Abstract It is one of the most important tasks performed at the beginning stage of construction work, involving the setting out a building according to the design plan on the site. If the setting out a building deviates significantly from the design plan and exceeds legal tolerances, significant problems can arise in the completion and use of the building. Therefore, this study identified the current status of control surveying and verifying the setting out a building on a site, as well as the applicability of 3D laser scanners, which are increasingly useful in the smart construction era, to surveying and verification through case studies. As a result, it was confirmed that both construction managers of construction management companies and construction engineers of construction companies are aware of the importance of setting out a building and primarily attend to and confirm it during surveying and location verification. Additionally, it was found that civil subcontractor engineers, surveying specialists, frame carpenters' foremen, etc. take the lead when carrying out surveys for benchmarks and profiles. Accordingly, construction architectural engineers felt the need for instruments like 3D laser scanners, which could be directly handled, to be introduced not only to verify surveying but also to perform various quality control measures. If used for a variety of activities, it is believed that more precise building construction will be possible, contributing to improving the competitiveness of the construction industry.
