The Impact of Rework & Some Practical Remedies
Presented by:
James G. Zack, Jr., CCM, CFCC, FAACE, FRICS, PMP
Senior Advisor, Navigant Construction ForumTM

Rework in the construction industry is frequent and well known. It is a drain on productivity, profitability and timeliness of project delivery for both contractors and owners. Additionally, the need for rework can have spinoff or downstream impacts for all project stakeholders. The causes of rework are, likewise, very well known: design and construction changes; errors and omissions; project enhancements; operability changes; fabrication changes and errors, etc. While rework is common, the impact has not been thoroughly assessed, studied or discussed.

This presentation assesses and identifies the typical cost of rework on a wide range of project types. It shows how the cost of rework is frequently understated and provides an estimate of the true “average cost” of rework. The presentation also identifies the average impact of rework on project duration in terms of time as well as unrecoverable extended overheads and the cost of liquidated damages. Finally, the recorded webinar identifies a number of practical methods that can be employed by owners and contractors to substantially reduce both the cost and time impact of rework.


  • Learn about the reported cost of rework on construction as identified by a large number of studies
  • Learn the true cost of rework
  • Understand the estimate of the average amount of delay caused by rework on the typical construction project
  • Become familiar with the estimated amount of delay cost arising from rework
  • Be exposed to an estimating model which allows you to estimate the cost of rework on future projects
  • To gain information on a number of practical recommendations intended to reduce the amount of rework on future projects
