It seems obvious that the spatial information of existing architectural heritage will be re-structured utilizing BIM technology. In the future to be able to implement such task, a new system of classification of spatial information, which fit to the structural nature of architectural heritage is necessary. This paper intend to suggest the conceptual model that can be the base of establishing new classification system for architectural heritage. For this study we reviewed researches related to classification system of architectural heritage (CS-AH) and BIM based architectural heritage (BIM-AH), first. As a result, we found that CS-AH is focused on building elevation and type, and BIM-AH is biased on the Library and Parametric Modeling. Second, we figured out a relationship between the CS-AH and BIM-AH. From this analysis, we found that BIM-AH is biased on Library and Parametric since the building elevation and type was focused on CS-AH. This review suggests a potential of the 3D CS-AH to expand the range of research for BIM-AH. At last, we suggest the three concept of classification are: 1)horizontality-accumulation relationship, 2)structure-infill relationship, 3)segment-member relationship. These three concept, together as one system of classification, could provide useful framework of new classification system of spatial information for architectural heritage.

BIM based design methodology requires more information than traditional design methodology in order to insure efficiency throughout the project. BIM based design not only requires all building data in the form of 3D shapes, but also all other relevant data regarding building components. Information is typically grouped in a standard classification system such as by standardized material names. The development of a domestic BIM based standard classification system is yet to be created and deployed in the industry. Each designer is specifying their own building information classification systems which is causing inconsistency in the industry. Therefore BIM based designs, are causing confusion in the industry as each designer follow no guidelines for material standardization classification. The lack of information regarding this in the BIM template will continue to cause confusion about a projects building information data consistently. This study is that of preliminary research to develop a BIM template. First, overseas BIM templates were analyzed regarding BIM standards and documentation. Examination then followed regarding the element and characteristics needed for the development of a BIM template, a suggested hierarchy of elements required for a BIM template were then made. The result of this research is that it will be used to develop a "BIM template prototype", to support the generation of building information data regarding neighborhood facilities.

In this study, we have developed a calculation system for BIM-based quantities, 4D process, and 5D construction costs, by integrating object shape attributes and the standard classification system which consist of Cost Breakdown System(CBS), Object Breakdown System(OBS) and Work Breakdown System(WBS) in order to use for the 4 dimensional process control of roads and rivers. First, a new BIM library database connected with the BIM library shape objects was built according to the CBS/OBS/WBS standard classification system of the civil engineering field, and a integrated database system of BIM-based quantities, process(4D), and construction costs(5D) for roads and rivers was constructed. Nextly, the process classification system and the cost classification system were automatically disassembled to the BIM objects consisting of the Revit-family style elements. Finally, we added functions for automatically generating four dimensional activities and generating a automatic cost statement according to the combination of WBS and CBS classification system The ultimate goal of this study was to extend the integrated quantities, process(4D), and construction costs(5D) system for new roads and rivers, enabling the integrated use of process(4D) and construction costs(5D) in the design and construction stage, based on the tasks described above.

With the recent development of 4th industrial revolution technology, BIM information systems are spreading to civil engineering fields as a link to this technology. Accordingly, the Land, Infrastructure and Transport Ministry is announcing a technical policy to introduce the BIM information system into the construction sector from 2020. Usually, SOC-related facilities are complex, making it difficult to implement BIM without a standards framework. To overcome these problems, it is urgent to develop a BIM standard classification system. In this study, the BIM property classification system was developed to link the previously developed object classification system by analyzing domestic and foreign prior studies and working standards. This includes property information of businesses, facilities, parts of facilities and components that correspond to the level of object composition in the road and river sectors. It also suggested ways to apply expansion to various SOC areas and to organize spatial information by facility. The results of this study were applied to road facilities to verify the possibility of information building. The development of the BIM Standards Classification System through this R&D will contribute to the development of construction IT by providing conditions for convenient modeling and information system.

Standardized construction information classification enables extensive information from the construction industry to be shared and exchanged clearly by means of unified information expression. Recently, the constriction information classification in North America and Europe has been revised to adapt to BIM technology and applied to various BIM projects. In Korea, government established construction information classification and made efforts to be standardized. On the other hand, it showed low applicability at the practice field and had no revision plan for adapting BIM. In this study, the authors suggest an improvement plan of construction information classification for applying BIM with the purpose of availability enhancement and adaption to a construction environment change.

Recently, BIM is used at several areas actively because of introduction of BIM in the construction industry. In particular, the recent many studies on activation of BIM information sharing is underway and it is the future direction of BIM. Moreover, it should be clearly realized. In the BIM levels of domestic construction phase, Interference Review, calculating volume estimates in part based on the active research is underway. However, still interested in reviewing building codes have relatively little interest. As BIM enabled, The methods of reviewing building codes should be transformed into a automated system by using information of BIM. In overseas, they are already using diverse softwares for reviewing modeling. Thus, For an automatic review of building regulations research is needed. this study is research on the development Domestic building codes as an automatic review process by using BIM. In order to Automatic review of the current building regulations by using BIM, this study analyzes the characteristics of each piece of information.

Building Information Modeling (BIM) tools have not only increased the use of technology in the design process, but also increased the need for more information standard systems. The object classification system consists of 327 types of construction results obtained from 25 kinds of facilities, 174 types of parts, and 207 types of construction parts. In the previous study, the property classification system was developed into 4 major classifications, 13 middle classifications, 58 small classifications (category), and 333 attribution information of roads and rivers. It is extremely difficult to input the property information according to such extensive object classification. In addition, the development of external applications such as Revit plug-ins has created a need to automate specific and repetitive tasks. Therefore, following the BIM property classification system, an attribute input program was implemented for the system to enhance the productivity and convenience of the BIM users.

In the case of river facilities, the management of this information differs depending on national and regional rivers, therefore, there is no integrated management in place. There is concern about the loss of facility information owing to the insufficient accumulation of information during their design and construction stages. Additionally, as a result, the utilization level of facility information during the maintenance and operation stages is insufficient. To ensure effective maintenance and operation of river facilities, it is necessary to secure data consistency and increase efficiency by organizing facility information according to a standardized classification system. This study proposes a strategy for implementing the BIM standard classification system in the river sector, considering facility characteristics. The goal is to introduce a BIM information model for 3D-based river facilities, and enable efficient maintenance and operation conversion.
