Text: The study found that effective design review practices result in less rework on the part of the construction contractor, fewer change orders to correct design errors and omissions, and lowering the cost of belatedly adding project upgrade features that should have been addressed in the original design.
Entailment: Construction contractors don't require as much rework if the design review process is effective.
Contradiction: Construction contractors often have to do more reworks regardless of the effectiveness of the design review process.
