A121-2018

AIA Document A121™–2018 is a Master Agreement between the Owner and Contractor. It is intended for use when the Contractor’s scope of Work will subsequently be specified through the use of one or more Work Orders. A121-2018 provides only the common terms and conditions that will be applicable to each Work Order. Use of A121 plus a Work Order creates a contract that includes both the terms and the scope of Work. A121-2018 is coordinated for use with AIA Document A221™–2018, Work Order for use with Master Agreement Between Owner and Contractor. The Master Agreement plus Work Order contracting method allows multiple scopes of Work to be issued quickly without the necessity to renegotiate the terms and conditions of the Contract. It may be used on projects with a stipulated sum; cost of the work plus a fee, with or without a guaranteed maximum price; or other payment method determined by the parties. If using a cost-plus payment method, the parties will also use A121 Exhibit A, Determination of the Cost of the Work.
