Heritage Evaluation: restoration plan through HBIM and MCDA

Abstract

This study is prompted by the activity carried out within a EU funded project (WARMEST)[1] whose goal is to analyze monuments’ degradation due to factors such as climate change and growing number of tourists, create a model to describe and anticipate the phenomena, and put in place a user-friendly Decision Support System that will help in setting preventive maintenance plans. As part of the project, we had the chance to study in depth the degradation at the Patio de Los Leones, the core of the world-famous site of the Alhambra and Generalife, which attracts to Granada in Spain where they are located over 2 million tourists per year. The paper aims to define a new methodology to assess the level of urgency to restore the 124 columns of the Patio de Los Leones (Alhambra). It is not easy to identify all the factors affecting the columns’ deterioration and to establish which should be restored first. Our approach is to collect all the data regarding the decay factor and use multi criteria decision aid methods such us the Analytic Hierarchy Process in order to create a hierarchy among all columns according to their decay. We also will create an HBIM model of the Patio del Los Leones in order to optimize the management and maintenance of the columns. HBIM model can also optimize the data management and enable to compare results (in this case data about columns decay) over time.

Research on Pathology Information Management of Educational Architectural Heritage Based on Digital Technology: The Case of James Jackson Gymnasium

“…Ferraz et al (2016) [23] analyzed the literature related to building pathology detection technology and methods and concluded that there is currently no management system for quickly obtaining pathology information and that the importance of building a pathology information management system is emphasized. Acampa et al (2020) [24] used the HBIM model to analyze the aging factors and maintenance management of columns in the Patio de Los Leones in Alhambra, Spain. Israeli scholars used threedimensional laser scanning technology to collect data on the severely damaged walls of Jerusalem's historical buildings and drew flat, vertical, and cross-sectional views of the walls, which provided a data basis and repair plan for subsequent wall protection.…”

Assessment of Disused Public Buildings: Strategies and Tools for Reuse of Healthcare Structures

“…Several tools have been developed in the last decades to support decision-makers to assess the effectiveness and quality of retrofitting interventions, especially in the field of multicriteria evaluation methods [16]. Concerning design quality, several research studies have been carried out in Europe [17,18], especially in Italy, with the Siva-SISCo evaluation method [19,20], while EPiQR [21,22], developed at the EPFL, has been found particularly fitting to evaluate the environmental impact of retrofitting existing buildings.…”

Hbim Work Methodology Applied to Preventive Maintenance: A State-of-the-Art Review

“…Subsequently they are validated on a case study so that their suitability or need for improvement can be evaluated [52], [56]. On other occasions, HBIM repositories are used to help in the decision-making process by defining hierarchies in the information levels that allow organizing the importance of deterioration and favoring the establishment of priorities [57].…”
