How a Legacy Building Was Digitised Without CAD or BIM
A brownfield facility was converted into a smart asset using 3D scans and IoT, proving that even older buildings can go digital with the right approach.
Sector/Industry
Commercial
Platform
Nhance Digital Twin
Solution
Photogrammetry + Asset & Document Mapping
PROBLEM
Bringing Visibility to a Brownfield Site
This brownfield site had no BIM, no CAD, and minimal documentation. Any digitisation effort seemed impossible due to age and lack of as-built data. Yet, the facility teams needed visibility, better scheduling, and asset control.
SOLUTION
Creating a Digital Twin Using Just Scans and Sensors
Nhance performed high-precision photometric scans, converting point clouds into a live model. Assets and zones were tagged, and IoT sensors were overlaid for maintenance and analytics.
- Full digital twin created from 3D scans
- No CAD or BIM required
- Asset and alert mapping by zone
- Document vault connected to each space
RESULTS
Full Digitisation Without Drawings in 4 Weeks
- Fully digitised and operational in < 4 weeks
- Live fault and occupancy monitoring
- Preventive maintenance made spatially actionable
- Legacy building upgraded without drawings
