“…The fib Bulletin n°17 [1] describes visual inspection as the survey methodology most cost-efficient, which quickly provides an overview of the condition of the structure and makes it possible to report back immediately. It is the cheapest inspection type and, with experienced staff, it is also sufficient reliable.…”

This paper shows the comparisons between different methods of visual inspection used in European Countries. These methodologies are applied to the deck bridge located near Cagliari, along the SS 195 road to Capoterra. From a strategic point of view, this structure plays a key role ensuring a direct connection to different structures related to industrial and local productions and to an important touristic district. This is a prestressed concrete bridge in an aggressive marine environment, which in October 2008 was hit by a flood that caused subsidence in the foundations. The aim of our inspection is to obtain a real measure of the vulnerability through different procedures and to determine which is the best method able to give objective results.

In this paper, the computerised acoustic attenuation tomography imaging has been analysed, implemented and then performed for non destructive testing of a stone masonry. The tomography implies that a ill posed linear equations system has to be solved, in order to determine the attenuation distribution inside the tested structure, thus highlighting the presence of anomalies. The algebraic problem of the attenuation tomography inversion has been deepened, and the solving algorithm has been numerically developed. The entire process has been implemented in an automated procedure that allows the user to easily obtain a map of the attenuation distribution in the tomographic section of the object.
