Abstract

This paper provides theoretical deformation of lean concept and its application for usage of building information modeling (BIM) process. Recently, much research is focused on application of lean concept for more efficient usage of BIM. The lean theory and its basic function and feature is based on manufacturing industry. The manufacturing process can be improved by process re-engineering steps of lean concept which consist of the steps of value, value stream, flow, pull, perfection. However manufacturing process and construction process has different characteristics. Due to the differences, five steps of the traditional lean's process re-engineering can't be directly applied to the BIM based engineering process. In order to solve this problem, we conduct analysis on the characteristics of the manufacturing process and BIM based engineering. We propose modified and expanded concept of lean for process re-engineering and the modified theory was applied to the mechanical, electrical and plumbing (MEP) coordination process. Through the proposed 8 steps of methodology, 2D based process was changed to integrated and using BIM based MEP coordination process. In addition, the results showed the potentiality of cost reduction and process improvement. The results of this study can be a foundation for the theoretical combination of lean and a variety part of construction engineering process.

이 논문은 프로세스 재설계 관점에서의 린 (lean) 개념의 이론적 변형과 BIM 프로세스 개선 사례를 제시한다. 최근에는 BIM을보다 효율적으로 사용하기위해 린 개념을 접목하는 연구들이 증가하고 있다. 린 이론과 성격과 기능은 제조업을 기반으로 하며 제조업에서의 프로세스는 린 개념의 프로세스 재설계 과정에 의해서 변형된 하나 프로세스로 개선된다. 하지만 제조 공정과 건설 공정은 다른 특성을 가지고 있다. 두 산업의 서로 다른 차이점으로 인해 전통적인 린의 프로세스 재설계 기능의 5 단계에는 이론적으로 BIM 프로세스에 그대로 적용하기에는 어려운 단계들이 포함되어 있다. 본 연구는 부분적으로 적용되는 린 개념의 접목을 해결하기 위해 제조 공정 및 BIM 프로세스의 특징을 분석했다. 이를 통해 이론적으로 린의 프로세스 재설계 단계를 수정하고 확장했다. 변형된 프로세스 재설계 단계는 설비전기 설계조율 프로세스에 적용했다. 본 연구에서 제안한 8단계의 프로세스 재설계 단계를 통해 일체화된 BIM 프로세스로 변형할 수 있었다. 또한 사례연구 결과는 공정 단계의 감소 및 비용절감의 가능성을 나타냈다. 본 연구의 결과는 BIM 프로세스 뿐만 아니라 다양한 프로세스에 접목될 수 있는 린 개념의 이론적 기초가 될 수 있다.
