Civil Engineering Structures start to deteriorate as of the very point in time at which their construction is completed. This simple fact has led to the need for their conservation and the development of a number of techniques taking best advantage of modern technologies to facilitate the management of their conservation to being generally accepted. Conservation is customarily conceived as the sum of all operations and interventions which are necessary in order for a structure to be maintained with the functional, resistance-related and even aesthetic characteristics with which it was designed and built. All of these operations and works as a whole can be divided into three phases: Inspection, Assessment and Maintenance. GEOCISA performs Inspection and Technical Assessment works on all types of structures: bridges, buildings, walls, breakwaters and docks, etc.
