This work focuses on the development of a methodology for the complete reconstruction of the 3D geometry of a concrete bridge. 3D scanning technology was selected as the most apt to the task as it provides very detailed geometrical informations. A dedicated carriage system for a compact and lightweight laser scanner has been designed and built as a first prototype to be used on laboratory as well as future on-field tests. A first assessment of the design constraints has been carried out, based on the general goal of implementing a system able to be used with existing inspection vehicles with minimal modifications. The specific electronic system for management and control of the carriage system and the management of the associated tracking system has been also designed and realized. Some preliminary tests have been performed at Politecnico di Milano University campus to assess the viability and analyze the performance of the early design choices.
