With the ever-increasing important of high-speed information in society as we move towards the 21 st century. Interior design and it's working condition has been changed a great deal included a sort of each special character and make a difference against the others. It used to be find a great poles asunder of worker's safety and project quality according to the environmental dimension of interior construction field as if they should be a pleasantness or poor condition. This research aimed to improvement of environmental construction field of interior with construction engineers and particular interior labors in 4 phases as : ⅠThe preparatory phase : -Secure a Budget, Environmental safety supervisor -Fix of Design quality, Construction period. -Choice of Construction method, Sub constructing Ⅱ. Starting work phase ; -Capacity , Safety of temporary power line. -Carriage, Stock of Material -Safety of Electronic tools, -Personal protector. Ⅲ. Working period ; -Ventilation, I illumination of working place. -Measurement of environmental working condition Ⅳ.Finish working phase ; -Analysis of measurement data. -Evaluation and making up for the weak point. -Keeping data.

최근 공사규모의 대형화, 복잡화 등으로 토목, 건축, 기계 등의 복합공종으로 구성된 공사들은 공기절감을 위해 패스트트랙(Fast Track) 방식으로 진행되는 사례가 많으며, 패스트트랙 방식에서는 적정 단계구분이 전체 프로젝트의 공기 책정에 중요한 사안이다. 본 연구에서는 복합공종으로 구성된 건설공사가 패스트트랙으로 진행될 때 적용할 수 있는 단계구분 방식을 제시하고 있다. 이를 위해 연구에서는 토목, 건축공사로 구성된 4개의 축구전용경기장 공사를 적용 사례로 분석하여 세분화된 공정분류체계(Work Breakdown Structure, WBS)를 통해 주요 단계별 공정 구분에 의한 일정표를 분석하고, 5가지 시안을 적용하여 패스트트랙 단계구분의 적정성을 분석한다. 분석된 시안중에서 최소 공기를 갖는 시안에 대하여 패스트트랙 단계구분 및 단계별 주요 공정의 구성 모형을 제시하였다. 이러한 방법론은 패스트트랙이 적용되는 유사한 규모의 대형 복합공사에서 패스트트랙 적용 시에 적정 단계 구분과 단계별 공정 구성 체계에 활용성을 가질 수 있다.

This paper proposes a technical requirements analysis of implementation of multi-trade prefabrication. Recently, there has been a rise in the use of prefabrication to minimize on-site work for time reduction to increase productivity. Prefabrication technique is evolved into multi-trade prefabrication combining other trades from single-trade prefabrication. For implementation of new technique, not only itself but complementary techniques have to be prepared. In this paper, MEP corridor rack, a major item of multi-trade prefabrication, was implemented in the test bed and its process was analyzed to find out technical requirements. As a result, comparatively high level of IT technique was required for efficient use of multi-trade prefabrication in design, lifting and construction phase. In design phase, component level of BIM library was needed for manufacturing; and in lifting phase, BIM-based site logistics process was required. Also in construction phase, laser scanning was implemented for gathering shape and geometry of the wall and slab that were attached to multi-trade prefabrication module.

The Build-Transfer-Lease (BTL) projects have rapidly increased under the Government support during recent years. This paper presents the risk analysis of factors affecting BTL projects in the initial phase. This study resulted in 10 significant risk factors influencing on each phase of BTL projects and then factors were grouped into each phase. The sensitivity analysis was also performed to identify risk factors with more significant influence on BTL projects. The results may useful to practitioners in order to cope with risks in initial phase of BTL projects. The paper resulted in the distribution of risks to project parties, thus it can be used as standards for risk assignment to competent authorities and private enterprises of BTL projects.

