Design From the Building That Exists, Not the Drawings You Inherited
Old drawings rarely match what was built, and the gaps show up later as RFIs, change orders, and redesign. FieldScan captures the building or site with 3D laser scanning, drone mapping, and land surveying, then delivers point clouds, Revit models, and CAD drawings checked against the scan, for AEC teams across San Diego County and Southern California.

What we deliver.
3D Laser Scanning Reality Capture
We capture existing conditions with survey-grade 3D laser scanners, producing high-density point clouds accurate to ±2mm. The foundation for BIM modeling, renovation planning, MEP coordination, and facility management.
Scan-to-BIM BIM Modeling
FieldScan converts registered LiDAR point clouds into Revit BIM models at LOD 200, 300, or 400 — modeled to the specs your team actually builds with, delivered in 2–4 weeks for typical mid-rise commercial buildings.
Drone Surveying & Inspection Aerial
FAA Part 107 aerial operations for site mapping, roof and facade inspections, earthwork volumetrics, and construction progress documentation. Georeferenced orthomosaics and 3D terrain models — no scaffolding, lifts, or site disruption.
Land Surveying Surveying
Boundary, topographic, ALTA/NSPS, and construction surveys prepared per California Professional Land Surveyor standards. We coordinate with local jurisdictions on permit requirements, title company specifications, and construction staking.
Facility Document Digitization Documentation
Turnkey digitization of scattered building records — paper blueprints, old PDFs, permit files, MEP diagrams — into a structured, searchable digital archive. Your team finds any document in seconds.
Technical Guides
Understanding Commercial Boundary Surveys
A commercial boundary survey establishes the exact legal perimeter of a parcel by comparing physical field evidence against recorded deed descriptions. Developers and architects rely on this verified boundary data to ensure new structures comply with local zoning setbacks and avoid encroaching on neighboring land.
Read guide →Topographic Surveys Explained
A topographic survey maps the physical features and elevation changes of a property. It provides the verified dimensional baseline required for civil engineering, grading plans, and architectural design.
Read guide →Asset-Tagged Digital Twin (LOD 500)
A technical guide to BIMForum Level of Development (LOD) 500 digital twins, detailing how survey-grade laser scanning and AI-assisted metadata extraction connect legacy facility documents to verified 3D geometry.

The right methodology.
FieldScan is a spatial data and building documentation company based in San Diego County. We provide 3D laser scanning, scan-to-BIM modeling, land surveying, drone aerial services, and facility document digitization for the AEC industry across Southern California.
We invest in survey-grade instruments and software — not shortcuts. Our Leica RTC360 scanners, robotic total stations, and enterprise drone platforms deliver the accuracy your architects and engineers require. The same data, in the format your team already works with.

Four steps. Clear timeline.
Some projects take a day. Others take months. Every one follows the same structured workflow — so you know exactly where things stand.
- 01
Scope
We define deliverables, access logistics, file formats, and timeline together. You receive a written scope and quote — typically within 24 hours.
- 02
Capture
Our field crew deploys with the right equipment for your project — laser scanners, total stations, drones, or a combination. We coordinate around tenants, occupants, and active operations.
- 03
Process
Raw field data becomes registered point clouds, BIM models, survey plats, or organized document archives. Every deliverable passes internal quality review before delivery.
- 04
Deliver
Final files delivered in your team's format — .rvt, .dwg, .rcp, .e57, PDF. Includes a walkthrough call to review deliverables. Revisions included.
