Change Order Causation; Who is the Guilty Party?

This research seeks to determine the most common causes of change orders and to uncover which divisions of work are most susceptible to the greatest number of changes. The research concludes that the majority of changes result from plan errors and omissions and further that as a division of work mechanical, electrical and plumbing (MEP) systems are most susceptible to changes. By defining these and other problems, it is anticipated that future research will build off this work and provide solutions to reduce the number of changes orders on construction projects.
