Arriving at this Hawaii ranch property, the scope was immediately clear: document everything. Main dwelling, accessory dwelling unit (ADU), pond, and the spatial relationships between all structures for comprehensive site planning.
The Project: Complete Ranch Property Documentation
This Hawaii ranch presented an interesting documentation challenge:
Main dwelling requiring precise as-built measurements
Existing ADU needing integration into site planning
Natural pond feature with irregular boundaries
Property boundaries and access routes
Elevation changes across the ranch landscape
Traditional surveying methods would have served this project well—they've been the foundation of property documentation for generations, and rightfully so. However, the sheer volume of data needed and the tight timeline called for a more comprehensive approach.
Technology Advantage: Speed Without Compromise
Using professional-grade 3D LiDAR scanning, we captured the entire property in a single day: Main Dwelling Documentation
The existing home was captured inside and out, providing precise measurements for any future renovation planning or permitting requirements.
ADU Integration Planning
The accessory dwelling unit's exact positioning relative to the main house, setbacks, and utilities was documented for future development considerations.
Pond and Landscape Features
The natural pond's irregular shape and surrounding topography were captured in complete detail—something particularly valuable for drainage analysis and landscape planning.
Deliverables: Design-Ready Documentation
The comprehensive scan data was processed into multiple formats for different uses:
Detailed site plan showing all structures and features
Individual building floor plans for both dwelling and ADU
Topographic mapping including pond contours
3D visualization models for planning presentations
CAD files compatible with design software
The Value: Quality and Completeness
Modern scanning technology doesn't replace the expertise and judgment that traditional surveying provides—it enhances it. The result is documentation that's both faster to obtain and more comprehensive than conventional methods alone could deliver.
For this Hawaii ranch, that meant capturing not just the obvious features, but the subtle relationships between structures, the exact pond boundaries, and elevation data that might affect future development—all in a single site visit.

Property Scanning: Common Questions
Can you capture both indoor and outdoor spaces in one visit?
Yes, our 3D scanning captures complete property documentation—interior spaces, exterior structures, and landscape features—typically in a single site visit.
How do you handle irregular features like ponds or natural terrain?
LiDAR excels at capturing irregular shapes and natural features with precision that's difficult to achieve with traditional measurement methods, providing accurate contour mapping for design planning.
What formats do you deliver for architects and planners?
We provide multiple file formats in including Revit, ArchiCAD, AutoCAD, Sketchup and more.
