How Drones are Being Used in Construction and Infrastructure ?

As we saw above, different types of drones can be used in many different ways, which will help streamline many construction operations. So how exactly can drones be used in the construction industry?

Types of Drones Used in Construction and Infrastructure

Different projects and different construction sites require different types of drones to get the job done properly. When it comes to drones, the first thing that comes to mind is quadcopter drones , which are the most common type on the market. However, there are other types of drones that are also being used in the construction industry. Let's have a look:

Multirotor Drones

Multi-rotor drones are most commonly used by professionals and hobbyists. They usually have 4-8 rotors and have a flight time of about 30 minutes. Like helicopters, multi-rotors do not require a lot of space to take off and land and can hover in the air, making them ideal for tasks such as inspections and field surveillance. With their compact design, they are generally foldable and easy to store and transport. Multi-rotor drones are very easy to handle, and even inexperienced pilots can learn to fly in just a few minutes. However, this type of drone has very limited flight time, speed, and load capacity, so they are not suitable for large-scale sites and projects with high accuracy requirements.

Fixed-Wing Drones

Fixed-wing drones look like airplanes, but they are much larger than multi-rotors. These drones are more stable than multi-rotor drones and can fly in harsh environments. Fixed-wing drones can usually float for hours in the air and fly faster than multi-rotors, enabling them to be commonly used to map large areas of land. Fixed-wing UAVs are not as versatile as multi-rotor drones in the construction industry because they need a long runway to take off and land, which may not be convenient around construction sites. Except for that, fixed-wing drones are more difficult than multi-rotor drones and often require specialized flight training to fly them.

Helicopter Drones

Helicopter drones have one or two rotors with blades whose flight principle is the same as that of a manned helicopter, using rotating rotors to generate lift and thrust. With only a single rotor, helicopter drones use more energy efficiently, fly longer, and are more efficient to fly than multi-rotor drones. The downside to using these drones is that they are difficult to fly because there is only one main rotor and the slightest imbalance can cause a collision with something in the environment.

Hybrid Fixed-Wing

There are also hybrids of fixed-wing and multi-rotor drones on the market, which have the high efficiency and long endurance of fixed-wing drones but can also take off and land vertically like multi-rotor drones. But this VTOL drone model is expensive and hard to fly, requiring more flight training.

Drone Outputs of Construction Drones

Using the data collected during one flight of the construction drone, the post-processing software created the following different deliverables：

Orthomosaics

Drone photogrammetry takes several orthophotos during the flight and stitched them together in post-processing to create a highly accurate orthomosaic map. Each pixel of this map contains geographic information that helps crews measure the exact distance to the job site.

3D Textured Models

3D Texture models are a "mesh" of several triangular polygons that, along with the texture file, accurately reflect the topography of your job site. These models combine a bird's eye view of ground conditions with accurate positioning data, allowing construction and earthwork teams to examine and measure their sites and plan for the future.

3D Point Clouds

3D point clouds can be generated from drone imagery. Each of its points references a distinct feature on your site, which is accompanied by geospatial coordinates and color information. In construction and civil engineering, point cloud modeling simplifies the measurement process for complex projects that include features such as roads, bridges, and buildings.

Digital Elevation Model (DEM)

Unlike textured models, digital elevation models (DEMs) show only the surface, with no texture data. Using raster datasets to represent the topography of a particular size and color to show differences in elevation, DEMs allow you to visualize the shape of the terrain at your site, aiding in drainage planning, line of sight coverage, foundation soundness, and more.

RAW Images

The raw image is the unprocessed original image taken by the drone, which provides more detail and is useful for equipment inspection and analysis.

Thermal Imaging

Thermal imaging uses a spectrum of colors to represent different temperatures, the warmer color the higher temperature. By viewing these videos, operators can spot a range of building defects not visible to the naked eye, providing insight into thermal bridging, water leaks, and defective insulation.

Video Footages

Visible light and infrared videos record everything on the job site, from criminal activities to security issues. By reviewing these images, and annotating them, you visually share these project-building issues with your project team for immediate resolution.
