The modular building system is a type of prefabricated construction method, and is an industrialized building system that transports, assembles, and completes a three-dimensional module manufactured in a factory to the site. The economics of a modular building system where 50 to 80% of the entire process takes place in a modular factory is dominated by productivity of the factory manufacturing process. Since the building of the module is finished by the combination of unit parts produced by each material, it is necessary to manage the process in each module unit. However, currently marketed process control programs do not reflect the features of these modular methods. In this paper, we introduce Modular Factory Design software(MFD 2019) that can make modular unit production plan which reflects production base(modular factory) and production target(application and number of modular units). In order to verify software compatibility and reliability, two production plans with different production methods were formulated and simulated.

Prefabricated Modular Buildings are increasingly becoming popular in the construction industry as a method to achieve financially economical buildings in a very short construction time. This increasing demand for modular construction has expanded into multi-storey applications where the effect of lateral loads such as seismic loads becomes critical. However, there is a lack of detailed scientific research that has explored the behaviour of modular buildings and their connection systems against seismic loads. This paper will therefore present the nonlinear time history analysis of a multi-storey modular building against several ground motion records. The critical elements that need special attention in designing a modular building in similar seismic conditions is discussed with a deeper explanation of the behaviour of the overall system.

This research was for the investigation and analysis of the illustration of modular construction application which is different use by each school facility since modular construction related examples are rare in domestic situation, and it has a limitation because of its being basic research material for generating the basic form of modular construction. The research results are as followings. First, in case of school facility from illustration investigation results, module measurement of class modulation is as similar as $3m{\times}10m$, but in resident facility the planning of more flexible plane shape can be possible since modules of 6 cases are free and various, and facade form of various types can be appeared by combination of module unit. Second, as a result of the generated characteristics in compared analysis of representative examples, school facilities were highly indicated for movability and duration reduction areas, and the flexibility, economic efficiency, and environment-friendliness was indicated low relatively. Third, the basic planning types of modular construction can be largely divided into layered type, horizontal (straightway) type, and compound type. The layered type has a short traffic line and facility system and is appropriate for the low-rise form unless separate construction method is used since it is susceptible to load. The horizontal type is advantageous for securing an opening since it has wide extent in light but has a long traffic line and facility system. Finally, the compound type can be possible for planning of various forms but needs the combination of various unit modules and traffic line and facility plan for it can be difficult.

The current architectural design of unit modular has been based on 2D of CAD program, so unit modular character which needs unit information management, as a dried-member system, has no effect on design process. The purpose of this study is We have developed a suitable BIM design process, according to various works of construction, then tried to contribute to supply and activation of the urban-life-housing based on unit modular. The BIM modeling process based on unit modular has been in order of unit combination with preparing manual classification, and, it has been constructed, at construction site, from housing foundation to roof finish by Bottom-up method. At a manufacturing factory, it has been produced in order of 1) grouping materials and parts, 2) fabricating unit boxes, and 3) interference examination of unit boxes, and each order has been classified as housing structure, architecture, plumbing process separately. At a construction site, the fabrication has been done in order of, like as a real housing construction scenario, 1) RC foundation work 2) unit module job-site-fabrication work, 3) roof truss work, 4) plumbing and HVAC work, and 5) housing interior finish work. After modeling process, the interference examination on each work of construction has finally completed modeling. The Unit modular utilizing BIM modeling can make easy housing maintenance through systematic control with preparing manual of unit module information, and securing accurate and speedy construction information. And it will promote design credibility and create maximum effect of unit modular construction method, such as construction period reduction and upgrade of construction quality, etc., through the computer simulation as real as construction environment in cyber space, and with the interfering examination.

Existing modular research has been mainly focused on S (shelter structure) and I (infill interior finishing material), and considerable research has been conducted, and the results are being proposed. However, in the case of the rest (exterior materials and windows, etc.), existing construction methods and materials are borrowed, and supporting hardware members and insulation materials are constructed on site, which acts as a factor hindering overall shortening of the construction period. That is, since the advantages and characteristics of modularity cannot be utilized in the absence of modular cladding, manufacturing of cladding is required. Therefore, it is necessary to develop a cladding system that can drastically reduce the construction period in factories while considering the structural characteristics of PC modulars.

우리나라의 모듈러 공법은 컨테이너하우스나 경량스틸 하우스로만 인식되고 있어, 수요창출에 상당한 어려움이 있다. 실제로 모듈러빌딩 활성화에 가장 큰 장애요인은 안정된 수요에 근거한 지속적인 공장 생산이 거의 어렵다는 것이다. 본 연구는 모듈러 공법의 대표적인 미국과 영국의 모듈러 기업의 사례 조사를 통하여, 건물 유형별로 모듈러 공법의 성공요인을 우선적으로 도출하였다. 10개의 건물유형과 9개의 성공요인으로 정리하여 조사한 결과, 주거시설은 공기단축, 설계성능, 경제성 순으로 중요도가 높았으며, 교육시설의 경우에는 공기단축, 친환경성, 경제성, 융통성 순으로 나타났다. 병원시설은 공기단축, 융통성, 경제성, 친환경성이 주요 성공요인으로 나타났으며, 이러한 성공요인들이 확보될 경우 우리나라에서도 모듈러 공법의 성공 가능성은 충분히 있다고 생각된다. 주거시설의 겨우 표준화된 모듈 설계안의 반복적인 활용을 통하여, 성공요인을 확보할 수 있으며, 교육시설의 경우, 단모듈-장모듈의 타입화된 모듈의 설계안을, 병원시설의 경우 증축기술의 개발을 통한 성공요인이 확보할 수 있을 것이다. 모듈러공법의 수요창출 방안을 적용할 수 있는 잠재적인 시장의 규모는 주거시설의 경우, 연간 약 12,000호 규모의 시장이 형성 가능하며 기숙사의 경우, 2012년 1,515억 원 정도의 시장규모를 볼 때, 모듈러 공법의 시장 확보가 충분히 가능하다. 교육시설의 경우, 주거시설보다 평면의 반복정도가 더 높기 때문에 충분한 시장형성이 가능하다. 병원시설의 증축시장은 2012년 1,045억 원 정도의 규모로 모듈러 공법이 적용된 사례가 전무하지만 앞으로의 진출 가능성은 충분하다. 본 연구에서 제안한 건물 유형별 수요창출 방안은 발주자가 공법을 선정할 때, 건물 유형에 맞는 전략을 수립하는 데에 조언으로서 활용할 수 있으며, 잠재적 시장을 파악한 결과 충분한 시장 규모를 확보할 수 있을 것이라고 기대할 수 있다. 또한 모듈러 설계 및 제조업체는 본 연구에서 제안한 방안을 사업전략으로 활용함으로써 전략적으로 건물 유형에 맞는 사업 방향을 설정하여 지속적인 수요창출을 기대할 수 있을 것이라고 생각한다.
