Change Order
A change order is a written instrument used to modify a construction contract, typically stating the change in the work and any adjustment to contract sum and contract time. AIA contract commentary describes the change order as the primary means to modify the contract for construction and provides a formal definition emphasizing signatures and agreed adjustments.
