AIA Document A142™–2004 replaces AIA Document A491™–1996 and consists of the agreement and five exhibits: Exhibit A, Terms and Conditions; Exhibit B, Preconstruction Services; Exhibit C, Contractor’s Scope of Work; Exhibit D, Determination of the Cost of the Work; and Exhibit E, Insurance and Bonds. Unlike AIA Document B491–1996, AIA Document A142–2004 does not rely on AIA Document A201™ for its general conditions of the contract. A142–2004 contains its own terms and conditions.
A142–2004 obligates the contractor to perform the work in accordance with the contract documents, which include A142 with its attached exhibits, supplementary and other conditions, drawings, specifications, addenda, and modifications. Like AIA Document A141™–2004, AIA Document A142–2004 requires the parties to select the payment type from three choices: (1) Stipulated Sum, (2) Cost of the Work Plus Design-Builder’s Fee, and (3) Cost of the Work Plus Design-Builder’s Fee with a Guaranteed Maximum Price.
