3D contour and detail surveys in Brisbane
Precise measurement of existing site features and levels, topography, structures and services for a seamless project design.
Our 3D site surveys deliver the essential spatial data architects, engineers, and builders rely on for accurate residential, commercial, and infrastructure design.
We use precise 3D laser scanning and 360° imagery to capture all visible surfaces and features of your site with high accuracy and level of detail.
You can pick and choose what you need in the 3D model and drawings, or go with our standard inclusions tailored to your type of project.

3D Contour & detail survey FAQ.
A contour and detail survey records the levels, contours, features and services on your site so your design team knows exactly what's there. Our surveys are captured in 3D with laser scanning, so you get a 3D model of the site as well as the typical site plan drawing in DWG and PDF.
Yes. It's also called a site survey, feature survey or detail and level survey. It shows the levels, contours, features and services on your site. The survey is used when planning and designing new builds or redevelopments.
Using traditional survey methods, a surveyor picks up individual points (edge of road, building corner, etc.) and draws lines and points, most commonly in 2D. This method can be slow and prone to missed features. If any additional information is required, another site visit is needed.
At ProSurvey, we use 3D laser scanning to measure the whole site, capturing millions of points across every visible surface. You get a high‑resolution digital copy of the site, buildings and features. We use those scans to produce our comprehensive site BIM surveys. Because we've scanned the whole site, we can answer many follow‑up questions from the data, which reduces return visits, and your design team can check dimensions remotely.
Our standard inclusions are ground levels on a 5 m grid with contours every 0.25 m, changes in grade, retaining walls, buildings and floor levels, footpaths, roads, kerbs, fences, trees and all ground surface types, plus visible services. Your quote lists the survey area and every feature we'll pick up, and you can add or remove items to suit your project.
A 3D BIM model (`.rvt` / `.ifc`) and a contour and detail site plan in DWG and PDF. Every survey also includes a measurable 360° walkthrough and the registered point cloud.
We use an external utility locating contractor to locate services on site and include their findings in our survey.
We can use existing site control or establish our own. Surveys can be georeferenced to MGA2020 coordinates and AHD levels from GPS or the nearest government Permanent Survey Mark. We'll specify this in your quote based on your project requirements.
Yes. We can overlay the approximate boundary position from the digital cadastre (DCDB), or locate boundary pegs and reference marks on site for higher accuracy. Your quote states which option is included.
If no pegs or reference marks are found on site, you will need to engage a Registered Cadastral Surveyor to carry out a Boundary Identification Survey.
We do not offer boundary surveys and will not place any boundary pegs on site as part of our survey.
Yes. Because everything is scanned in 3D, we can include building footprints, floor levels, roof and awning heights, and even full building models when your project needs them.
It depends on the site area, terrain, vegetation, access, and whether you need boundaries or underground services. Send us the address, a marked-up survey area and your requirements, and we'll provide a fixed-fee quote.
