The government introduced private infrastructure projects in order to reduce its financial burden by introducing private sectors efficiency and creativity and by utilizing their funds. Through revision, the act on the private investment of the infrastructure, many changes were made in the private investment system. The evaluation task to assess the project proposer's capability and to select a promoter is regarded as the most important process for fairness and transparency of the project. In this study, the improvement of project plan evaluation task of current private infrastructure projects is proposed based on the standard guideline for evaluation procedure of private infrastructure projects provided by Korea Development Institute. In addition, software program for evaluation procedure is made to improve the efficiency and enableconvenient evaluation task.

The research and development stage can improve the goal level of the project through systematic operation and management of systems engineering. The test evaluation tasks in the R&D process have a lot of connections with the system engineering in terms of requirement management, and the methodology for deriving the requirements when establishing the test evaluation items has been consistently required. In this paper, we propose the process of effectively establishing and using QFD (Quality Function Deployment), a tool to manage customer requirement, and drawing up HOQ (House of Quality) in the search and exploratory development stage of the self - propelled mortar project.

It has been debating on the performance evaluation of professional construction management (PCM) services since its introduction to Taiwan's construction industry more than a decade ago. Several evaluation systems were proposed by previous researchers. However, there has no comparison study been conducted for the feasibility, effectiveness, and appropriateness of these systems to the performance management (PM) of practical PCM services. This paper is intended for this end to compare the existing PCM performance evaluation systems in Taiwan. A real world design/build (D/B) building project was selected for case study. The result of case study concludes and compares the pro's and con's of the three systems. At the end, it recommends strategies for selecting the most appropriate PCM performance evaluation for PCM services.

This study is to evaluate the 'Private antidesertification afforestation support project' in the Kubuqi Desert through a survey of local residents and interviews with relevant personnel. Based on this survey, gender, age, and occupational differences in perception of the project were analyzed. In addition, the project was evaluated based on the OECD/DAC criteria using survey results and in-depth interviews with the relevant personnel. The survey analysis results show that the participants answered most of the questions positively, claiming that they were receiving social, economic, and environmental benefits through the project. However, most of the participants answered negatively to questions regarding the understanding of the project and relevant information. Gender differences in perception of the project were not found, whereas, age and occupational differences in perception were found. Older age groups showed higher levels of perception. Participants in the agro-livestock industry and office workers showed higher levels of perception compared to middle/high school students, the unemployed and college students. Teenagers, in particular, showed the lowest level of perception of the project, and thus, promotional activities targeting teenagers should be conducted in the future. Results of this evaluation of the project based on the OECD/DAC's five criteria (relevance, effectiveness, efficiency, impact, and sustainability) showed that the project operated effectively for the most part.

The post-evaluation system after construction projects can evaluate estimates of use demand, project cost, and project schedule estimated in the planning phase of construction projects in public sector. Thus, it was introduced in 2000 for the purpose of reduction in future errors during similar constructions by project orderer by referring the post-evaluation results. However, many barriers to the post-evaluation system after construction projects have been reported due to evaluation systems that lack objectivity and reliability and lack of main bodies that utilize the system. Thus, this study derived implications for improvements of the post-evaluation system in Korea by benchmarking building project evaluation system and management as well as utilization systems of developed nations. Then this study conducted a survey with experts who have experienced activities in the post-evaluation committee and members of post-evaluation for public project owners. Therefore it identified the need of installation of specialized post-evaluation institutions as well as functions and work tasks to be taken by specialized institutions. Based on the analysis results, this paper provided revision drafts of related legislations and guidelines to be effective in post-evaluation. Through the study results, many trial and errors can be reduced in similar projects in the future by performing in-depth analysis on large-scale construction projects and repeatedly applied building project practices can be improved to raise technical competitiveness if the specialized institution is installed.

In this study, We developed an evaluation system for the interim check of Integrated Rural Village Development Project and analyzed its applicability to an actual evaluation process through a pilot evaluation on regions selected. The evaluation system consists of documentary assessments(30%) and field inspections(70%). The documentary assessments are quantitative assessments on check-lists reports by self-evaluation prepared by local governments. The field inspections are qualitative assessments by evaluation teams. Sixteen evaluation indices were developed for documentary assessments and seven criteria were designed for field inspections. For a pilot evaluation, one region in each province excluding Jeju Do, eight regions was selected and the field inspections due to circumstances was proceeded in two regions. The results of documentary assessments indicate that most of regions are evaluated low in project performance attributable to the delay in security for sites. In the field inspections, it appears that most of the regions evaluated high at the documentary assessments got a high point from them. They also show that coordination of action plans, rather than quantitative achievements, is a base determining success of the projects.

