Temporary constructions are defined as constructions for temporary use, but frequently they are used long like permanent constructions and connected with main constructions. In this case, fire hazardousness increase. But there is no way to control this hazard in our system. This study include investigation of present related law survey about sample complex, collection of related lawsuit result and estimation of hazardousness of each contemporary construction type. The conclusion is that the article that specify distance between main construction and temporary one should be created in the architectural law. Or to apply fire service law to area of temporary construction, fire service law should be changed properly.

With the recent changes in building environments such as low-carbon green growth, there have been increasing demands for the new building system that is eco-friendly and can maximize efficiency such as the unit modular system. For the unit modular system, more than 80% of the whole process is carried out in the factory while in the field, mostly unit module assembling and finish work are done. Thus, the quality at the pre-construction stage when design and manufacturing are done determines the quality of the building as a whole. In the country, the unit modular method was first applied in 2003 to school buildings and has gradually expanded afterwards, but due to the lack of examples and related information as well as the small scale of modular manufacturers, its characteristics have not been sufficiently reflected in design, manufacturing and field constructions. This study, as an attempt to improve the design quality of unit modular buildings, points to the problem in manufacturing and field construction, compares and analyzes its causes, and suggests major points to be considered in the early stage of designing the unit modular buildings.

Modular construction is combined with manufacturing production process and conventional construction industry technique. Considering characteristic of modular construction production process, manufacturing facilities require indirect costs for utilities, equipment, and overall maintenance, which can affect modular units pricing. However, current modular construction cost classification is inadvertent to reflect the manufacturing overhead costs, because it is generally added as a percentage to sum of labor, material and equipment as it called in single cost pool used. This process is easy to estimate the total construction cost at the project starting points, but it brings on misunderstanding of project profit estimations by "cross subsidization phenomenon". To prevent this situation, in this research aims to provide modular construction overhead cost handling process at the detailed indirect cost calculation for manufacturing stage using Activity-Based Costing as one of the powerful method for overhead costs estimation and allocation. Using this research results, modular construction cost estimators have more detailed cost information of modular units and prevent to misallocate indirect costs. Also, it can be utilized to aid the understanding of the company's profit structure.

최근 수도권에서는 지방공단 등으로 이전한 노후 공장 건축물을 철거한 자리에 '테크노타운', '벤처타운', 'IT타워', '디지털밸리', '테크노밸리' 등의 이름으로 아파트형 공장을 설립하고 있다. 아파트형 공장은 서울을 중심으로 수도권역에서 토지이용을 극대화가기 위한 집합 공장건물로서 중소기업체의 입지 해결 및 쾌적한 작업환경을 제공하고 도시근로자의 풍부한 노동력을 적극적으로 활용하고 있다. 또한 공동 부대시설을 확보하여 공간효율의 극대화와 종업원의 복리후생이 개선되는 등의 중소기업 지원효과를 거두고 있다. 고층화, 집단화, 공동화를 주요 특징으로 하는 아파트형 공장에서 부속시설의 화재보험요율 적용에 관하여 생각해보고자 한다.

Specification is an important document for securing safe construction and improving quality as well as the contract document. Currently, the specifications used in modular buildings in Korea are only the construction specification, and most of the contents are used by borrowing the standard specifications of the building, so the contents of the modular buildings can not be reflected and it is contents are similar to the guideline book. The current status of domestic specification for modular buildings is affecting the quality of modular buildings. Therefore, we analyze activity through monitoring the modular process of modular buildings and analyze systematically relationship by applying IDEF modeling with analyzed activity. As result this paper proposes a structure of special specification specialized in modular building through generalization. The major classifications were divided into three stages : factory construction, transportation, and on-site installation. The specification structure was divided into 32 types of construction items from the floor slab assembly of the factory production to the joint finish of the on site installation in accordance with the opinion of experts.

In this study, we investigated whether the evacuation time according to the exit installation standards specified in the building code during a food factory fire is compatible with the evacuation time based on the performance-based design specified by the fire department, in order to determine if evacuation safety is ensured. We used the Pathfinder program to confirm the evacuation time, and experimented with three scenarios for exit installation standards towards the outside of the building: 60m, 80m, and 100m. The target building in the experiment corresponded to the building code's exit installation standard of 100m from each dwelling. The experimental results showed tt in the cases of 80m and 100m, ASET exceeded RSET, indicating tt evacuation safety was not ensured, while in the case of 60m, evacuation safety was maintained. Through this study, it was confirmed tt even when the exit installation standards towards the outside of the building are met, evacuation safety may not be guaranteed.

Recent research has been ongoing for modular buildings in the country and interest increases. However, the activation of modular building projects is obstructed in the construction industry. There are many reasons to identity for this obstruction but one issue should be focussed. Modular buildings require to change the existing construction production system to a new construction production system, which is factory production - transportation - erection. However, the existing project delivery system in the public sector could not be adapted for this new construction production system due to the obligation of multi prime contract use, such as electrical, communication, fire fighting contracts by Law. Therefore, modular buildings in the existing project delivery system are separately contracted by multi prime contracts and modular units composed of the buildings are contracted by an architectural prime contractor as a commodity. As results, construction costs are increased, potential quality problems are raised and the existing project delivery system is finally an obstacle not to maximize benefits of the modular buildings. In this paper, we propose a new project delivery system for the modular buildings to adapt then ew construction production system.
