Abstract

To control manage environmental load during construction work, it is required to ascertain an accurate quantity for materials those are using during the construction. In construction industrial nowadays, especially on design part, there are lots of mistakes occurred on quantity take-off between plan documents and actual work. That mistakes are caused by omission of design items, overcount because of interference each materials or simple calculate error. Besides, in case of a construction project, engineers are impossible to design perfectly due to a lot of invalid variable in a construction site. Thus, design errors and changes occur frequently in the process of construction work or design due to such unclear elements. And in case of LCA assessment based on 2D design, there is difficult for an engineer who is in charge to calculate the volume of materials manually using drawings and relevant specifications. This study is aimed for examining and verifying a high reliable method of evaluating environmental load which is useful in construction process through comparing LCA analysis. In addition, this study provides the method of calculating the volume of materials and LCA assessment in working on the basis of 2D design, using the specifications which is used for LCA evaluation, and possibility of utilizing the LCA assessment by introducing BIM design technic to improve the former problem through comparing and analyzing the previous method with 3D-based evaluation process.

건설공사시 발생하는 환경부하 관리를 위해서는 시공시 실제 투입되는 물량을 면밀히 파악할 필요가 있다. 현재 건설공사에서는 2D도면을 활용한 설계의 경우에는 실제 설계 도서간 물량산출 값의 오차, 설계항목의 누락이 발생하고 있으며 건설 공사의 경우 불확실한 요소들로 인하여 시공 중에도 빈번히 설계변경 및 오류가 발생하고 있다. 또한 2D 설계를 바탕으로 하는 LCA평가의 경우 도면, 내역서 등을 이용하여 작업자가 수기로 작업공종에 투입되는 자재를 산출해야하는 어려움이 있다. 본 연구에서는 2D 설계를 바탕으로한 물량산출과 BIM기반의 물량산출을 바탕으로 LCA 분석을 비교하여 시공과정에서 활용 할 수 있는 신뢰도 높은 환경부하평가 방법을 검증하고자 한다. 또한 설계도서를 활용한 내역기반의 2D설계의 물량산출 및 LCA 평가 방법을 제시하고, 3D 기반의 평가 프로세스를 비교 분석하여 BIM 설계기법 도입에 따른 LCA 평가 활용 가능성을 제시하고자 한다.
