In the 21st century, medical facility projects are required to operate appropriate digital technologies as the development of technology and the interests of various participants become more complex. In order for architects to successfully lead negotiations among various stakeholder groups, it is necessary to plan for effective communication through appropriate design reflecting their opinions and coordination of conflicts. For this purpose, building information modeling (BIM), which is a method of designing based on knowledge information related to medical facilities in the building database, can respond to change of order promptly and minimizes the occurrence of design errors can do. Recently, BIM technology and cloud computing technology in ICT have been combined and research on cloud BIM has been actively carried out. The use of cloud computing technology in BIM-based healthcare facility projects can effectively support decision making among project participants and has the advantage of sharing and collaborating on various forms of information generated during the design process, regardless of location and time.

Using BIM (Building Information Modeling)-based design information to analyze various engineering processes has been widely adopted in construction projects. However, since typical building permit processes often require traditional 2D-based design information for submission and to obtain building approval, there are some challenges in delivering such data thru BIM-based design information. This paper proposed a methodology to generate and meet information requirements for permit applications and approvals based on BIM-based design information. To that end, we analyzed the required information necessary to make submissions for building approvals using the Seumter system. We then suggested a process to collect the required information from BIM-based data, and classified this into two types: BIM-internal and BIM-external information requirements. In addition, we proposed three algorithms to extract and to match between extracted BIM data and BIM-internal information requirements using IFC(Industry Foundation Classes). The proposed methodology enables to ensure the efficiency and the accuracy when providing data for building permit review and approval.

Around the world, BIM application has been mandated. In Korea, an announcement was made in 2016 that BIM application will be required for all public constructions ordered by the Public Procurement Service. However, BIM cannot be used for building permits as Seumter, a building permit system, doesn't support BIM, even if it was used for building design. To utilize BIM for permit application, this study introduces a method of management for BIM-used permit application information. It was done by analyzing the data entered for new building permit application in Seumter. For the analysis, the permit application information is classified as internal BIM information and external BIM information and the required information is defined. To easily create and utilize the data types at the design stage, this study introduces a method of creating and utilizing a permit template. Also, this study developed a tool for combining the area information to add up all the related information such as gross floor area and floor area ratio. This study is significant in that it analyzes the required information for new building permit application among all the permit application types in Korea.

As the amount of information generated in the construction project increases exponentially, design and construction review have a serious impact on the success of the site. For this reason, academic and business circles have been expanding the use of BIM at the whole life, and BIM is now accepted as one of the standards used in the construction industry. However, the BIM-based design for the temporary work is used as an aid to the 2D design because there is no specialized software and there is absolutely lack of a professional engineer. The objective of this research is to develop BIM-based temporary work support system. This system minimizes human errors in BIM-based design, quantity takeoff and inspection and shortens working hours.

As the needs for the mega-sized, high-rise and irregular shape of building increase, domestic application of BIM in construction industry is increasing in recent years. In this circumstance, interests in BIM modeling and modeling detail level have been also increased. BIM that is based on a three-dimensions, requires a specific and precise building expressions. And model expression level required for each phase such as design, construction, and maintenance of the construction project could be different as its needs. Because that it is not clear to define the criteria for the expression level of construction BIM model, It is difficult to decide how detail and what to model is appropriate in the practical application of BIM model. It could be the reason why the productivity in construction project became lower and lower. In this study we consider the way how to improve the productivity of BIM and analyze the appropriate representation level of construction BIM model through the experts' survey. The results of study could suggest the basis for an appropriate expression level of construction BIM model.

BIM facilitates data transparency and consistency through three-dimensional parametric modeling and promotes the accurate managing and sharing of project information. In Korea, however, BIM-based detailed design of architectural interior finishes required during the Construction Documents phase increases the burden on architectural firms due to frequent design changes and manual workload. Therefore, the purpose of this study was to establish rule-based modules using parametric modeling that automates repetitive tasks that occur during the detailed design of interior finishing. Interviews with practitioners were conducted to analyze the major finishing elements. Of these floors, walls, and ceilings, which were the most rudimentary and common items, were selected as the subjects of the study. The modules developed in this study have two functions. One is to create new finish types, and the other is the automatic modeling of new types into rooms. For these functions, parameters that belonged to each finish and room element in a BIM model were analyzed and valid parameters directly used for parametric modeling were derived. Then, based on these parameters, rule-based modules for three elements, I.e., floors, walls, and ceilings were constructed with Revit Dynamo, and the effectiveness of the modules was verified with a pilot test. In conclusion, this study suggested a series of processes for automatic finishing to improve the efficiency of BIM-based architectural detailed design of finishes and to contribute in solving the chronic problems occuring during current design processes.
