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

TESTIMONIAL

What Our Clients Said

“We thought our building was too old to go digital. The scan-based twin gave us a 21st-century platform without needing 21st-century drawings.”
