Change orders are one of the main problems in construction projects. The objectives of this study are identification and evaluation of causes and effects of change orders as well as procedures of change orders control on building construction projects in Islamic Azad University (IAU) Shoushtar Branch in Iran. It is found that contractor's financial difficulties, previous construction delays by other contractors working on different contracts were important factors responsible for change orders in construction projects. However, there are five important factors that have been identified as having the greatest effects on change order. Finally, important methods in procedures of change orders control are recommended. Although, the research is restricted to IAU-Shoushtar Branch, the findings of construction management problems are common to other universities in their building construction projects.
