Full safety inspection and full safety examination performed for the safety and maintenance of buildings are important tasks to prevent necessary negligent accidents and to take necessary measures such as repair and reinforcement according to the result. However, when performing the full safety inspection and the full safety examination, there are many problems in the inspection using various equipment such as the gradient, level, strength, carbonatization depth, and reinforced state of the main structure. Therefore, this study investigates the problems that appear from the practical point of view during the Full safety inspection and Full safety examination and suggests the improvement method.

Facilities with high risk of a disaster or requiring continuous safety management are designated as class-Ⅲ facility. In order to designate a class-Ⅲ facility, it is evaluated based on the safety status of the facility, the risk to the building users, and the number of years elapsed of the facility, etc. and this shall be referred to the actual condition survey for the designation of a class-Ⅲ facility. In the actual condition survey conducted to designate the safety status is calculated by the checklist based on the evaluation scores consisting of five stages each item, and is evaluated in three stages by 'good', 'careful observation', and 'designated review' through the average of the combined scores. Currently, the actual condition survey being conducted applies only structural stability, and the risk factors such as damage to the finish, the risk of cracking, and the type and weight of major structures are not included in the checklist for the actual condition survey, so even if experts think it is dangerous, scores cannot be reflected. Therefore, this study aims to analyze the problems of checklist of the actual condition survey for the designation of class-Ⅲ facility and to propose an improvement plan for the checklist for the actual condition survey.

A construction project with a total construction cost of over 10 billion KRW should be evaluated whether construction works are appropriately executed. The evaluation is carried out on quality management, process management, construction management, safety management, environmental management. The implementation period is within 60 days after completion of construction of the construction, from the time when the construction rate of the construction work has progressed by more than 90% to the construction cost. However, the participating construction engineers should prepare the evaluation within the period according to the evaluation criteria, but there are difficulties in preparation for the evaluation due to the reasons such as the change of engineers in charge and loss of data. Therefore, this study proposes the procedure of construction evaluation and adjusts timing of construction evaluation.
