Abstract

3D printing technology is attracting increasing attention as a key technology of the fourth industrial revolution that can change the production paradigm of existing industries. The introduction of construction 3D printing technology has been slower than other industries because of the characteristics of the construction field. On the other hand construction automation using 3D printing is required to reduce the production population, as well as improve productivity and safety. In this study, a construction 3D printing work breakdown structure and link method to a standard estimation system were developed as a preliminary preparation for introducing 3D printing to construction. Based on expert consultation on construction and 3D printing, a hypothetical scenario was developed based on existing construction 3D printing technology. According to the scenario, 16 kinds of works required for 3D printing construction work were derived. The existing work breakdown structure and standard estimation system were analyzed, and the 3D printing work was linked. 3D printing works that were the same as the existing breakdown structure were found, and non-existent works were added to the similar breakdown structure. These results are expected to be helpful for future 3D printing construction management and cost estimation. The actual standard estimation system through 3D printing work will need to be calculated.

3D 프린팅 기술은 기존 산업계의 생산 패러다임을 변화할 수 있는 4차 산업혁명의 주요기술로 큰 관심을 받고 있다. 건설분야의 특성으로 인해 3D 프린팅의 기술 도입이 타 산업분야에 비해 느리지만, 향후 생산인구의 감소와 생산성 및 안전도 향상 등을 위해 3D 프린팅을 활용한 건설 자동화가 필요하다. 본 연구에서는 3D 프린팅을 건설에 도입하기 위한 사전준비로서 건설 3D 프린팅 공종분류체계와 기존 표준품셈체계와의 연계방안을 제시 한다. 이를 위해 건설 및 3D 프린팅 관련 전문가 자문을 바탕으로 기존 건설 3D 프린팅 기술을 바탕으로 가상의 시나리오를 작성하였다. 시나리오에 따라 3D 프린팅 공사 수행에 필요한 16개의 공종을 도출하였다. 기존 공종분류체계와 표준품셈을 분석하고 도출된 3D 프린팅 공종을 연계하였다. 기존 분류체계와 동일한 3D 프린팅 공종도 있었으며 기존에 존재하지 않는 공종은 유사한 분류체계 하위에 추가하는 등 4가지 타입으로 구분하였다. 본 연구의 결과는 향후 3D 프린팅 공사관리 및 원가산정에 도움이 될 수 있을 것으로 기대된다. 향후 3D 프린팅 공사 수행을 통해 실질적인 품셈 산출이 필요하다.
