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.

A modular house is a house that is assembled on-site from modularized units. As such units are manufactured in a factory, the construction period is reduced, resources are recycled, and quality is improved. However, the construction technique applied to conventional modular houses has not overcome certain structural restrictions, as it is currently used to build houses less than 4 stories in height, which means that it lacks economic feasibility. For this reason, this research aims to develop a scenario of a construction method for Korean modular housing that can be applied to urban-type housing higher than 12 stories. This research is expected to provide fundamental data necessary for the future development of a construction method for Korean modular housing.

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.

This paper describes the classification problems of the unit modular housing through reviewing design drawings. Modular construction is a new industrialized homebuilding technology that uses large, factory produced modules. In general, more than 70% of construction processes in unit modular construction method are produced in factory after that the modular, which is completed is lifted on site and assembled. This research considers categorization in which the design drawing of the unit module housing can have problems. There are 17 types of construction method and 14 types of design approach as a result of the classification.

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.

Modular construction is a construction method whereby prefabricated volumetric units are produced in a factory and are installed on site to form a building block. The construction productivity can be substantially improved by the manufacturing and assembly of standardized modular units. 3D printing is a computer-controlled fabrication method first adopted in the manufacturing industry and was utilized for the automated construction of small-scale houses in recent years. Implementing 3D printing in the fabrication of modular units brings huge benefits to modular construction, including increased customization, lower material waste, and reduced labor work. Such implementation also benefits the large-scale and wider adoption of 3D printing in engineering practice. However, a critical issue for 3D printed modules is the loading capacity, particularly in response to horizontal forces like wind load, which requires a deeper understanding of the building structure behavior and the design of load-bearing modules. Therefore, this paper presents the state-of-the-art literature concerning recent achievement in 3D printing for buildings, followed by discussion on the opportunities and challenges for examining 3D printing in modular construction. Promising 3D printing techniques are critically reviewed and discussed with regard to their advantages and limitations in construction. The appropriate structural form needs to be determined at the design stage, taking into consideration the overall building structural behavior, site environmental conditions (e.g., wind), and load-carrying capacity of the 3D printed modules. Detailed finite element modelling of the entire modular buildings needs to be conducted to verify the structural performance, considering the code-stipulated lateral drift, strength criteria, and other design requirements. Moreover, integration of building information modelling (BIM) method is beneficial for generating the material and geometric details of the 3D printed modules, which can then be utilized for the fabrication.

In modular construction, safety management is required to prevent the occurrence of risk factors such as lifting work and high place work due to the characteristics of the construction method. Therefore, this study is a basic study for safety management of modular construction, and the purpose of this study is to compare and analyze the classification system of modular construction derived by analyzing the construction process of the existing case. Based on the results of this study, the safety management classification system will be used in future research to derive safety management factors in modular construction.

In modular construction, it is insufficient for safety management of workers, and workers are still exposed to the risk of accidents due to work at high places for lifting and assembly work in modular construction sites. Therefore, it is necessary when preventive safety management through risk management of workers on modular construction sites. This study is a basic study for the risk assessment(checklist) of modular construction, and the purpose of this study is to analyze the risk factors of the module lifting work at the modular construction site. It is intended to identify the hazard risk factors and improvement measures of the existing lifting operation, by analyzing the case of the risk assessment of the existing RC method, and to identify the risk factors for each work process when lifting the module. In the future, the results of this study are expected to be utilized in the development of checklists for risk assessment as safety management plan for modular construction sites.

OSC(Off-Site Construction) is regarded as a faster and more economical method in the construction industry, and the attention towards the OSC is growing. In the modular construction process, which is one type of OSC, accurate identification of a module is essential. Because the installation position and the MEP(Mechanical, Electrical, and Plumbing) composition are distinct between modules, a defect in the finishing or junction area is likely to happen during the construction process. This study suggested the modular construction process by applying a beacon receiver using BLE(Bluetooth Low Energy) technology on each module. Construction quality management would be improved using the location and assembly data, particularly for a different module in modular construction.

Modular construction is a cost-effective and time-saving method of building that involves prefabricating modules in a factory and assembling them on-site. However, effective management factors must be considered at each stage of the process to ensure quality and stability. This study analyzes these management factors and proposes systematic ways to manage them, including construction planning, data management, and quality assurance. Proper management can improve construction quality, shorten construction time, and reduce costs. These stage-specific management factors are crucial for the success of modular construction projects, and further research and efforts are needed to promote its widespread use in the construction market.
