Under increased complexity and uncertainty of overseas construction projects, it is important for construction companies to improve their own project risk management capabilities instead of risk-taking strategies to secure competitiveness in the overseas construction market. Although most of the risks occur in project execution stage, many previous studies focused on planning stage including risk identification and analysis among PRM process. Therefore, this study aims to verify the effectiveness of whole PRM process during project execution stage through empirical study on participants of overseas construction projects. As the result it was found that first, the factor directly affects the project success is the execution process of PRM. It implies that appropriate actions such as appointing charged manager for risks, timely implementation of responding plan, continuous risk monitoring and updating established plan are the key for contribution to the project success. Second, the importance of communication in PRM is also found, which is not conducted at a specific but throughout the entire PRM process and need to be managed as essential factor for successful PRM..

Recently, defects that occurred during the construction of apartment houses have become a social issue. Defects in apartment houses lead to waste of resources and economic loss, causing psychological and physical damage to customers, and a decrease in reliability and financial loss to construction companies. The purpose of this study was to analyze the impact of defect occurrence according to the difference in project management level in the apartment housing construction stage, and to investigate the extent to which the project manager's experience affects the defect occurrence rate. For the empirical analysis of the study, statistical analysis was conducted using data collected from 130 actual projects. The results of the analysis showed that schedule management, cost management, and quality management had a positive effect on reducing the defect occurrence rate in the execution stage of apartment housing construction, while human resource management productivity had a negative effect. This study theoretically demonstrated the importance of project management, and in practice, showed that schedule management, cost management, and quality management should be faithfully performed in the execution stage to reduce the rate of defects after project completion. It was also suggested that hiring an experienced project manager would help reduce project defects.

The “Carbon Neutral” has become the most important goal to achieve in the era of the climate change crisis. K-water has prepared a roadmap for implementing “Carbon Neutral” by 2050. However, only the reduction targets and strategies for scope 1 and 2 have been set, so the management of carbon generated during the construction project and upfront carbon is not being implemented. Therefore, in this study, the criteria and methodology for estimation carbon emissions in the construction sector at domestic and foreign were reviewed, and a methodology for estimation carbon emissions suitable for K-water construction projects was presented, and a case study was conducted. As a result, most of the carbon emissions were more than 90% of the upfront emissions due to material production. Therefore, upfront carbon management is required for carbon management of K-water construction projects, and it is necessary to quantify carbon emissions through GHG construction inventory, etc., and to establish strategies for future reduction technologies.

Stakeholder management in construction projects is an important factor in project performance creation. The purpose of this study is to verify the effect of the recognition of the importance of the quality influence factors among the stakeholders of the construction project on the perceived quality and the project performance. The impact of the project management methodology on the project performance has been actively researched, but there is little research result on the project stakeholders. The projects to be researched are apartments and buildings that have been completed within the last five years of domestic large construction company. The method of survey is to measure the consensus of the importance of the quality influential factors among the three parties such as the ordering party, the design supervisor and the constructor, and confirm whether the agreement affects the quality of the actual project. Finally, the research model was verified by surveying the satisfaction of the client on the final product. The results are as follow. The degree of agreement on the importance of quality influential factors among stakeholders has a significant effect on perceived quality. In the relationship between perceived quality of influence factors, organizational (support) quality influenced technological quality and managerial quality, and technological quality and managerial quality also have significant influence on resource quality. The results of analysis showed that perceived quality of resources strongly influenced project performance. The remaining three experienced qualities also significantly affect project performance.

BIM(building information modeling) has been actively applied to construction industries and to maximize its application through the life cycle of structure, various relevant technologies have been proposed. In particular, 4D sequencing management and 5D cost-related management were introduced as an improved version of the design review and interface control by 3D information design. On the other hand, the virtual construction using virtual construction equipment can sophisticatedly handle capacity, dynamic movement, collision boundaries of actual construction machines but it still stays at a low level in a technical sense. In this study, simulation systems based on BIM involving virtual construction equipment have been developed; then it is applied to the actual construction project to evaluate the safety and efficiency of construction equipments. It was confirmed that the simulation systems can be utilized to construct virtual construction site by using an effective 3D library of construction equipment and can plays a key role to secure construction safety and economic feasibility. Specifically, the simulation system are very useful for decision making by construction managers to select the optimum equipment and construction method with a better understanding for safety and cost-saving.

6 sigma is a management innovation strategy which improves most of all managerial processes including transactional and project based operations such as marketing, purchasing, accounting, and construction. Even though 6 sigma is trying to solve problems from the customer’s viewpoint in the scientific manner, project leader feels some difficulties in implementation because of several reasons. Especially the difficulties are prevalent in construction site. This paper investigates the cause of the difficulties through questionnaires, analyzes the investigation results, and verifies the critical success factors of 6 sigma implementation. Factor analysis has been usually employed in reducing quantity of data and summarizing information chaos. In this study, several variables from questionnaires are grouped into just only four factors by the process of factor analysis. The critical success factors are extracted as project management system, implementation mechanism, site condition, and project ownership. Some ideas for each individual success factor are suggested, which are expected to be useful in successful implementation of 6 Sigma in construction site.

A prediction of construction cost in preparation for construction document is calculated in compliance with the unit cost in Public construction of korea. This eventually means that the reasonable construction cost of a building can't be determined before construction document phase cost of construction is settled and that the cost of construction is calculated inefficiently because of connection failing between cost management of detailed estimation and information. To improve those problems, therefore, Cost estimating model of structural building elements with approximate quantity survey method is suggested in this research. The model predict the amount of materials and the cost of construction on the basis of historical similar cases. In the direction of data analysis of this research, ratio statistics value is put to practical use to fit into the peculiarities of approximate estimate of each work trade on the basis of actual data amount of materials of historical cases. In addition, the construction phase is connected through the result of a approximate estimate sorted by elements, details work trade.
