Abstract
The incorporation of protocols in heritage building preservation is important for the definition of preventive conservation actions. Such integration is needed to avoid restoration actions and to promote preventive maintenance instead of corrective maintenance actions. This paper presents the application of an innovative digital management system using artificial intelligence that can quantify the suitability of a sample. This kind of application can support the maintenance management of buildings and minimise human error in data collection. The fuzzy system showed slight differences between the members of the expert panel during the in-situ visual inspection. These results indicate that, despite differences between various experts’ evaluation of a building, the proposed digital method helps minimise the uncertainty in the results. The paper highlights input variables, which present high dispersion (load state modification, fire and occupancy), and input parameters, which present low dispersion (preservation, roof design and overloads). Fuzzy systems can adequately manage the uncertainties associated with different experts’ assessment of sample that present constructive homogeneity. This study can give advantages to stakeholders during the inspection, diagnosis and evaluation stages in the improvement of mitigation policies focused on preventive maintenance programs dedicated to the resilience of heritage buildings, specifically churches emplaced in Chile.
Highlights
The culture of a nation is influenced by buildings or structures that have historical significance
Seven professional experts participated in the in-situ visual inspection of the selected heritage churches in Santiago de Chile
R17 presents a medium–high dispersion by the experts’ valuation; this input variable must be examined in detail in future works; (iii) Four case studies (41.6% of the sample) need priority intervention
Summary
The culture of a nation is influenced by buildings or structures that have historical significance. Buildings have had special meanings among people for economic or social reasons. In this context, churches have been permanent meeting places in Western culture. Communities have developed around them, and they remain in the memory of several generations as centers of development of their lives. For this reason, some churches have been declared heritage buildings. Some churches have been declared heritage buildings Their historical and cultural values are recognized, and these structures should be maintained and preserved to extend their service life. Khodeir et al (2016) stated that heritage buildings are crucial for the human perception of culture and identity through time
