Revolutionizing Façade Inspections at One Zabeel: How FEDS Delivered Excellence Through Expertise

We’ve always believed that technology is only as powerful as the people operating it. The recent façade inspection project at One Zabeel in Dubai stands as a testament to this philosophy. The iconic 300-meter-tall structure, with its glass façade and unique architectural design, presented significant challenges that required more than intelligent equipment—it demanded expertise, adaptability, and precision. Our team rose to the occasion, completing the inspection efficiently and delivering a detailed report that exceeded expectations.

The Challenges of Traditional Inspection Methods

Before diving into how we executed the project, it’s important to highlight the inefficiencies of traditional façade inspection methods. Rope access has long been the standard approach, but it comes with numerous pitfalls:

1. Safety Risks: Rope access inspections involve workers physically rappelling down the side of a building. While safety measures are in place, the inherent risk remains high. Workers are exposed to potential falls, adverse weather conditions, and even fatigue from prolonged physical exertion.
2. Limited Visibility: Inspecting a full glass façade manually often results in missed issues. For example, cracks or defects visible from the exterior may not be detected from the interior vantage point. This limitation can leave critical problems unaddressed, leading to costly repairs later.
3. Time Consumption: Rope inspections are painstakingly slow. A single side of a building can take an entire day to inspect. For a complex structure like One Zabeel, this could mean weeks of work, disrupting building operations and increasing costs.
4. Cost Inefficiency: With manual labor-intensive methods, the costs of rope access inspections quickly add up. The need for specialized workers, safety equipment, and extended timelines makes traditional inspections a less appealing option.

How Drones Overcome Traditional Challenges

Our approach to the One Zabeel project was rooted in overcoming these traditional limitations while maximizing efficiency and safety. Here’s how our drone-powered solutions delivered:

1. Enhanced Safety: By replacing rope access with drones, we eliminated the need for human workers to rappel down a 300-meter-tall building. Our pilots were able to operate the drones from a safe distance, minimizing risk while maintaining full control of the operation.
2. Comprehensive Data Collection: Equipped with advanced payloads, our drones captured high-resolution imagery and thermal data that surpassed what manual inspections could achieve. These tools provided the clarity needed to identify cracks, defects, and temperature variations that might indicate gaps or panel issues.
3. Faster Turnaround: The entire inspection, which would have taken weeks with traditional methods, was completed in just two days. With 16 carefully planned flights, our team covered the entire façade, including hard-to-reach areas like the underside of the bridge connecting One Zabeel’s two towers.

Project Execution: Leveraging Expertise and Adaptability

The height of One Zabeel presented unique challenges, including GPS signal instability at 300 meters and the wind funnelling effect in the “vengeance area” beneath the bridge connecting the towers. These factors required meticulous planning and quick problem-solving.

Our pilots, accustomed to operating in complex environments, adjusted flight angles to minimize reflections from the glass façade. They also navigated the turbulence and GPS interference with precision, ensuring the drones captured accurate data without compromising safety. The environmental conditions—the region’s heat and humidity—added another layer of complexity.

The Role of Advanced Payloads

For this project, we used the M300 drone equipped with a PhaseOne P3 payload and an DJI H30T thermal payload. The medium-format PhaseOne camera offered clarity with its 100 MP resolution, allowing us to capture seven glass panels in a single image. This efficiency reduced the number of flights required and ensured that even the smallest defects were identified.

Our pilots chose a 35 mm lens for optimized area coverage and carefully adjusted the drone’s positioning to comply with public area constraints.

Delivering Results

The final deliverable was a detailed report highlighting the condition of One Zabeel’s façade. Our data processing team transformed the high-resolution images and thermal data into actionable insights, providing the client with a comprehensive overview of potential issues. This level of precision and clarity would have been impossible with traditional methods.

By addressing the inefficiencies and risks of rope access inspections, we delivered a solution that was safer, faster, and more cost-effective. At FEDS, we believe in pushing the boundaries of what’s possible, and this project was yet another step forward in redefining how inspections are done.
