Although the modular construction method is safer than traditional onsite methods, accidents still occur; therefore, projects have characteristic safety risks. This study investigated accident cases related to and identified risk factors. The evaluated that occurred in United States from 2000 2018 analyzed factors, such as types causes of these cases. In process analysis, causal map was developed it used identify accidents. results analyses showed major activities. Second, this conducted a...
Modular construction, which involves unit production in factories and on-site work, has benefits such as low cost, high quality, short duration, resulting from the controlled factory environment utilized. An efficient tower crane lifting plan ensures successful high-rise modular project completion. For improved efficiency, should minimize reaching distance of crane, because this directly affects capacity, is related to operation cost. In situations where units are lifted trailers,...
Modular construction offers several advantages, such as safe working conditions, fast construction, and high-quality end products. The project scheduling of modular should consider the time involved in factory production, transportation, erection processes units given limited resources (e.g., number units, available workers) restrictions sequences manufacturing production on-site installation). However, current techniques previous academic approaches cannot deal with overall...
In modular construction projects, unit production and onsite work are conducted concurrently, enabling shorter duration, lower cost, improved quality. Because of the nature work, building design details should be determined early in phase, which requires information from participants. However, process for stick-built does not include such information, leads to errors design, as omissions conflicts participants, causing reworking phase. To reduce errors, an flow identified representing...
Off-site construction (OSC) offers a promising means to improve the efficiency of projects. However, lack experience and knowledge regarding its use results in errors design owing conflicts omissions considerations for OSC To mitigate these problems, manufacturing assembly (DfMA) is widely used include process. Several studies concerning DfMA application have been performed, but comprehensive process not suggested mitigating aforementioned problems. This study proposes an by integrating...
Modular construction projects involve concurrent manufacturing production and processes for constructing the main structure foundation, on-site installation, finishing work. Using process-driven project scheduling, it is difficult to analyze how different issues affect overall schedule determine alternative solutions based on what-if scenario analysis (WISA). This paper proposes classification of modular building as driven, or a combination improve scheduling strategies schedule-driven...
The public housing demand in Seoul has been continuously increasing, but the available land for is insufficient. To meet demand, government planning to develop small-scale urban areas through various methods. Construction activities increasing capacity cause negative environmental impacts, and this inevitably leads an increase number of civil complaints. complaints can be mitigated by using offsite construction (OSC) fabricating components. However, OSC remains underdeveloped Korea owing...
Modular construction offers benefits such as high quality, low cost, and short durations owing to the productivity of repetitive production. To maximize productivity, modular involves schedules; however, scheduling methods exhibit limitations when applied on-site work. These are optimized by adjusting production rate activities; bounds rates work limited because workspace in units varying amounts between activities. This results idling time methods. Thus, this research, parallel station...
최근 건설 기업들은 노동력 부족, 원자재값 상승, 건설경기 위축 등으로 인해 새로운 건설시장 개척 및 자동화 기술도입을 적극적으로 추진하고 있다. 이러한 노력의 일환으로 제조업의 생산프로세스와 건설생산프로세스가 결합된 모듈러 건축공법이 부각되고 있으며 이와 관련된 연구가 활발히 진행되고 건축프로세스에서 공장제작의 가장 큰 장점 중 하나는 기존 사용하기 어려웠던 생산설비시스템을 활용한 생산원가(공사원감)절감이 가능하다는 것 이를 뒷받침하기 위해서는 대다수의 건축공종이 집중되어있는 공장제작단계에서의 원가산정이 정확해야 하며 특히 직접적인 계산이 어려운 간접비에 대한 구체적인 산정방인 필요하다. 그러나 국내 건축산업이 시장도입단계로 한정적으로 이루어지고 있어 건축물의 원가왜곡현상이 나타날 수 있는 문제가 따라서 본 연구는 공장제작단계에서 국내계약법상에서 명시된 제조업과 건설업에서의 간접비 정의를 고찰하고 활동기준원가계산법을 통해 건축물을 구성하는 유닛별 산정방식을 제시하였다. 전...

2008년 글로벌 금융위기 이후 국내의 주택시장은 침체기를 겪고 있으며 이에 따라 주택가격의 하락, 임대주택가격의 상승등과 같은 주택시장의 문제점이 발생하였다. 정상화를 위해 정부에서는 다양한 주택정책을 발표하였으나 아직 회복세를 보이지 않고 있다. 따라서 본 연구는 침체 원인 분석하기 주택 시장의 주요 참여자인 주택공급자와 수요자를 기존의 수요 공급 원리에 의해서 분석하며 이들의 거래의사에 영향을 미치는 심리적 요인을 행동경제학 이론을 바탕으로 분석한다. 이의 분석 결과를 시스템다이내믹스 시뮬레이션 방법론을 사용하여 발표된 정책의 실효성을 검증한 결과 입안 기간에 거래량과 주택담보대출 총액이 받는 것으로 나타났다. After 2008 global financial crisis, Korean housing market has experienced stagnation. So it caused problems like price reduction, rising rent cost...
