Abstract

3D printing is making a huge difference to existing industries and is beginning to be applied in the field of construction. 3D printing construction differs from existing construction techniques. Therefore, new construction processes need to be developed. In particular, the accurate construction duration is linked directly to a successful project. A method for estimating the construction duration for 3D printing construction is necessary. In this study, a 3D printing construction process and duration estimation method were derived to prepare for the future introduction of 3D printing in construction. The scope of the study was assumed to be 3D printing equipment capable of pouring concrete, and limited to a frame structure construction. The developed construction period estimation method was applied to the virtual test model. As a result of applying the test model, the construction duration was shortened by approximately 50% compared to the existing construction technique. The method of estimating the construction period developed in this study can be applied to 3D printing constructions in the future and help establish a business plan.

3D 프린팅은 기존 산업에 큰 변화를 일으키고 있으며 건설 분야에도 적용되기 시작하고 있다. 3D 프린팅 건설은 기존 공사 기법과는 차이가 있으므로 새로운 공사 프로세스 개발이 필요하다. 특히 정확한 공사기간 산정은 프로젝트의 성공적인 수행과 직결되어 있으므로 3D 프린팅 건설에 대한 공사기간 산정 기법 개발이 필요하다. 본 연구에서는 향후 3D 프린팅이 건설에 도입되는 것을 대비하기 위해 3D 프린팅 건설 프로세스 및 공사기간 산정 방식을 도출한다. 연구의 대상은 콘크리트 타설이 가능한 3D 프린팅 장비로 가정하였으며, 골조공사로 한정 한다. 도출된 프로세스 별로 유사한 건축 표준 품셈을 참고하여 3D 프린팅 공사기간을 산정한다. 개발된 공사 기간 산정 방식은 가상의 테스트 모델에 적용되었다. 테스트 모델 적용 결과 기존 공사 기법 대비 약 절반 가량 공사 기간이 단축되는 것을 알 수 있다. 본 연구에서 개발된 공사기간 산정 방식은 향후 3D 프린팅 건설에 적용되어 사업 계획 수립에 도움이 될 수 있다.
