Because designers want to express various elevation, architectural concrete has recently paid attention to finish material and has increasingly used in the construction. architectural concrete needs more careful and professional supervision works such as controling quality of color, texture, construction plan, and design plan. none the less, It is not clear to define process and manage methods for the construction life-cycle, which causes the expense to increase and the quality to be poor. this study will analyze concrete finish method by dividing three parts which are common, exposed and architectural concrete finish method. definition and the limit of application in architectural concrete finish method will be present by comparing three methods. Throughout an interview with a staff in charge and a case study, this paper shows the requirement and the keynote of management which are divided by three steps; the design, construction and maintenance. finally, this research provides management methods of individual steps for effective construction.

The construction of Pusan National University Yangsan Hospital is a new construction of a medical town in Yangsan. It is a case that CMr participated in the project from planning to post-completion. It shows an actual proof of Construction Management business applied CM by each phase. In this case, CMr selected the design-build contractor in the planning phase and technically performed CM businesses in every single phase such as design and construction schedule management regarding application of Fast Track technique, procurement management and contract administration in phases based on the Fast-tract; technique, design review, VE in the design phase, change order management in the construction phase and operating and maintenance in the post-construction phase. This study would go far toward applying CM to Mega Turnkey projects by analyzing the problems of CMr's practical application to the project and providing guidelines for effective and efficient CM business implementation especially in the Turnkey projects.

In Korea construction project case, architectural construction project is curtailed production because information network process within multidisciplinary isn't smooth. Particularly, the construction is not insufficient about performance, cost and material, construction process, etc. in result various question arises because of design error in construction step. And various mistake is made because communication path within multidisciplinary isn't smooth in architectural design and design change process. This research proposed the optimization method of building system which is satisfied with performance of building, cost, constructability, and proposed the information management plan which is connected with that. And The construction information in this research is restricted to design/construction information which is considerate in design step.

소방산업의 분야는 크게 소방시설의 설계와 감리, 시공, 점검관리, 소방기구의 제조 등으로 나누어 볼 수 있다. 근래에 들어 우리 소방산업은 학계, 업계 및 연구기관을 중심으로 지속적인 발전을 가져오고 있는 것 또한 사실이다. 그러나 소방시설의 시공 분야 중 시공관리 부분은 아직도 체계적이지 못한 것이 현실이다. 그러기에 시공관리 부분의 입문자는 실무에서 직접 배워야 하는 것이 현실이다. 이에 본 논문에서는 실무를 중심으로 소방시공관리 체계를 구축하였다.

본 고에서는 막구조의 설계, 시공, 유지관리에 대해 개략적으로 기술하였다. 막구조는 그 여러가지 특성이 아직 규명이 안된 부분이 많고 시공오차가 비교적 큰 편이므로 막 재료의 역학적, 재료적 특성에 대한 연구와 형상해석 모델의 공식화, 막재단의 컴퓨터화가 필요하며 초기장력 도입에 따른 시공과정의 해석이 더욱 필요하다. 따라서 설계, 형상해석, 재단에서 시공 및 유지관리에 이르는 일괄적인 System의 개발이 시급하다 하겠다.

The design with construction knowledge and experience can eliminate inefficiency in the process of construction and improve productivity in all phase of construction project. To utilize constructability knowledge most effectively in design phase, the information must be made available to the design team at the proper point in time. Current methods for effective utilization of constructability knowledge have focused on the structuralization of constructability knowledge such as checklist, which lack the consideration of the proper point in time. However, constructability knowledge which is used at the inapposite point in time consequently leads to unnecessary rework. To minimize this inefficiency and improve productivity, project manager needs to consider the design process and know what constructability knowledge is required for specific design activities. This paper therefore presents a design process management using Dependency Structure Matrix (DSM) that focus on information flows between design activities and constructability knowledge. We expect that the results of this paper will support that design process management become comprehensive management related to every phase of construction project beyond design review or inspection in design phase, and be used as a basis of the integration of design and construction.

Roadway construction planning processes involve a large amount of information on design, construction methods, quantities, unit costs, and production rates. GIS (Geographic Information System) is a strong tool for integration and managing various types of information such as spatial and non-spatial data required for roadway construction planning. This paper proposes a GIS-based system for improving roadway construction planning with its 'Spatial Analysis' and 'Visualization' functions. The proposed system cail help construction planner make a proper decision in a unique way by integrating design information and construction information within the system and creating design element modules for space scheduling purposes in real-time with its 'Interactive Planning' function.

본 터널 붕락 사례 연구를 종합적으로 분석해 볼때, 시공 공정 중에 발생 가능한 붕괴 및 붕락은 앞서와 같이 과거의 여러 사례들을 토대로 분석함으로서 예측 할 수 있지만, 시공 외적인 요인에 대해서는 사실상 조사, 설계, 시공 중의 오류에 의해 발생되는 것이기 때문에 파악하기 어렵다. 본 터널 붕락사례를 통해 원인을 분석 정리 하면 다음과 같다. (1) 불규칙한 지반구조적 원인 대부분의 터널 붕락을 일으키는 불규칙한 지반구조는 과거 지반구조의 침식 또는 대규모 지반운동 등 지반구조의 급속한 변화에 기인한 것이다. 터널 시공전에 면밀한 사전 지반조사와 선진 보오링 등으로 정확한 지반구조를 파악한다면 이로 인한 터널 붕락은 최소화 시킬수 있다. (2) 기획과 설계단계에서의 오류 충분치 못한 지반조사에 의한 설계 및 부적절한 시공자재 사용등으로 터널 붕락이 발생 될수 있다. 터널 굴착 주변 지반조건과 이러한 지반조건에 적합한 터널 굴착 및 보강공법 등이 터널 설계시 심도있게 검토되어야 할 가장 중요한 요소이다. (3) 시공 및 관리에서의 오류 경험이 부족한 터널기술자의 현장 감독과 현장에서 수집되는 각종 계측자료의 신뢰성 부족과 결과의 재적용 미흡으로 효율적인 계측 및 지반정보를 활용한 정밀 시공이 이루어지지 않는 것도 터널 붕락의 중요한 요인으로 분석되었다. (4) 현장관리 조사서의 표준화 부족 터널굴착공사중 붕락이 발생된 현장의 막장조사결과를 보면 조사자가 임의로 표시를 하여 각 터널별 막장조사결과가 매우 상이할 뿐만 아니라 각 터널별로 기재방법, 양식이 달라서 실제 원인분석에 활용하기가 어려운 것으로 분석되었다.

Although pilot projects have been actively carried out from 2017 to present to institutionalize CM at Risk, one of the major tasks for innovation in the construction industry, standards and processes related to Design VE, a key tool for determining GMP in the pre-construction phase, have not yet been established. Therefore, through research and operation status related to CM at Risk and Design VE, and survey on project participants' perception, the problem of the existing design VE process was derived, and the design VE process suitable for the CM at Risk project was proposed. The application plan was proposed in three aspects: Schedule, Cycle, and Process, and the appropriateness and applicability were verified through FGI. The results of this study are expected to be used as basic data on the establishment and legislation of order standards to be made in the future.
