It started at the very beginning while preparing the ground for the forming crew. Bob had to delay the forming crew by a half day because the job was graded incorrectly. To add insult to injury, the forming crew then placed the forms several inches off the mark in three critical places. Having corrected these two mistakes, Bob thought he was safe until the concrete truck showed up with the wrong mix, causing another delay with additional labor cost. Now Bob could only watch as a once-profitable job was shriveling slowly toward breakeven.
Many contractors have dealt with the consequences of rework. Its cost often is camouflaged in production costs, further hidden within labor, materials, and equipment costs already established. Rework robs you of up to 2% in profits without being readily apparent. That's why we call rework the "silent assassin."
