Abstract
When the public surveying system was introduced in 1961, large scale surveying performances, such as infrastructure construction work, were dominant. However, due to changes in the environment, most of the current surveying performances focused on small scale underground facilities. The method of surveying underground facilities is as follows: "method of measurement before refilling after burying the pipeline" and "method of using exploration after refilling." There are advantages and disadvantages to each method. It became difficult to obtain the accuracy of the location of the underground facilities due to the fact that there were sections of the pipeline that had not been observed through exploration. Therefore, the 2017 performance evaluation regulations were revised. The revision included the addition of the "Underground Facilities Creation Period," a system that allows for surveys to be evaluated based on actual measurements. However, in this particular field, concerns about the advantages of exploration and the purpose of this study was to investigate the background and purpose of the limitations of the survey have been continuously raised. The purpose of this study was to investigate the background and purpose of the public surveying system and to identify the proportion of underground facilities surveying in comparison to public surveying. This study conducted surveys on the implementers of public surveying and those who did the actual surveying. The researcher has summarized the improvements that incorporate the analysis results and the field comments in the revised performance evaluation regulations in 2017.
