After nearly four decades as a contracting officer, construction manager, and a construction claims consultant, author James G. Zack, Jr. has concluded that employers routinely make a number of mistakes on projects that actually cause disputes. In the article “Ten Mistakes Employers Make that Cause Disputes”, Zack defines the more common mistakes owners/employers make that invite such disputes. Each is avoidable if the owner/employer adheres to the terms of their contract, deals with the contractor fairly, and proactively addresses issues as they arise. Construction projects are a fertile field of endeavor, ripe for disputes. There are many parties involved in a construction project and the opportunity for things to go awry is significant. However, avoiding these common mistakes can prevent a costly dispute and help to keep a project on track.
