Fundamentally, building safety management needs to be implemented differently according to various building planning conditions and its construction process, building use, and management methods. Recent literature regarding a spatial and environmental safety management system argues for prioritizing high-risk facilities and its risk management, and applying differentiated measures corresponding to the facilities. Building safety management should also be differentiated by risk level from the initial design stage to the building use stage, and appropriate safety management measures need to be applied. In particular, the internal conditions related to building safety (e.g., building use, size, floors, structure, and building age), as well as external conditions of building users, local and surrounding environment need to be comprehensively considered in building safety management. Furthermore, the efficient operation of management also needs to be considered in relation to the current building safety management system.
This study suggested the Risk Assessment and Safety Determining Tool (RAST) as an objective tool to diagnose the risk level of buildings and to offer safety management directions. The risk level of buildings was measured based on aspects that determine the building characteristics, such as building use and size, structure and finishes, the site environment, and building age. Based on the risk index and safety management index, RAST determines the safety management level and safety management index, and helps to establish a management plan according to the results.
