The purpose of this study is to propose a modeling methodology through the exchange of coordinate data of a three-dimensional custom curtain wall panel between Rhino and Revit, and to examine the validity of the model implemented in the drawing. Although the modeling means and method are different, a fundamental principle is that all three-dimensional modeling begins by defining the position of the points, the most primitive element of geometry, in the XYZ coordinate space. For the BIM modeling methodology proposal based on this geometry basic concept, the functions and characteristics associated with the points of Rhino and Revit programs are identified, and then BIM implementation process model is organized and systemized through the setting of the interoperability process algorithm. The BIM implementation process model proposed in this study is (1) Modeling and panelizing surface into individual panels using Rhino and Grasshopper; (2) Extraction of vertex coordinate data from individual panels and create CSV file; (3) Curtain wall modeling through Adaptive Component Family in Revit and (4) Automatic creation of Revit curtain wall panels through API. The proposed process model is expected to help reduce design errors and improve component and construction quality by automatically converting general elements into architectural meaningful information, automating a set of processes that build them into BIM data, and enabling consistent and integrated design management.

The BIM libraries and technical contents in order to develop common technical standards that reflect the contents for a BIM design support should be based. It is essential to redress the technological burden on design office requirements. The technical contents consisted of Material Information, Standard Details and Cost Information are made by system of standard classification. By connecting BIM libraries with each of information including the contents, it derives the consistent BIM data application through the integrated model. In addition, we look forward to introducing and applying BIM more easily through securing common technical contents which remove the pressure of engineering developments of each individual architectural design office and prevent overlapping investments.

The purpose of this study is to propose an curriculum for architectural studio in university to implement BIM process, through the analysis of the advantages of the BIM tool. The limitation of this study was to analyze the case study of only half year a single university. University education in the design process, the design that can be used in applying BIM content should be universal, university education considering the special working conditions, excessive BIM-based application can be difficult. Therefore, a systematic and reliable design that can be applied to education applies BIM design process is necessary to establish. University education applying BIM design review and design proposal the various 3D visualization can be used effectively to determine. In addition, the planned representation for thinking about and drawing 3D model building, architectural space can be used for visualization, and other subjects in conjunction with structural analysis, environmental analysis, facility layout, etc. can be used.

The maintenance management in buildings has got more important by the increasing complexity of building sizes and use. Nowadays an expectation and a possibility of BIM technology become accepted as a new construction management method, therefore many studies and legal systems of it are being suggested actively. Although orders for BIM projects are supposed to be increasing, at present the BIM information accumulated from planning and design still doesn't have its continuity at the maintenance step after completion of construction in terms of LCC. It can't use the possibility that BIM originally has, and also causes some confusion in communication. This study analyzes and classifies required information in terms of BIM in the range of estimating repair costs of apartment buildings, as an example of a way to use BIM information at the maintenance step.

The Building Information Model (BIM) is gaining wide popularity in the construction industry. This attempt is, however, limited to a predefined operation of structural facilities. The application of BIM can be extended to include undefined operations in earthwork construction. The objective of this paper is to introduce the concept of an earthwork BIM environment that is currently under development in the Construction System Laboratory at Pusan National University. First, this paper defines the concept of earthwork BIM. Second, it discusses the key aspects of earthwork BIM, including 1) geographical information, 2) equipment configuration, and 3) equipment position. In the future, the 3D BIM environment will be tested at an actual construction site to determine its applicability, and it will be extended to include construction equipment such as bull dozers and pay loaders.

The usage of Building Information Modelling (BIM) in building projects has enabled improvement in project planning, implementation and collaboration process amongst various stakeholders within architecture, engineering and construction (AEC) industry. However, variations exist in the current practices of BIM implementation and coordination process in the industry. These variations result in inconsistent degree of BIM use across the construction industry. This inconsistency gives rise to several managerial and technological challenges such as data interoperability issues and purposeful integration and exchange of information within the BIM components. In order to tackle the issue, it is essential to analyse the different BIM approaches employed by the industry practitioners. BIM guidelines serve as a critical link between the BIM model, and its subsequent execution. They therefore provide the best reflection of BIM application and processes. This research paper aims to address the variations existing in BIM practices across the construction industry. It includes an extensive study of 21 existing, publicly available BIM-based guidelines in order to establish an understanding of the present state of practice and deduce issues and concerns related to them. All guidelines analysed in this paper are first categorised based on authorship and the release date for efficient comparison. The points of similarity and difference between them are thereby realized and outlined. In addition, the transition of project implementation process from traditional methods to BIM technology is also explained. The existence of inconsistencies in the BIM guidelines reviewed in this paper reflects the need of a BIM 'Code Compliance Check'. The Code Compliance Check will serve as a regulatory project guideline that will further improve the potential of BIM by incorporating a consistent BIM modelling methodology for the entire construction industry.

Recently BIM technology has been expanded for using in construction project. Due to the high-cost of BIM infrastructure development, lack of regulations, lack of process and so forth, usage of BIM has been delayed than initial expectations. In design phase, especially, collaboration based on BIM system has been a key factor for successful next generation building project. Through the analysis of current research trends about IT technologies, virtualization and BIM service, data exchange such as drawings, 3D model, object data, properties using cloud computing and virtual server system is defined as a most successful solution. The purpose of this study is to enable the cloud computing BIM server to provide several main functions such as editing models, 3D model viewing and checking, mark-up and snapshot in high-performance quality by proper design of VDI system. Concurrent client connection performance is a main technical index of VDI. Through testing of test-bed server client, developed VDI system's multi-connect control is evaluated. Performance-test result of BIM server VDI effect to development direction of cloud computing BIM service for commercialization.

최근 건설업계에서는 3D객체기반인 Building Information Modelling(이하 BIM)에 대해 관심이 증가하기 시작했다. 하지만 BIM도입에 어려움을 격고 있는 것이 현실이며 특히 전통적인 정보교환 방식에서의 BIM을 적용하는데 가장 큰 어려움을 격고 있다. 현재 국내에 활용되는 전자도면 표준지침에는 BIM도입에 필요한 2D표준에 대한 내용은 없으며, BIM소프트웨어들도 이 부분에 대해서 충분히 커스터마이징 되지 않았다. 이는 BIM과도기에 2D도면의 필요성을 인식한다면 원할한 BIM도입을 위해서 반드시 그 대안이 필요하다. 따라서 본 논문에서는 국내 BIM 도입 시 국내 2D 전자도면표준을 고려한 BIM 모델에서의 원할한 2D도면추출에 대해 Template을 활용하는 방안을 제안하였다. 도면표준의 기준은 "건설CALS/EC 전자도면 작성 표준"에 근거 하여 표현기준 및 데이터 작성기준을 Template파일에 적용 시켰으며, 이 후 실험을 통해 BIM 도입 시 효율적인 도면 생산의 가능성을 확인 하였다.
