20 Common Mistakes that Construction Owners &
Contractors Make that Cause Claims and Disputes

Presented by:

James G. Zack

         Phil M. Spinelli
Navigant Consulting, Inc.


When asked about the most common causes of construction claims, owners and contractors will likely recite a lengthy list including changes, delays, site conditions, lost labor productivity, etc. However, a recent global survey of the top five causes of claims found that contract administration issues are the largest cause of claims. The Navigant Construction Forum™ has determined that contract administration issues are not caused solely by one party to the contract but rather are caused by both owners and contractors.

This presentation identifies the top 10 mistakes owners make that cause claims, as well as the top 10 contractor mistakes that give rise to disputes. With each, the expert presenters will share practical advice on how to avoid such mistakes.

Topics covered in this recorded 90-minute webinar include the legal risk and practical problems that arise:


  • Due to the failure to settle delays as they arise
  • When RFI’s are used to correct errors or redesign the project
  • As a result of discouraging written notices
  • When you proceed with changes without a written change order
  • When time and cost damages are not tracked separately from base scope time and costs
  • When contractors finance owner-caused changes
  • And much, much more!


Attend this information-packed webinar to get answers to these questions and more. You will leave this event with insight into the 20 common mistakes to avoid and smooth the way to successful project completion.

Who Will Benefit?
This recorded webinar is a must if you’re a public or private owner, construction manager, contractor, subcontractor, consultant, architect or engineer.
