Abstract

The purpose of this study is to analyze the effects of smart construction equipment applied at the construction site of the first smart city in the Korea and derive an application strategy for the utilization of smart construction equipment. To achieve this, aythors examined the practical effects and issues of safety systems and construction systems utilizing machine guidance (MG) technology, which is a representative smart construction equipment used in civil engineering construction sites. Both the MG safety system and MG construction system were found to be sufficiently effective in improving construction productivity. However, there are challenges that need to be addressed, such as the approval process for work results using MG systems, system changes due to frequent replacement of on-site equipment, and usability improvements for elderly on-site workers. The study presented some solutions that have been implemented on-site to address these issues. The utilization effects and issues presented in the study were analyzed through direct feedback from workers and managers who have utilized the MG technology on-site for a considerable period of time. These results can be used as preliminary data for the similar construction projects, considering the limited availability of empirical analysis data for equipment automation.

본 연구는 국내 최초 스마트시티로 지정된 건설 현장에 적용된 스마트건설장비의 효과를 분석하여 향후 스마트건설장비의 발전 및 활성화 방안을 도출하는데 목적이 있다. 이를 위해 토목공사 현장에 적용되는 대표적 스마트건설장비인 머신가이던스(Machine Guidance; MG)기술에 의한 안전시스템과 시공시스템의 실제적 활용 효과와 문제점을 분석한 후에 개선방안을 제시하였다. MG안전시스템과 MG시공시스템 모두 결과적으로 시공성 개선에 충분히 활용성이 있음을 파악하였고, MG시스템에 의한 작업결과의 승인문제와 잦은 현장 장비교체에 의한 시스템 변경문제, 고령의 현장 근로자의 사용성 개선문제 등이 속히 해소해야 할 과제로 분석되었으며, 연구에서는 이러한 문제에 대해 현장에서 해결한 일부 방안을 제시하였다. 연구에서 제시한 활용효과와 문제점 등은 머신가이던스기술을 현장에 상당기간 실제로 적용한 후에 직접 활용한 근로자와 관리자 등을 통하여 분석하였으므로, 장비자동화를 위한 실증적 분석 자료가 많지 않은 점에서 향후 유사 현장에 적용하기 위한 선행자료로 활용성을 갖을 수 있다.
