Large-scale construction projects require various license and technologies for the manufacturing and handling processes. Also, the whole life cycle business process management determines the success of the project. Then, the efficiency of the business conducted by stakeholders and their possessed technology should be enhanced in order to strengthen their competitive power. For this reason, many experts pointed out to focus on the improvement of the life cycle process and efficient management. Since it is very important to keep up-to-date data and utilize it for work during the long-term project to reflect changes in the large-scale project, the most important part of the project management in project is information change management. Therefore, the objective of this study is applying configuration management(CM) technique in order to managing change data generated for planning in early phase. The result of this research will certainly assist the large-scale project managers in the development of information change management system.

현재 실적공사비 단가는 한국건설기술연구원에 의해 발표되고 있으며, 대규모 공사에서 수집된 공사비 자료를 분석하여 작성되고 있다. 따라서 소규모 공사의 경우 현행 실적공사비 단가를 적용함에 있어 불합리한 문제점이 발생하고 있다. 이러한 문제점을 분석하기 위해, 본 연구에서는 대 소규모 토목, 건축, 기계설비공사에 대한 실적공사비를 상호 비교하였다. 그 결과, 소규모 공사의 실적공사비는 대규모 공사에 비해 평균적으로 26.6%가 높음을 확인할 수 있었다. 한편, 노무비에 의한 대 소규모 공사의 실적공사비 차이는 18.4%이고, 재료비 경비에 의한 차이는 8.18%인 것으로 분석되었다. 또한 본 연구에서는 이를 시정하기 위한 소규모 공사의 실적공사비 보정방안을 제안하였다.

대형복합건설사업에서 생성되는 정보들은 장기간의 사업주기를 걸치며 다양한 사업주체간에 이동하며 변환 및 발전된다. 그래서 지연 등 사업수행에 문제가 발생하였을 때, 문제의 원인은 해당 업무가 아니라 그 업무와 관련된 이전 업무일 경우 정보흐름을 거슬러 올라가며 문제의 원인을 분석해야 한다. 그러나 복잡한 사업주체 및 업무들의 관계 때문에 사업에서 생성되는 정보들이 어떻게 흘러가는지에 대해 기존의 키워드검색방법으로는 이러한 정보흐름을 도출하기에는 적합하지 않다. 이에 본 연구에서는 대형복합건설사업의 정보흐름을 분석하기 위한 관계기반 정보검색기능을 구축하고 이를 사례 정보시스템에 적용하였다. 우선 기존 정보검색시스템의 활용동향과 대형복합건설사업의 특성을 분석하여 정보전달관계 검색시스템의 필요성을 도출하였고, 이에 적합한 시스템 구축 방법론 및 업무 간 관계 추론 알고리즘을 정립하였다. 그리고 구축한 시스템을 사례시스템인 도시재생사업의 업무정보시스템에 적용하여 그 활용방안을 제시하였다. 본 연구에서 제시한 정보흐름검색은 업무를 담당하는 주체 및 총괄 관리자가 사업 전체를 원활히 진행시키기 위한 주요 업무 도출 등에 이용할 수 있으며, 추가연구의 도구로서도 활용될 것으로 기대된다.

This paper shares our project management experience in the 2 large-scale projects in managing a diverse international project team of consultants and managing in a foreign land. The first part introduces the two projects, second part addresses management of the projects and the last portion presents some of the challenges we experienced and highlights the importance of understanding the peculiarities of the operating environment, their norms, cultures, effectiveness and limitations of conventional project management tools while operating in a foreign country.

SOC(Social Overhead Capital) projects such as road, power plant, airport or telecommunication facility construction require a large scale of cost, a long period of time and management of a number of sub-contractors. So systematic and efficient management tool in SOC projects is inevitable. Information system provides a valuable tool which can integrate and manage the large volume of information for SOC projects. This study investigates and analyzes the information system of nuclear power plant construction project. Based on this study, we can suggest the direction for designing information system for SOC projects.

Disputes seem to be synonymous with large-scale construction projects in Ethiopia. The purpose of this study is to determine the factors responsible for impacting the performance of Ethiopian public construction projects. To this end, 35 success and failure attributes responsible for impacting the performance of the projects were identified and presented to Ethiopian construction professionals in the form of a structured questionnaire, and responses were collected. The factor analysis conducted on the success and failure attributes influencing no-dispute performance separately resulted in six success factors and five failure factors. Further analysis using stepwise multiple regression indicates that owner competence and interaction among project participants have a positive impact on no-dispute performance. However, conflict among project participants has a negative impact on the no-dispute performance of Ethiopian public construction projects. Although Ethiopia-specific, the results reflect construction management problems common to both developed and developing countries. The findings are expected to help researchers and practitioners gain a better understanding of critical success and failure factors and to help them take proactive measures to avoid disputes in public construction projects.

On the contrary to the expansion of feasibility studies on public construction and development projects, there is few feasibility studies on S&T, especially large-scale basic research facilities. Based on this critical mind, we tried the first feasibility study on large-scale basic research facilities, that is, the 4th Generation Light Source. First, it is validated whether the construction of 4th Generation Light Source is economically feasible and second, if economically feasible, the optimal place and time for construction are analyzed by using Analytical Hierarchy Process. This research shows that the construction is economically feasible irregardless of scenarios on future bio-medicine industry growth and to construct at Pohang in 2006 is optimal strategy. On the basis of this analysis, the feasibility studies on large-scale basic research facilities are expected to be more expanded and developed.

Construction projects are large-scale projects that require extensive construction costs and resources. Especially, scheduling is considered as one of the essential issues for project success. However, the schedule and resource management are challenging to conduct in high-tech construction projects including complex design of MEP and architectural finishing which has to be constructed within a limited workspace and duration. In order to deal with such a problem, this study suggests resource and sequence optimization using constraint programming in construction projects. The optimization model consists of two modules. The first module is the data structure of the schedule model, which consists of parameters for optimization such as labor, task, workspace, and the work interference rate. The second module is the optimization module, which is for optimizing resources and sequences based on Constraint Programming (CP) methodology. For model validation, actual data of plumbing works were collected from a construction project using a five-minute rate (FMR) method. By comparing actual data and optimized results, this study shows the possibility of reducing the duration of plumbing works in construction projects. This study shows decreased overall project duration by eliminating work interference by optimizing resources and sequences within limited workspaces.

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.
