Information sharing is the main purpose of realizing interoperability between the application domains of Geographic Information System (GIS) and Building Information Modeling (BIM). This paper presents and describes the workflow of BIM-GIS interoperability for highway traffic information sharing. An innovative and automatic Dynamo process was presented to transfer the shapes and attributes of the shapefile from GIS to BIM. On the basis of the transformed BIM model, the detailed traffic data was added and expressed in the form of families and sheets to expand traffic information. Then, the shapes of the model were swept as solid geometries in the BIM environment applying Dynamo. The expanded BIM model was transferred back to the GIS system using the Industry Foundation Classes (IFC) scheme. The mutual communication between BIM and GIS was achieved based on Dynamo and IFC. This paper provides a convenient and feasible way to realize BIM-GIS interoperability for highway traffic information sharing according to the characteristics of highways in terms of graphic expression and model creation.

최근 BEMS(Building Energy Management System)는 공간정보를 적극 활용하고 있다. 공간정보가 포함된 BIM(Building Information Modeling)을 잘 활용한다면, 사용자는 공간정보와 연계된 직관적 건물 에너지 관리가 가능하다. 이 연구는 BIM-BEMS 연계를 위한 MF(Model Filter)을 활용한 데이터 맵핑 방법인 M-BDL(MF-based BIM Data Linkage)제안한다. 최근 BEMS은 3차원 공간정보를 적극 활용하고 있다. 이를 통해 사용자는 공간정보가 연계된 직관적인 건물 에너지관리가 가능하다. BIM 데이터를 에너지 관리 시스템에 활용하기 위해서는, 사용자 요구사항 관점에서 필요한 BIM 데이터만 BEMS과 연계할 필요가 있다. 하지만, Rich dataset인 BIM을 그대로 연계한다면 사용자가 불필요한 정보까지 관리해야 하는 부담을 주게 된다. M-BDL을 통해, 무거운 BIM 데이터에서 BEMS에 필요한 데이터만 맵핑함으로써, BIM데이터를 경량화할 수 있었고, 유지보수에 필요한 데이터량을 줄일 수 있다. 이 기술은 필요한 BIM 데이터만 필터링된 BIM 데이터와 BEMS 데이터베이스 간 연계할 수 있는 M-BDL 맵핑 방법을 제안한다.

3D-based BIM(Building Information Modeling) technologies can be utilized effectively as a means of systematic management of facility information for safety assurance and effective maintenance of waterworks facilities. In this study, BIM models of water treatment facilities that can be used as basic data for BIM-based maintenance of waterworks facilities were developed. Information exchange and generality of the developed BIM models were evaluated by conducting interoperability analysis of IFC(Industry Foundation Classes) conversion models. In addition, the application of COBie(Construction Operations Building information exchange) was recommended as an effective countermeasure to deal with technical limitation regarding exchange and utilization of facilities-related information through current IFC models. The results of this study can contribute to the development of BIM-based maintenance system for waterworks facilities.

Advanced countries have mandated applying BIM in construction projects. Also, Public Procurement Service has planned to mandate applying BIM to all construction project that ordered in PPS from 2016 in KOREA. However, now Seumter that is building administration system is not supported BIM based construction license BIM information from Seumter. Thus, despite the applicant is preparing a BIM model, they do not take advantage of BIM information in Seumter. In previous studies. We developed a BIM based building approval submission system. In this study, we verified the system that developed in previous research. As a result, requirement information input time reduction in Seumter system showed high satisfaction. But there was as low usability because building approval submission system cannot support some information for building approval in seumter. If the system will do utilization and management with the building approval system, the applicant can be using BIM base design document information and saving the time that takes at building approval submission. Study about the system improvement is required for application to building approval system.

Since entering the 21st century, the construction industry has developed faster and faster, and more and more technologies have been applied in the construction industry. BIM technology (Building Information Modeling) was born in this environment. The application of BIM technology can greatly improve the efficiency of cost management and help achieve the goal of cost management. But through BIM to realize project cost management, there is still no good solution. In order to solve this problem, this paper puts forward the concept of WBS structure applied to construction projects by studying the BoQ (Bill of Quantities) list based on BIM, and proposes the numbering method of the structure. The WBS (Work Breakdown Structure) structure proposed in this paper divides more than 5000 cost objects into 133 projects according to the type of work and project schedule. This structure helps to realize the application of BIM in project cost management. Although this article has studied more than 5000 data of three projects, it does not think that it can cover all cost objects in the existing construction industry. The purpose of this article is to propose a solution for cost and Process Control using BIM-based BoQ data.

From the perspective of the client, the value of information for use in facility management is very low at the point of use. This is because the facility owner, who is a non-professional, cannot accurately request necessary information from the perspective of long-term facility life cycle management. The purpose of this study is to define the information necessary for facility management and to analyze the project operation method to procur this information to the client using BIM. To this end, this study analyzed the role of client and contractor, project delivery process, standards, and submissions in the BIM-based procurement area through USACE Air Force Hospital project case analysis. As a result of the analysis, if the client, who is the subject of facility operation, defines in advance the type and input method of necessary information in the operation stage, the client can receive the BIM optimized for operation from the contractor. The results of this study can be used to establish standards for receiving information necessary for establishment of procurement process and facility management of public institutions considering BIM introduction.

The importance of efficient construction site management has been growing as the amount of construction information increases which is used in the growing construction site. Accordingly in this study, we are trying to find out the application situation and possibility of BIM through theoretical examination and domestic & overseas case study of BIM and we are trying to suggest the way of efficient construction site management formulation through implementation phase-oriented and cooperation entity-oriented analysis in the construction site. We found out that it was possible to minimize time loss and financial loss by visualizing 2D drawings through 3D modeling of target building by applying BIM and that it was possible to improve accuracy of budget planning with quantitative information of 3D model, to plan construction process with more confidence due to accurate architectural information of drawings and quantitative information, and to manage cost and quality through process management based on construction information acquired by BIM including object information by part. It is concluded that we can improve efficiency of construction management between field and each cooperating entity by integrating and linking BIM information through this process.