PERT(Project Evaluation and Review Technique) is typical method in order to probabilistically establish the schedule plan for large scale complex project or mega project. PERT technique is impossible to estimate relationship of each activity probabilistically when there are overlapping relationships because it is limited to Finish-to-Start(FS) relationship. In order to overcome this kind of limitation of PERT technique, PLET(Probabilistic Linkage Evaluation Technique) has been suggested to probabilistically estimate project duration for various overlapping relationships for each activity. However, estimating project duration by PLET technique only considers uncertainty of relationship between activities and not activity time, thus it is not the perfect duration estimating method. The main objective of this research is to propose the integration model of PERT and PLET and verify its probabilistic validity. By verifying application of time calculation method of integration model in practical case, this research will suggest probabilistic project duration estimating method in schedule plan of high-risk construction industry.

Since the late 1990s Korean housing authorities and private companies have been pursuing various initiatives towards sustainable neighbourhood design, however, there has been no attempt to examine their progress. This research aims to suggest a sustainability evaluation framework and analyse the progress of sustainability of a cutting edge project: Shinjung Environmentally Friendly Housing Estate Development, using that framework. The results of the analysis suggest that the project failed to make Significant progress in the sustainability evaluation criteria compared to normal projects in Korea and there exist significant barriers: economic/financial barriers; institutional/structural barriers; and implementation barriers within current planning and design practices. Most of the project's design strategies were simply adopted and used as a marketing tool without public participation, sustainability targets or benchmarking for sustainability. Furthermore, most of the responsibility for maintenance was left to residents who normally lack the knowledge, experience, interest and money to carry out such tasks. These problems cause significant concerns over the future success of the project toward sustainability. The experience of the Shinjung project also highlights the need for a more proactive central and local government stance towards sustainable neighborhood design.

Development of social overhead capital (SOC) requires huge national finance, and performance issues such as cost-efficiency, safety, and environment have been constantly raised. However, currently each construction client has limited access to its own projects' performance without analytic methodology for industry-level comparisons and benchmarking for improvement. To overcome this problem, this study proposes a comprehensive performance analysis framework for post-evaluation of large-scale construction projects. To this end, this study performed a case study of advanced countries (the U.S., the U.K. and Japan) and consultation with related experts to develop a tailored performance analysis framework for the Post- Construction Evaluation and Management system in Korea. The developed framework covers three categories (project performance, project efficiency, and ripple effect), nine areas (cost, schedule, change, safety, quality, demand, benefit-cost ratio, civil complaint, and defect), and 31 detailed metrics. Using industry-level project performance database and statistical techniques, the proposed framework can be used not only to diagnose excellent and unsatisfactory performance areas for completed construction projects, but also to provide reference data for future similar projects. This study can contribute to the improvement of clients' performance management practices and effectiveness of construction projects.

Improving long-term performance in highway projects is an imperative goal for public administrations. Project delivery and procurement methods might provide an opportunity to align design and construction processes with this goal. Previous studies have explored whether project delivery methods impact the long-term performance of highway projects. However, these studies did not focus specifically on how core elements within the procurement might relate to long-term performance. Thus, this research aims to fill this gap by exploring to what extent and how long-term evaluation criteria are considered in design-build best-value procurement of highway projects. To this end, content analysis was conducted on 100 projects procured between 2009 and 2019 by 19 DOTs across the U.S. The analysis of 365 evaluation criteria found that (1) roughly 11% of them related to long-term performance. (2) The weight given to these criteria in the overall technical proposal was lower than 30%. (3) Sixty-five percent (65%) of long-term evaluation criteria focused on design while 15% related to materials and technology, respectively. The results of this study are a first steppingstone to initiate a deep exploration of the relationship between procurement practices and actual project performance. Currently, with sustainability and life cycle assessments being top concerns in infrastructure projects, this line of research might be of particular interest to DOTs and highway agencies across the U.S. and worldwide.
