Prototype web-based construction project management system

Abstract

This paper presents a conceptual model of a metadata-based information system for data exchange among Web-based documents for construction project management. The system retrieves useful data from the original documents, reorganizes the information according to specific tasks or users, and displays the information in an integrated web page. The study identifies the comprehensive functional requirements from existing Web-based collaboration systems, and finds out new user requirements by way of a Web-based survey in Singapore. Based on the requirement studies, a prototype model is developed using unified modeling language. Implementation of the conceptual model uses extensible markup language technology. Discussions on major concerns about information security, data accessibility, and service quality are included in this paper.
