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.

Plant, civil engineering and construction equipment data of overseas construction are obtained and then analyzed, classified and integrated by experts. With those refined data set, we built classification system and defined property information with reference to international standard (ISO 15926, IRDL). If class in ISO 15926 is predefined for equipment of interest, we used the class as is. If not, we created and defined new classes on the basis of ISO 15926 classes. If there is similar class for equipment of interest, extension or inheritance methods were used. As a result, classification system of five levels and 637 classes were built and construction equipment information were expressed in open structure of XML such as tree structure of classification system and detailed information with number equipments for each specific equipment. We also developed the electronic catalog system which is basically equipment information management system providing various product search functions.

Recently, extensive research has been conducted on classification systems for managing a huge amount of information with various froms in the construction industry. Classification Systems such as ISO/DIS 12006-2 and MasterFormathave been proposed as international standards, and accommodating them for Korean situation the Korean Ministry of Construction and Transportation has proposed the Unified Construction Information Classification System. As the construction industry becomes bigger and more complicated, however, the need for higher-level semantic representation of construction information has been recognized. In this study we develop a prototype ontology based upon the Unified Construction Information Classification and suggest a practical way of applying an ontology technology to the construction information systems. An ontology is a useful tool to effectively manageconstruction information and to support interoperability among heterogeneous information systems by clarifying the semantic relationship between concepts.

This paper presents a fundamental study to establish a standardization system of the Construction Continuous Acquisition and Life-cycle Support(CALS). States of standardization in the Construction CALS were reviewed to find some defects in developing CALS system in construction industry. It is analyzed that three of major parts were needed to put up a standardization system for the Construction CALS. Firstly, the range of Construction CALS standardization is set up by identifying of Construction CALS and defining the standard and standardization. Secondly, the strategy to enable more effective implementation of Construction CALS standardization and the relationship of the concerned system presented can be used for establishing the Construction CALS standardization system. In addition, the spread and application device is proposed for using Construction CALS standards at public institutions and construction related companies. Conclusively, a classification system of the Construction CALS standards was proposed and some objects to be standardized were presented in the classification system. What were studied in this paper will provide the primary information and guidance to develop a guideline for standardization of the Construction CALS.

As information technologies in construction field get developed, various studies and projects are in progress for improvement of construction industry. Meanwhile, web-basis online system for building materials is tending upward. However, most of the informations about classification system for building materials and specifications are not systematic yet. Most field staffs have some troubles in making full use of the material information, repeating inefficient works from constructional design to the maintenance of it. This study designed auto-categorization system classified by materials, multi-search engines, auto-converting/creating electronic catalog as well as RFID search support to provide standardized building materials information.

Considering that the classified items in the work section level can have an applicability when those items are being used to cost and specification information with consistency, the work section classification code should be applied as an Integrated code system. Our construction industry is using three work section classification systems for civil engineering projects, such as integrated construction information classification system, standard method of measurement and guide of project specification. And each standard construction specification is also using different work section classification systems. This study suggests a methodology to integrate the code systems in construction specifications with civil engineering standard method of measurement. And the methodology suggested in this study was applied to a web-based prototype system with practical specification codes.

The construction industry has a structure in which information asymmetry problems are complexly scattered compared to other industries. Since the construction industry classification system serves as a guideline for entering the construction market and can provide as a standard for construction consumers to select a supplier who can provide appropriate services, when judging the operation purpose or purpose of the construction industry registration system, it is very important to set up the system by rationally reviewing it. The purpose of this study is to examine the possibility of improvement in consideration of the risk factors related to the domestic construction industry registration industry classification system. To this end, we will conduct a case study on the construction industry classification system operated by overseas construction industry licenses or registration systems in Japan, the United States, and Australia, and compare it with the domestic industry classification system to derive implications and directions for improvement.

Our government suggested an integrated construction information classification system (CICS) for improving construction information exchange between project participants. However, because a database for integrating construction documents and drawings is insufficiently built, there are many restrictions in using CICS. Therefore, this study suggests a methodology to integrate and manage the construction documents and drawings by CICS. The methodology suggested in the study is verified to a web-based construction documents and drawings management system with integrated DB.
