The modular construction is as yet early stage of market in Korea. So It is have difficulty of market demand forecast of the modular building. Therefore, this study was done analysis for market trends of the modular building using ARIMA(Auto Regressive Integrated Moving Average) model by time series data.

Modular construction technique is an adaptation of factory-based mass production concept in ordinary manufacturing industries to construction industry and it assumes that panels, units, etc. are fabricated in factories and assembled in construction sites. Given its structural limitations, modular construction technique is primarily used in low-story buildings whose maximum height is usually five stories, but researchers are actively studying possible adaptation of modular construction technique to high-rise building designs these days as in the case of infill-type modular construction design. Infill-type modular construction technique, most frequently used in high-rise building construction projects, completes frame construction first in reinforced concrete structures and fills unit modules in such structures. However, infill-type modular construction technique leads to longer construction schedule accompanying increase in construction cost, cost overrun due to additional of temporary work, and possible damage to units in the wake of facility construction. Accordingly, this study is performed as a basic study for the development of bottom-up infill-type modular construction technique intended to construct structural frames and fill in units sequentially in a bid to address such drawbacks of current infill-type modular construction technique.

Modular construction is a process in which a building is produced off-site in module boxes using standard materials. Since the introduction of prefabrication in building construction, Modular Coordination (MC) has become an essential design tool in building design and construction. However, in Korea, the design standardization has not been adequately applied to modular construction. This study intends to analyze the current status of modular construction in Korea and explore the applicability of MC design in the construction industry. The analysis of the current status of MC design within Korean four major modular construction companies indicates that an incremental dimension is not properly used in horizontal planning modules, which results in a problem of increasing construction cost by high material loss rate. But, in vertical planning modules, a incremental dimension of 100 mm (1 M) is found to be used although the structural system varies among manufacturers, which demonstrates the potential for an open system to be well applied in modular construction, despite different structural systems.

모듈러 공법은 내장재와 기계·전기 설비 등이 시공된 구조체를 제작 공장에서 건설 현장으로 운반하여 설치 및 시공하는 공법이다. 모듈러 공법은 특히 주택과 같은 소규모의 비교적 구조가 간단한 건축물을 대상으로 활발하게 적용되고 있는 추세이다. 국내건설 산업에 모듈러 주택의 도입된 기간이 길지 않은 만큼 아직 모듈러 주택의 환경적 특성에 대한 연구가 부족한 실정이다. 따라서 본 연구의 목적은 모듈러 주택의 단열성능을 적외선 이미지 분석과, Air-Surface Thermal Ratio 방법, 실내외 온도차비를 활용하여 실증적으로 분석하는 것이다. 이를 위해 실제 서울시에 위치한 준공 후 2년이 경과된 모듈러 주택과 RC 주택을 비교하여 단열성능 분석하였다.

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.

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.

모듈러 건축은 시공 기간의 단축, 건축비용 절감 등의 여러 가지 장점에도 불구하고 국내 건설시장에서 좀처럼 탄력을 받지 못하고 있다. 이러한 원인에는 모듈러 내화 기술 적용의 한계도 있으나 무엇보다 내화구조 제도에 대한 접근성이 쉽지 않은 것이 주요 요인으로 간주되고 있다. 따라서 모듈러 건축 활성화를 위해 주요 저해요인인 내화구조 제도 현황과 문제점에 대해 고찰하였으며, 내화구조 제도적 개선 및 연구개발 방향에 대해 제시하고자 한다.

With the progress of national policy researches on the modular construction, many studies have been conducted regarding the standardization of interior building materials. However, studies on the standardization of exterior building materials are still insufficient, and there are no dedicated exterior materials for modular construction. In this regard, this study investigated the necessary of standardization through the analysis on 7 kinds of exterior materials used in general buildings and exterior building materials applied to modular apartment houses in order to establish design criteria for the standardization of dedicated modular exterior materials. Based on the analysis results, assembly reference plane in conjunction with inside dimensions was set, and panelizing standardized in five parts was proposed to solve the problem of low exterior material standardization rate. It also proposed elastic gasket and steel bracket details that can compensate for the fabrication errors of unit boxes and construction errors in stacking.

Recent research has been ongoing for modular buildings in the country, and interest increases. However, in accordance with legal restrictions in the country with regard to Project Delivery system of Modular Building, the activation of modular buildings industry is obstructed. In Korea, in accordance with national contract law, the construction contract is apply to the project delivery system of modular buildings, and in accordance with Framework Act on the Construction Industry, The project delivery system of modular buildings has to be a separate order. The definition of separate order in contract as defined in the law is that the electric work and Communication work and digestion facility work has to be separate each contract in order to be ensured professionalism. In accordance with law, the project delivery system of modular buildings is that the contract for construction is concluded with the Owner and the Construction Contractor and the contract for goods is concluded with the construction Contractor and modular manufacturer. Due to these project delivery system, the domestic factory production rate when making a modular unit is significantly reduced compared to the rate of factory production abroad and the domestic factory production rate is estimated to 10-20%. Due to the factory production rate is also low, despite what can be done at the factory the workload in construction field increases. According to the workload in field increases, the effect of the schedule reduction can be reduced. It resolved to form a consortium with a modular manufacturer and construction companies or the contract is concluded with Owner, modular manufacturer and construction companies in each. In this paper, we propose a specific project delivery system for modular building to solve the problem of the low factory production rate and the problem of schedule reduction. Through this paper, due to the variety of project delivery system on modular buildings is expected to contribute to the activation of modular buildings.