변화와 혁신의 가속화로 산업과 비즈니스에 대한 창의적 접근에 대한 관심이 높아지고 있으나 공공의 영향을 받는 건설산업은 상대적으로 이러한 창의적 접근에 대한 연구가 미비하다. 설계VE 역시 효율성 증대를 위한 창의적 접근에 대한 연구가 진행되고 있으나, 기법제안에 그친 경우가 많아, 실무적용 가능성에 대한 실증적 연구가 필요하다. 본 연구는 새로운 아이디어 창출 방법으로 BCC(Business Creativity Codes)사고체계를 소개하고, 이를 반영한 개선된 설계VE 아이디어 창출 프로세스를 제시하였다. 또한, 실무 종사자를 대상으로 BCC의 11가지 창의코드를 활용한 VE모델 분류실습과 설문 및 집단면접 등을 통해 BCC사고 체계의 유용성과 활용 가능성을 검증하였다.

Building Information Modeling (BIM) and modular construction are regarded as important technologies that could contribute to overcoming the crisis faced by the construction industry. However, BIM uptake in current modular construction projects is limited. Moreover, there are no specific guidelines to support decision-making regarding the application of BIM in modular construction projects. Therefore, this study aims to analyze the possibility for BIM uptake in each phase of modular construction projects in Korea. Initially, the literature detailing on BIM uptake cases in modular construction projects was reviewed. The detailed work and activities for each phase of a modular project were analyzed via a questionnaire targeting domestic modular experts, to derive items requiring improvement due to errors or changes occurring in the actual project. Ten realistic BIM uptake items were derived, reflecting the results of literature review and expert interviews. Then, the BIM uptake items in each phase were analyzed in terms of necessity and efficiency via a second questionnaire using five-point Likert scales. Finally, the BIM utilization index (BIM UI) of the BIM uptake items was suggested as a priority measure. As a result, the BIM UI of "3D coordination" (U2), "design authoring and reviews for off-site fabrication" (U3), and "detailed 3D modeling for off-site fabrication" (U4), were assigned the highest priority. The results of this study can be used as guidelines to support decision-making regarding the application of BIM in modular construction projects.

Current MEP designs are mostly applied by 2D-based design methods and tend to focus on simple modeling or geometry information expression such as converting 2D-written drawings into 3D modeling without taking advantage of the strength of BIM application. To increase the demand for BIM-based MEP design, geometric information, and property information of each member of the 3D model must be conveniently linked from the phase of the Design Development (DD) to the phase of Construction Document (CD). To conveniently implement a detailed model at each phase, the detailed level of each member of the 3D model must be specific, and an automatic generation of objects at each phase and automatic detailing module for each LOD are required. However, South Korea's guidelines have comprehensive standards for the degree of MEP modeling details for each design phase, and the application of each design phase is ambiguous. Furthermore, in practice, detailed levels of each phase are input manually. Therefore, this paper summarized the detailed standards of MEP modeling for each design phase through interviews with MEP design companies and related literature research. In addition, items that enable auto-detailing with DYNAMO were selected using the checklist for each design phase, and the types of detailed methods were presented. Auto-detailing items considering the detailed level of each phase were classified by members. If a DYNAMO algorithm is produced that automates selected auto-detailing items in this paper, the time and costs required for modeling construction will be reduced, and the demand for MEP design will increase.

The purpose of this study is to fully understand the present state of the domestic construction companies, and to analyze phased business types and construction management techniques in order to initiate overseas expansion. Because of the recession in the domestic construction market, a thorough and strategic perspective to constantly develop inroads into overseas market is required. So we carried out a questionnaire survey targeting the experts of the overseas construction and researcher, and consulted them in depth. The questionnaire survey was divided into three sections. The first section is the necessity of overseas construction and the reason. The second is the overseas business types classified into the way of advance in short-term and long-term phase possibility of expansion. Lastly, the importance of the phased construction management techniques and the current capacity of the domestic and the foreign business trends were scrutinized. On the basis of the consultation and surveys, we analyzed the overseas business types and the construction management types in the short-term and long-term phase.

As construction projects get bigger and more complex, communication and information flow among participants become key success factors of a project. Accordingly, construction projects to respond to these changes being made in the introduction of BIM (Building Information Modeling). But as 2D drawings are still to be widely used in practical fields, it is very important that 2D drawing information could be easily and clearly projected from 3D BIM data. In this study suggest that efficiency of design phase in BIM-based construction projects for can cause confusion and additional work in traditional to BIM.
