B133-2019

AIA Document B133™–2019 is a standard form of agreement between Owner and Architect intended for use on projects where an Owner employs a Construction Manager to act as an Advisor during the preconstruction phase. At a time to be mutually agreed upon by the Owner and the Construction Manager, and in consultation with the Architect, the Construction Manager prepares a Guaranteed Maximum Price proposal or Control Estimate, as applicable, for the Owner’s review and acceptance. Thereafter, the Construction Manager constructs the Project on a Cost of the Work Plus a Fee basis, either with or without a Guaranteed Maximum Price, and the Architect provides contract administration services during the construction phase. B133–2019 assumes that the Construction Manager will provide cost estimates and schedules for the Project. B133–2019 is intended to be used with AIA Document A201®–2017, General Conditions of the Contract for Construction, which it incorporates by reference and either 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 or 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.
