This article adopted the concept of decision support to establish a CPM-based construction quality inspection and decision-aid system (CQIDS) to improve ineffective field quality inspection processes. The system consists of two main subsystems: the database subsystem and the decision subsystem. The database subsystem contains information about quality specifications, shop drawings, checklists, and corrective actions that comprises a multimedia network. The decision subsystem contains statistical algorithms to facilitate in situ quality data analysis. Moreover, in order to execute quality management in a timely fashion, quality management timetables are generated automatically from the CQIDS and sent to field quality supervisors by integrating quality management activities within the project's own CPM network.
