FDH Infrastructure Services

Field Investigations

FDH’s field investigation services are backed by the firm’s innovative nondestructive test (NDT) methods, which minimize the need for invasive, cost-prohibitive excavation and drilling. While FDH specializes in field investigations of tower structures, the company’s advanced NDT capabilities have been applied extensively to engineering analyses of bridges, dams, levees, and wind turbines.
