Harnessing Drone Technology for Highway Construction

In recent years, the integration of drone technology in civil engineering has revolutionized the industry, offering unprecedented capabilities in data collection, monitoring, and analysis. This article delves into a case study on the Pristina-Gjilan Highway to illustrate the profound impact of drones on infrastructure projects.

Drones have transitioned from military applications to becoming essential tools in various sectors, including construction. Equipped with advanced cameras and sensors, drones can capture high-resolution aerial images and collect data that was previously challenging to obtain. This technological leap facilitates accurate data collection and analysis, enhancing decision-making processes and project outcomes.

The Pristina-Gjilan Highway project in Kosovo serves as a prime example of drone application in civil engineering. The use of a Phantom 4 RTK drone, along with Agisoft Metashape Professional and ArcMap desktop 10.5, enabled comprehensive monitoring and comparison of construction progress against project designs.

The project involved capturing aerial photographs of the highway segment using the Phantom 4 RTK drone. These images were processed with Agisoft Metashape Professional to generate digital surface models and orthophotos with a resolution of 4.46 cm/pixel. The processed data were then analyzed using ArcMap desktop 10.5 to compare the as-built conditions with the original project designs.

 

The high-resolution orthophotos and digital models allowed for detailed analysis of various construction elements, such as drainage channels, retaining walls, and the highway body. Significant discrepancies were identified between the designed and actual states, highlighting areas that required adjustments.

Drainage Channels: Changes in the atmospheric water drainage channels were observed, necessitating updates to the archival project. These changes were attributed to measurement inaccuracies, poor design, and local geological conditions.

Protective Gabion Walls: The protective wall with gabions, designed to span 300 meters, was found to be only 172.6 meters in the field. Monitoring continues to ensure that the wall meets the projected length as construction progresses.

The use of drones in this project provided several advantages:

The Pristina-Gjilan Highway case study underscores the transformative potential of drones in civil engineering. By integrating drone technology, projects can achieve higher accuracy, efficiency, and safety. This approach not only improves current practices but also sets a new standard for future infrastructure projects. As drone technology continues to evolve, its applications in civil engineering will undoubtedly expand, driving further innovation and improvements in the field.

Continued research and development in drone technology will address existing limitations and explore new applications in civil engineering. The integration of Geographic Information Systems (GIS) with drone technology holds promise for even more sophisticated data analysis and project management capabilities.

Incorporating drones into civil engineering practices represents a significant step towards a more efficient, accurate, and safe construction industry. The Pristina-Gjilan Highway project exemplifies the benefits and potential of this cutting-edge technology, paving the way for its widespread adoption.

By leveraging the power of drones, civil engineers can ensure better planning, execution, and monitoring of construction projects, ultimately leading to improved infrastructure and enhanced quality of life.
