Abstract

건설 산업 생애주기 전반에 걸친 정보를 BIM을 활용하여 관리할 수 있게 되었다. 그 중에서도 BIM기반 물량산출은 공사비와 직결되는 중요한 관리 요소로서 사업 타당성 및 경제성 분석을 위한 필수적인 관리 요소 중에 하나이다. 또한, BIM기반 물량산출 Data는 작업자마다 물량산출 결과가 상이하게 나타날 수 있으므로 BIM모델 구축에 대한 정확한 기준이 필요하다. 이러한 BIM기반 물량 산출은 정보의 신뢰성과 정확도 측면에서 매우 중요하다. 따라서 본 연구에서는 BIM기반 물량산출 결과의 정확도 및 신뢰성을 판단하고, BIM 모델링의 현실적이고 바람직한 방법을 제시하고자 단위세대 내부 마감재를 개별부재와 복합부재로 모델링하여 산출되는 BIM기반 물량산출 결과를 정량적으로 비교 검증하였다. 연구의 결과, 정확한 BIM기반 물량산출을 위해서는 다양한 마감재를 개별부재로 모델링하는 것이 바람직하지만, 작업의 생산성 측면에서 보다 현실적인 BIM기반 물량산출을 위해서는 개별부재와 복합부재를 병용하여 모델링 작업을 실시하는 것이 현실적인 BIM 모델링 방법임이 검증되었다. Construction industry throughout the construction projects life cycle using BIM is able to manage information. Among them, BIM-based quantity take-off is directly connected to the data of the construction business as an important management element that is essential for one of the management factors of feasibility study and economic analysis. In addition, the result of BIM-based quantity take-off can be varied depending on modeler, so the exact guideline for BIM modeling is necessary. The BIM-based quantity take-off in terms of reliability and accuracy of the information is very important. Therefore, this study verified the BIM modeling of the apartment interior materials using both separate object and composite object was validated the quantitative comparison of the difference in BIM-based quantity take-off for accuracy & reliability judgment of BIM-based quantity take-off and realistic & desirable suggestion of BIM modeling way. As the result of this study, it is preferable to model various interior materials to use separate object for the purpose of correct BIM-based quantity take-off, but the realistic way of the BIM modeling using both separate object and composite object jointly was verified in order to judge BIM-based quantity take-off in terms of work productivity.
