Korea's construction engineering companies are facing difficulties in deterioration of international construction profitability because they focus on traditional engineering fields such as design and construction supervision. Therefore, it is necessary to strengthen competency of high-add-value engineering field such as Project-Management-Consultancy (PMC). This paper aims to suggest the strategies to enhance the international PMC competency. This study identified the competency factors for international PMC, using Borich needs assessment and Locus for focus model. As a result, step-by-step strategies were suggested according to the competency level in domestic engineering companies. The results of this study will assist Korean engineering companies to consider the important competencies for international PMC projects. Furthermore, enhancement strategies are going to be proper references for domestic engineering companies which prepare the international PMC project.

The provision of spatial data is a key infrastructural requirement for the promotion of economic growth, environmental quality, social progress, etc. 4S technology integrates 4 kinds of systems that process spatial data: GIS (Geographic Information System), GNSS (Global Navigation Satellite System), ITS (Intelligent Transport System), and SIIS (Spatial Imagery Information System). Spatial data processing field is expected to get synergy effect and overcomes development limit of individual unit technology via 4S technology. This paper discusses both the development of 4S-kernel technology and the construction of 4S-based framework, In the development of 4S kernel technology, we will concentrate on the following issues: the development of 4S base components for reciprocity integration among GIS, SIIS, GNSS and ITS technologies, the development of 4S-Mobile S/W and H/W, 4S-Van components, and national LBS technologies. And in the construction of 4S-based framework, we will especially concentrate on the ISP for overall 4S technologies, the international cooperative research center, and the guide model deduction for supervision and certification of 4S projects. Finally, we examine about how the construction of 4S-baed framework affects 4S industry.

As the supervision in site is integrated into construction management, the organization's work is expanded, and the perspective and goals of the work have changed, so there is a high possibility that the conflict situation within the organization will increase. Organization conflict increase a job stress of workers, so it acts as a negative factor in deriving organizational performance. Therefore, the purpose of this study is to analyze the correlation between organization conflict and job stress of construction manager in construction site. As a result of the study, the organization conflict of the construction manager was generally low, and the job stress was also less than that of other area's workers. In addition, correlation analysis revealed that organization conflict and job stress were related. The results of this study may help to improve the organization structure in the construction management site organization.

Digital documentation is now becoming a must throughout a building process including design, construction, inspection, procurement and even facility management. The Internet is a backbone of such process, and web-based information exchange is the standard among other mainstream technologies. The current information management techniques, however, is heavily dependant on the server-side processing, which naturally results in the overload of the overall system. This paper proposes an XML-based approach in order to resolve such problems. A VE system was developed to demonstrate the efficiency of the XML solution, in term of efficient VE data management and fast decision making. also in this paper suggests 1) introduce XML based DBMS to improve data management efficiency and 2) introduce Mobile Computing to improve data accessibilities on sites.

Performance measurement and evaluation is a critical issue in public funded civil infrastructure projects in recent years. As a results, Korean government has introduced the related policies and regulations based on the foreign cases to evaluate public construction projects. However, construction circumstances are different from other countries and the results from adopted regulations are not satisfied. Therefore this research proposes the critical success factors(schedule, cost, productivity, change order, safety, quality) for public construction projects based on previous related research outputs to successfully implement construction performance evaluation. Then, this paper also proposes the weights for the critical success factors. The proposed weights are developed by AHP of construction experts. Furthermore, the paper shows the difference of the weights of the critical success factors by project participants (owner, constructor, engineering, and inspector). This efforts will enhance the ability to develop an effective performance evaluation process and system for public construction projects.

Demolition work is a precedence activity that is performed earlier than other remodeling activities. And demolition work is one of the critical path activities. So, demolition work is needed for systematic plan and management. However, contractors of the remodeling project established a rough plan and did not consider recycling wastes, safety of workers and structural stable of building. To improve this problem, a eco-friend process model of remodeling project is needed to be established. The process model is composed of five phases; 1) survey and analysis of general condition of demolition work, 2) prepare documents of demolition work 3) establishing demolition work plan, 4) demolition and inspection, 5) post-demolition management. Especially, demolition documents are based on establishing WBS, selecting the equipment and method, waste management and structure reinforcement. A process model of eco-friend demolition work is developed by using IDEF0 method.

The purpose of this study is to examine the case of constructing information and communication facilities in daycare centers and to propose an educational environment that can foster young talents who can lead the era of the fourth industrial revolution. In particular, after COVID19, a method was proposed to create an information and communication environment suitable for children to receive personalized education, and to create an environment for experiential education if possible, and at the same time to enable averaging of customized learning. Since there has been no research on information and communication facilities in daycare centers, we intend to place significance on starting, and in the future, to foster creative and contextual children, we will reduce the movement of teachers through smart speakers and mobile devices, and tailor the educational environment through AI data. I think that the design of the daycare center should be changed in the direction of making the product. To this end, the CM role of information and communication supervision is needed, and it is hoped that it will become a design standard for daycare centers after COVID19 by developing research on daycare centers.

Exemplary contracts of construction management (CM) including highway projects have been carried out in the civil engineering area over the past ten years. However, practical and administrative challenges as transitional circumstances have been revealed in the different participants of supervision, inspection and construction management. Thus, it is important to internally overcome problems and negative perception encountered in civil engineering, and to promote the efficiencies in construction cost and quality. In addition, external efforts should be put to market opening, globalization, and technology development for competitiveness and high value industry. While it is critical to establish the concrete CM system by collaborating with various participants, proven architecture and system have not been provided because of incorrect measurement of CM accomplishment, overlap of responsibility between CM and supervision, and slow deployment in construction field. This paper analyzed the current CM practices and business environments, and presented the possible solutions for strategy improvement of CM in the owner's view point.
