우리나라에서 건설산업의 구조개편, 건설기술의 경쟁력 향상 등과 맞물려 CM에 대한 다양한 논의과정이 있었으며 건설산업기본법('97) 및 건설기술관리법('01)에 CM제도가 규정됨으로써 명실상부하게 체계를 갖추게 되었다. 이 중 특히 공공사업에 대해서는 효율성 제고라는 문제의식에서 출발하여 제도의 활성화를 위한 시범사업(Pilot Project)이 정부를 중심으로 추진중에 있다. 현재 추진중인 시범사업은 제도의 정착, 활성화 뿐만아니라 기존의 CM제도를 좀더 구체화하고 다양화하는 과정으로서 그 시행의 중요성을 인식할 수 있을 것이다. 이러한 시범사업의 추진을 통하여 현재의 감리중심의 CM제도에서 발주자 및 사업특성을 고려할 수 있도록 Owner형 CM, PM형, 민자사업 적용방안 등 다양한 CM적용형태를 모색해야 할 것이다. 이러한 노력들은 공공사업의 효율성 제고 뿐만아니라 민간부분에도 많은 영향을 미칠 것으로 기대된다.

PURPOSES : Efficiency Improvement of a public road construction project management work using the development of a real-time remote site monitoring system METHODS : In this study, we developed the remote site monitoring system using a web camera for road construction projects in the RCMA(Regional Construction Management Administration). We can be monitored a construction progress and a weak point of the situation in real time using this. To achieve this, we tested about 10 road construction projects ordered by RCMA. Then, we verified a applicability for the site monitoring system in future. RESULTS : Take advantage of the remote site monitoring system consists of the Construction CALS System, one of the business systems used in the part of the MLTM(Ministry of Land, Transport and Maritime Affairs) institution-agencies. Was configured to be served through the "Construction CALS System" of "Construction Management System(Contractors)" and the "Construction CALS Portal System". Through this, Benefit analysis through a pilot application of the 10 road construction sites and developing considerations and "Guide for visual information processing equipment installation-operating in construction sites"are presented. CONCLUSIONS : Through the establishment of remote site monitoring system can improve the efficiency of construction management services. In addition, Various disasters and calamities, accidents and illegal construction will be prevented in advance is expected. This is expected to further improve the quality of the facilities.

Recently, Korean government demands that public sectors like railway construction should improve their management efficiency. It is necessary for railway construction supported by government budget to aim at the companywide management efficiency. The Balanced Scorecard (BSC) is known as integrated performance management framework that helps a company to translate strategic objective info relevant performance within an organization. This paper focuses on relationship between KPIs (Key Performance Indicators) used to measure the performance of railway construction industry and process KPT for BPM (Business Process Management). Also, the vision and strategies of the railway construction is introduced, and the CSFs (Critical Success Factors) and the KPI based on BSC is developed. Finally, this paper explores that there is a possibility to fulfill the strategic objectives of railway construction industry through the connectivity between KPI based on BSC and process KPI based on BPM. We explain the detailed procedures with an example of railway construction industry.

Recently, research on digital twins to generate digital information and manage construction in real-time using advanced technology is being conducted actively. However, in the construction industry, it is difficult to optimize and apply digital technology in real-time due to the nature of the construction industry in which information is constantly fluctuating. In addition, inaccurate information on the topography of construction projects is a major challenge for earthmoving processes. In order to ultimately improve the cost-effectiveness of construction projects, both construction quality and productivity should be addressed through efficient construction information management in large-scale earthworks projects. Therefore, in this study, a 3D digital map-based AR site management work support system for higher efficiency and accuracy of site management was proposed by using unmanned aerial vehicles (UAV) in wide earthworks construction sites to generate point cloud data, building a 3D digital map through acquisition and analysis of on-site sensor-based information, and performing the visualization with AR at the site By utilizing the 3D digital map-based AR site management work support system proposed in this study, information is able to be provided quickly to field managers to enable an intuitive understanding of field conditions and immediate work processing, thereby reducing field management sluggishness and limitations of traditional information exchange systems. It is expected to contribute to the improvement of productivity by overcoming factors that decrease productivity in the construction industry and the improvement of work efficiency at construction sites.

The connection system of steel pile and RC footing is an important structure, because the total load of upper construction should be transferred through this joint construction of different two materials-steel and RC-with strongly changed section area. Although many connection systems have been developed, their structural and economical efficiency and workability are often insufficient. Therefore, a new connecting system was developed to improve the problems of current systems. The divided arc plate could improve the workability and economical efficiency, structural efficiency could be reached by welding construction. The main purpose of the research is to evaluate the structural behavior of the new designed connection system through experiments and numerical analysis.

The purpose of this study is to develop a method of evaluating eco-efficiency of concrete based on environmental load emission, manufacturing cost, and durability in the concrete production process. Eco-efficiency is an advanced concept used to evaluate eco-friendliness of concrete. This technique intends to produce environment-friendly and highly durable concrete while minimizing environmental load on the ecosystem and manufacturing cost based on the results of service life assessment on concrete. This technique can be utilized to efficiently evaluate sustainability of concrete and find methods to improve it. Furthermore, the vision of this study is to contribute to implementation of environment-friendly concrete and construction industry.

Environmental issues become one of today's central concerns due to draining natural resources and environmental pollution. Architecture is given a great deal of weight on the evoking environmental pollution. In this point of view, polluting factors in architectural planning and construction were predicted in advance and alternative plans were studied, In investigation of alternative plans, both environmental pollution and economical efficiency of various alternatives were considered. A office building was analyzed for energy consumption and construction environmental load by appling LCA. Applying LCA to a office building includes a total amount of materials and energy consumption, environmental impacts and economical efficiency evaluation. In present study, LCA applied to electrical part of a office building and economical efficiency evaluation was considered.

Procurement and lifting scheduling of modules and resources in modular construction, where modules that are manufactured from factory are delivered and assembled on site, is a crucial factor that determines the efficiency of the whole construction. However, previous studies have barely acknowledged the significance of resource procurement process and lifting of modules in modular construction. Therefore, this research aims to derive factors that are in need of improvement for successful implementation of procurement and lifting efficiency, and visualize them according to their importance and performance on improvement through IPA(Important Performance Analysis).
