Instructions: B105™–2017, Standard Form of Agreement Between Owner and Architect



AIA Document B105–2017 is a standard short form of agreement between owner and architect. B105–2017 is for use on a project that is modest in size and brief in duration. B105-2017 replaces B105-2007, Standard Form of Agreement Between Owner and Architect for a Residential or Small Commercial Project. For larger and more complex projects, other AIA owner/architect agreements are more suitable. AIA Documents B105–2017 and A105™–2017, Standard Short Form of Agreement Between Owner and Contractor, comprise the Small Projects family of documents. B105–2017 is intended for use with A105–2017, which it incorporates by reference. B105 is extremely abbreviated and is formatted more informally than other AIA agreements. Although AIA Documents A105 and B105 share some similarities with other AIA agreements, the Small Projects family should NOT be used with other AIA document families without careful side-by-side comparison of contents. For all document details and a record of changes, see the summary  »

Insert the amount of, or the method for calculating the Architect’s compensation. Some sample methods of computing compensation are provided below: 

Multiple of Direct Salary Expense. Compensation for services rendered by principals, employees and professional consultants shall be based on a Multiple of Direct Personnel Expense. Direct Personnel Expense is the direct salaries of the architect’s personnel engaged on the project and the portion of the cost of their mandatory and customary contributions and benefits related thereto, such as employment taxes and other statutory employee benefits, insurance, sick leave, holidays, vacations, pensions, and similar contributions and benefits.

In addition, a reasonable allowance for contingencies shall be included for market conditions at the time of bidding and for changes in the Work during construction. The Construction Cost, however, does not include the compensation of the Architect and Architect’s consultants, the costs of the land, rights-of-way, financing or other costs which are the responsibility of the Owner. 

After inserting the amount or method of compensation, insert the amount of the initial payment, which is to be determined by the parties.
