AIA Document A422–2018 is a Work Order that provides the Subcontractor’s scope of Work, Subcontract Time, Subcontract Sum, and other terms pertinent to the specific Work Order. It is intended for use when the Contractor and Subcontractor have entered, or will enter, into a Master Agreement, which sets forth the common terms and conditions applicable to all Work Orders. A422–2018 is not a stand-alone agreement and must be used in conjunction with a Master Agreement. A422-2018 is coordinated for use with AIA Document A421™–2018, Master Agreement between Contractor and Subcontractor. The Master Agreement plus Work Order contracting method allows multiple scopes of Work to be issued quickly without renegotiating the terms and conditions of the Contract.
