This free guide serves two purposes: it provides guidance to assist in preparing the Contract for Construction, and it provides model language that may be used to amend or supplement the Contract for Construction.

However, the guidance and model language presented is also applicable to AIA Documents A102–2017, Standard Form of Agreement Between Owner and Contractor where the basis of payment is the Cost of the Work plus a Fee with a Guaranteed Maximum Price, and A103–2017, Standard Form of Agreement Between Owner and Contractor where the basis of payment is the Cost of the Work plus a Fee without a Guaranteed Maximum Price, A133–2019, Standard Form of Agreement Between Owner and Construction Manager as Constructor where the basis of payment is the Cost of the Work plus a Fee with a Guaranteed Maximum Price, and A134–2019, Standard Form of Agreement Between Owner and Construction Manager as Constructor where the basis of payment is the Cost of the Work plus a Fee without a Guaranteed Maximum Price.
