International BIM teams often discover that the biggest challenge is not learning Revit. It's learning how different markets expect information to be represented, documented and reviewed.
The US, UK and Australia all use sophisticated construction documentation workflows, but project conventions, standards, units and terminology can differ.
The three markets, briefly
Imperial, code-driven
Imperial units in documentation, US-specific codes, and manufacturer-specific conventions.
Metric, ISO 19650-aligned
British Standards and ISO 19650-aligned information management workflows are common.
Metric, its own conventions
Australian Standards and drawing conventions that differ from UK practice despite shared history.
What's different about US documentation
US projects commonly use imperial units in construction documentation, although metric information may appear in engineering contexts. Teams may also encounter US-specific codes and standards, manufacturer requirements and project conventions. For MEPF BIM, the important lesson is to establish units, families, annotations, schedules and code references at project setup rather than relying on a generic template.
What's different about UK documentation
UK projects commonly use metric units and may use British Standards, project-specific requirements and ISO 19650-aligned information management workflows. Drawing conventions, terminology and documentation expectations can differ from both US and Australian projects even when the underlying engineering principle is the same.
What's different about Australian documentation
Australian projects generally use metric units and may reference Australian Standards and project-specific specifications. Drawing conventions and terminology can also differ from UK practice despite historical similarities.
A common mistake is assuming every project in a country follows one universal drawing standard — the project BEP, employer requirements, consultant standards and contractor templates can all override generic assumptions.
The list a BIM team actually has to manage
- Units and dimensioning
- Annotation and abbreviations
- Family/content standards
- Specification references
- Code and compliance references
- Drawing title blocks
- Schedules and parameter conventions
- Model exchange requirements
- Detailing expectations
- Client QA/QC procedures
Start with the project's own documents, not a country assumption
Build a project-specific BIM standard from the BEP, templates, examples, specifications and approved drawings, then test a small sample before producing the full package. For an international outsourcing team, this is more reliable than memorising national conventions — the goal isn't to "draw like an American" or "draw like an Australian," it's to deliver exactly what the project's BEP requires. It's also why our shop drawings and fabrication drawings work is set up around each client's own templates rather than a single house style.
