12 unmanned systems inside October/November 2017 by Renee Knight B ased in Vienna, Strabag SE, covers all areas of the construction industry and is responsible for complex infrastructure and facility management projects all over the world. To help monitor and complete these projects more ef- ficiently and cost effectively, Dr. Thomas Gröninger and the team at Strabag AG in Germany decided to invest in unmanned aerial systems (UAS) technology earlier this year. After doing their research, it was clear Microdrones offered the best solutions to meet the company's needs. "The most important consideration for us was the camera system," Dr. Gröninger said. "Microdrones offers large cameras and a very good platform. The integration of Microdrones increased the efficiency of different pro- cesses in our company, which is why we invested in this very developed drone." Strabag also needed a secure, robust system that of- fered long f light duration, Dr. Gröninger said, which the Microdrones systems also provide. Over the last several months, the team has deployed the drones to monitor projects, plan construction sites, perform inspections and to compute highway surface volumes. Strabag first invested in the mdMapper1000 for its photogrammetry capabilities, and then the md4-3000 for its ability to carry heavy LiDAR sensors and mapping grade cameras. So far, not only has Dr. Gröninger been happy with the information his drones have been able to collect and how that information has helped to streamline operations, but also with the level of service Microdrones provides. Highway measurements One of the main ways Strabag uses the Microdrones sys- tems involves f lying over highways to complete surveys and compute surface volumes, Dr. Gröninger said. "We f ly the drone over a highway and the drone takes many pictures that have overlap. After the drone lands, we put the pictures into photogrammetry software to compute a 3-D point cloud," he said. "We can then make USER SHOWCASE FIELD TESTED, FIELD PROVEN. Photos courtesy of Strabag. MANAGING CONSTRUCTION SITES MICRODRONES Strabag, a European-based technology group for construction services, recently invested in Microdrones systems to more safely and effi ciently monitor construction projects, perform inspections and complete volume calculations. with
