Knowledge-based standard progress measurement for integrated cost and schedule performance control

Though the progress of construction projects is most often used as a critical index for effective project management, the method, structure, data, and accuracy of detailed progress measurement may vary depending on specific characteristics of a project. This situation can lead to misinterpretation of the project status, especially under a multiproject management environment. It is also a daunting task for the inexperienced engineers to formulate and monitor the project-specific work packages. At the same time, maintaining very detailed and highly accurate progress information requires excessive managerial efforts. In order to address this issue, this study proposes the concept of standard progress measurement package. Issues for standardization of the work breakdown structure that can embody distinct characteristics of different construction projects are investigated. The proposed methodology facilitates automated formulating of work packages by using a historical database and also automates the gathering of progress information through the use of standardized methods and tools. A case-study project is evaluated in order to examine the practicability of the proposed system.
