Progress monitoring and control is one of the most important tasks of management project. Basically, construction works produce a lot of information that were required by top managements of construction organizations to track the work progress on site. A recent issue highlighted by top managements is inefficiency in obtaining information from project site on time. Hence, the focus of this research is to establish a computerized information system that can be utilized by top management in order to evaluate the construction progress. The aim of this research is to develop a computerized project progress monitoring entitled Executive Information Site Monitoring System (EISMS). In order to develop EISMS, Classic Waterfall Model has been considered as a basis for system development. The development process started by identifying system requirements, followed by EISMS proposal, EISMS design, EISMS implementation, and ended up with system validation and verification. In conclusion, EISMS was successfully developed and implemented during construction phase which allows top management of construction organization to monitor the construction site progress more efficiently and helps them in the decision making and taking timely appropriate action.
