Abstract
Summary:
Heritage Buildings perform a pivotal and very important role in the history of the nation, culture and express the wealth of it. In order to expand life and increase the strength of heritage buildings, conservation is a very important process for future generations to keep knowledge about how humans lived in the past ages. Conservation of heritage buildings keep values of the countries cultural, Moreover, conservation enables heritage buildings to be given a second life and a profitable investment. Conservation of Heritage Building projects is considered the complex process that is associated with many factors that affect the decision of selecting restoration technique. A structured questionnaire was distributed among the experts in the field of Heritage Building conservation projects in order to determine the factors affecting the decision of restoration technique. A statistical analysis was carried out on the collected questionnaire to reach the importance and weights of each factor. In Heritage Building conservation projects, Value engineering (VE) is considered a fertile area for the implementation of multi-criteria decision making (MCDM) due to the existence of different alternative combinations that are studied by the decision maker to reach a satisfactory restoration technique. The research presents the development of Heritage Building Restoration Model (HBRM) that uses MCDM technique which assists Heritage Building owners to decide on the best restoration technique in order to conserve and adapt the reuse of their Heritage Buildings. The model implements Simo's procedure to determine the importance and weights of the factors that influence the decision of restoration and rehabilitation of Heritage Buildings. The Weighted-Sum decision making technique is applied on a case-study of Heritage Building conservation project in order to reach the final preferences, rank the alternative restoration techniques and consequently come-up with the most appropriate restoration technique. Sensitivity analysis is performed to determine the most critical factors of the key-list. Additionally, several scenarios are investigated to verify that the most important factor of the key-list does not necessarily be the most critical factor. A real-life Heritage Building conservation project was then considered to verify the developed HBRM model. The final decision of HBRM is tested against the experts' decision in that project. It was concluded that the final decision obtained from the proposed HBRM matches the one that was implemented in the real project.
