BIM(Building Information Modeling)은 건설 프로젝트의 생애주기 동안 발생되는 정보의 호환성 및 재활용을 중심으로, 분절된 산업 구조에서 생성되는 정보의 불확실성, 부정확성, 표현 오류 및 표현에 대한 인식 오류 등을 최소화하기 위해 도입이 모색되고 있으며, 이로 인해 기존의 PMIS 시스템은 새로운 기회이자 기술적 도전에 직면하게 되었다. 하지만 기존의 BIM에 관한 연구는 기획/구조/설비/견적/설계/시공 시뮬레이션 등 분야별 BIM 기반 솔루션 개발 또는 IFC 중심의 정보 호환성 체계 구축에 초점을 맞추고 있을 뿐, 건설 프로젝트의 쳐업 및 정보 관리를 효과적으로 지원하기에는 한계를 가지고 있어, 새로운 개발전략 및 방안이 요구되고 있다. 따라서 본 연구에서는 기존 ASP기반 PMIS를 중심으로 BIM+PMIS 시스템의 구축 방안을 제안하고, 제안된 구축 방안 중 핵심이 되는 BIM 기반 정보 관리 모듈에 관한 프로토타입을 소개하고자 한다.

The railway project is an essential green transportation tool that is considered suitable for the domestic and foreign policy direction of carbon neutrality, but there are some limitations, such as damaging important carbon absorption sources during construction. This study analyzed the environmental impact assessment related to carbon absorption sources of greenhouse gas evaluation items conducted during the railway project, and limitations and implications were derived. The analysis of environmental impact assessment guidelines related to railway projects and carbon absorption sources dealt with prediction and reduction methods related to carbon absorption sources, but guidelines, including environmentally friendly railway construction guidelines, lacked descriptions. Since the greenhouse gas environmental impact assessment, 83 railway project environmental impact assessments have been reviewed, but in some cases, carbon absorption-related predictions have not been implemented, or carbon absorption-related reduction measures have been insufficient. In addition, there were cases where there was a limit to calculating emissions and reduction or where the reduction value was insignificant compared to emissions. In order to supplement the environmental impact assessment in the field of carbon absorption sources related to railway construction projects, alternatives such as quantitative emission and low reduction calculation, review of the no net loss system using the total environmental resource system, and linkage with climate change impact assessment are needed.

Recently domestic youth unemployment rate has increased continuously. The cause is due to construction recession. As a result, the youth unemployment rate was approximately 8.0% in 2013. In particular, graduates of civil engineers and architecture engineers are difficult to find a new job. Major construction companies also prefer new employees rather than career employees. Therefore, the employment rate of construction-related university graduates is continuing decline. Accordingly, construction and technical engineers will be aging. Therefore, this study was looking for ways to promote the overseas expansion of young construction engineers. And this research has suggested the ways which young engineers can find a new job through improving the system.

A number of documents containing important and useful knowledge have been generated over time in the construction industry. Such text-based knowledge plays an important role in the construction industry for decision-making and business strategy development by being used as best practice for upcoming projects, delivering lessons learned for better risk management and project control. Thus, practical and usable knowledge creation from construction documents is necessary to improve business efficiency. This study proposes a knowledge creating system from construction documents using text mining and the design comprises three main steps - text mining preprocessing, weight calculation of each term, and visualization. A system prototype was developed as a pilot study of the system design. This study is significant because it validates a knowledge creating system design based on text mining and visualization functionality through the developed system prototype. Automated visualization was found to significantly reduce unnecessary time consumption and energy for processing existing data and reading a range of documents to get to their core, and helped the system to provide an insight into the construction industry.

Safety of workers and productivity in construction site are affected according to the conflict status of work spaces which are performed at a time. The interference among the work spaces in construction site should be minimized because it becomes a blocking factor that causes construction delay and low productivity. Those factors can be managed by reasonable H&S (Health & Safety) practice. This research suggests the requirements of H&S practice and rules to establish the strategy of H&S management based on the literature reviews related to H&S rule. The suggested H&S rule can be visualized for searching space conflict point if the rule is linked with visual simulation tool. Accordingly the research results can be used for improving and visualizing construction productivity by work space control in 4D/nD CAD system.

Construction industry still requires a lot of laborers to perform a project despite of advance in technologies, and improving labor productivity is an important strategy for successful project management. Since repetitive construction works exhibits learning effect, understanding laborers' learning phenomenon therefore allows managers to have improved labor productivity. In this context, previous research efforts quantified individual laborer's learning effect, though numerous construction works are performed in group. In other words, previous research about labor learning assumed that sum of individual's productivity is same as group productivity. Also, managers in construction sites need understanding about group learning behavior for dealing with labor performance problem. To address these issues, the authors investigate what variables affect laborers' group level learning process and develop conceptual model as a basic tool of productivity estimation regarding group learning. Based on the result of this research, it is possible to understand forming mechanism of learning within the group level. Further, this research may contribute to maximizing laborers' productivity in construction sites.
