Abstract

Construction industry pays attention to modular construction recently which based on factory production not on labor intensive site production. Since modular construction has high time shortening effect and easiness of demolition and recycling, it has been applied to the temporary residential building. Domestic modular construction market are not activated yet, however, due to the high initial cost to realize modular construction. This study proposes demand-sensitized movable modular building in order to reduce the financial burden. The study compares between RC method building and Modular building which moves building when the demand falls off from Life-Cycle Cost's viewpoint. As a result of the economical evaluation, RC method achieved profits faster than Modular model, but Modular model's gross earnings during the life-cycle are much bigger than RC method. In other words, the result means that the market-sensitized movement of the modular building would be an economci choice in Life-Cycle Costing aspect.

최근 건설프로젝트는 기존의 노동집약적 현장생산 방식이 아닌, 공장 생산 기반의 현장 조립 방식인 모듈러 건축물에 주목하고 있다. 모듈러 건축 공법은 기존 방식에 비해 공기 단축효과가 높고, 해체 및 재사용이 용이해 임시 주거시설을 중심으로 적용되고 있다. 그러나 모듈러 공법 실현을 위한 초기 투자비용에 대한 부담으로 인해 국내의 모듈러 건축시장은 아직 활성화되지 못하고 있다. 이에 본 연구에서는 모듈러 건축물이 가지고 있는 경제적 부담에 대한 대안으로서 시장의 수요에 따라 이동 가능한 모듈러 건축 방식에 대하여, 기존의 건축 방식과의 생애주기비용 비교를 통해 경제적 효과를 분석하고자 한다. 본 연구에서 분석의 대상으로 삼은 RC 공법과 모듈러 공법의 이동형 모델의 경제성 평가 결과, 단기적인 측면에서는 RC공법이 빠른 수익률을 달성하였지만 건물의 전 생애주기 측면에서는 이동 가능한 모듈러 건축 방식의 경제성이 보다 큰 것으로 나타났다.
