Recently clients requirements and social requirements are complex and large sized in construction projects. Futhermore, processes and steps are more complexed than before. Unsuitable reflection of clients brings mistaken opinions. A phase of middle change makes delay and change. It brings problems of waste expense and time. 80, first stage of planning and schematic design processes have to reflect of clients opinion actively. by increasing of constructions project competitiveness. Recently, BIM(Building Information Modeling is being researched frequently. Through visualization of information proceed step by step and it helps cognition of adapting information. 80, this paper finds and suggests solution of reflecting clients opinion and requirements and non professional clients and positively support of client participation watching based on BIM.

The purpose of this study is to understand the architectural changes that occurred in the main space of Deoksugung Palace based on the Deoksugung Wonan. In the 1910s, constructions in the Deokhongjeon area and Hamnyeongjeon area caused a change in the main space of Deoksugung Palace, which is similar to the change in the central space of Changdeokgung Palace. In both palaces, the space composition, architectural structure, construction equipment, and architectural design of the palace were changed due to the changed architectural organization and construction system.

국방 및 군사시설 프로젝트에서는 설계변경으로 인한 계약금액 조정은 공사 비용의 증가와 공사 기간의 연장 등에 직접 또는 간접적인 영향을 미친다. 또한, 이는 군과 계약 당사자 간 의견 차이와 갈등으로 이어지기도 한다. 본 사례연구는 서울과 경기도 남부지역에서 육군, 해군, 해병대, 공군의 국방 및 군사시설 사업을 통합 관리하는 경기남부시설단 추진사업을 분석한 것이다. 본 사례연구는 공사가 완료된 388건의 프로젝트 중 설계변경이 이루어진 103건을 표본으로 분석하였다. 이를 통해 프로젝트의 완결에서 발생하는 설계변경 비율 등에 대한 신뢰성을 확보하고자 하였다. 본 사례연구는 기획재정부 계약예규 공사계약 일반조건에서 규정하는 설계변경 발생 원인별로 표본을 분류하고, 각각의 원인별로 발생률에 따른 순위를 부여하였다. 또한, 각각의 설계변경 발생 원인별 세부 요인을 분석하고 시사점을 도출하여 설계변경 발생 원인에 대한 개선 방안을 제시하였다. 이러한, 사례연구는 군의 원천자료 접근에 제한성이 있는 특수성을 고려해 볼 때, 국방 및 군사시설 사업에서 설계변경을 최소화되도록 하는데 기여 할 것을 기대한다. 아울러, 설계변경에 따른 계약금액 조정 등에 관한 후속 연구 등에 실증적으로 유용할 것이다.

This study is to suggest a strategy and trend of products development by major construction companies to form a trend and to set the trend in housing market through investigation about brand image campaign for TV ad, individual design items, result of products development and special plans. It is the strategy for products development of construction companies surveyed to be divided into five kinds. First, the change from in the unit to outside. Second, centralization of design powers about products development through submit and the wining of a prize in the domestic & foreign design fair to publicize a excellent quality in a roundabout way. Third, reinforcement of service for support the habitability and design manual for secure uniform quality. Forth, investment in the environment-friendly housing and new recycling energy. Fifth, reinforcement of organizational power for improving production capability.

Onsite usage of construction equipment accounts for a 6.8% of air pollution in Korea. The high concentration of carbon dioxide in such emissions impact not only climate change, but also people's health. However, greenhouse gas emissions from onsite equipment usage have not yet been fully investigated. This study presents a comparative analysis on how much greenhouse gas is generated by various equipment types used in different construction activities. Two ongoing cases which involve a typical road construction project in Korea were selected for the comparison purpose. Greenhouse gas emissions from each onsite equipment usage of the different activities were estimated on the ground of design documents. The estimates were compared and analyzed to derive the main sources of greenhouse gas emissions. The result showed that earthwork constituted the largest part-more than 90%-among work types. Dump truck, bulldozer, and loader were major sources for such emissions. The study results are expected to be used as a basis for reduction of greenhouse gas emission from onsite equipment usage.

