건설프로젝트의 대형화, 복잡화, 다양화로 인해 전략적 대응방안 중 하나로 BIM(Building Information Modeling)이 등장하였다. 최근 조달청에서는 2012년부터 500억 이상의 건설 프로젝트에 BIM적용을 의무화하는 BIM 활성화 계획을 발표하여 국내 건설 산업 전반으로 BIM도입이 확산되고 있다. 이에 BIM기반 프로젝트 사례를 바탕으로 각종 BIM연구가 진행되고 있다. 그러나 현재 BIM관련 연구는 BIM도입에 대한 단편적인 문제점 도출 및 BIM에 대한 기술력과 체제 구축 등의 문제점을 중점으로 활발히 진행되고 있으나, 본질적인 BIM기반 프로젝트 전반에 대한 만족도에 관한 연구는 전무하다. 따라서 본 연구는 국내 BIM기반 프로젝트에 대한 실태 파악 및 만족도를 조사하여 이를 종합적으로 분석하고 현재 실무자들의 시각에서의 프로젝트 내 BIM적용에 대한 중요 부문 및 취약 부문을 파악한 뒤 중점 개선하는 방향을 제시하는 등 효율성 면에서의 BIM기반 프로젝트에 대한 만족도 연구를 하였다.

This paper introduces recent applications of three-dimensional building/construction data modeling (3D) and building information modeling (BIM) to large-scale complex building construction projects in Japan. Recently, BIM has been utilized as a tool in construction process innovation through planning, design, engineering, procurement and construction to establish a front-loading-type design building system. Firstly, the background and introduction processes of 3D and BIM are described to clarify their purposes and scopes of applications. Secondly, 3D and BIM applications for typical large-scale complex building construction projects to improve planning and management efficiency in building construction are presented. Finally, future directions and further research issues with 3D and BIM applications are proposed.

Considering its significant impact on the cost and schedule of construction projects, formwork as one part of temporary facility categories in construction should be arranged precisely. Current practice in the formwork planning is often conducted manually and repetitively, causing low efficiency and time waste. This study proposes an automated framework to generate more accurate and detailed formwork plans by utilizing information from building information modeling (BIM) considering the adequate geometric and semantic information provided by the BIM model. The dimensions and quantities information of elements in a building can be extracted automatically. Then, a rule is prepared for calculating the required forms erected around elements based on the contact areas. Finally, an algorithm of integrating first fit decreasing (FFD) with coordinated bottom left (CBL) is applied to automatically generate the formwork plan. The BIM-based automated planning framework is demonstrated by an illustrative example. The results show that the proposed framework can generate the formwork plan accurately and automatically, and significantly improve the efficiency in the formwork plan and reuse.

The Eco-performance assessment program was developed as part of Eco-performance management for buildings at the national level in developed countries. Cases of domestic Green Building Certification(GBC) system was developed but these program's destination of Eco-performance management for buildings needs systematic management by the limited GBC. Generally in the construction industry, Eco-performance management of Building Life-cycle is required. Therefore this paper develop the creation of Eco-performance information and management process, those are from design and maintenance management phases, through suggest the development of a information management for Eco-performance management of buildings. In addition, it makes to decrease the reproduction of information unnecessarily by analyzation of the related association between the information of facilities objects and Eco-performance management. Finally, study the previous reaserch and suggest the BIM by the method of information management and this paper purpose the development of web-based Eco BIM object library management system.

Domestic construction industry suffered from the IMF and makes a great effort to improve in 'cost management', 'strengthening the competitiveness of the construction industry'. Therefore, the industry has become interested in improving the productivity of construction and ongoing research is being progressed in various angles. In such circumstances, the needs for a study of concepts and space of the actual construction work place is emerging. This study were utilized BIM to understand the types and causes of problems in space during the finishing work in construction and categorize importance and frequency of occurence through a survey of experts and AHP to analyze the realtive effects of importance then modeling to them to aware of issues and give direction for efficient management. This study is anylize the problem which is caused by same time process in finishing work progress of apartment applied by BIM. and categorize the type of work interference management in finishing work, and anylize by the type of occurence then predict the work interference management through in BIM 3D VIEW and suggest the solutions.

