The construction process involves a large number of participants, various forms of project organisation, and the use of numerous different types of computer applications. These characteristics bring forth the need for intensive data exchange and information sharing based on the integration of various applications. Different types of construction projects undertaken by the ITU Construction Works Office are continuing to expand and a serious need for the management of all construction related activities are recognised. With such a rapid spurge of projects, a need is recognised for a system that would ensure the effective management of the ITU's campus construction projects. This process involves the integration of such information in a format that can be transferred to the level of the Rector for effective decision-making. The objective of this study is to develop an integrated data management tool including decision-support utilities for communicating, organising and managing project information using web-based technology and the network. By integrating data, extracted from the specific software packages, the system generates a variety of reports at the multiple project level for multi-task decisions to achieve completion of the multi-projects on time within budget. The paper concludes with a discussion of how the proposed system contributes to the development of the construction industry.
