Large scale construction disasters such as recent Noryangjin flooding incident and Banghwadaegyo collapse accident are occurring persistently. Thereupon, the role and responsibility of the various construction participants are considered as major element to reduce disaster at the construction site. Construction industry is a process of building construction object by going through planning, designing, constructing, and maintenance controlling in which various bodies of act, from contractor to designer and builders, participate. However, the subject of current safety supervision is focused on the builder, the contract enterprise which directly employs workers, while the safety activity participation of the contractor, who exerts decision-making authority at the highest level, is excluded. Therefore, this study understands the level of awareness and reality on the safety activity of each construction participants from which the improvement plan on the contractor centered safety management system is proposed.

The purpose of this study was to propose the participation of consultant pertinent to ground situations. The careful consideration of participating consultant reduces life cycle cost. duration and improves quality. The first step is studying Curtain-wall construction process by researching the documents, and Second step is analyzing Curtain-wall construction's problem through having a interview with a concerned experts (Architect, Gene-con, Sub-con. Consultant). Then we study how consultant solves the problem, propose the way of participation of consultant. The way of participation consist of three phases. the first one is to participate in design & construction process and the second one is to participate in design process, the third one is to participate in construction process. These participations are decided by evaluating project, design phase. construction phase. The verification of these participating strategies was implemented by the interview with the experts.

해체공사는 작업의 특성상 단기간에 이루어지며, 해체공사 현장에 투입되는 근로자는 일용직 근로자가 대부분으로 안전사고의 비율이 높다. 사업장 위험성 평가에 관한 지침에는 위험성 평가시 근로자를 참여토록 하고 있으나 해체현장의 특성상 근로자가 참여한다고 하여도 위험요소를 파악할 역량이 부족할 따름이다. 또한 기존의 해체공사 안전관리 매뉴얼은 구조안전성 확보를 위한 매뉴얼로 해체 근로자의 안전을 위한 매뉴얼은 없는 실정으로, 근로자의 안전을 확보하기 위한 위험성 평가 매뉴얼이 요구되고 있다. 이에 본 연구에서는 건설공사 안전관리 종합정보망(CSI)의 해체 및 철거공사의 사고사례를 분석하였으며, 해체 및 철거 사고시 발생한 주요 위험요소를 도출하여 작업 공종별로 유해·위험요인의 파악을 손 쉽게 할 수 있도록 하였다. 또한 해체 현장 규모에 따라 대규모 현장은 빈도·강도법, 중·소규모 현장은 체크리스트법을 활용하여 위험성을 결정하고 감소대책을 수립할 수 있도록 매뉴얼을 구성하였다. 잔여 위험에 대해서는 관리카드를 만들어 해체공사 완료시까지 관리하도록 하였다.

The participants of steel works should exchange a variety of information with others through documents. However construction steel works in the multistage contract system has a difficulty in exchanging information through the documents promptly. So if the trouble as change orders arise, conducting steel works will take much time, and the participants may not discuss the trouble sufficiently. Consequently this study improved the current business process of steel works. And this developed business support system(XCOS) based on XML so that participants of steel works achieve a successful management of steel works through conducting business rapidly and correctly.

도시재생사업은 주민참여를 중심으로 커뮤니티를 재생시키려는 목적을 갖지만 공람, 공청회 등 현행 주민참여방식은 형식적 수단에 불과하다는 한계를 지니고 있다. 이에 따라, 본 연구에서는 정책결정자, 전문가 그리고 주민이 서로의 생각을 교환하고 이해하는데 유용한 의사소통 도구 및 재생사업의 적극적인 추진 매개체로써의 공공참여 서비스 모형을 수립함으로써 능동적인 공공참여를 이끌어낼 수 있기를 기대한다.

서해안 최고의 동백정해수욕장과 마량리 동백나무숲은 1970년대 오일쇼크 이후 에너지 자립을 위해 발전소를 건설하면서 사라졌다. 그 당시 준공된 화력발전소는 전력공급 이라는 소임을 완수하고 2021년 부터 동백정의 아름다운 옛 모습 그대로 지역주민에게 돌려 주기위한 친환경 사업으로 발전소 철거공사를 시작, 동백정 복원공사를 추진 하기로 했다. 고층 및 중량물의 건축물 및 구조물을 안전하게 해체하기 위해서는 국내 최초 발전소 철골구조물에 대한 발파·전도공법을 채택 하였다. 철거작업은 고위험 공종으로 참여 주체인 발주자, 설계자, 감리자, 시공자 및 근로자 전 계층의 참여로 사전 위험성평가를 통해 근원의 위험요인 발굴 및 안전대책 수립, 수립된 안전대책 100% 이행을 통해 무재해 준공 달성 하기를 기대한다.

As construction project has been becoming larger, specialized and complicated, it is important to utilize a lot of information that is made by diverse participants. Especially this information is mainly produced in construction site that plays a leading role in construction project. The problem of information exchange between participants of construction site causes decline of construction productivity. So as to resolve this problem, there is a many interest in BIM(Building Information Modeling) that makes and manages a necessary data during building life cycle. But in Korea construction industry, applying BIM in construction phase is less active than in design phase. Through studying previous research, this study classify the main cause of failure related to information exchange in framework construction. And by interviewing expert, it draw a work that is possible to apply BIM. Next through analyzing framework construction site that is applied with BIM, this study proposes specific information flow model for supporting work by BIM.

This study proposes a scheme for successful remodeling projects by establishing the task and role of project participants. In doing so, the study investigates the natures and problems of the current remodeling practices through interview and questionnaire survey with experts. This study establishes the critical phase of remodeling process and defines the task and role of project participants at each phase. The related documents of being generated at each phase also match up the task and role. It is expected that this scheme can be applied to deal with conflicts, cost overruns, and delays of time.

In this study, we attempted to derive major management factors related to the quality control of formwork and identified differences in the perceptions of construction engineers, construction managers, and field workers about the importance and performance of the derived factors. As a result of the study, 18 management factors related to the formwork were derived. Among the derived factors, the field workers placed importance on the factors that influence the detailed process of the formwork, while construction engineers placed importance on the factors related to the judgment of the progress and completion of the construction. The construction managers placed importance on the factors that affect the quality of the building frame. Based on the results of this study, it is expected that a plan to improve the quality of formwork that accepts the various opinions of each participant will be established.

The purpose of this study is to forecast future changes in the construction market following the reorganization of the construction production system by analyzing the possible market size in which general contractors and specialty contractors may participate in each other, and by carrying out a survey. The ratio of correlation between general construction and specialty construction industries was derived by analyzing the relevance of work area of general contractors and specialty contractors, the similarity of registration standards, and the market in which general contractors and specialty contractors may be able to mutually participate. In order to overcome the limitation of previous studies which analyze the changes in construction market based on the statistical data, and to analyze in more detail the impact of reorganization of construction production system from market participants' view, a survey targeting general contractors and specialty contractors for their willingness and method of participating in the mutual market was conducted. As a result of the survey, it was found that 52% of general contractors were willing to participate in the specialized construction market and 55.1% of specialty contractors were willing to participate in the general construction market. It was found that there was a high willingness to participate in the earthworks, reinforced concrete works, facility maintenance and management, water and sewage facility works, and interior works, and high competition is expected for projects with a scale of 500 million to less than 3 billion won. Through this study, it will be possible for general and specialty contractors to understand the changes in the construction market due to the reorganization of the construction industry production system, and to respond effectively to these changes.
