Abstract:

Acquisition of scheduling data for construction project information management is a complicated task. Historically, there has been a fundamental disconnection between cost estimation and scheduling. This disconnection leads to the lack of a source of information for the acquisition of scheduling data and forces schedules to be based too strongly upon expert intuition. To solve the problems, a model, Work Packaging (WP) using Design Components (DC) is developed and described using Object-Oriented Techniques (OOT). The model's approach eliminates the disconnection between cost estimation and scheduling, and provides procedures for schedule data acquisition. Cost estimation and scheduling are integrated throughout the model.
