Drone survey of 70 acre earthworks project
We used RTK/PPK drone technology on an earthworks project to measure various stockpiles across the site quickly and safely achieving sub 30mm accuracies.
The 2D and 3D digital data was used to understand the volume of materials onsite but they can also be used for month end reporting and scheduling. The digital data can be used to track, map, and measure earthworks on pre and post stripping surveys.
The health and safety benefits of using drone technology for earthworks are huge as people are not put at risk with heavy machinery moving around site. Capturing the digital data from a drone survey can be done in a controlled and safe environment away from site dangers.
The survey grade accurate 2D/3D digital data from drone technology is going to play a huge part on the High Speed 2 (HS2) project enabling the four main civils contractors to make accurate and regular earthworks calculations, (reducing risk and improving cash flow) while also using the data to enhance internal and external communication with the project teams and client. As-build vs design analysis can also be carried out at any phase in the construction process.
Aerial LiDAR can be used to carry out topographical surveys of areas with dense vegetation varying from grass/brambles through to mature trees and shrubs.
We also have the ability to carry out stockpile measurements e.g. agricultural products, aggregates, metals etc. within a warehouse or storage unit using terrestrial 3D laser scanning.
The survey-grade accurate 2D and 3D digital data can be easily integrated into existing workflow processes as the data can be produced in various CAD, BIM and GIS formats e.g. dwg, dxf, xyz, las, laz, obj, geotiff and e57.
