Detailed Topographic Surveys

Side-by-side view of a roundabout design in CAD and 3D model.

Detailed topographic surveys provide the accurate site information required for design, planning and development projects.


Using Leica survey equipment, we capture buildings, roads, services, vegetation, contours and other site features to create reliable survey data for architects, engineers, builders and developers.


Available in both 2D and 3D formats, our surveys deliver the accurate existing-condition information needed to support informed project decisions and successful project outcomes.

3D Laser Scanning

3D laser scanning captures millions of survey-grade measurements to create a highly detailed digital representation of existing conditions.


This technology enables the rapid collection of accurate data across complex sites, buildings and infrastructure while reducing the need for repeat site visits.


Terratwin delivers registered point clouds, suitable for architectural, engineering, BIM and asset management applications. Laser scanning is particularly valuable where accuracy, detail and site accessibility are critical.


Measured Building Surveys

3D CAD and Revit Modelling

Terratwin provides measured building surveys for residential, commercial, industrial and heritage projects throughout South Australia.


Combining conventional surveying techniques with advanced 3D laser scanning technology, we capture accurate existing-condition information tailored to project requirements.


Deliverables can include floor plans, roof plans, elevations, reflected ceiling plans, sections and BIM-ready datasets to support design, renovation, documentation and asset management projects.

3D CAD and Revit Modelling

3D CAD and Revit Modelling

Using survey-grade point cloud data, we create accurate 3D CAD and Revit models that integrate seamlessly into architectural, engineering and BIM workflows. 


Our models provide a reliable digital representation of existing structures, reducing design risk and improving project coordination.


Whether supporting renovations, heritage documentation, asset management or new developments, our modelling services provide the accurate information required to confidently progress design and construction projects.
