Project plan and control is a highly skilled task which is vital for business success, and Project control systems are important for successful project execution. To support construction process management effectively, an integrated cost and schedule control function is required to collect quality data in a timely manner and to provide quality historical data for future planning of new projects. In Korea construction industry, the development and implementation cases of a project control system which to efficiently support construction project planning and controlling processes, have been increased to ensure a project success and the profitability of a construction company. To contribute to improving practical effectiveness of a project control system, the paper reviewed and analyzed the current trends and functional features of current project control systems. And it also described the pending issues and their solutions faced on previous project control systems.

서울시는 복개천이었던 청계천을 복원하여 도심지를 통과하는 하천을 만들기 위해 청계천 복원 공사를 수행하고 있다. 청계천 복원 공사 구간을 포함하는 유역에는 서울시 지하철 1, 2, 4, 5, 6호선 등이 통과하고 있으며, 도시 내 비수시설, 하수관거시설 등 자연적인 수문현상에 영향을 주는 인위적인 요소들이 복합적으로 존재하고 있다. 때문에 청계천 복원 공사 후 유역내의 여러 요인들과 공사의 정도에 따라 누수가 발생할 것으로 예상된다. 공사 후 청계천에서의 누수율에 대한 측정은 공사의 성공여부를 결정하고, 향후 지속적인 누수가 예상되는 청계천의 유지 보수에 있어서 매우 중요하다. 특히 청계천의 손실량의 대부분을 차지할 지하로의 누수에 대한 측정은 매우 중요하다. 따라서 누수율을 측정하고, 누수율과 주변 요인들과의 관계를 추정할 수 있는 수문모델링을 수행할 필요성이 있다. 수문모델링은 일회성으로 끝나는 것이 아니라 지속적으로 수행될 필요가 있는데, 그러기 위해서는 청계천 유역에서의 지속적인 수문관련 인문 자연자료를 획득하여 정리할 필요성이 있다. 본 연구에서는 청계천 복원 공사 구간의 유역에 대한 인문 자연자료를 GIS(지리정보시스템)을 이용하여 수치도면과 속성테이블 형태로 데이터베이스화한다. 그럼으로써 청계천 주변 유역에 대한 도시형 수문 모델링 연구에 활용하고, 아울러 공사 후 지속적으로 누수율을 측정하는데 자료를 원활히 제공하여 청계천의 유지 보수에 도움을 줄 수 있는 체계를 마련하였다.

Owners, local autonumous entities, have a burden on operating project for the lack of their management capacity such as specialty and human resources. In this reason, they want to perform project with CM methods. But there have been only a few case of CM operation and application in a huge construction project. The complex formations of CM and responsible management are used in those project. This situation originates in the lack of CM specialist. Because the CM service used in those case is generally performed as the mixture of responsible management service and design management service, it is not the prototype of CM. The purposes of this study are to present the solutions to the problems concerned with the design development phase management, design phase VE, the application of Fast-Track, PMIS operation and CM execution, etc, and establish the plan to perform CM services efficiently in the public sector through analyzing the case of CM application in Gwangjin-Gu Culture & Sports Center.

This study refers to development of WBS(Work Breakdown Structure) and Activity sample for integrated cost and schedule control system of sample bridge work in the field. The conclusions from this study may be summarized as following 1. It showed that the level of detail to network's activities depend upon schedule's intended purpose. 2. It is more effective 'activity to cost package model' than 'activity to resource model', for integrated cost and schedule control reflect the characteristics of domestic construction industry.

Nowadays, domestic construction companies make an effort to share knowledge and experience accumulated while conducting a project. One way of improving knowledge sharing is to develop specifications which are linked to the expert's knowledge and experience based on the specification classification. Therefore, the purpose of this paper is to review the current domestic specification system and develop the specification linked to the construction lessons learned database. It is expected that the proposed specification system will support the decision making process by effectively providing the knowledge and solution.

As the working design process of Turn-Key projects is a basic process for the final contract, this process has lots of business decision to be made. Because such results of business decision can be the basis on contract documents, it is the step which needs a through management for Turn-key project. But in case of domestic construction companies, because those are not organized process of working design process, project manager has had lots of trouble at each process to make the business decision. As a means of settling the problems, this research is initiated. First, working decision management process is identified and generalized by interviews with project managers. Second, cases that actually happened in the project are investigated and categorized. Third, response plan to solve the problems and check lists to prevent the problems are suggested. Finally, the process, cases, response plan, and check list are integrated using CBR for future reuse.

The contractors which execute the design-build project have difficulties in design management and contract administration in the pre-construction phase because they have managed construction projects focused on only construction phase so far. Moreover, they have to manage the design development stage without any contingency following-up various design revisions from the design reviews of outside experts. Therefore, the design management in the design development stage is a critical success facto. of the design-build project. The objective of this study is to structure the problems in the management skill for design development phase in the domestic design-build projects and to suggest a design development management method to settle the problems. To achieve these objectives, this study 1) analyzes the prior studies about the design-build procurement methods, 2) designs and performs a case study to embody the problems of the domestic design-build projects, and 3) proposes a method of design development management by analyzing the results of case study and interviewing experts.

The major objective of construction process control(CPC) is to provide construction managers with operational information that will help reduce project duration and save project cost. However, the CPC in Korea is being applied to construction projects with some basic problems such as the inconvenience of CPC S/Ws and the process control unconcerned with construction information classification system and computer system to integrate cost and schedule. This study analyzes the present condition of CPC including the basic problems, and then suggests the reform measures in technical and operational viewpoints to reduce construction risk. The focus of study is on the technical improvement for the application of construction information management system applicable to both cost estimating and schedule management.
