3.2. Geographic Information System (GIS) Each bridge's geographical location is made easier by GIS, which links them to a referenced geographical coordinate system. It is possible to display georeferenced point icons in the GIS environment, which gives a precise geographical representation. All the bridges in the regional area can be quickly visualized and geolocated thanks to the GIS catalogue, which also makes it possible to handle vast amounts of data and information related to bridge assets. The GIS catalogue incorporates data about the bridge's deteriorated condition and structural health, including dates of on-site inspections and the findings of monitoring assessments using satellite InSAR technology. The need to efficiently gather, process, visualize, and update geospatially linked data regarding bridge structures led to the idea to create this advanced bridge catalogue as a GIS-based tool. Two information levels serve as the foundation for the GIS catalogue: a first level that includes broad information and a second level that has more in-depth information, including details on structural features. A growing number of data sources are used to collect the information, which is then updated and upgraded with information from non- destructive technologies and site inspections. An example of GIS-generated output highlights attention classes by showcasing bridges within a regional portfolio, as shown in Figure 3. The bridge icons are color-coded based on the attention class they belong to: • Red denotes intense attention. • Orange, medium attention. • Yellow, low attention.

3.3. Creation of a parametric BIM models To model a bridge using parametric BIM, the following procedures must be followed:
