Construction industry becomes large and complicated as that occurred in the construction processes and operations, and the growing social demand for more systematic and efficient methods of integrated management increases. Current facility maintenance system has been regarded as large labor-intensive and fairly stagnant, and faced on several issues including inefficiency in cost and time to collect and utilize various field information. Thus, this paper presents a maintenance prototype utilizing NFC technology and smart devices to efficiently collect and manage the field information in the course of the construction processes. By choosing dam facilities as a case study, construction data for dam inspection and maintenance were classified according to dam maintenance guideline, and database structure was constructed to incorporate with the NFC tags and smart device interface. The system prototype presented in this paper would improve the quality of the dam facilities maintenance system and provide business convenience and usability by contributing increased efficiency of field information management and sharing.

본 논문에서는 최근에 개발되어 지하철 919공구에 적용된 BIM 기반 통합 공사관리 시스템의 구축방법과 적용성에 대해 검토하였다. 최근 대형 국책사업이 발주, 시공되면서 효율적인 공사관리를 위한 PMIS 도입이 보다 활발해지고 있는 가운데, 기존의 텍스트와 그래프 위주에서 BIM(Building Information Modeling) 기법의 하나인 4D, 5D 시스템을 이용한 다양한 시도가 되고 있다. 한편, BIM은 건설 전 생애주기에 걸쳐 활용되어야 그 도입목적을 극대화할수 있으나, 현 단계에서는 계획 및 설계단계에만 초점이 맞춰져 있어 실제 공사중에는 그 활용도가 상당히 낮은 수준이었다. BIM 기반의 통합 공사관리 시스템은 공사중, 현장과 본사를 비롯해 발주처와 감리단 등 다수의 공사 주체들이 계획, 설계시 구축된 BIM을 보다 효과적으로 사용하도록 함으로써, BIM의 공사중 활용성을 높일 뿐 아니라 유지관리 단계까지 확장하여 이용될 수 있다. 본 논문에서는 BIM 기반 통합 공사관리 시스템을 구축하기 위한 절차를 살펴보고, 최종 구축된 통합시스템의 적용성 분석후 활용방안을 제시하였다.

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.

Recent years, the construction projects of a world-wide have changed toward integrated evaluation considering all environmental and economic aspect for ecological construction.. The object of this study is to suggest the method and system for integrated analysis VE/LCC and LCA. In order to integrate and analyze environmental and economic aspects of alternative design elements, decision maker should handle simultaneously much information such as cost, document and drawing. This study presents applicative methods of WBS for integrated management of these information. Also, this study presents a decision support system that can manage DB easily by using VE, LCC and LCA analysis module separately.

Current construction project processes pose difficulties for construction management as inefficient communication between project participants seldom accurately reflects the needs of the owner. To solve this problem, lean construction-based Integrated Project Delivery (IPD), which facilitates cooperation and builds trust through the formation of horizontal relationships among participants, is becoming increasingly popular. However, although lean construction-based IPD improves productivity in the construction industry, few studies have focused specifically on developing effective methods that maximize the benefits gained from lean construction-based IPD. This study therefore analyzed success factors for lean construction-based IPD projects by analyzing prior studies to identify factors that support IPD success. Application methods were analyzed and an example of how they are actually used in the field was examined through an in-depth single case analysis. The findings of this research can be applied to support lean construction-based IPD projects in Korea, improving their efficiency and boosting owner satisfaction.

Almost 40 years have been passed since the CPM was introduced to the construction industry in Korea. However most of construction projects in Korea do not prepare the CPM schedule neither operate it after established manually, as well as still depend on the Bar-chart schedule only. One of these reasons is because the CPM schedule does not reflect the site works realistically, it makes so difficult to recognize the actual progress clearly in visual format, and it is impossible to integrate and manage the time and cost oriented work progresses effectively. This paper proposes new concept of progress management that is able to integrate and manage the time oriented schedule progress and earned value oriented cost progress while maintaining the merits of CPM although the CPM schedule summarized automatically within a schedule hierarchy by the BDM that is a new CPM technique. We expect that this concept could make the applications of CPM technique to the domestic construction industry popular and help the advancement of the construction management in Korea as well.

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.
