1. Development of an algorithm that uses an Excel® file containing data taken from a database to read the Cartesian x, y, and z coordinates of a linear infrastructure. 2. Determining additional calculation scripts for the proper dynamic positioning of the bridge elements from the point layout. 3. Producing a layout based on the latter. This method yields a parametric BIM model whose properties vary dynamically based on the input fields provided into the database. This makes it possible to apply the code repeatedly for any bridge and ensure continuous control over the bridge. Any updates or changes would therefore be reflected semi-automatically on the model, requiring only an update to the read-out file that was extracted from the database. Once the methodological approach has been defined, the authors proceeded with the development phase of the complete code, which was created by combining the following code components: • Script for creating a layout from known coordinate points. • Script for dynamic assignment of opera parts. • Script for automated parameter reading from the database. After the creation of the individual code blocks, all the components are united to make a single, comprehensive script. A semi-automatic algorithm for creating BIM models using information available from the data in the bridge database is defined and created by the combination of all the previously mentioned components, as summarized in Figure 4.

4. Results The research context in which the proposed methodology is applied has as its main objective the creation of a procedure for the classification of bridges and viaducts on a territorial scale through the simplified and expeditious estimation of their structural health. The following sections demonstrate the use of the methodology for the automatic calculation of the attention class within this framework. The attention class is a synthetic indicator that represents the structural health of the bridge and is based on guidelines from the Italian Ministry of Infrastructure and Transport.
