Internet-based database management system for project control

Purpose - The objective of this paper is to develop an efficient project management system to track and control construction activities for contractors and/or project managers. Design/methodology/approach - The work package model is utilized to break down project data into activities and work tasks. The data structure of a project is represented using the entities-relationship methodology. A relational database stores all of the project data. The earned value method calculates the cost and schedule variances. The internet-based platform with three-tier client-server architecture is chosen for system implementation. Findings - The developed project database stores all of the project data necessary to perform project control functions. The implementation of the project database management system is efficient. The developed system provides real-time data sharing and a collaborating environment in support of project control. Originality/value - Time and cost control are essential management functions for achieving successful delivery of engineering, procurement and construction (EPC) projects. The developed system can assist contractors and/or project managers in tracking and control of their construction projects in a real-time manner.
