Facade structure system plays an important role in modern architecture and design. Many contractors start using Building Information Modeling (BIM) to help design and lay-out façade walls in recent years. However, there are still some users refuse to accept BIM on façade construction. Therefore, we employed Technology Acceptance Model (TAM) to assess the users acceptable of BIM work flow, with using a practical case of facade construction in Chongqing Wanda City. The factors that will affect the builder's decision of whether using BIM or not when construct façade, and the relationship among them will be found via this model. Through the analysis using TAM, this research found that the direct factors influencing the completely acceptance of BIM in façade construction is the BIM quality and Result Demonstrating, and the parameter impacting the intuition engendering is the Exterior Condition. Therefore, this paper proposes a more systemic model of BIM acceptance in curtain wall to analyze the user's acceptance. The solution can also offer a reference for future research and construct on façade structure. The acceptance model has the significance that it can help to analyze the reason why users refuse to use BIM in façade construction, thus to help users accept BIM.

본 연구에서는 가상건설시스템 개발 연구를 통해 구축된 BIM 기반 구조설계 프로세스와 개발 시스템을 적용하여 오피스 건물을 대상으로 사례 연구를 수행하였으며, 그 결과로부터 프로세스 및 개발 시스템의 적용에 따른 업무의 생산성과 경제성을 평가하였다. 사례 연구는 강구조를 주요 대상으로 하여, 구조해석모델 및 기본설계도서를 시작으로 기본실시모델과, 실시구조모델의 생성을 단계적으로 수행하였으며, 완성된 실시구조모델을 IFC를 이용하여 통합모델을 구축하여 다양한 BIM 설계도구와의 상호운용성을 검토하였다. BIM 프로세스를 구축하여 업무환경을 효율적으로 개선할 수 있었고, 접합부 모델링 자동화로 업무의 생산성을 향상시킬 수 있었다.

In the case of relatively good ground and construction condition in the deep excavation for the construction of subway, railway, building etc., flexible earth retaining systems are often used in an economical point of view. It is generally known that the mechanism of behavior in the flexible earth retaining system is relatively more complicated than the rigid earth retaining system. Moreover in the case of long span strut supporting system the analysis of strut axial force change becomes more difficult when the differences of ground condition and excavation work progress on both sides of excavation section are added. When deeper excavation than the specification or installation delay of supporting system is done or change of ground condition is faced due to the construction conditions during construction process, lots of axial force can be induced in some struts and that can threaten the safety of construction. This paper introduces one example of long span deep excavation where struts and rock bolts were used as a supporting system with flexible wall structure. The characteristics of ground deformation and strut axial force change, the measured data obtained during construction process, were analysed, the effects of relatively deeper excavation than the specification on one excavation side and rapid drawdown of ground water level on the other excavation side were deeply investigated from the viewpoint of mutual influences between ground deformations of both excavation sides and strut axial force changes. The effort of this article aims to improve and develop the technique of design and construction in the coming projects having similar ground condition and supporting method.

Purpose: This study, by comprehensively the characteristics of new Hanok application techniques with the proposed site application technology in the course of the design changes that have been accumulated through Hanok technology development the second stage business, by analyzing the range of reflection, new Considering the direction reflects the efficiency of the new Hanok application techniques. Method: new Hanok application technology, it was been established through research and development of large 1 new Hanok technology it has been proposed through the "site-specific application techniques" and 2 builders and designers "space-time proposed technique" Analysis of the case, at the center of the design changes, the land the body of laws and regulations, the requirements of the public buildings, compared to the construction method and the like for the reduction of construction costs, new Hanok applied technology in the process of change by it There was analyzed whether acceleration on the range and step which is reflected in the design Result: The result of new Hanok applied technology was built through the demonstration build business case, process another major technology, foundation, woodwork, walls, roof, has been reflected in the ceiling construction, the inclusion of items in the proposed technique of construction , it was applied to the main steps in general, except for other construction work landscaping. Application techniques and construction proposal technology research team has presented, show the difference between the scope and method. With significance effort to improve the unreasonable traditional methods of these core processes that can be reflected in the field repeated the construction proposed technique as a result of the utility that can be applied for substantial construction.

기획단계에서의 공사비 예측은 타당성 분석, 예산 책정, 계획수립 등을 위한 기초정보를 제공한다는 점에서 성공적인 프로젝트 수행을 위한 중요한 요소이다. 본 연구에서는 초기 기획단계의 신한옥 공사비 예측 정확도 향상을 목적으로 전체 공사비 중 가장 많은 비중을 차지하는 목공사는 다양한 조건(구조형식, 지붕형태, 평면형태 등)에 의해 개략 물량을 자동 산출하여 공사비를 예측하고, 이외의 공종은 단위단가식을 적용해 공사비를 예측하는 모델을 제시하였다. 2개의 사례를 대상으로 개략 견적 모델로써의 활용성 및 타당성을 검증하였으며, 총공사비의 오차율은 각각 -4%(사례 1), -6%(사례2)로 나타났다. 이러한 결과값은 초기 기획단계에서 실무활용 가능한 범위에서의 오차를 보였다.

In order to maintain and protect professionalism in color planning, the present study examined the process at the time of realization of color through color inspection and supervision in the actual construction site and suggested plans for improvement. Reflecting the characteristics that the governing body of the construction site is not a private person but an organization, the present study aims to provide institutional measures so that the supervisor of color construction at the actual site of construction can propose concerns related to proper construction at the right time, and the matters cannot be decided from the perspective of a layman. The institutional measures are proposed through the case of application of a process at the construction stage of the color planning at the construction site of Muju Taekwondo Park. First, the process clarified where the responsibility lies by specifying special conditions concerning color inspection on the field guide and color contract. Second, the sample for building materials was selected after obtaining it from a company capable of supply and is appropriate for the planned unit cost so that it could play an important role in realizing colors at the stage of basic design. Third, the process of construction was ensured not by temporary selection of colors but by continuous approval of colors in consideration of the conditions of construction site through letter of approval of color at each stage and point of time. Fourth, coordination of various color elements of other fields including landscape, interior, and electricity ensured construction of the whole structure in one color concept. Fifth, color inspection through the mock up of the site will minimize erroneous construction and reconstruction and prevent decrease in productivity. Sixth, this study also suggested more comfortable and positive color environment through evaluation by experts and users. The researcher of this study expects that color experts actively participate in the stage of construction to contribute to improvement of the color environment.

최근 건설공사는 초대형화로 단일 공사규모가 복잡해지고 천문학적인 공사비가 소요되는 프로그램 관리 형태의 성격을 지니는 사업이 등장하고 있다. 특히, 대규모 건설사업과 같이 프로그램 수준에서 관리가 절대적으로 필요한 사업은 계획된 일정 및 비용에 대한 전제적인 관리가 필요하다. 하지만 국내의 경우 구체적인 공사지연에 관한 관리기준이 부재한 현실이다. 이에 본 연구에서는 대규모, 장기간 진행되는 프로그램 수준의 대규모 건설사업을 성공적으로 수행하고 공정지연 및 부진사업을 사전에 방지하기 위한 지연관리지수(Delay Management Index, DMI)를 개발하였다. 이를 통해 대규모 복합건설 프로젝트를 대상으로 사례연구를 수행하였으며, 프로그램 수준 건설사업을 위한 지연예방체계를 구축하였다.
