Scan to BIM

3D Laser Scanning & Scan-to-BIM

We combine high-precision 3D laser scanning with point cloud processing and BIM/Revit modelling to capture accurate as-built conditions of existing structures, plants and substations. This allows owners and EPC contractors to detect clashes before fabrication, verify dimensions against AFC drawings, and cut costly rework and tie-in risk on brownfield and retrofit projects.

How It Works

1. Field data capture: We deploy terrestrial laser scanners (e.g. Leica, Cyclone REGISTER 360) to capture millions of measured points across the site, producing a dense, millimeter-accurate point cloud.

2. Registration and georeferencing: Individual scans are registered and georeferenced into a single coordinate system tied to site control points, so the model lines up with existing drawings and site data.

3. BIM/Revit modelling: The point cloud is used to build an intelligent 3D model in Revit, capturing structural, mechanical, electrical and piping elements as they actually exist in the field.

4. Deliverables: Clients receive the registered point cloud, the Revit/BIM model, clash reports and as-built drawings, ready for design, retrofit or facility management use.

Our Equipment & Technology

• Laser scanners: Leica RTC360 and Leica RTC500

• Processing software: Leica Cyclone REGISTER and Cyclone 3DR

• In-house software: our own engineering team also develops additional in-house tools to support and streamline our Scan-to-BIM workflow

Why It Matters for Owners and EPC Contractors

• Eliminates repeat site visits and reduces field verification time

• Reveals clashes and space conflicts before fabrication or construction

• Provides a reliable as-built baseline for plant expansion, retrofit and maintenance planning

• Supports accurate quantity take off and progress tracking against AFC drawings

Completed Projects

• 3D Survey for 22+14 Substations  - EGAT, 2025. Laser scanning, georeferencing and Revit modelling of 22+14 high-voltage substations for the Electricity Generating Authority of Thailand.

• 3D Survey for 10+7 Substations - EGAT, 2026. Laser scanning, georeferencing and Revit modelling of 10+7 substations for the Electricity Generating Authority of Thailand, extending Papada's substation survey scope.
