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.

정부에서는 2001년 5월에 실무적용을 위한 ${\lceil}$건설정보분류체계 구축을 위한 연구${\rfloor}$ 를 추진하여 대${\cdot}$중분류 등을 제시하였고, 그 결과 '통합건설정보분류체계 적용기준'을 건설교통부 공고로 2001년 8월에 발표하였다. 그러나 구축된 '통합건설정보분류체계'는 건설공사에서 실무활용이 미흡한실정이다. 일반적인 시설물과는 다르게 교육시설물의 경우 적용기준이 혼재되어있는 문제가 이다. 더욱이 2005년부터 교육시설물에 BTL 민간투자 사업이 시행되면서 유지관리시업무기준이나 비용계상에 대한 기준을 '통합건설정보분류체계 적용기준'에 적용할 경우 경계를 명확하게 하기 어려운 실정이다. 따라서 본 연구는 기존의 유지관리 비용분석으로 사용되었던 공종(Work)중심의 시설물 유지관리를 분석하고 이를 보완하기위해 공간(Space), 부위(Element)중심 유지관리 분석을 하여, 효율적인 유지관리 체계정립을 위한 분류의 기준을 제안하였다.

The Taiwan government agencies have been promoting e-commerce for the construction industry with several initiatives since 2000. The development of standards for the procurement information exchange among government agencies, construction firms, and suppliers for the construction industry is one of the major initiatives and begins to produce tangible results. This paper reviews the effort for developing the information exchange standards and compares the development strategies used in different segments in the supply chain. Lessons learned during the development course are also discussed.

The Standard for BIM in Construction of China was released in 2017. The Unified Standard for BIM of China also took effects on 2017. The BIM standards of China needs to be compared with those related guidelines of Korea to find the status and characteristics for future development of BIM application in both countries' construction industries. The research methodology is a case study of comparing various standards of both countries. The case study results reveals many interesting issues for future BIM application and guidelines for practice of design and construction process. The research foundings include followings : LOD (Level of development) are well defined including LOD 350 in Chinese Standard. P-BIM(Practice based BIM) concepts and series of standards are set for the well-defined design and construction process by work stage in China. Korean standards shows more processes of design and documentation in detail. Major three aspects, particularity in BIM standard by work trade, practicality in BIM work process of design and construction, and professionality in subjects of BIM application, are analyzed and compared with various Guidelines of BIM in both countries.

General technique and management technology of agriculture have development in every year to ensure the competitiveness of agriculture. Accordingly, Interested in using information systems management technology is improving. For information system, the first system of rural buildings category should be established. Classification system is set up through each specific code. and it takes advantage of the information system is to achieve the computerization of agricultural society. Therefore, in this study construction information classification system, quantity of output category, got to the standard classification system architecture, apply to agricultural buildings to review the situation and saw a problem. The result, it is the complexity and broad scope, and it is set to inappropriate setting of the Category item.

본 연구는 조경공사 표준품셈의 개정 작업이 진행되고 있는 현시점에서 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘의 식재 공종의 내용의 특성을 비교하여, 향후 한국의 조경공사 표준품셈의 발전에 기여하는데 연구의 초점을 두고 진행하였다. 표준품셈과 표준보괘의 특성을 파악하기 위해서 한국의 경우는 2010년 '국토해양부'에서 제정한 건설공사 표준품셈 공종내의 조경공사를 연구 대상으로 하였다. 또한 일본의 경우도 2010년 '국토교통성' 제정 토목공사 표준보괘의 공원식재공사 표준보괘를 연구대상으로 하였다. 그리고 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘 공종 중에서 식재 공종에 초점을 두고 품셈의 범위, 세부 공종, 품셈의 구성, 수목 적용 규격, 품셈의 내용 등의 비교를 연구의 내용적 범위로 한정하였다. 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘의 식재 공종의 내용을 비교하여본 결과, 한국의 조경공사 표준품셈은 독립적인 품셈과 품셈의 적용에 있어 융통성이 필요하다. 그리고 지주목에 대한 독립적인 품셈과 운반에 관한 품셈 규정 그리고 조경토와 관련된 품셈 등의 검토를 통하여 한국의 조경공사 표준품셈이 더욱 발전할 수 있다고 판단된다.

The Standard penetration test determines the type of soil according to soil bearing capacity, and this classifies the subsoil into many layers. Construction project managers are willing to know the depth of the present types of subsoil on site in order to make plans on earthwork stage during excavation. However the standard penetration test may not provide accurate information on subsoil type due to incorrect spacing. To solve this problem, this study propose a conceptual algorithm for determining the spacing of standard penetration test spots to essentially tests relevant locations on which to be applied the standard penetration test. This provides the acquirement of the accurate layered model volume of earthwork revised into geological columnar section. This algorithm will determine the appropriate standard penetration test spots spacing on a given size of site to optimize the accuracy of the earthwork volume, time and cost.

In the situation where there should be a gap between the design environments of 2D drawing and 3D BIM modeling, it is unavoidable aspect to face confusion caused by parallel usage of both technologies unless the project delivery systems are entirely upgraded to 3D. Therefore, it is critical to make efforts to minimize this confusion. Meanwhile, detailed drawings have very important roles in the construction process because they do not only concretely express construction methods for a given design plan but also provide basis for quantity takeoff and construction cost estimation etc. This paper suggests a plan to standardize detailed information based on BIM standard framework in order to make BIM realize the information. In the short term, this plan provides improved environment where both BIM and CAD technologies can be applied and, in the long term, it provides bases for BIM to replace CAD technology.

The domestic process planning generally relies on calculations based on the construction-standard-production-rate. This method requires trial and error practice during the construction phase to deduce the optimized equipment combination for time and cost. Trial and error during construction can lead to cost overruns and schedule delays. Accordingly, this paper suggests an advanced method for establishing a productivity database based on combinations of equipment and also considering site conditions in order to reduce the timely effort for deducing the optimized equipment combination. For this purpose DES (Discrete Event Simulation) model was developed based on the information provided in the construction-standard-production-rate.
