Abstract

In this paper, a retaining wall system, developed using building Information modeling (BIM), is presented. Based on the information from a literature review, elementary technologies for the system were defined and developed. First, for the elementary technology, BIM libraries were constructed using standards and previous study results to achieve versatility and reusability. Second, methods for determining the quantity take-off (QTO) of a retaining wall were reviewed for an earth-work calculating system. Additionally, inverse distance weighting interpolation was used to generate topography. Finally, four formulas for calculating the QTO were proposed and devised for each element. After its development, the BIM system was analyzed and verified through comparison with a two-dimensional drawing-based QTO. The proposed system is deemed to be practical for determining the QTO of retaining walls and earth works. The contributions and limitations of the research are discussed in this paper.

본 논문에서는 BIM을 활용한 흙막이 시스템을 개발하고 소개한다. 선행 연구 분석을 통해서 흙막이 BIM 시스템을 이루는 기술들에 대한 조사를 바탕으로 요소 기술들을 개발하였다. 첫 번째 요소 기술로, 선행 연구 및 표준 등을 활용해 BIM라이브러리를 구축하여 범용성과 재사용성을 확보하였다. 두 번째로, 토공 2D 기반의 토공 물량 산출법들을 분석하고 흙막이 BIM 시스템으로 활용하되 추가로 IDW 보간법을 활용하여 지형 생성 및 토공량 산출 시스템을 구축하였다. 세 번째로, 물량 산출을 위한 4가지 수식을 제안하여 객체마다 각각 다르게 물량 산출법을 적용하여 개발하였다. 이후, 시스템에서 산출되는 물량산출서와 2D 기반 물량산출서와의 비교와 검증을 통해서 시스템이 앞으로 나아가야할 방향과 한계에 대해 알아보았다.
