Compare to other industrial sites, the civil construction work not only takes longer time but also has made of complicated processes, such as the integrated management, process control, and quality control until the completion. However, it is hard to take control the construction sites, since numerous issues are always emerged. The study purposes on providing the dataset to synthetically manage and monitor the civil construction site, main design, drawings, process, construction cost, and others at real-time by using the low altitude close-range aerial images, based on UAV, and the GPS surveying method for treating the three-dimensional spatial information quickly and accurately. As a result, we could provide the latest information for the quick decision-making following from planning to completion of the construction, and objective site evaluation by the high-resolution three-dimensional spatial information and drawings. Also, the present map, longitudinal map, and cross sectional view are developed to provide various datasets rapidly, such as earthwork volume table, specifications, and transition of ground level.

건설사업의 원가절감은 사용자 요구에 부합되는 기능과 품질을 확보하면서 가장 경제적인 방법으로 시설물을 구축하는 것으로 건설환경 변화에 따른 경쟁력 향상을 위해서는 체계적인 원가관리를 통한 원가절감이 필요하다. 국토교통부 소속 산하기관에서는 공공건설사업의 수행에 따라 설계의 경제성 등 검토, 공정관리 및 사업관리 등을 통해 공사비 절감에 대한 많은 노력을 기울이고 있다. 현재 설계단계에서 설계VE 결과정보는 공공발주기관 간에 상호 공유하고 있으나, 시공단계에서의 원가절감사례 정보에 대한 공유는 아직까지 부족한 실정이다. 공공건설사업의 수행시 유사 건설사업에 대한 원가절감사례 정보를 참조 활용할 수 있도록 단계별 정보시스템 구축 및 원가절감 사례 정보서비스 방안을 제시하였다. 향후 공공건설사업의 기획, 설계, 시공, 유지관리 등 생애주기별 원가절감사례 정보의 분석 및 서비스를 통해 보다 합리적인 의사결정과 공공건설사업의 투자 효율성을 제고할 수 있으리라 기대된다.

Becoming construction projects larger and more complicated, and utilizing more varied and complex contracting and delivery systems in the industry, integrating information and managing constructability from project inception to completion became the most critical tasks for the successful project management. However, current industry practices of constructability analysis which are too much dependent on field engineers and managers' experiences, are not performed efficiently and also not managed effectively. Then the scope, method, and procedure in performing analysis tasks are not certain as well as not systematic, In addition, due to using 2D based drawings and documents, information required at project phases for the analysis is inconsistent and inaccurate. This study aims to suggest the use of BIM technology and functions for solving various problems of current constructability practices. In particular, constructability analysis tasks performed at design and construction stages are identified and their adaptability, applicability, and benefits of BIM are investigated through interviews on constructability and BIM professionals in the industry.

Most engineering tasks require collaboration between many users in major hospital construction projects that have many reconstructions. Loss and change orders occurred in factors such as information exchange, misunderstandings, advanced technology in hospital projects. Moreover, changes in context, costs, requirements, deadlines, etc. require negotiation of issues that may modify important project characteristics. The objective of this paper is to reduce reconstruction for the pre-construction process of hospital projects, reconstruction factors were analyzed in recent hospital construction project the system was established in order to solve reconstruction factors, and this system was validated through applying to the real project. Therefore it is a major challenge to make high level of communication and to have mutual understanding.
