Abstract

Costs and expenses are intertwined and incurred throughout an entire construction project, even from the pre-construction phase, and each phase has a different impact on the life cycle cost (LCC). However, the cost breakdown structure (CBS) is different in each phase of a building construction project, which makes it hard to reasonably calculate construction cost. For this reason, the boundary conditions were analyzed in this study based on the life cycle cost break structure (LCCBS). In addition, breakdown factors were analyzed based on the boundary conditions to derive a linkage method. The validity of the linkage method was verified through application to actual construction projects. Through the analysis, it was found that the problem of items being left out was reduced by more than 97.2 percent, and the work was done an average of 6 hours faster compared to the conventional method. It is expected that by applying the new LCC system, LCC will be both reduced and calculated in a more efficient manner.

건축물의 생애주기비용은 시행과정 전 단계에서 상호 연관되어 비용이 발생하며 각 단계마다 서로 간에 영향력이 존재한다. 하지만 건축 프로젝트의 각 단계별 CBS가 서로 상이하여 합리적인 공사비를 산정하는데 문제점이 발생한다. 따라서 본 연구에서는 기존에 연구되었던 LCCBS를 바탕으로 건축 프로젝트 각 단계 간에 경계조건을 분석하였다. 또한 분석된 경계조건을 바탕으로 분절요인을 분석하고 이에 따른 연계방안을 모색하였다. 연계방안의 유효성 검증을 위해 실제 건축프로젝트를 바탕으로 사례적용을 실시하였다. 분석결과 누락되는 항목이 97.2%이상을 개선하였고 평균 6시간 빠르게 업무를 수행할 수 있음을 확인할 수 있었다. 향후, LCC 시스템에 적용함으로써 LCC의 효율적인 산정 및 LCC 절감을 계획할 수 있을 것으로 사료다.
