As-Built Documentation

Accurate documentation of completed work for verification, compliance, and future use

As-built documentation provides a precise record of completed construction and infrastructure projects — ensuring alignment between design, execution, and final results. Using drone-based LiDAR, photogrammetry, and GNSS positioning, highly accurate spatial data can be captured efficiently across complex project environments.

FROST delivers reliable as-built documentation supporting quality assurance, project handover, compliance, and long-term asset management.

Why as-built documentation matters
Accurate documentation reduces risk and improves transparency throughout construction and infrastructure workflows.
Key benefits include:
  • Verification of completed work against design models
  • Documentation for handover and compliance
  • Reduced risk of disputes and rework
  • Reliable datasets for future maintenance and upgrades

Drone-based workflows provide efficient coverage and consistent data quality across the entire project area.

Applications
As-built documentation supports a wide range of projects and industries:
  • Infrastructure projects such as roads, railways, and utilities
  • Construction and site development
  • Energy and power installations
  • Municipal and public works
  • Asset documentation and lifecycle management
Data acquisition and workflow
FROST combines multiple technologies to ensure accurate and complete project documentation:
  • Drone-based LiDAR for precise geometry
  • Photogrammetry with high-resolution imagery
  • GNSS and ground control for accurate positioning
Typical workflow:
  • Data capture of completed or ongoing construction
  • Processing into point clouds and terrain/surface models
  • Comparison against design models when available
  • Generation of structured documentation and deliverables
Comparison, validation, and construction monitoring

Comparison and validation

A central part of as-built documentation is comparing reality with planned design.

FROST enables:
  • Design vs. as-built comparison
  • Detection of deviations and discrepancies
  • Documentation of tolerances and compliance
  • Clear visualization of differences

This provides a reliable basis for quality assurance, validation, and project acceptance.

‍

Monitoring during construction

As-built documentation can also be performed continuously throughout the construction phase.

This allows:
  • Tracking of construction progress
  • Early detection of errors or deviations
  • Documentation at key project milestones
  • Improved communication between project stakeholders
Deliverables
We provide structured deliverables adapted to project requirements and documentation standards:
  • Point clouds (LAS / LAZ)
  • Digital Terrain Models (DTM) and Surface Models (DSM)
  • 3D models and visualizations
  • Comparison reports (design vs. as-built)
  • GIS- and CAD-ready datasets
  • Optional web-based viewers for easy access and collaboration
