Real-time information is vital to enhance dynamic control and management via information sharing and analysis
in order to reduce construction conflicts and project delays. However, most construction project management programs
are ineffective for project prompt responses, especially with respect to change management. This work presents a
novel construction project management system called the web project-based change management (WPCM) system. The
WPCM system responds to changes in information efficiently in order to facilitate change management among project
participants (e.g. general contractor, suppliers, and subcontractors) in a construction project environment. Capable of
increasing information sharing in construction change management, web-based technology can also provide cost savings
via the Internet. A case study involving a commercial building project in Taiwan demonstrates the effectiveness of both
the proposed WPCM system and information sharing in change control during the construction phase. In addition to increasing
the efficiency of change control and management for a general contractor, as well as dynamic project tracking
and management, the proposed system enables subcontractors and suppliers to access and manage the change information
timely. Future work should implement the system functions comprehensively and apply the system to additional
projects more strictly for further verification of its reliability.
