Abstract

The modular construction method has been getting more attention followed by global eco-friendly trend as the domestic construction industry has focused more on remodeling and extension work. The modular construction method is an industrialized construction system which is not likely as the existing construction method it manufactures more than 70% modules at the factory then assembling can be completed in a short amount of time on site. The modular construction method has various strengths; shortening of construction period by on-site work decrease, weight pressure reduction by usage of light steel frames and cost saving by repetitive manufacturing. However, it is currently not expanded due to the existing commercialized construction method. Therefore, this research is in order to help the related authorities make decisions to select the construction method and motivate expansion of modular construction method which can be utilized effectively in the extension works. The intention of this research is to stress differentiation from other construction methods in construction period, construction expenses, labor and forces by comparing and analyzing actual cases, to inform competitiveness of modular construction method by concrete effect analysis and to support adoption of the modular construction method into the domestic industry.

세계적 추세인 친환경에 맞춰 국내 건설 산업은 리모델링 및 증축에 관심을 갖게 되면서 모듈러 공법이 대두되고 있다. 모듈러 공법은 기존의 공법과는 달리 공장에서 70%이상을 모듈 형태로 제작하고 현장에서는 단기간 내에 조립만 하여 완성하는 공업화 건축시스템이다. 모듈러 공법은 현장 작업 감소로 인한 공기단축, 경량철골 사용으로 인한 하중 부담 감소, 반복 생산으로 인한 공사비 절감 등 많은 장점을 갖고 있다. 하지만 현재 상용화되고 있는 기존 공법의 진입 장벽이 높아 활성화되지 않고 있는 실정이다. 이에 본 연구는 공법 선정에 영향을 줄 수 있는 관계자의 의사결정에 도움을 주고 모듈러 시장의 활성화를 도모하기 위해 모듈러 공법을 가장 효율적으로 사용할 수 있는 증축 공사에 적용하고자한다. 실제 사례를 비교 분석하여 공기, 공사비, 노무인력 등의 측면에서 타 공법과의 차별성을 강조하고, 구체적인 효과 분석을 통해 모듈러 공법의 경쟁력을 알리고 모듈러 공법의 활발한 국내 도입에 일조하고자 한다.