건설프로젝트에서 발생하는 정보의 양이 방대해짐에 따라 프로젝트 관리에 있어서 정보시스템의 역할이 점점 커지고 있다. 최근 건설프로젝트관리를 위한 효율적 의사결정 지원도구인 PMIS (건설사업관리정보시스템)가 다양한 프로젝트에 적용되고 있으나 그 활용정도가 저조한 실정이때 보다 효율적으로 프로젝트를 관리할 수 있는 시스템 개발이 요구되고 있다. 건설정보화의 발전단계 측면에서 살펴보면 2D 기반에서 3D 기반으로, 최근에는 BIM 기술로 발전되어 가고 있으며 BIM기술을 접목한 PMIS의 개발이 연구대상으로 부상하고 있다. 본 연구에서는 BIM 기술기반의 PMIS 개발을 위한 Pilot Test 모델을 제시하고 그 활용성을 검토하기 위한 프로세스를 제시하여 향후 BIM 기반의 PMIS 발전방향을 모색하고자 한다.

In South Korea, there have been attempts to enhance BIM work practices in various aspects. Public Procurement Service(PPS) has recently published 'basic guidelines to improve BIM work practices in construction and facility management'. It defines roles and responsibilities of project members in their application of BIM. It also developed a set of modelling standards and guidelines for effective model creation, management and communication among BIM users. Moreover, numerous construction companies have tried to cultivate BIM specialized manpower throughout entire construction phases. However, there are still challenges faced by firms during BIM adoption. Therefore, this study aims to provide practical counsel for construction companies to help them create optimized facilities and deliver high performance by analyzing BIM-based domestic construction projects in Korea from 2009 and 2015. The study will investigate types of client, project, BIM application range, and application technology.

Building Information Modeling (BIM) is being widely spread in AEC industry worldwide and also in South Korea. Although the creation of digital model is better to be started at design stage, it can also improve the productivity of construction by simulating the actual construction process and environment. This paper presents application of BIM-based simulations related with design changes to transfer floors in 58-storey reinforced concrete office building. Transfer floor is not only a structurally important part of the building but also a challenging part of the actual construction in terms of sequence and period due to the complexity of the work. Preconstruction of rebar, mechanical, and plumbing is performed to review the construction drawings and to perform clash detection. Each item of application is evaluated for its effectiveness on actual construction and for the development potential.

Domestic and foreign software components are rapidly developing continuously. However, the government's plan to activate BIM remains relatively sluggish. In particular, BIM based information management systems have been developed to enable the development of degraded railway industries in infrastructure BIM based areas. For this purpose, we analyzed domestic and oversea policies and guidelines. We conducted a survey on the personnel of the railroad corporation. Based on the survey result, the elements applicable to BIM were reflected in the system.

Building Information Modeling(BIM)기술을 유지관리 단계에서 활용하기 위해서는 상당량의 유지관리 데이터와 BIM기반 정보모델 객체들이 연계되어 운용되어야 한다. 본 연구에서는 교량 점검데이터를 표현하기 위해 확장된 IFC기반의 BIM모델과 온톨로지를 연계하여 정보를 관리하는 방법을 제시하였다. 이를 위해 현재의 IFC버전은 교량 객체를 제대로 표현할 수 없기 때문에 교량을 위한 IFC엔티티를 확장하였으며, 확장된 IFC기반의 정보모델을 생성하는 방법을 제시하였다. 또한, 교량 점검데이터에 대한 기본 개념을 추출하고, 교량 점검데이터를 위한 온톨로지(Ontology)를 생성하였다. 추출된 기본 개념들은 제시된 온톨로지에서 시멘틱 웹의 트리플(Triple) 방식으로 관계를 형성되었다. 마지막으로, 생성된 IFC기반의 BIM모델은 제시된 온톨로지와의 통합을 위하여 시멘틱 데이터 형식으로 변환되었다. 확장된 IFC기반 BIM모델은 제시된 교량 점검데이터 관리를 위한 온톨로지와 통합되었고, 실제 교량 점검데이터를 기반으로 테스트모델을 생성하였다. SPARQL query를 통해 목적에 맞는 교량 점검데이터가 추출됨을 확인하여 실효성을 검증하였다.
