Short answer: outsourcing BIM works best when the package, inputs, standards, level of development, review points and file formats are agreed in writing before modeling starts. The checklist below covers what US and European firms usually need to settle.
1. Define the package
- Which building, levels or zones are included, and which are not.
- Which disciplines: architecture, structure, MEP, landscape.
- What the outputs are used for: coordination, permit set, construction documents, renovation design, handover.
2. Share the right inputs
- Drawings, models or point clouds, with dates and revision status.
- Your Revit template, title blocks, families and naming conventions.
- Known gaps or open design decisions.
3. Agree standards and detail
- US: units (imperial or metric), sheet sizes, LOD requirements as defined in your contract or BIM requirements.
- UK and Europe: information requirements, BEP, naming and status codes, and classification where your project references the ISO 19650 series or the UK BIM Framework.
4. Plan reviews and communication
- Milestones and review points, and who signs off each one.
- A regular update or call time that suits both time zones.
- How questions are logged and answered.
5. Settle files, security and responsibilities
- Native and exchange formats, software versions and folder structure for handover.
- Transfer method, NDA and confidentiality terms before files are shared.
- Design responsibility, code compliance and sealing stay with the professionals of record.
TipStart with a small, well-defined pilot package. It tests standards, communication and review loops before larger work.
