Verticle Take-Off and Landing (VTOL)

The take-off and landing features of CW Series drones make them perfect for the construction industry, especially in places with gravel, debris, and cliffs. Thanks to the large vertical static elevation during takeoff and landing, these UAVs have better attitude stability compared to other VTOL drones.

CW-100 VTOL drone

Multiple Payloads

With payload capacity between 7kg and 20kg, the CW Series heavy lift drones are capable of carrying different payloads, such as 61MP full-frame camera, 30x visible and thermal cameras, and 360º LiDAR sensors ranging up to 1845 meters, for most mapping and surveillance requirements.

Fast Speed and Large Coverage

With advanced engines and power management modules, the CW series drones can last up to 840 minutes and fly at speeds of up to 135km/h. In a single flight, the CW-007 drone can map 2 times more area than a traditional fixed-wing drone and 15 times more than a multi-rotor. As some of the best long range drones available, the CW Series UAVs are well suited for large-area mapping and surveillance, as it has control range options of 50 km, 100 km, and 200 km.

Accuracy and High-Resolution

The CW Series drones are all equipped with some kind of GPS correction technology in combination with RTK and PPK modules. These RTK drones compute centimeter-level GPS data and embed the data into each image. Using the 61MP full-frame CA-103 camera, the CW Series drones deliver best-in-class GSD down to 5-8mm per pixel and absolute horizontal accuracy down to 1cm under optimal conditions. When carrying JoLiDAR-LR22S, the CW Series LiDAR drones can achieve down to 2cm vertical accuracy without GCPs.

Autonomous Navigation and Control

The flight of the JOUAV drones is fully automated and requires a little training. Flight planning is done through the FlightSurv and Eagle Map, the former for mapping and the latter for drone surveillance. Both are very simple and intuitive applications that can support the management of multiple missions and data post-processing at the same time.

These aircraft have forward-looking and down-looking obstacle avoidance radar, which helps them scan the environment and detect any obstacle along their router time-time. With a four-rotor level-flying layout and mutually independent power systems, this series of UAVs can activate the rotor blades to make a safe forced landing after a level-flying power failure, reducing the incidence of bombing accidents.

Drone Applications in Construction

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?

1. Initial Site Survey and Measurement

The use of drone surveying yields more accurate terrain data and generates more correct maps of the area. This is because drones can view the entire terrain extensively and accurately, without having to deal with vertical obstacles.

It is worth noting that drones do not replace established mapping techniques and manual processes, but they are widely used to improve the efficiency and accuracy of this step.

2. Workflow Monitoring

Accompanying the different stages between the beginning and the end of a job is part of the daily work of civil construction employees, especially engineers, architects, and construction technicians. The more details obtained at each stage, the greater the chance that professionals will identify problems and propose solutions.

Drones are important in these situations because they provide a broad view of the work team through a variety of perspectives. Since the connection is remote, the machine sends data in real time to a device on the ground (phone, computer, or tablet). Thus, the person in charge can examine and analyze the images obtained.

3. Equipment Tracking

Equipment failure is another common problem on construction sites. In addition to allowing general visualization of terrain, buildings, construction sites, etc., drones can also provide data that cannot be captured by the naked eye. For this, it is only necessary to equip the drone with special sensors and perform various activities, such as inspections through thermal imaging.

A thermal drone helps to identify the hottest areas, allowing operators to use this information to detect building defects or electrical problems on time. Then they can easily send the recorded data to the maintenance technicians of the equipment rental company for a faster and more accurate diagnosis before they arrive at the site.

4. Remote Monitoring and Progress Reports

The use of drones can also be applied to optimize the experience of clients who invest in real estate projects. The device contributes to providing images that show the planning and execution steps of the business.

With the images and videos obtained, professionals are able to create 3D electronic models and very realistic simulations of the business, allowing clients to track the progress of the project even when they are not on site. This helps reassure clients that their spending is being used effectively.

5. Complete Inspection of the Project

Drones for construction can also be used to check the condition of building elements. This step, in the traditional method, is usually quite time and labor-consuming, as it requires the use of cranes and many safety devices. However, since it is an essential service for preventing problems, it is a step that cannot be missed.

In these cases, drone inspection makes the whole process more agile and safer. With the implementation of support tools and attachments, they can detect electrical problems, leaks, and structural issues in advance.

The main advantage of drones in this case is that such devices can more easily access hard-to-reach places.

6. Generation of Advertising Material

Drones are capable of capturing images, as you already know. But after all, how can images captured by drones be used in residential buildings? These images can be used to create advertising materials for businesses to sell.

The device provides photos and videos that can replace the use of any professional camera and achieve angles that provide a very detailed assembly of graphic material.

In this way, the images obtained using drones can easily please your customers.

7. Risk and Safety Management

Taking care of occupational safety and health in the work environment is key to avoiding accidents. However, it is not always possible to guarantee that workers will use individual and collective protective equipment, or that a particular structure will be executed correctly. To avoid risks, construction companies usually employ supervisors.