In the 1950’s, after modernistic hospital is begun to build in our country, there were much changes in hospital construction plan such as function, scale, operation, technology for 40 years so far. Interest about 'Healing environment furtherance' which is one of basic function of hospital within these change is continued. Specially, concept about furtherance of healing environment limited in ward department in the early time is applied to hospital space magnificently whole coming at present. Entrance of hospital and change of Lobby may speak as the representative example. This interest about practically use of lobby is rising gradually. Lobby adds to existed concept of space to the importance revaluated. The first purpose of this study is to investigates main entrance and lobby of representative hospital in our country and to search change and present condition. The second purpose is hereupon to present necessary objective standard with direction of lobby plan in general hospital forward though this.

건축공사가 대형화됨에 따라 대규모의 지하공간을 구축하기 위한 흙막이 공사의 중요성도 점차 커지고 있다. 따라서 적정한 흙막이공법의 선정은 건축공사의 원활한 수행을 위해서 매우 중요한 요소 중의 하나라 할 수 있다. 그러나 흙막이공법의 설계와 시공이 분리되어 있는 우리나라의 경우에는 많은 설계변경이 발생하고 있고, 이러한 설계변경은 건설사업의 성패를 좌우하는 공사비와 공기 측면에서 지대한 영향을 줄 수 있다. 본 연구에서는 이러한 흙막이공법에 대한 의사결정 단계에서 활용할 수 있는 사례기반추론기법을 활용한 흙막이 공법 선정 모델을 구축하여 제안하고, 이를 실제 시공된 사례를 이용하여 모델을 평가하였다. 사례연구 결과 유사사례와 추천사례에서 비교적 정확한 결과를 도출하는 것으로 나타났다. 흙막이공법의 선정과 같이 의사결정과정에서 고려해야할 요소가 많고, 이러한 영향요소를 정량화하기 어려운 분야에서는 본 연구에서 활용된 사례기반추론기법이 매우 유용하게 활용될 수 있을 것으로 사료된다.

본 연구는 턴키공사의 문제점 가운데 설계변경에 있어 부실한 설계관리가 상당한 비중을 차지하고 있음에 착안하여, 당초의 설계물이 시공단계에서 설계변경을 초래하게 하는 제도적 문제점을 찾아보고, 현행 책임감리제도하에서 시공자가 수행하는 현장설계변경 절차를 ISO에서 권고하는 절차와 비교하여 그 개선 방안을 알아보고자 하였다. 설계변경상에서 나타나는 문제점으로는 첫째, 시공단계의 설계변경은 원 설계조직이 기술적 타당성, 전반적 완전성, 품질요건 등 사업 전체적 시각으로 검토하는 절차수립 및 이행이 요구되었으며, 둘째로 효율적인 설계관리를 위해서 사업의 조직 및 분장업무, 기술표준의 결정, 설계문서별 작성기준 등 설계계획 단계에서의 개선이 필요하며, 마지막으로 공동도급업체간 설계품질관리체계를 구축하여 설계정보의 공유, 사전검토, 확인 등으로 설계오류를 최소화하는 것이다.

Building Information Modeling (BIM) design has been mandatory in Korea since 2016, and it has been gradually expanding in the industry, with a slow attempt to apply it in remodeling constructions. This is because Korea is facing a situation where many buildings are over 30 years old and require remodeling or reconstruction. The remodeling industry is also a growing market, as it saves construction time and cost compared to reconstruction. BIM is an ideal technology element for a competitive remodeling construction, as remodeling constructions face a complicated construction process from the start, including demolition, maintenance, and reinforcement to save the change process. However, there are still limitations in applying BIM to remodeling constructions, due to considerations of the existing building and the complicated requests of the inhabitants. BIM still has technical and environmental limitations for general use. In this study, I analyzed BIM application cases from existing studies and suggest what improvement points should be strengthened.
