When contractors seek additional compensation for changes, differing site conditions or other delays, they must convince the DOT or court of the amount they are entitled to be paid.
Whenever these types of events occur on large highway or infrastructure construction, there is usually a substantial loss of productivity. Yet, contractors are frequently unable to show what's an appropriate increase.
One way to determine lost productivity is by determining what is known as the measured mile – comparing the cost of “impacted” work with what it takes to do "normal" work.
