Comparative Analysis of Inspection and Diagnosis Tools for Ancient Buildings

Abstract

The survey and inspection of the state of conservation of buildings is understood as an active process of selecting information to support decision making in the rehabilitation of the built heritage. The development of new technologies applied to the integrated management of the built heritage resulted in digital tools able to support the technicians in on-site procedures. The purpose of this study was to analyse existing methods for the survey and inspection of the state of conservation of ancient buildings. It uses a qualitative methodology, focused on bibliographical survey and comparative analysis. Only methods with identical characteristics were considered: evaluation based on visual inspection of buildings with heritage value. This research shows that structuring information in computer systems is a solution to overcome the main problems pointed out in previous studies related to survey and inspection: expensive, time-consuming, inconsequential procedures and dispersed information. However, this is only valid if computer-based methods are adapted to the different geographic and chronological contexts. Future research may contribute to the development of a method that brings together this added value with a simple but objective way to diagnose the condition of ancient buildings with heritage value.
