Automated Construction Site Monitoring

How DJI Dock and Drone Harmony Enable Daily Quality Control

Bloomville is a large construction project in Switzerland, developed by HRS. The project combines modern residential architecture with a strong focus on digital construction workflows.

Because part of the development consists of privately owned apartments, individual interior design changes are frequent. This increases the need for precise, up-to-date site documentation and reliable quality control.

The Challenge: Accuracy, Speed, and Documentation

Traditional construction monitoring relies heavily on manual site inspections, measurements, and photo documentation. These methods are:

• Time-consuming

• Resource-intensive

• Prone to delays between data capture and evaluation

In fast-moving construction phases, errors often become apparent only after corrections have become expensive — for example, after concrete has been poured.

The Solution: DJI Dock + Drone Harmony

To address these challenges, the Bloomville project uses DJI Dock combined with Drone Harmony and the TEDAMOS platform by Terradata.

The DJI Dock enables fully automated daily drone flights across the entire construction site. Drone Harmony manages flight planning, execution, and cloud-based processing.

Each mission:

• Covers the full site autonomously

• Takes approximately 12 minutes

• Captures 800+ high-resolution images

This creates a consistent, complete dataset every day.

Quality Control Before It Gets Expensive

Daily automated flights allow teams to:

• Verify the positional accuracy of construction elements

• Detect deviations early

• Make corrections before costly construction steps

This proactive approach significantly reduces rework and improves overall construction quality. At the same time, the system creates a complete, gapless record of the construction site history.

Drone Harmony creates a complete, gapless record of the construction site history.

Compliance and Operational Safety

Operating an automated drone system required a SORA operational authorization.

While complex, the process helped establish clear safety procedures, roles, and response plans. As a result, daily drone operations are:

• Safe

• Compliant

• Clearly structured

All involved pilots and stakeholders know exactly what to do — even in exceptional scenarios.

From Images to Actionable 3D Data

After each flight, Drone Harmony Cloud automatically triggers data processing.

Using advanced photogrammetry algorithms on TEDAMOS high-performance servers, the captured images are transformed into:

• Digital elevation models

• Orthophotos

• Point clouds

• Textured 3D surfaces

Thanks to integrated RTK positioning, the resulting models achieve centimeter-level accuracy — even without ground control points.

From Tool to Asset Management Component

The final 3D models are delivered directly to the project manager, enabling:

• Faster decision-making

• Transparent communication

• Increased trust among all stakeholders

At Bloomville, drones are no longer just tools — They are an integral part of the digital asset management workflow.

Conclusion

By combining DJI Dock, Drone Harmony, and TEDAMOS, this project demonstrates how automated drone operations can transform construction monitoring:

• Higher quality assurance

• Significant time savings

• Complete and reliable documentation

• Greater confidence for developers and investors

Drone Harmony enables construction teams to monitor smarter.
