Why Accurate Progress Documentation Matters
Modern construction moves fast — and so do the expectations. General contractors, civil engineering firms, developers, and industrial project managers all need accurate, defensible, and timely documentation to keep projects on schedule, reduce rework, and maintain transparency with stakeholders.
Traditional ground‑based photos simply can’t keep up.
That’s where LiDAR, photogrammetry, and 3D modeling redefine what “progress documentation” means.
ARO Aerial delivers precision‑grade aerial data that gives your team a complete, measurable, and verifiable record of every phase of construction — from site prep to turnover.
📡 What LiDAR & 3D Modeling Capture
1. High‑Accuracy LiDAR Scans
LiDAR provides dense, survey‑grade point clouds ideal for:
- Earthwork tracking
- Cut/fill analysis
- Pre‑ and post‑grading verification
- Structural progress measurement
- As‑built comparisons
Typical deliverables:
- Classified point clouds
- Digital terrain models (DTM)
- Digital surface models (DSM)
- Contours
- Volume reports
Why GCs and civil firms rely on it:
LiDAR penetrates vegetation, captures complex geometry, and maintains accuracy even in low‑texture environments where photogrammetry struggles.
2. Orthomosaic Mapping (High‑Resolution 2D)
Orthomosaics provide a true‑to‑scale, georeferenced top‑down view of the entire site.
Use cases:
- Weekly/monthly progress tracking
- Site logistics planning
- Material staging verification
- Safety compliance documentation
- RFI support
Deliverables:
- GeoTIFF orthomosaics
- Web‑based interactive maps
- CAD‑ready exports
3. 3D Modeling & Digital Twins
Photogrammetry‑based 3D models and LiDAR‑enhanced meshes give stakeholders a fully navigable digital representation of the site.
Applications:
- Clash detection support
- Structural progress visualization
- Owner updates
- Pre‑bid walkthroughs
- As‑built documentation
Deliverables:
- Textured 3D meshes
- Point clouds
- BIM‑aligned exports (RVT, IFC, OBJ)

❓ FAQ
How accurate is LiDAR for construction?
Depending on sensor + workflow, LiDAR typically achieves 2–5 cm vertical accuracy, ideal for earthwork and as‑built verification.
How often should progress documentation be captured?
Most GCs prefer weekly or bi‑weekly, while civil firms often request phase‑based captures.
Can aerial data integrate with BIM?
Yes — we provide IFC, OBJ, LAS, and RVT‑compatible exports for seamless BIM alignment.
Do you provide volume calculations?
Absolutely. Cut/fill, stockpile volumes, and material movement reports are standard deliverables.
