Abstract

The digitalization of tasks for smart construction requires the smooth exchange of digital data among stakeholders to be effective, but there is a lack of digital data standardization and utilization methods. This paper proposes a digital construction information structure to transform information from road construction sites into digital formats. The study targets include significant tasks, such as work planning, scheduling, safety management, and quality control. The key to the construction information structure is separating construction information into objects and activities, defining unit works by combining these two types of information to ensure flexibility in representing and modifying construction information. The objects and activities have their respective hierarchical structures, which are defined flexibly to match the actual content. This structure achieves both efficiency and detail. The pilot structure was applied to highway construction projects and implemented digitally using general formats. This study enables the digitalization of road construction processes that closely resemble reality, accelerating the digital transformation of the civil engineering industry by developing a digital twin of the entire road construction lifecycle.

스마트건설을 위한 업무의 디지털화는 상호 간의 디지털데이터를 원활하게 교류할 수 있어야 효과가 있으나, 디지털데이터의 표준화 및 활용방안이 부족하다. 본 연구는 도로 건설현장의 정보를 효과적으로 디지털로 변환할 수 있는 디지털 건설정보구조를 제안한다. 연구대상은 도로건설업무에서 중요도가 높은 작업계획, 일정관리, 안전관리, 품질관리이다. 건설정보구조의 핵심은 건설정보를 객체와 작업으로 분리하고, 이 두 정보의 결합으로 단위업무를 정의함으로써 건설정보의 표현 및 수정의 유연성을 확보하는 것이다. 객체와 작업은 각자의 계층구조를 가지며, 이 계층구조는 실제 내용에 맞추어 가변형으로 정의하였다. 이는 효율성과 상세성을 동시에 만족하는 구조다. 이 구조를 고속도로 건설공사에 시범적용 하였고, 범용 포맷을 이용해 구조를 디지털로 구현하였다. 본 연구는 현실에 가깝게 도로 건설공사 과정을 디지털화할 수 있으며, 도로건설 전주기의 디지털트윈의 토대가 되어 토목산업의 디지털전환을 가속화 할 것이다.
