We deploy terrestrial laser scanning (TLS) to establish a precise digital baseline for engineering and construction. Our reality capture process converts physical site conditions into high-fidelity point clouds for spatial coordination, fabrication detailing, and structural verification. By validating as-built geometry against design intent, we mitigate fit-up risks in complex retrofits and provide objective analysis of construction tolerances, deflection, and member alignment.

​

DATA AQUISITION & CONTROL​

​

• Terrestrial Laser Scanning (TLS): High-definition capture of structural frames, slabs, façades, and MEP plant areas.

• Survey Control: Registration to project datums (local grid, UTM, benchmarks) for georeferenced accuracy.

• Complex Registration: Cloud-to-cloud and target-based optimization for multi-level assets and stair cores.

​

PROCESSING & GEOMETRY EXTRACTION​

​

• Point Cloud Cleaning: Segmentation and noise removal to isolate structural elements from transient site clutter.

• Scan-to-BIM: Modeling of key geometry - slab edges, grids, beams, and columns - for Revit/Tekla integration.

• 2D Generation: Extraction of floor plans, sections, and elevation profiles directly from scan data.

​​

CONSTRUCTION VERIFICATION QA/QC​

​

• Deviation Analysis: Heat map comparison of as-built conditions against design models or record drawings.

• Slab Analysis: Floor Flatness (FF) and Levelness (FL) reporting, camber checks, and deflection mapping.

• Site Verification: Validation of member plumbness, connection locations, and bolt patterns prior to fabrication.

• Clash Detection: Clearance checks between existing structure and proposed fit-outs or mechanical/electrical routing.

• Scan-informed structural assessments where as-built geometry differs from design

• Comparison of as-built point clouds to design models or 2D drawings

• Support for forensic work using scan-to-scan comparisons (movement, distortion, settlement)

​​

​DELIVERABLES​

​

• Point Clouds: Registered datasets (E57, LAS, RCP) with accuracy reports.

• Visualization: Web-based viewer for remote site access, dimensional take-offs, and team collaboration.

• CAD/BIM Assets: 2D deviation plots and 3D reference models formatted for structural analysis.
