3D scanning applications in structural design

The 3D scanning of existing structures has become easily available nowadays for practicing structural engineers. The number of specialised companies to perform this service is in a constant rise, while the financial burden of the service is considered to be good value for money. The current study aims to present different methods of using 3D scanning in structural design processes, showing the importance of integrating innovative and new technologies in the day-to-day life of structural engineers. The presented applications of 3D scanning in structural design include load evaluation of existing structures, in order to determine the real loading or load carrying capacity reserves; measuring the construction imperfection and execution errors; mapping the surroundings of new constructions, if these are connected to non-uniform surfaces of existing structures; damage evaluation of steel elements in the aftermath of a fire, in order to determine the elements that could be reused during the rehabilitation process of the structure. The authors present real life examples from their structural design practice, concerning evaluation of different existing structures and rehabilitation projects of historical monuments.
