Contemporary Mason Master’s Tacit Knowledge in Restoration Process of Architectural Works; Defining Process and Criteria for Architectural Repair in Southern Khorasan, Iran

Studies on monuments, repairs carried out on them, and the experience of the people who perform these repairs indicate a given method of repairing works. By focusing on the conservative thinking of contemporary master masons in southern Khorasan, the present study examines the “intervention process” for restoring the architectural heritage (decision-to-action). This research has been done qualitatively, field data collection method is applied, and data are collected through semi-structured interviews (conversation) with a group of contemporary master masons. The architects followed an achievable model while carrying out the restoration measures. Achieving the foundations and processes of intervention for the restoration of buildings is one of the major goals from the point of contemporary masonry masters’ views. What is the conservative thought structure that has developed from thinking to action for a restoration action will be one of the major questions. To achieve this goal, we utilize grounded theory. Finally, by comparing the extracted concepts presented the intervention process framework to restore architectural heritages. We can define this process with two critical sets. The first set is up to the intervention prerequisite, the "decision-making and diagnosis process". The next interval corresponds to the moment of intervention (repair or restoration), interpreted as a "planning and action process”.
