The unit modular method is one in which unit modules are prefabricated at a factory and then constructed at a construction site. That is why an important process, transporting unit module, is added in this method. The purpose of this study is to analyse the load for transporting unit module. The results of the analysis of the driving experimental runs revealed that a maximum load of 15 kN was applied on adapter block type A and a maximum load of 25 kN on adapter block type B. These loads were recorded at the points in the road test when the low-bed trailer was driving through unstable sections of the test such as stopping, restarting, passing over a speed bump or taking a left turn at speed.

This study was conducted to present useful information on the utilization and productivity analysis of laminated modular multi-family housing. To this end, the process of site installation was investigated and analyzed through a prior study, and the monitoring survey was conducted through the site installation case of an stacked multi-family housing. Based on the above, the results of productivity analysis using the web-cyclone technique were also presented. However, the site installation process has limitations on generalisation because the process is not the same for each construction company, and also limits that require verification through application in the actual site of the web-cyclone model presented in this study.

The aim of this study is to evaluate the productivity of multilayered modular housing units during the prefabrication phase. Additionally, it shows the results of productivity analysis conducted using the Web Cyclone technique. Initially, an review of literature and prior studies helped outline the comprehensive manufacturing process of laminated modular apartments, examining the range of minimum, average, and maximum work durations along with workforce size. Subsequently, the productivity of the multilayered apartments' prefabrication was assessed using the Web Cyclone technique, focusing on the workflow, duration, and personnel involved. This analysis also included a comparison of productivity against the initial plan based on the outcomes of a sensitivity analysis.

This study attempted to explore the MC design methods of modular construction using discontinuous double module grids and further, the design methods of walls. Modular construction is generally characterized with multiple units called modules with a module dimension of 3M(300mm) appearing in the form of double grids. The discontinuous double grids including correction values and gap values occurs inevitably in the modular construction where units are joined horizontally. Therefore, it is desirable to carry out the MC design taking into account these discontinuous double grids. In this study, the MC design was applied to the plane of wooden houses in modular construction, going through a process of setting the size of pillars and inside dimensions, of determining the dimension of discontinuous double grids that occur during the assembly of units, and of setting the dimension of outer walls in conjunction with the derived dimensions. The dimension of outer walls was applied differently depending on the range of regional use by analyzing the energy performance with the materials used. Consequently, the materials and components of factory-produced buildings can be used directly without processing, and the suitability of the outer wall design can be pre-determined by previewing the calculation of the cross-sectional configuration and heat transmission coefficients of outer walls in modular construction, allowing to be used as a decision-making tool of design.

In foreign countries, the use of containers has already been stabilized with their advantages utilized in various forms. Containers are also utilized in Korea as various forms of architecture, but domestic container buildings have poor public consciousness so as to be limitedly utilized as temporary structures based on economic efficiency. Besides, there is the lack of research and development on them. Particularly, despite the advantages of containers as housing facilities, the use of containers as short- or middle-term temporary housing is limited and does not spread. Also, compared to general housing, containers have lower quality of physical environment and even frequently bring about negligent accidents such as fire and electric shock. Thus, this study intends to identify the actual condition of using container houses, the problems in using them, and the direction of improving their residential environment. For this purpose, it analyzes the present condition and characteristics of domestic container housing, and derives conclusions from the focus group interview with 23 residents who have lived in Seoul and Gyeonggi-do for over a year about such survey items as daylighting, ventilation, privacy condition, water service and sewerage, insulation, soundproofing, view, and room scale.

도입까지 시간이 걸릴 것이라고 예측됐던 건설정보모델링(BIM : Building Information Modeling, 이하 BIM)이 어느새 성큼 다양한 분야에 진입했다. 영국, 싱가포르, 미국 등 해외에서는 이미 공공사업 시 BIM을 적극적으로 활용하고 있다. 우리나라 또한 2018년 국토교통부에서 '스마트 건설기술 로드맵'을 마련한 후 공공사업에 BIM을 단계적으로 도입해왔다. 대부분의 발주기관들은 오는 2025년까지 공공사업에 BIM을 전면 도입한다는 계획이다. 성균관대학교 공과대학 건설환경공학부 및 미래도시융합공학과 교수이자 국제건설자동화학회의 종신 상임이사인 권순욱 교수는 '스마트 건설 관리' 연구자이자 국내외에서 활동 중인 CM, BIM의 권위자다. 관련 분야의 책 8권과 100편 이상의 논문을 집필하고 30여 개의 특허·소프트웨어 등록을 보유하고 있다. 텍사스 오스틴 대학교 토목공학 박사 출신으로, 삼성물산, 한국건설기술연구원 등 일반 기업과 국가기관에서 실무와 이론을 두루 경험하며 경력을 쌓았다. 건설연구개발사업, 첨단 융복합 건설기술 등 다수의 국가 건설 R&D에 참여해 초고층 자재, 안전 모니터링, BIM 프로세스 표준개발 등의 시스템을 개발하기도 했다. 해외 연구자들과의 교류에도 적극적이다. 세계 석학들과 '노령 공학' 관련 영문교과서를 공동 집필(스마트주택 챕터 담당)했고, 2016년과 2019년엔 국제건설자동화학회와 국제프로젝트관리학회의 연사 자격으로 강단에 섰다. "영국, 싱가포르 등에선 공공사업을 100% BIM으로 발주하기 시작했습니다. 우리나라 정부도 비슷한 길을 가고 있습니다. 일정 규모의 발주 물량이 안정적으로 나오는 공공기관에서 그렇게 한다는 것은 국가가 전체 패러다임을 바꾸겠다는 의지 아닐까요?" 6월 10일 그의 연구실에서 권순욱 교수를 만나 BIM의 현황과 전망에 대해 들어봤다.

Recently, the Ministry of Land, Infrastructure and Transport presented the '6th Construction Technology Promotion Basic Plan' and 'Smart Construction Revitalization Plan (2022.7.20)'. Off-Site Construction (OSC), which involves construction and production of PC (Precast Concrete) and Modular, etc., has advantages in shortening the construction period, reducing costs, improving quality, reducing construction waste, and reducing safety accidents. However, the construction cost is high compared to the traditional RC construction method, which has hindered its utilization and spread. In this study, OSC utilization was improved. An economic analysis indicator and methodology that can support decision-making in the planning and design stages for multi-unit housing were proposed. The factors used in the economic analysis of OSC (based on the PC method) of apartment houses were reviewed. As for the indicators used in the cost and benefit section, 'Construction Period', 'Disaster Occurrence', 'Waste Generation', and 'Greenhouse gas Emission', which reflect the technical advantages of OSC, were derived. In addition, a scenario analysis was conducted based on actual apartment housing case data for the presented economic analysis indicators and benefit calculation standards. The level of benefit that offsets the difference between the existing RC construction method and the construction cost was reviewed. In future studies, it will be necessary to conduct additional case studies to apply the measurement criteria for detailed indicators and supplement the benefit indicators.
