If the defect is realized after substantial construction work has been completed, and therefore requires rework, delay, or additional work beyond that which would have been required by defect-free drawings, the cost would still be allowable, but the additional cost of rework or delay is unallowable.
The additional cost is measured as the difference between the cost which would have been included in the bid based on defect free drawings and the actual cost of the change order.
