How to Select an Architectural BIM Company
When comparing BIM firms, architecture and construction companies should check:
- LOD capability – Does the company support the LOD required for your project?
- Revit expertise – Ask whether the team has experience with your Revit version, templates and families.
- BIM standards – Check experience with your BEP, ISO 19650 requirements and project standards.
- Coordination – Confirm whether architectural, structural and MEP models can be coordinated.
- Project experience – Request examples from a similar building type.
- Turnaround time – Establish milestone dates before starting.
- QA/QC process – Ask how model checking, clash detection and drawing validation are handled.
- Data security – Establish file-transfer, access-control and IP requirements.
- Communication – Confirm project managers, working hours and review procedures.
- Sample model – A small test/sample is useful for checking modeling standards before a large outsourcing engagement.
