Then, the second phase concerns the plotting from the C.U.G.RI. platform of the inspection outputs and, in terms of “Relative Defectiveness” (Dr), to be re-entered, via an additional ad hoc developed VPL script, into an editable BIM environment for archiving purposes and the graphical visualisation of the state of health of the infrastructure (see Fig. 2).

2.2. Description of the bridge components for inspection purposes The Surveillance Handbook catalogues bridges, underpasses, and viaducts through a dual coding system: an alphanumeric codification (STONE CODING) and a computer key (AGE KEY) generated by the AGE software for each infrastructure. The so-called STONE code consists of 10 digits according to the scheme “XX YY ZZZZ K J” that identifies the “Global Structure Number” (see blue area of the code in Fig. 3). The infrastructure can consist of one or more “Partial Structures” – numbered “11” – and has to be additionally broken down into “Structural Sections” and “Components”. As shown by Table 1, each Structural Section is identified by a code consisting of two capital letters (“VV”); the same applies to Components (“YY”), while, in the fifth column, there is the “defect evaluation form” (DM 578/2020 - All.B) associated with it (see yellow area of the code in Fig. 3). In order to automate the unique assignment of the inspection forms, we provided further information relating to the material (“MAT”) of the components and add another parameter (“Typology”) to characterize the structural behaviour of some specific elements.
