Table 1 Diagnostic methods used in the case study
Method | Method characteristics | Advantages/disadvantages |
|---|---|---|
Visual assessment | Assessment of external surfaces and cracking patterns | + Low cost + Does not require specialized equipment − Results are qualitative |
Geotechnical investigations | Geological cores | + Assessment of differentiated subsidence rates of building foundations − High costs, especially with respect to deep bore holes |
Geometrical survey including H-BIM | Interactive model built by the use of the historical architectural and construction documentation, photogrammetric techniques, laser scanning, and other data obtained from the physical analysis of the building | + The possibility to understand, analyze, document, advertise and virtually reconstruct the whole structure + Enables also energy simulations, time, and cost calculations, and other functions that may improve the way to manage the maintenance and restoration processes − Complex and time consuming method |
