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.

현재 우리나라의 건설공사 설계기준은 총 50종(설계기준 21종, 시공기준 29종)으로 관리부서가 통합되어 있지 않아 여러 가지 문제점이 발생하고 있다. 그 문제점으로 설계기준 간에 내용이 중복 또는 상이하여 사용상의 불편함이 있다. 현재 사용자가 직접 설계서를 작성 시 산재된 관련 기준을 일일이 확인하여야 하는 번거로움이 발생하고 있다. 또한, 건설기준 정비체계가 미흡하며 국외의 설계기준을 실 검증과정 없이 도입하여 우리나라 특성에 맞는 건설공사 설계기준이 반영되지 못하는 경우가 생기고 있다. 본 연구에서는 하천 댐 설계기준 및 하천 표준시방서를 관련 있는 타 분야 설계기준 및 시방서(설계기준 5종, 시방서 7종)와 상충 및 중복되는 항목을 조사, 비교하였다. 그리고 조사, 비교된 내용들을 수정 및 보완하여 '건설공사 설계 시공기준 표준화' 기획단계시 기준간의 통일성, 편의성을 고려하여 구성된 코드체계기준 중 수자원분야 표준코드체계 기준에 적용하였다.

본 연구과제는 건설업체의 현재 문제점은 각 업체별로 상이한 분류 및 식별코드체계를 사용, 품목표기방식, 속성 포맷의 불일치, 용어와 단위의 불일치, 현 업계에서 사용하는 코드 분류체계는 호환이 되지 않고 국제적으로 사용할 수 없는 부적합한 실정이다. 따라 기존의 통합정보시스템과 별개로 관리 운영이 이원화되어 오던 각종 건설정보를 건설CALS/EC 핵심기술을 적용하며 건설표준 ERP 템플릿시스템을 개발 할 목적으로 한다. 따라서 본 연구에서는 건설표준 ERP 템플릿시스템과 건설통합분류체계의 표준코드의 연계로 건설CALS/EC 핵심기술이 적용된 건설표준ERP(통합DB)를 구축과 건설공사의 물량산출 데이터의 체계화된 물량예측과 물량공정의 통합화와 설계정보, 시공정보 및 관리유지정보의 연계하여 그리고 현장관리 및 원가관리정보의 통신망접속으로 건설통합정보를 제공한다.

Project Informations Classification System (PICS) can be utilized as a springboard for advanced construction management techniques because it marries informations to networks and maintains a disciplined cost control. The present study attempts to develop a PICS which can be applied in construction management techniques. The frame work largely consists of the three parts such as: (i) development of the tentative Work Breakdown Structure with three divisions, facility calssifications, functional classifications and work classifications, covering the whole areas of civil works, (ii) development of the integrated informations system including the other informations in cost estimating and network scheduling, (iii) construction of relational database system for computer application. The system suggested in the study is found useful for the systematic and uniform management of construction works in the various stages.

With the rise of BIM application and green building assessment, studies on assessment of CO₂ emissions from buildings using BIM are needed. In accordance with the requirements, this study aims at developing BIM Template database, as a part of development of CO₂ assessment technology using BIM. Based on the research of construction materials, this study develops database by applying Procurement Agency Item Code to BIM Template. The results of this research makes it possible to assess CO₂ emissions of materials with BIM Template and building data modeling implementation.

Recently, in Korea, a few construction companies have been tried to develop a management system, which is able to integrate schedule and cost. In spite of these attempts, however, advanced management techniques can be hardly applied under the BoQ based management system. In order to improve these problems, many studies have been peformed, but yet could not overcome practical limitations. Besides, the application of historical data is below the level since it is so difficult to accumulate and feed-back historical data under the unique character of construction industry. Consequently, lots of time and effort have being wasted to establish control criteria. The newly generated Information is not systematically managed as well. Therefore, this study suggests Integrated Construction Management System complemented the existing practical problems.

This paper designs and proposes a file conversion process to IFC file, the international standard file format for BIM, in order to ensure mutual compatability and manageability among users of commercial BIM modeling and design softwares in the civil engineering area. The proposed process insert additional properties consisting of the properties of quantity calculation codes and properties of CBS/OBS/WBS standard classification scheme, to the three dimensional object shape information of the converted IFC files, using add-in converters for commercial BIM modeling softwares. In addition, a process of integrated use of IFC files for open web-based quantity, process(4D), and construction cost(5D) management is additionally designed and implemented. Based on these works, the ultimate goal of this study is to propose a novel process for integrated use of open web-based quantity, process(4D), and construction cost(5D), from the design stage of BIM modeling to the final construction stage in the civil engineering area.

In case of applying the BIM method in the civil engineering of irregularly shaped structure, BIM method began to be introduced in the current building engineering area compared with the expected effects of the relatively high construction productivity has been recognized. In this paper, I have developed quantity calculation algorithms applying it to earthwork and bridge construction, tunnel construction, retaining wall construction, culvert construction and implemented BIM based 3D-BIM Modeling quantity calculation. Structure work in which errors occurred in range between -6.28% ~ 5.17%. Especially, understanding of the problem and improvement of the existing 2D-CAD based of quantity calculation through rock type quantity calculation error in range of -14.36% ~ 13.07% of earthwork quantity calculation. It's benefit and applicability of BIM method in civil engineering. In addition, routine method for quantity of earthwork has the same error tolerance negligible for that of structure work. But, rock type's quantity calculated as the error appears significantly to the reliability of 2D-based volume calculation shows that the problem could be. Through the estimating quantity of earthwork based 3D-BIM, proposed method has better reliability than routine method. BIM, as well as the design, construction, maintenance levels of information when you consider the benefits of integration, the introduction of BIM design in civil engineering and the possibility of applying for the effectiveness was confirmed. In addition, as the beginning phase of information integration, quantity document automation program has been developed for activation of BIM. And automatically enter the program code number, linkage and manual volume calculation program, quantity document automation programs, such as the development is now underway, and step-by-step procedures and methods are presented.

The purpose of this study is to develope BIM Template according to major building material for efficiently and quantitatively evaluating greenhouse gas emission at the design stage. Template users consider various environmental impacts without connecting simulation tools for analyzing environmental impact and Template users who have no prior knowledge can Life Cycle Assessment by using The green template. For this study, Database which was reflected in template was constructed considering environmental performance. and 6 kinds of environmental impact categories and PPS standard construction codes were analyzed by major building material derived from literature. Based on this analyzed data, The major Material Family according to the main building material was developed. When users conduct modeling by utilizing Family established, evaluating result can be confirmed in the Revit BIM Modeling program by using the schedule function of the Revit. Users through the modeling, the decision-making environment performance possible. In addition, we propose to create a guideline for the steps required to build an additional established family.
