Engineering Pre-Design Site Surveys
Before construction can commence on a major project, a full site survey by a licensed surveyor is preferable and in many cases essential. However, pre-design work can often be informed much more quickly and cost-effectively using a pre-design site survey.
Queensland Drones is not a licensed surveyor, but we do use many of the tools of a licensed surveyor to provide GIS-grade survey data for site planning, cut and fill estimates, quantity surveys, tenders, etc. Our UAV Lidar Surveys for engineers and surveyors can deliver very accurate DEM, DSM and surface models, usually <5cm precision without GCPs and often <2cm precision with surveyed GCPs.
We can work with your trusted surveyor or we can introduce a trusted surveyor we’ve worked with previously to ensure you can confidently rely on the data we provide.
In the example shown below, a full site survey by a licensed surveyor would have taken weeks and cost tens of thousands of dollars. Even a traditional drone survey using photogrammetry or Lidar would have taken many weeks to deliver, as the site is in the flight path of a busy airport and would have required a long CASA review and approval process.
Using advanced GIS techniques, Queensland Drones was able to provide a pre-design data set (leveled contours, DEM and orthographic image) for this site in less than a week and with real world precision measured in centimeters. We also provided a detailed report on accuracy and how it was established.
This pre-design survey was delivered using a combination of LiDAR data, high resolution satellite imagery and precise location data collected by a registered surveyor (in just a few hours on the site).
