Making Earthworks 10X Faster

There’s a construction boom taking place across Qatar, and Arcadis is helping make it possible. The global engineering consultancy, which has over 27,000 employees based in 350 offices across the world, leads infrastructure development projects across Qatar, helping the country meet ambitious construction goals for the 2022 FIFA World Cup™ and for its 2030 National Vision.

Arcadis recently had the opportunity to put drones to work on a project of a massive scale: Contract 2 of the Orbital Highway in the city of Doha, a 14-lane road with 5 vehicle lanes and 2 dedicated truck lanes going in each direction. The Orbital spans 46 kilometers in total, and construction will be finished in 2018.

Arcadis was the lead designer of the Orbital, but their emerging drone operations presented a new business opportunity for this project. Their client, Qatari Diar Vinci Construction (QDVC, a joint venture company between Qatari Diar and Vinci Construction Grands Projets), wanted fast, accurate volumetric calculations for the earthwork spread throughout the entire roadway. “Our main deliverable for this project was volumetric calculations,” said Paul Kawuma, Innovation and Infrastructure BIM Manager at Arcadis.

Putting drone surveying to the test

Arcadis is a pioneer of using drones for engineering purposes in Qatar, and they thought that the size of the site and specific goals of the project would be a perfect fit for a drone survey. However, in order to win the project to survey the whole highway, they first had to prove that that they could get accurate volume calculations from drone surveys compared to traditional methods.

They chose a 3-acre area which was representative of the rest of the site, and performed a test survey with both methods. Arcadis decided to use the 3DR Site Scan drone data platform, with its high-resolution 20.1MP Sony R10C and Autodesk integration, in order to bid on this project.

As Paul said, “When we were preparing the business case and looking for a drone solution, Site Scan stood out compared to alternatives. We liked how easy it was: we could trace the area to survey using the tablet, then the drone will fly itself and capture the images. We could then upload the images directly from the drone to the cloud—which plays a key role in streamlining the drone to data process—and they start processing into orthomosaics and other deliverables automatically. Even though we were just starting out with this new technology, it was easy to get into the workflow.”

Ultimately, the traditional survey took 3 hours, while the drone survey took just 20 minutes. The drone captured substantially more data points too: while the traditional method captured 197 points, Site Scasn were able to capture 1,539,964 points.