In this sense, drones have the advantage of being able to monitor teams without incurring high operational costs. It is possible to combine two or more devices to verify that the workers are in compliance with the schedule, in addition to verifying the situation on the construction site.

Drone in Construction Case Study

Drone in Construction Case Study

JOUAV construction drones are used in all phases of the construction industry, from surveying new job sites to assisting in the ongoing maintenance of older buildings. Here are 5 case studies of drones in construction.

Use Case #1: Road Maintenance Survey in Malaysia

A Malaysian survey company used CW-25E and JoLiDAR-LR22S to collect detailed data on a local border road. The road is located in a tropical area with high precipitation and is prone to landslides. Over 10 days, the CW-25E had 14 flights and an average flight time of up to 180 min, obtaining 3D point clouds down to 5 cm/pixel GSD.

"Using these high-precision 3D point cloud data, we can analyze the topography and landforms, slope, slope direction, and other geological conditions around the highway. If we find signs of landslides, we can take protective measures in advance and notify local residents and relevant personnel," said John Wang, the engineer of this project.

Use case #2: Reservoir Construction Mapping in China

A Chinese land surveying company was hired to survey a 20.5 square kilometer area of a river valley in Zhejiang Province. Their client wanted to assess the feasibility of building a hydroelectric power plant in the area. The area to be surveyed had mountainous terrain, a rainy climate, and dense vegetation.

The company took the CW-30E and JoLiDAR-LR22S to a local school playground for the launch. Considering the huge elevation changes in the area, the CW-30E used ground-like flight and took images and geotagged them every three seconds.

CW-30E flew 76 kilometers in 1.3 hours and recorded 1,700 images. "We estimate that it would have taken over 300 hours to collect this much data on foot. the CW-30E did it in about 0.5 percent of that time," said David Lee, the project leader. "A review of the data showed that the surveyors' control markings were clear and accurate over a 7 kilometer by 3km area, the image geotagging was never more than 3cm in error. "

Types of Drones Used in Construction

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.

PH-25 multi-rotor drone used in construction

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 drone for construction

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.

Single-rotor helicopter drones used in construction

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

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 models

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.

Challenges of Drones in Construction

Challenges of Drones in Construction and Infrastructure

Drones can be a very useful tool for any construction project, but there are still some downsides to using drones in construction, from user privacy and security to legal issues and unfair use.

Weather Dependent

Compared to conventional aircraft, UAVs are lighter and smaller, which makes them more dependent on favorable weather conditions. For example, in windy conditions, drones can be blown off course, preventing them from maneuvering properly or collecting reliable data or imagery. However, some high-end drones on the market are more stable and can successfully withstand gusts of wind.

Legislative Uncertainty

While the use of drones has become commonplace, drone laws continue to evolve and change, leaving people struggling to get the required permits and delaying the progress of their projects. Those construction sites in large urban areas need to be especially aware of changing regulations and permitting procedures, but for open space and rural areas, drone permitting is usually not a big issue.

If your construction site is located in a large city, you may have a hard time determining what permits you need to obtain. At this point, you need to look for a company like JOUAV that specializes in drones and can help your company navigate these regulations.

Vulnerable to Wild Animals

Drones are vulnerable to wildlife attacks and their noise can affect wildlife. When drones fly in areas where there is a significant amount of wildlife, they can clash with an animal or crash into a tree. Large birds of prey like hawks often attack or even capture drones operating in their space.

Drones in construction are vulnerable to wild animals

Knowledge and Skill

Capturing accurate, high-quality data with drones is based on the pilot's superior flying skills. And as discussed earlier, inexperienced pilots can easily cause drone accidents. That's why an average construction worker needs comprehensive training or a third-party construction drone service to capture, process, and analyze site data.

Easy to Hack

Drones, like most connected devices, are vulnerable to hacking. According to security researchers, hackers can quickly attack the central control systems of some commercial drones from a mile away to access private information, destroy or damage files, and leak data to unauthorized third parties.

Software Issues or Malfunction

Like any machine, drones can suffer from malfunctions and software failures. Drones' signals are often scrambled by radio frequencies, which can lead to loss of control. When drones veer off course, they can hit people and their sharp blades can cause injury and death. In addition to this, the mishandling of drones can cause safety accidents or hazards. Therefore, it is important to have not only reliable software and hardware but also trained professionals to fly them.

Future Uses of Drones in Construction

Future Uses of Drones in Construction and Infrastructure

In the future, site work could become completely unmanned, with built drones taking care of the construction and surveillance drones monitoring the progress of the work. The surveillance drones can digitize the site and adjust the build drones during the construction process. These drones can even support automated control modes. Coupled with the ever-streamlined BIM workflow, the data collected by the drones can be quickly uploaded, processed, and made available in the cloud, which ensures that the entire team is on the same page.

The applications for UAV construction technologies are endless, from running electricity to repairing plumbing, the technology could disrupt the current construction industry. Scientists also believe that the development of drones will be able to form the basis for construction technology on Mars.
