The OAA supports the use of industry standard documents. The use of standard documents allows the parties to concentrate on project specific issues  rather than boilerplate sections. To that end, the OAA developed several standard contracts for use with clients and subconsultants which balance the needs of all parties.

The suite of OAA contracts are organized numerically and each contract comes in variants for Architects and for Licensed Technologists OAA. OAA 900-2021 is the latest form agreement to be used between an OAA member and a subconsultant.

There are corresponding usage Guides with instructions for the contracts which, provide background information about how to fill in and use the contracts. Please ensure  you reference all the documents provided below before using this subcontract.

For additional information, consult the Index to OAA Contracts and Guides and the Contracts for Professional Services page.
