In the current 2D-based design, design reliability is lowered due to interference and inconsistency between plans, errors in drawings and quantities, etc. At the time of transition to BIM-based 3D design, it is necessary to expand the reliability and usability of BIM by eliminating these errors from the design stage through securing the quality of the BIM digital model. Therefore, in the railway infrastructure design stage, the quality management process and standards of the BIM digital model were defined and quality management index were developed. Based on the rule extracted from the quality management index, a pilot quality management was conducted in connection with the commercial Model-Checker rule, problems and improvement plans were derived, and a rule-based automated quality management plan was prepared.

최근 공공사업 발주조건에 BIM(Building Information Modeling)이 의무화되고 있고, 실무 도입을 통한 성공 사례가 증가되면서 건설 분야의 BIM 도입이 본격화되고 있다. 그러나 기존의 BIM 관련 연구는 대부분 설계 또는 시공단계에 한정되어 수행됨에 따라 건설프로젝트의 생애주기를 고려하지 못하고 있고, 특정 업무지원 기능 위주로 진행되고 있다. 따라서 본 연구에서는 건설공사 프로젝트의 기획부터 유지관리단계의 생애주기 동안 단계별 BIM 적용이 가능한 통합 BIM 운영 프로세스를 제안하고 이를 토대로 통합 BIM 시스템을 개발한다. 이를 위해 교량공사를 대상으로 수행단계별 정보체계를 분석하여 BIM 활용 기능과 적용 프로세스를 제시하였으며, 이에 근거하여 수행단계별 BIM 운영 시스템을 구축하였다. 연구에서는 개발된 시스템의 실무 적합성 검증을 위해서 사례적용과 건설 실무자의 활용성 설문 조사를 수행하였다. 이러한 BIM 통합 운영체계는 생애주기를 고려한 건설공사의 3차원 기반 통합정보관리체계로 활용성이 기대된다.

The architecture, engineering and construction (AEC) industry is beginning to utilize Building Information Modeling (BIM), benefiting from the resulting improved visualization and productivity, better coordination of construction drawings, building documents that contain embedded links to virtual information, faster delivery, and lower costs. However, construction firms often face challenges when reorganizing their company structure to take full advantage of these benefits. This paper proposes an organizational structure that will enable engineering-construction firms to successfully adopt and implement BIM for major construction projects. A case study research method is utilized based on in-depth interviews with four BIM directors and vice presidents charged with BIM adoption, implementation and education. Organizational transformation challenges and recommendations are discussed in detail for those considering implementing BIM in the engineering-construction industry. Topics such as organizational changes in the firm, costs and benefits of BIM implementation, strategies of BIM implementation (execution) plan, BIM education, risks and opportunities associated with BIM, BIM software, contract methods, human resource management and new hires, and the future implementation and direction of BIM are discussed in detail.

토공사는 타공종에 비하여 건설공사에서 차지하는 비용 및 공사기간의 비중이 높다. 이에 따라 토공사는 건설공사의 생산성에 높은 영향을 미치게 되는데, 종래의 토공사 시스템에서는 숙련된 굴삭조종자의 휴리스틱스에 의한 토공사 계획 및 토공작업을 수행하는 노동집약적 프로세스를 고수하고 있어 생산성을 높이기 힘든 상황이다. 이러한 당면과제를 극복하고자 본 논문에서는 BIM 기반의 지능형 굴삭시스템을 소개하며 굴삭 작업 계획 생성 시스템, 원격조종 및 자율 굴삭 작업에 필수적인 Human-Machine Interface(HMI), 웹기반 Project Management Information System(PMIS)이 개발되는 과정에서 적용된 BIM 요소기술에 대하여 검토하고, 적용된 결과를 제시하고자 한다.

BIM has been a reliable construction project management tool to handle various kinds of construction information generated in the facility life cycle. To take these advantages, researchers have been promoted numerous studies in a residential, a commercial, and an educational facilities with a large number of on-going projects. However, despite running as the role of essential energy supplier, power plant related BIM research is relatively insufficient than others. In particular, due to the extending of the facility service period and the requirement of the complicated construction project management for 'overhaul' and 'repowering' in the power plant maintenance phase, the needs for using BIM have been increased gradually. For using BIM based maintenance, it is needed to consider an information collecting methods and necessary to develop an appropriate breakdown structure to share information. Therefore, 'EBS' is produced by reviewing the previous research related to BIM and analyzing the repair activities in the maintenance phase. Proposed 'EBS' must be useful not only a judgment between capital expenditure versus revenue expenditure but also appropriate maintenance strategies development for property management.

Quantity take-off (QT) is one of the most important tasks for determining the total cost of a construction project, and it requires accuracy and reliability for the result. Accuracy and reliability in BIM-based QT are also required to assure the completeness of the result. However, there has been no basis to measure the completeness of the BIM-based QT result. As BIM is increasingly being adopted in the construction industry with a wide variety of purposes, it becomes more important to have a method to improve the completeness of BIM-based QT and criteria to measure it. This research focuses on the hypothesis that the completeness of BIM-based QT relies on the accuracy and reliability of BIM and the BIM-based QT process. As a basic research to determine the completeness of BIM-based QT, this research analyzes and derives factors that affect the completeness of BIM-based QT.
