Earth Drones in Construction

Construction projects have become more complex and larger.

Monitoring large construction sites is one of the most difficult aspects of construction project management. Each stage of a construction project has its own key monitoring areas. Project managers must monitor the work of field workers as they dig in the ground to lay the foundation. Project managers must monitor field workers who are working on scaffolding during the stage of ground construction. So it is necessary to use drones in construction.

The long-term benefits of using drones are significant. Having depth in your reporting is significant.

Orthomosaic maps

Earth Drones can provide georeferenced orthomosaic maps that can be loaded into Google Earth or GIS (Global Information Systems) for measurement purposes that need accuracy of levels of 1 centimeter. These maps also allow the contractor and their clients to monitor construction progression over time. This can also be useful for the contractor to analyze progress and conduct fault finding throughout the construction process. Accurate measuring on ortho maps include straight line, area and volumetric measurement options.

3D point clouds

3D point cloud models can be used to make accurate measurements in 3 dimensions e.g. wall heights, roof angles and gradients, change (development) detection modeling, volume scaling and more. These models can be used in AutoCAD and other engineering software.

3D MODELS

3D models provide high resolution navigable digital worlds of construction progress that can be used by contractors and their clients to visually represent construction progress in 3D. This makes it very easy for contractors to digitally send progress timelapses of development over time to their clients anywhere in the world.

Digital Surface and terrain models

Digital terrain and surface maps can be generated from drone data and then be used to calculate cut and fill measurements and material stock pile volumes with accuracy levels of down to 1cm per pixel. These maps can also be used to monitor potential erosion on site and areas where runoff may occur and much more.

Change detection model

3D models provide high resolution navigable digital worlds of construction progress that can be used by contractors and their clients to visually represent construction progress in 3D. This makes it very easy for contractors to digitally send progress timelapses of development over time to their clients anywhere in the world.

Change detection models using point cloud data is a very powerful way of determining where materials have been removed or deposited over time by comparing multiple different models. In the above example, the areas represented in red show deposition of materials around the building site in meters (tree growth at the base of the model is also represented). Areas highlighted in blue represent areas where materials have been removed. These models are a great way to represent cut and fill changes over time as well.
