Astrea utilises the latest robotic Surveying Technology including GPS, 3D Scanning & Unmanned Aerial Vehicle (UAV) surveys. Astrea has a broad range of land surveying services which include:

Cadastral Surveys
Land and building subdivisions
Title boundary re-establishment surveys
Construction set out
3D modelling from point clouds
Unmanned Aerial Vehicle (UAV)
Feature and level surveys

3D Laser Scanning and Modelling

Depending on project requirements, laser scanning instrumentation may be used. 3D laser scanning and advances in high-dynamic range photography has led to quicker surveys, greater accuracy and easier interpretation of complex underground locations.

Advanced Technologies

Astrea utilises laser scanning technology alongside other data capture technologies such as Total Stations

Advanced Techniques

By using laser scanners, millions of survey points are captured in minutes - enabling large scale projects and areas of restricted access to be surveyed in a shorter time span. The level of accuracy, detail and speed also reduces the need to revisit a site multiple times.

Advanced Outcomes

The information captured is then used to create a number of deliverable including conventional plans, elevations, sections, fly-through, augmented reality and rendered models.​

CAD/Data Management

Astrea engages highly trained surveyors and draftsman, skilled in the operation of the latest software packages. These include:

12D Model, 12D field & 12D Synergy
AutoDesk Infrastructure Suite 2015 including:
  • AutoCAD
  • Civil 3D
  • Revit
  • Recap
  • Map 3D
  • Trimble Business Centre & Photography
  • Leica Cyclone v9
  • Rigorous Network Adjustment software

Vacuum Excavation

Our vacuum excavation is a non-destructive process that combines high pressurised water and a vacuum loaded holding tank to break up and cut the soil at a controlled rate. This process allows for quick, clean and precise excavations that require less backfill, labour, restoration, and most importantly minimal environmental impact than conventional digging methods.

What are the benefits of our vacuum excavation service?



Clean-cut, minimal post-excavation restoration activities

Environmentally friendly

Cost effective

Safely locates underground services

Less material removed i.e. less disposal, backfill and restoration
