conflicts, incorrect references and unresolved issues before the next project stage.

== Purpose of BIM Model Review ==

A model may contain detailed three-dimensional geometry without necessarily meeting all the requirements for its intended use.

For example, a model may show the positions of ducts, pipes and structural members but omit installation clearances, equipment access requirements or information required for construction documentation.

A structured review therefore considers both geometric accuracy and the information associated with model elements.

== Common BIM Model Review Stages ==

A model review process can include the following activities:

# Model standards verification: Check file naming, model structure, project coordinates, levels, grids and other requirements defined in the BIM Execution Plan.
# Level of Development review: Examine whether model elements contain the agreed geometry and information for their intended purpose. Different elements may require different development levels.
# Multidisciplinary coordination: Review architectural, structural and MEP models together to identify relevant spatial conflicts and interfaces.
# Issue tracking: Record significant issues, assign responsible parties, document decisions and track agreed corrections.
# Revision verification: Confirm that approved changes appear in the correct model versions and associated documentation.
# Information release review: Check that the required deliverables, approvals and outstanding issue records are available before issuing information.

The sequence and extent of these activities depend on the project's contractual arrangements, information requirements and delivery procedures.

== Model Coordination and Clash Detection ==

Clash detection is one component of BIM model review. It identifies potential geometric conflicts between model elements or disciplines.

Not every detected clash represents a construction problem. Some may result from modeling conventions, acceptable overlaps or temporary design conditions.

Reviewers should assess findings against the project's design intent, construction requirements and agreed tolerances before assigning corrective actions.

Clash detection alone does not establish whether a model is suitable for release.

== Information Requirements and Model Quality ==

Model quality depends partly on how clearly project information requirements are defined.

These requirements may address element properties, classification, model geometry, naming conventions, coordinate systems, exchange formats and the intended use of deliverables.

Project teams may use automated model-checking software alongside manual technical reviews. Automated checks can identify certain inconsistencies, but they cannot independently resolve all design decisions or contractual responsibilities.

== Responsibilities and Approval ==

Responsibility for preparing, reviewing and authorising project information should follow the relevant appointments, information-management arrangements and project procedures.

BIM coordinators may organise technical reviews and issue registers, while discipline teams address information associated with their work.

Model review should not be confused with engineering design approval. The existence of a completed coordination checklist does not, by itself, establish contractual acceptance or authorisation for construction.

== Record Keeping and Information Release ==

A documented release procedure may record the model revision, review date, responsible parties, outstanding issues and applicable approval status.

Where issues remain unresolved, the project team should determine whether the information may be issued with documented limitations or must be withheld pending further action.

Maintaining these records helps distinguish information prepared for review, coordination or construction use and supports traceability when subsequent revisions occur.

== Limitations ==

BIM model review can improve information consistency and provide greater visibility of coordination issues. However, it does not eliminate design errors, unexpected site conditions or the need for professional judgement.

Its effectiveness depends on the quality of source information, the completeness of model requirements, the competence of reviewers and the timely resolution of identified issues.
