How Cadmap works
Four steps from first call to final drawing
Our own surveyors on site with Leica instruments, and our own team drawing the results — so the data you receive is data we can stand behind.
- 01
Discuss your project
Tell us the site, the drawings you need and the deadline you are working to. We advise on the right survey type and specification, then return a free written quotation — usually within 24 hours.
- 02
Survey & data collection
Our CSCS-carded, CRB-checked surveyors attend site with Leica robotic total stations, GPS, 3D laser scanners, GPR and CCTV drainage equipment, tying everything into OS grid and datum where required.
- 03
Process & analyse
Survey data is processed in SCC, Geosite Survey Office, Leica Cyclone and Wincan, then drawn in AutoCAD or modelled in Revit so that it matches your project's layering and output standards.
- 04
Deliver accurate data
You receive fully checked drawings, models, point clouds or condition reports in the formats your design team works in — with our team on hand for queries and revisions.
Who we work with
Survey data the whole project team can build on
Architects
Existing-condition floor plans, elevations, sections and topographical bases you can design straight onto, drawn to RICS specification.
