C.1.3 ORDER OF PRECEDENCE
This order of precedence section applies when there is a “true conflict.” A “true conflict” exists when two contract provisions contradict one another, such that it is impossible to comply with both provisions. For example, if one provision requires the contractor to do
X, whereas another provision prohibits the contractor from doing X, there is a “true conflict.” By contrast, if one provision requires a contractor to do X, and another provision requires the contractor to do X and Y, there is no “true conflict” if it is possible to do both
X and Y. In that situation, doing both X and Y complies with both provisions. Identified below, ranked from highest to lowest is the order of precedence. Where disparities between requirements exist that are not “true conflicts”, the Contractor shall seek COR direction. This is a conflict resolution tool; refer to contract Section J for the definitive list of applicable documents that apply to this effort.
