The activity conducted throughout the life cycle of any facility generate an enormous quantity of data that needs to be stored, retrieved, communicated, and used by all parties involved. Advanced in technology have increased the opportunities for gathering, providing access to exchanging, and archiving all of this information for future reference. Considering that classification system of construction material is reviewed international exchange of information by the ISO standard, it is consist of classification form of construction process. As a result, this study analyzed to OmniClass Table-22(Master Format-20(4) for the purpose of gaining a the international standard and electronic information, and compared to OmniClass Table-23 ${\cdot}$ 35 ${\cdot}$ 41(UniClass, EPIC) for the expansion and standardization. Furthermore, it is tried to integrate with UN/SPSC attribute code for the establishing of application and international exchange.

The objective of this study is to improve the classification structure of commodity code for piping material management which is considered as the fundamental of commodity code and piping material management system. It enhances the efficiency of piping material management directly or indirectly affecting the engineering, procurement and construction in a petrochemical plant projects. To establish an improved code classification structure, this study identifies the problems of former code classification structure in details, as well as the characteristics of other domestic and global EPC company's code classification structures and presents the improved direction considering the recently mega-sized and specialized projects. Accordingly, to efficiently enhance piping material management, the improved code classification structures have been derived from defining suitable code classification structure for specific piping component, adding more standard attribute, expanding the number of code digits and classifying code hierarchy. The results of applying the improved classification structure of commodity code to on-going project have led to reduce the rate of rework from 4.98% to 2.48% for developing purchase description and also have saved working time for executing piping design by 3D modeling from 6 months by two persons to 4 months by a person which is decreased 67% consequently. In addition, the structures of pyramid code management have resulted to accumulation and analysis of the various piping data for other disciplines such as procurement and estimation team which require commodity code information through the company's material control system.

최근 건설 분야의 정보화 기술이 발달함에 따라 건설생애(Life Cycle) 과정에서 파생되는 방대한 양의 정보를 수집·가공·축적·제공 하는 시스템이 급증하는 추세이다. 특히, 건설공사의 주요요소인 자재 정보를 제공하는 Web 기반 온라인 시스템만 현재 110여개 이상으로 토목·건축·설비·소방 분야에 이르기까지 매우 다양하다. 그러나 이러한 시스템에서 제공 중인 정보가 표준화 및 정형화 되지 않아 건설현장 실무자들의 정보 획득에 있어 많은 어려움을 겪고 있다. 이에 본 연구에서는 정형화되고 표준화된 건설자재정보를 제공하기 위해 건설자재 분류체계를 정의하고 건설자재 속성정보를 정형화하여 자재별 분류체계검색, 통합검색, 카테고리검색 뿐만 아니라 전자카탈로그로 변환 및 생성이 가능한 건설자재정보 관리 시스템을 설계 및 구현 하였다.

As information technology of constructional area develops recently, web-based on-line system is rapidly increasing to provide information on diverse constructional materials so as to enhance productivity of constructional business and to reduce cost. Since the constructional materials information provided by these systems, i.e., quality, specification, etc are not standardized, however, the staffs on the constructional site suffer considerable difficulties in using materials information when acquiring information on specific materials, e.g., using diverse information systems or repeating similar jobs. Thus, this research typified information items of constructional materials on the basis of GDAS and designed multi system model to control integrated information on constructional materials. This system can efficiently control and utilize materials information by supporting automatic classification of constructional materials to which OmniClass Part-22 and UNSPSC are applied, conditional complex retrieval of materials information, real-time automatic embodiment of electronic catalog and retrieving/controlling RFID.

Standardization to information attribute of construction material is continuous demanded through the life cycle of a construction project, and the productivity elevation is derived of contribution effect in construction market. This study surveyed the means of acquisition and attribute of information to a staff in purchase, which are effected on the revitalization of information circulation to the construction material Proposed the standardization to information attribute of construction material that is based on improvement and application to the information attribute. And information attribute is classified with construction process through analysis on test list of quality certification. This study also suggested representative attribute of quality information, for the elevation of safety and quality in construction industry. Therefore, logicality of common information is based by analysis of mathematical statistics, systemicity of quality information is applied by MasterFormat(2004)

There have to be a pooled procurement in order to control construction in every stage. And we need also efficient supply chains to utilize the process. Researching and developing the method, which make it possible the supply chain management by modeling for Internet-enabled pooled procurement in construction, through breakdown in materials is currently in-progress the inside and out side of country. The objective of this paper is to find a reform while modeling the production process of cable duct moreover understanding the wasting factors in each step.

우리는 지식활동의 원천인 연구활동을 파악하기 위한 분류체계를 만들고자 하였다 그러나 지식활동분류와 관련된 이론체계가 정립된 것이 없어서 다양한 시가과 방법론을 검토한 후 이들을 체계화하며 새로운 방법론을 도출하였다. 이 논문은 바로 그 과정에서 이루어진 이론적인 작업을 정리한 것이다. 우리는 지식이라는 거대한 실체보다 새로운 지식을 추가하는 연구활동이 중요하다는 인식에 기반하였다. 또한 연구활동과 연구활동의 목적이 연계되고 학제연구라는 새로운 지적활동의 패턴이 자유자재로 반영되도록 하였다.

A material database has been developed for VOCs and formaldehyde emitted from building materials in this study. New classification system has been made by correlating the classification methods used in Korean Air Cleaning and Environmental Protection Agency. The developed databases include emission rates of TVOC, 5VOC and formaldehyde emitted from each building material. In addition, the databases can be used as an input variable to estimate indoor air quality (IAQ) using computer simulation since they also contain chemical component and general imformation. Box plot was used to do statistical analysis for emission rates of formaldehyde and TVOCs from different types of building materials. Also we confirmed the building materials worsening IAQ by categorizing the emission characteristic of different types of pollutants.

In construction industry, the cost related to material is different from each other under the characteristic of projects. However, it has 40% of the whole cost in the composition of prime cost. Recently, While the construction work become bigger, specialized and complex, it is complex to carry in materials because of shortage of space. However, in many cases, material management has been underestimated as well as the material management is depending on experience of site managers so it has been studied about frequently. In this study, I suggest four classification methods of material characteristic ETO, ATO, MTO, MTS. I also analyze what the most efficient supply management of the site materials is through researching the characteristics of the material distribution. In conclusion, I would like to build the material management classification for the characteristics of materials.
