ADF's transportation achievements include bridges, pedestrian bridges, highway overpasses and transit systems. Some of these projects requires high-caliber engineering and fabrication of heavy components, and their structures often have to be installed in challenging environments, such as over fast-current rivers or deep canyons, calling for special heavy equipments. Long-span girders, heavy steel pieces and use of barges and derricks are part of the daily routine of such project installation.

Transit systems have their own specific requirements, centered specifically around ride comfort, passenger security and speed, which means rigorous fit of steel components that hold together multidirectionally.
