The problems of lack of skilled worker and poor productivity at the construction site continue to be raised, and the introduction of construction automation as one of the solutions to this has been considered. The development of various types of equipment and systems has been carried out, especially for earthwork operations with multiple construction equipment. However, the level of commercialization of developed equipment or systems is very limited. Although the single-product type of earthwork equipment has been applied to the site, the integrated type of earthwork system is still in the field testing stage. Considering these constraints, the limited budget and research period, a strategy is needed to identify which technology areas and core technologies should be developed first. In this study, the technology areas and detailed core technologies that are essential for the development of earthwork systems at the level of commercialization are set and the priority of development is determined. In addition, the earthwork system that has been developed so far is analyzed and the detailed development direction is presented based on it. The findings can be used for a decision making to set the priority for core technologies that should be developed first in the limited budget and period.
건설현장에 숙련공 부족문제와 생산성 저하 문제가 지속적으로 제기되고 있으며, 이것에 대한 해결책의 하나로 건설자동화 기술도입이 검토되어 왔다. 이러한 배경에서 다양한 형태의 장비 및 시스템 개발이 이루어져 왔고, 특히 다수 및 다종의 건설장비가 투입되는 토공작업을 위한 개발이 많이 수행되었다. 하지만 개발된 장비나 시스템이 상용화 수준에 도달한 것은 매우 제한적이다. 그나마 단품 형태로 개발된 토공장비의 경우에는 현장에서 적용되고 있는 사례를 볼 수 있으나, 시스템 형태로 개발된 것은 각종 기능이 유기적으로 통합된 것이 아니라서 현장 테스트 단계에 머무르고 있다. 이러한 제약사항을 극복하고 제한된 예산과 연구기간을 고려할 때 어떤 기술분야의 어떤 요소기술들을 우선적으로 개발을 해야 하는지 전략이 필요하다. 본 연구에서는 상용화 수준의 토공시스템 개발을 위하여 필수적인 요소기술 분야와 세부 요소기술들을 설정하고 개발 우선순위를 결정하였다. 아울러 현재까지 개발이 완료된 토공시스템을 분석하고 이것에 근거하여 세부적인 개발방향을 제시하였다. 연구결과는 제한된 예산과 기간동안에 우선적으로 개발해야 할 기술을 설정하는데 사용될 수 있을 것이다.
