Progress Monitoring and Reporting

Regular monitoring of construction progress is essential to ensure that projects stay on schedule and within budget. Drones can capture aerial images and videos, providing a comprehensive view of the construction site. This aerial documentation can be shared with stakeholders, helping identify any discrepancies, update schedules, and allocate resources efficiently.

Inspections and Maintenance

Inspecting structures like roofs, facades, and bridges can be challenging and dangerous for human workers. Drones offer a safer alternative by accessing hard-to-reach areas and capturing high-resolution images and videos. These visual inspections help identify potential issues, provide real-time data for decision-making, and reduce the risks associated with manual inspections.

Earthwork Volume Calculations

Accurate earthwork calculations are crucial for resource management and billing purposes. Drones can measure stockpile volumes, cut and fill calculations, and track earthwork progress with precision. This data allows construction companies to manage resources effectively and minimise disputes over billing and progress claims.

Communication and Collaboration

Effective communication and collaboration among various teams involved in a construction project are vital to its success. Drones provide real-time information through aerial images and 3D models, enabling teams to identify issues, coordinate tasks, and make informed decisions. This improved communication reduces errors and misunderstandings, ultimately leading to better project outcomes.

Safety and Risk Management

Construction sites can be hazardous, and ensuring worker safety is a top priority. Drones can monitor site safety, identify potential hazards, and ensure workers follow safety protocols. They can also be used to assess damage after accidents or natural disasters, reducing response times and mitigating risks.

Asset Management

Tracking and managing equipment and materials on a construction site can be challenging. Drones can help by monitoring inventory, reducing theft, loss, and downtime. This efficient asset management ultimately leads to cost savings and improved productivity.

Marketing and Promotion

High-quality aerial images and videos captured by drones can be used for marketing and promotional purposes, showcasing the project’s progress and finished product. This captivating visual content can attract potential clients, investors, and community support.

Environmental Monitoring

Construction projects must adhere to environmental regulations and minimise their impact on the surrounding environment. Drones can monitor environmental factors, such as erosion, vegetation growth, and wildlife activity, ensuring compliance and promoting sustainable practices.

3D Modeling and BIM Integration

Drones can capture data used to create accurate 3D models of construction sites, which can be integrated with Building Information Modeling (BIM) systems. This integration allows for better project management, coordination, and decision-making, leading to more efficient and successful construction projects.

Drones In Construction Case Studies

The Norwegian Public Roads Administration is utilising drones, specifically the WingtraOne VTOL drone, for road surveying to support their goal of achieving zero fatalities by 2024. The administration has significantly reduced project time and costs by implementing drone technology. Smaller projects that used to take up to five days with traditional survey methods can now be completed in just 15 minutes, while larger ones take only up to two hours. The WingtraOne offers enhanced coverage and efficiency compared to multirotor drones, enabling the creation of detailed point clouds for volume assessment and tracking of road construction progress. Additionally, the drone’s accuracy has proven cost-effective in reconciling contractor estimates, a process that is now faster and easier than before. WingtraOne’s recent updates, including improved wind tolerance and tipping prevention, have further enhanced its performance. As drone technology continues to evolve and improve, the Norwegian Public Roads Administration plans to expand its drone fleet and capitalise on the increasing benefits offered by the WingtraOne.
