Existing building risk scans use BIM, surveys, photos, and point clouds to identify unknown conditions before design work commits to a direction. The goal is to find risk early, not to model everything beautifully.
Why This Matters
Renovation risk often hides above ceilings, inside shafts, below slabs, and behind outdated drawings. A targeted BIM risk scan helps design teams ask better questions before issuing proposals or design layouts.
Practical Guidance
Start With Risk Zones: Focus on plantrooms, risers, structural openings, occupied areas, hazardous materials, and congested services.
Compare Evidence: Check existing drawings against survey data, photos, scans, and site observations.
Mark Confidence: Label model areas as verified, assumed, inaccessible, or requiring investigation.
Report Decisions: Summarise what must be surveyed, opened, tested, or confirmed before design freeze.
Checklist
- Prioritise high-risk existing building zones
- Compare drawings with survey and site evidence
- Label confidence level in model areas
- List investigations required before design freeze
