Recently, BIM (Building Information Modeling) technique is being considered as a critical delivery condition for the public projects according to the increase of best practices by practical application of BIM. However, since existing BIM studies are focused on the design and construction phases, those results are not considering the life cycle of a construction project. Therefore, this study suggests an integrated BIM operation process that enables an application of BIM for each phase of a construction project from planning to maintenance phases and develops an integrated BIM system based on the suggested methodologies. This study developed basic BIM functions and its application process by analyzing information systems in each project phase for a bridge construction project. Besides, this study performed case study and survey analysis for construction managers to verify a practical applicability of the developed system. Therefore, it is expected that the integrated BIM system is going to be utilized as a 3D-based integrated information management system considering life cycle of construction projects.

In recent years, building information modeling (BIM) has been an important issue within the architect, engineering, and construction (AEC) industry. BIM provides a way to share and exchange semantically rich information about the buildings in order to achieve a successful level of collaboration, communication, and interaction between stakeholders throughout the life cycle of the project. However, despite the recognition of its potential, BIM has not yet been utilized in the construction, operation, and maintenance stages because of the need to reorganize the BIM by reflecting the as-built status of the buildings. In order to improve and increase the use of BIM at all phases of a project, several research efforts are exploring the creation of an as-built BIM that is based on advanced sensors. However, there is a lack of literature and investigation on this research area to date within the domestic AEC industry. The aim of this study is to suggest ways in which BIM can be utilized within the construction, operation, and maintenance stages based on advanced sensors so that it is an approach that might be usefully carried forward. This paper begins by presenting a review of the existing BIM research and achievement in order to determine the limitations of the use of BIM in the domestic AEC industry. Conclusively, this paper suggests a direction for the future applications of BIM and describes how it can benefit from additional research.

Recently, construction projects have become bigger and complicated and the construction business scale has enlarged. Therefore a project cost size is increasing. The historical data can be easily saved by advanced technologies of IT industries. Utilizing those make us to be able to manage construction project more effectively. These days, PMIS (Project Management Information System) has supplied widely at construction companies for integrating cooperation system of Web environment. and it is being used. However the most PMIS is limited at construction phase. Actually it isn't applied to a construction project Life-Cycle(planning, design, construction and maintenance). To control manage a construction project Life-Cycle effectively, BPMS (BIM-based PMIS Modeling) should be considered. This paper suggests the ways for applying BPMS.

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.

This paper discusses on implementation methods for providing data exchange capability of the Construction Project Lifecycle Management System (CPLM). Because most information media currently used in the construction industry are computer files, the system must be capable of handling various file types; however, The goals of PLM cannot be achieved if the contents of the files are communicated freely, which can only be achieved using a standardized information model that has comprehensive coverage of all information produced within the projects (i.e., a BlM). Several methods of adopting the model are investigated here, and a transitional implementation method for K-IFC is suggested, in which a file-based exchange backed by the BlM can evolve into object-level transactions of the BIM with not only advanced data integrity and security, but also improved communications between the project participants.

Recently, Korean Traditional House is being reconsidered as a alternative and eco-friendly residential housing. With these flows, government and industry actively studies the modernization and industrialization of Korean Traditional House. Apply for BIM as a way of modernization and industrialization of Korean Traditional House, research has been actively conducted. Korean Traditional House is building that is assembled by individual Component Therefore it is very useful for modernization of the Korean Traditional House to design Korean Traditional House With BIM. Which is the management technology that produces and distributes information of the architecture. But compared with the effect, the use of BIM is sluggish in the construction. Therefore, In this study after surveying about lowly using BIM on point of AEC(Architect-Engineer-Contract), the result is analyzed with AHP(Analytic Hierarchy Process). So the aim of this study is to offer the base to find the solution of the Affecting factors about lowly using BIM.

The Architecture, engineering, & construction (AEC) industry domains have grown more complex and larger, BIM is a digital representation of a building to facilitate the exchange and development of construction information integration and interoperability. Industry Foundation Classes (IFCs), under development by International Alliance for Interoperability (IAI), represent the part of buildings or elements of a process. IFC has been adopted as a central information repository in order to deliver integrated building information. Other BIM software could open the IFC file, recognize standard objects such as walls, window, and doors as building components. The IFC standard is generally agreed to be of high quality and is widely implemented in software. However, sometimes, information distortion or information toss occurrs during information exchang. The IAI Model Support Group (IAI-MSG) offers the opportunity to certify IFC-compliant applications based on a structuralized approach. However, IFC interoperability error also have occurred by using certificated tools. As project participants exchange BIM information by using BIM software they will need a reliable and efficient exchange of information. In this paper, previous interoperability tests were analyzed, and we propose a new concept in interoperability test.

BIM has been increasingly deployed to the construction industry in order to minimize ambiguity and to reduce errors of the communicated engineering information, for which poor communication due to fragmented industrial structure is mainly responsible. Known BIM use cases and related researches are focusing either (1) on a specialized solution for a given specialty area (e.g. structural engineering planning and early design, material take-off, constructability simulation, etc.), or (2) on handling interoperabillty issues with Industrial Foundation Classes (IFC); Neither of these approaches have sufficiently catered for collaboration and information management in actual construction projects. This paper proposes the strategy for BIM+PMIS (project management information system) system focused on improving PMIS which has been commercially provided with ASP(Application Service Provider). It also describes the architecture of the BIM-based information management module prototype, which is a key component of the BIM+PMIS system.

As construction project has been becoming larger, specialized and complicated, it is important to utilize a lot of information that is made by diverse participants. Especially this information is mainly produced in construction site that plays a leading role in construction project. The problem of information exchange between participants of construction site causes decline of construction productivity. So as to resolve this problem, there is a many interest in BIM(Building Information Modeling) that makes and manages a necessary data during building life cycle. But in Korea construction industry, applying BIM in construction phase is less active than in design phase. Through studying previous research, this study classify the main cause of failure related to information exchange in framework construction. And by interviewing expert, it draw a work that is possible to apply BIM. Next through analyzing framework construction site that is applied with BIM, this study proposes specific information flow model for supporting work by BIM.
