Model Health Review
Review model conditions that may affect stability, usability or downstream delivery.
BIM AUDIT • QA/QC • MODEL HEALTH • DELIVERY READINESS
BIM Model Audit & QA/QC Services
Review BIM models against defined project standards, information requirements and delivery expectations — identifying model-health issues, naming inconsistencies, coordinate problems, information gaps, coordination risks and deliverable-readiness concerns.

Model Quality Review
A Model Can Look Complete and Still Contain Delivery Risks
A BIM model may appear visually complete while containing inconsistent naming, model-health issues, incorrect links, coordinate problems, missing information or unresolved project conditions.
BIM auditing provides a structured review against agreed project requirements and delivery criteria.
The purpose is not simply to find errors, but to make model readiness and open issues more visible before delivery.

Model Quality Control
“Model Opens” Does Not Automatically Mean “Model Is Ready”
A model can open, display correctly and still contain information or coordination issues that affect downstream use.
Model readiness should be judged against its intended purpose, project requirements and delivery stage.
Healthy ≠ Compliant
A technically stable model
may still fail
project standards.
Complete ≠ Coordinated
Model content may be present
while discipline interfaces
remain unresolved.
Detailed ≠ Correct for Stage
More geometry
does not automatically
mean the model matches
required LOD or LOI.
Delivered ≠ Accepted
Project deliverables
may still require
formal review
and approval.

Audit Control
QA Works Best When the Review Criteria Are Defined Before Delivery
An audit should not depend on personal preference or inconsistent review methods.
Project-specific criteria create a clearer basis for identifying, classifying and closing model-quality findings.
Defined Criteria
Review against
agreed project
requirements.
Finding Classification
Group observations
by relevant
issue type.
Revision Traceability
Keep findings
connected to
the audited
model revision.
Action Ownership
Route corrective
actions to
responsible teams.
Recheck Status
Verify selected
corrections before
audit closure.
Delivery Status
Keep readiness
separate from
formal project acceptance.

Audit Scope Clarity
BIM QA/QC Reviews Model Quality — Not Every Project Responsibility
A BIM audit can review model and information quality against agreed project criteria.
It does not independently certify structural adequacy, MEP engineering calculations, code compliance, constructability, professional design responsibility or contractual acceptance unless those services are separately defined within the appropriate scope.
BIM Quality
Review model
and information
requirements.
Engineering Quality
Technical design responsibility
remains with
the appropriate
project professionals.
Constructability
Requires broader
project-specific review
beyond model-health auditing.
Formal Acceptance
Remains subject
to the project's
defined approval
and contractual process.

Frequently Asked Questions
BIM Model Audit FAQs
What does a BIM model audit review?
Depending on scope, an audit can review model health, naming, coordinates, linked content, required parameters, LOD / LOI, project standards and delivery readiness.
Can models be audited against a BIM Execution Plan?
Yes. Where a BEP defines measurable BIM requirements, model information can be reviewed against those criteria within the agreed scope.
Can a BIM audit identify naming and coordinate problems?
Yes. Naming conventions, project coordinates and selected model-structure requirements can form part of the audit.
Can LOD and LOI be reviewed?
Yes, where project-specific LOD and LOI requirements are available. The review should be aligned with the intended project stage and BIM use.
Can a model be re-audited after corrections?
Yes. Selected findings can be reviewed again after responsible teams have updated the model information.
Does passing a BIM audit mean the model is fully constructible?
No. BIM audit compliance relates to the defined model-quality and information criteria. Constructability, engineering, code compliance and project approval require their own appropriate review processes.
