• A contractor is usu. entitled to charge for extra work consisting of labor and materials not contemplated by or subsumed within the original contract, at least to the extent that the property owner agrees to a change order. Materials and labor not contemplated by the contract, but that are required by later changes in the plans and specifications, are considered to be extra work.
— Also termed additional work. [Cases: Contracts 232(1). C.J.S. Contracts §§ 393–398.]
