3D Laser Scanning & Boundary Surveying for High-Stakes Sites
Licensed California surveyor-led laser scanning for floor flatness, structural steel and anchor bolt verification, field measure for custom fabrication, and as-built documentation, plus forensic boundary surveying, for architects, engineers, contractors, fabricators, developers, and attorneys across San Francisco, the East Bay, the North Bay, and Northern California.
Book a Free 15-Minute Scope Meeting
Before You Ask for an Estimate
Serious projects deserve more than a blind number. Book a short meeting with the licensed surveyor, share the project context, and get a scoped estimate when there is enough information to price the work responsibly.
What Happens in the Meeting:
Project Risk Review
We'll identify where bad existing-condition data, incomplete records, slope issues, or unclear boundaries could create delays.
15-Minute Surveyor Consultation
Speak directly with a Licensed Professional Land Surveyor about the right survey, scan, exhibit, or as-built scope.
Recommended Deliverable Path
Walk away knowing whether you need point clouds, CAD plans, 3D linework, ADA exhibits, boundary research, or something simpler.
Modern Surveyor-Led Scanning
Reality capture tied to survey control.
We work with architects, engineers, developers, attorneys, institutions and owners on buildings and sites with complicated existing conditions. Every project starts with a scope meeting so the deliverable matches the risk.


01
Point cloud capture
Dense existing-condition data captured once for the building, site, route, or disputed area.

02
Scan-to-CAD production
Floor plans, sections, elevations, surface data, or 3D linework built around the actual scope.


03
Surveyor interpretation
Boundary, ADA, construction, and legal context added where a scan alone is not enough.

Focused B2B Survey Niches
Built for teams that need existing-condition certainty.
Complex buildings, high-liability measurements and difficult boundaries: the work where being wrong costs far more than getting good data.


Architects, engineers, contractors, owners
Reality Capture for AEC Teams
Renovations, retrofits, and tenant improvements fail when teams design from stale drawings or partial field notes.
Point clouds, CAD plans, 3D linework, and a web viewer link your whole team can use.

Contractors, fabricators, steel erectors, engineers
Construction Verification for Builders & Fabricators
An out-of-flat slab, a misplaced anchor bolt, or an opening that does not match the drawing turns into rework once the next trade arrives.
Floor flatness maps, steel and anchor bolt verification, and field measure for custom fabrication, on survey control.


Contractors, owners, geotech, attorneys
Deformation Monitoring & Movement Surveys
Excavation, shoring, dewatering, and adjacent construction can move neighboring buildings, walls, and slopes — and discrete prism points miss what scanning captures across the whole structure.
Scan-based baseline plus repeat epochs, with deformation comparison across the full surface, not just survey points.

Architects, engineers, owners, developers
Site Plan & Stamped Permit Surveys
Many Bay Area jurisdictions — SF, Oakland, Berkeley, Peninsula — require a current site survey wet-stamped by a licensed PLS before plans can be submitted.
Stamped boundary + topographic site plan surveys delivered as CAD-ready base files for permit-ready design work.

Preservation architects, churches, institutions
Historic Preservation & Adaptive Reuse
Older churches, civic buildings, and custom structures rarely have accurate drawings, and their irregular details are expensive to measure by hand.
Non-invasive point cloud documentation for restoration, facade work, structural coordination, grants, and archives.


Owners, architects, contractors, counsel
ADA Ramp & Route Verification
Small slope, landing, and transition errors can turn into failed inspections, rework, or accessibility claims.
Survey-grade as-built measurements and exhibits for compliance review, correction, and liability defense.


Developers, attorneys, architects, HOA teams
Condo Conversions & Interior As-Built Scanning
Converting an existing building requires dependable interior, exterior, unit, common area, and boundary information — and old plans rarely match what is built.
3D laser scanning of interiors, boundary coordination, CAD-ready as-builts, and mapping support for conversion teams.

Attorneys, owners, developers, insurers
Forensic Boundary & Litigation Support
Disputed lines, encroachments, and contradictory records need more than a quick field measurement.
Historical record reconstruction, defensible survey analysis, exhibits, and expert witness support.
Bay Area Surveyor Search Focus
3D laser scanning and boundary surveying for Bay Area projects.
Contour Survey is built for serious commercial, legal, design, and property teams searching for a licensed surveyor who can combine modern scanning deliverables with defensible California boundary surveying.
3D laser scanning surveyor for Bay Area design teams
High-density terrestrial laser scanning for architects, engineers, contractors, owners, churches, and institutions that need point clouds, scan-to-CAD drawings, 3D linework, and as-built documentation before design decisions get expensive.
Site plan surveys for Bay Area permit submittals
Wet-stamped site plan surveys for San Francisco, Oakland, Berkeley, and Peninsula jurisdictions that require a current survey signed by a licensed California PLS before plans are accepted. Boundary plus topographic base maps delivered as CAD-ready files for architects and engineers.
Difficult boundary surveys for Bay Area properties
Licensed boundary surveying for hillside lots, irregular Bay Area parcels, post-1906 SF blocks, fire-rebuild areas, missing monuments, and conflicting record evidence — including Records of Survey and Corner Records when the work needs to be on permanent file.
Boundary surveying for property lines and disputes
Property line location, encroachment analysis, forensic boundary work, and recorded survey documentation across the Bay Area and Northern California.
Deformation monitoring with 3D laser scanning
Scan-based deformation monitoring for adjacent-building risk, retaining wall and slope movement, settlement tracking, historic structures, and excavation-side monitoring. Capture full surface geometry on each epoch instead of relying on a handful of prism points.
Floor level surveys for structural engineers and HOAs
Independent, survey-grade floor level surveys where a structural report requires one to be performed by others and furnished to the engineer. Floor elevations on real control, a contoured elevation map, point data, and a stamped report. We perform no foundation repair, so nothing biases the numbers.
FEMA elevation certificates and LOMA requests
Signed FEMA Elevation Certificates for lenders, insurance agents, and building departments, tied to a published benchmark on the flood map datum. When the building sits at or above the Base Flood Elevation, we prepare and submit the Letter of Map Amendment, through eLOMA when it qualifies.
Condo conversion surveys with interior 3D scanning
Bay Area condominium conversion surveys built around 3D laser scanning of interiors. Complete unit, common area, and exclusive-use area as-builts, boundary coordination, and CAD-ready documentation for developers, attorneys, and HOA teams.
Local service area signals
Primary coverage includes the San Francisco Bay Area, East Bay, Peninsula, South Bay, Sacramento region, and nearby Northern California communities.
