Drones #1: Revolutionizing Construction – The Power of Drones

Our series of articles on drones kicks off this week with an analysis by Stephan KRAJICEK, Team Leader, Mechanical Projects in SYSTRA Canada’s Rolling Stock Division, of the various advantages of using drones for construction projects. Stephan is one of the winning teams in SYSTRA’s SPARK Challenge 2022.

In the ever-evolving world of technology, drones have emerged as a game changer in various industries. One sector that has particularly benefited from their capabilities is construction. These unmanned aerial vehicles (UAVs) are transforming the way construction projects are planned, executed, and monitored. From surveying and mapping to inspections and site monitoring, drones are revolutionizing construction practises, improving efficiency, and enhancing safety.

In this blog post, we will delve into the numerous applications of drones in construction and explore the impact they have had on the industry.


Traditionally, conducting land surveys and creating accurate topographic maps required significant time, resources, and manual labour. With drones, this process has become much more efficient.

Equipped with high-resolution cameras, LiDAR sensors, and GPS technology, drones can quickly and accurately capture aerial images and data, enabling precise mapping and surveying.

This allows construction professionals to gain valuable insights into the terrain, identify potential challenges, and develop informed construction plans.


Inspecting construction sites for safety, progress monitoring, and quality control is a critical aspect of any project. Drones provide an efficient and cost-effective solution for conducting inspections. Equipped with high-definition cameras, thermal sensors, and other specialized equipment, drones can closely examine structures, rooftops, and hard-to-reach areas.

This enables inspectors to identify potential issues, track progress, and ensure compliance with safety regulations, all without the need for manual inspections that can be time-consuming and risky.


Drones equipped with live-streaming cameras offer real-time monitoring capabilities, allowing project managers to remotely monitor construction sites. This proves particularly useful for large-scale projects or those located in remote areas.

Real-time monitoring enables supervisors to track progress, identify bottlenecks, and make informed decisions promptly. Additionally, by monitoring worker activities and equipment usage, drones help optimize resource allocation, minimize downtime, and improve overall project efficiency.


Safety is a paramount concern in the construction industry, and drones play a crucial role in enhancing safety measures. They can be deployed to inspect hazardous areas, such as tall structures, rooftops, or confined spaces, reducing the need for workers to be exposed to potentially dangerous environments.

Moreover, drones equipped with thermal sensors can detect heat signatures and identify potential fire hazards, enhancing fire prevention measures. By reducing the risks associated with manual inspections, drones contribute to a safer working environment for construction personnel.


Drones provide a comprehensive visual documentation tool that captures the construction process from start to finish. By regularly capturing aerial images or videos, drones create a detailed record of the project’s progress. This documentation proves valuable for project stakeholders, including investors, clients, and regulatory authorities.

Additionally, sharing drone-generated visual data enhances communication among project teams, making it easier to collaborate, identify challenges, and align objectives.


Drones have undeniably revolutionized the construction industry, offering an array of applications that improve efficiency, safety, and communication. From aerial surveying and mapping to inspections, real-time monitoring, and progress documentation, these unmanned aerial vehicles have become indispensable tools in the construction sector.

As the technology continues to advance, we can expect further integration of drones into construction practises, leading to even greater productivity gains, enhanced safety measures, and improved project outcomes. Embracing the potential of drones is no longer a choice but a necessity for construction companies aiming to stay ahead in today’s fast-paced and competitive industry.


In the next article, we will be looking at how drones are transforming the railway industry.
