Drone in Construction & Infrastructure: Benefits, Uses, and Case Studies
The use of drones in the construction industry has surged by a staggering 239% year-over-year, surpassing all other commercial sectors. Over the last few years, commercial drones have significantly impacted and revolutionized construction. Their aerial dominance and data collection abilities make them a practical tool for video and imagery, offering advantages ranging from construction site mapping and site security to remote monitoring.
Ever wondered how drones can be utilized in the construction industry? Are you considering starting a drone project for your construction company? In this article, we'll explore the key benefits and main applications of construction drones, the different types of drones used in construction, and provide a list of some of the best drones for construction purposes based on our research, along with real-world case studies.
Let’s jump right in.
**Benefits of Drones in Construction and Infrastructure Projects**
The impact of drones in construction has already transformed the efficiency and accuracy of the industry. Here are the primary benefits that drones bring to construction and civil engineering companies:
1. **Fast and Accurate Data Collection**
Obtaining detailed mapping and surveying data is crucial for every phase of a construction project. Traditional methods using land-based equipment are time-consuming and labor-intensive, especially in rugged terrains. Drones can perform the same or better survey work in 60% to 70% of the time, reducing the risk to personnel.
2. **Cost and Time Saving**
Reducing costs is a priority in any sector, and drones are a cost-effective solution compared to mobilizing entire inspection teams. For instance, inspecting tall buildings with cracks can involve renting a crane and hiring a team, whereas drones can capture the necessary images safely and at a fraction of the cost.
3. **Increased Construction Safety**
Previously, construction workers climbed rooftops to inspect damages and completed vertical inspections from scaffolding, posing risks. Drones now allow for safe inspections from a distance, ensuring the safety of workers and providing real-time diagnostics.
4. **Improved Communication**
Traditional communication via radios and cell phones often leads to errors. Drones improve communication by up to 65%, offering real-time video data that allows everyone connected to see what’s happening and what needs to be done, fostering more efficient information exchange.
5. **Easy Construction Progress Monitoring**
Drones enable companies to monitor construction sites regularly, allowing for timely adjustments and corrections to keep projects on track. The data collected can be quickly shared with all stakeholders, ensuring everyone is aligned with the project’s progress.
6. **Effective Construction Marketing**
High-quality images and videos captured by drones serve as excellent marketing material, showcasing the grandeur of construction sites from various angles, helping companies build a modern brand.
**Disadvantages of Drones in Construction**
Despite their numerous benefits, drones also come with challenges:
1. **Weather Dependency**
Compared to conventional aircraft, drones are more susceptible to weather conditions. Windy conditions can disrupt their flight path, affecting data reliability. However, some high-end drones are more stable in adverse weather.
2. **Legal Uncertainty**
While drone usage is common, regulations are constantly evolving, making it difficult to obtain necessary permits. Urban areas pose more regulatory challenges than open spaces.
3. **Vulnerability to Wildlife**
Drones can attract wildlife attacks, especially from large birds of prey, which might collide with or capture drones.
4. **Skill and Knowledge Requirements**
Flying drones requires expertise to avoid accidents. Training or hiring professionals is essential for accurate data capture.
5. **Security Risks**
Drones, like other connected devices, are vulnerable to hacking, posing potential security threats.
6. **Malfunctions and Software Issues**
Like any machinery, drones can malfunction due to software issues or mishandling, leading to accidents. Proper maintenance and training are crucial.
**Types of Drones Used in Construction**
Different construction projects require different types of drones:
1. **Multirotor Drones**
Commonly used by professionals, these drones have 4-8 rotors and can hover in place, making them ideal for inspections and field surveillance.
2. **Fixed-Wing Drones**
Resembling airplanes, these drones are more stable and can cover larger areas, though they require a runway for takeoff and landing.
3. **Helicopter Drones**
These drones use a single rotor, providing efficient flight but requiring specialized training to operate.
4. **Hybrid Fixed-Wing Drones**
Combining the efficiency of fixed-wing drones with the versatility of multirotor drones, these are costly and challenging to fly.
**How Drones are Being Used in Construction?**
Drones are transforming various aspects of construction:
1. **Initial Site Survey and Measurement**
Drones provide more accurate terrain data and generate detailed maps.
2. **Workflow Monitoring**
Drones offer a broad view of the construction process, sending real-time data to ground stations.
3. **Equipment Tracking**
Equipped with sensors, drones can detect building defects and electrical problems.
4. **Remote Monitoring and Progress Reports**
Clients can track project progress remotely, enhancing trust in the project’s success.
5. **Complete Inspection of the Project**
Drones can access hard-to-reach places, improving safety and efficiency.
6. **Generation of Advertising Material**
Drones capture high-quality images and videos, aiding in marketing efforts.
7. **Risk and Safety Management**
Drones monitor teams, ensuring compliance with schedules and site conditions.
**Drone Outputs of Construction Drones**
Post-flight processing creates valuable deliverables:
1. **Orthomosaics**
Highly accurate maps combining multiple orthophotos.
2. **3D Textured Models**
Reflecting topography with precise positioning data.
3. **3D Point Clouds**
Representing distinct site features with geospatial coordinates.
4. **Digital Elevation Models (DEM)**
Showing surface topography without texture data.
5. **RAW Images**
Unprocessed images useful for detailed analysis.
6. **Infrared Video Footages**
Highlighting temperature variations, identifying hidden issues.
7. **Optical Video Footages**
Recording visible site activities for immediate resolution.
**Which Drone is Best for Construction?**
The JOUAV CW series drones stand out due to their versatility and advanced features:
- **VTOL Capability**
- **Multiple Payload Options**
- **Fast Speed and Large Coverage**
- **High Accuracy and Resolution**
- **Safe and Easy Operation**
**Drone in Construction Case Study**
JOUAV drones have been deployed in various projects, including road maintenance surveys in Malaysia and reservoir mapping in China, demonstrating their effectiveness in diverse scenarios.
**How Much Do Construction Drones Cost?**
Construction drones vary in price from $2,500 for basic models to $75,000+ for high-end industrial drones.
**Future Uses of Drones in Construction**
The future of drones in construction looks promising, with possibilities of fully unmanned site work, digitized monitoring, and even contributions to Mars exploration.
This transformation in construction practices is just the beginning.
