Tunneling

Work with Trimble Access Tunnels and leverage TBC’s point cloud and reporting tools for tunnel survey workflows and deliverables.

• Create CAD cross-section diagrams.

• Parametrically design tunnel shape templates with dynamic cross-section interface.

• Intuitively design set-out positions like blast holes, rock bolts, canopy tubes, and more for in-field stake out and as-built via Trimble Access Tunnels field software.

• Analyze designed or as-built tunnel meshes to produce customized heat map comparisons and assign as-built points from point cloud data to create 3D as‑built inspections.

• Generate comprehensive as-built reports to convey excavation overbreak/underbreak estimates, TBM ovalisation and wriggle checks, and more.

• Perform as-built to design and as-built to as-built inspection using total station or point cloud data to verify shotcrete thickness, excavation shape, and final lining position.

Use point cloud or total station data for tunnel survey deliverables.
