AIA Document B110–2021 is a one-part standard form of agreement between owner and architect for design and construction contract administration on a custom residential project. B110-2021 is based on B101-2017, Standard Form of Agreement Between Owner and Architect, but B110 is tailored specifically for use on a custom residential project.
Services are divided into basic, supplemental, and additional services. Basic services are performed in five phases: schematic design, design development, construction documents, bidding and negotiation, and construction. Supplemental Services are services that are not included as Basic Services but are identified as the architect’s responsibility at the time the agreement is executed. Additional Services are services that may arise as the project proceeds.
This agreement may be used with a variety of compensation methods, including percentage of the budget for construction cost and stipulated sum. B110–2021 is intended to be used in conjunction with AIA Document A110®–2021, Standard Form of Agreement Between Owner and Contractor for a Custom Residential Project, which contains internal general conditions. A110-2021 is referenced in B110.
Date. The date represents the date the Agreement becomes effective. It may be the date that an oral agreement was reached, the date the Agreement was originally submitted to the other party, the date authorizing action was taken, or the date of actual execution. Professional services should not be performed prior to the effective date of the Agreement.
Parties. Parties to this Agreement should be identified using the full legal name under which the Agreement is to be executed, including a designation of the legal status of both parties (sole proprietorship, partnership, joint venture, unincorporated association, limited partnership or corporation [general, limited liability, close or professional], etc.). Where appropriate, a copy of the resolution authorizing the individual to act on behalf of the firm or entity should be attached.
Project. The proposed Project should be described in sufficient detail to identify (1) the official name or title of the facility, (2) the location of the site, if known, (3) the proposed building usage, and (4) the size, capacity or scope of the Project, if known.
Article 1 – Initial Information
§ 1.1 Initial Information is provided in Section 1.1. The parties should take care to be as explicit and detailed as possible with respect to the relevant Initial Information.
§ 1.1.4 The parties must set forth the Owner’s anticipated dates for construction commencement and Substantial Completion as those dates are to be incorporated into the Architect’s initial schedule for the Architect’s services, and they determine at which point the Architect will provide certain services as Additional Services.
§ 1.1.6 The Owner may have an anticipated Sustainable Objective for the Project, such as obtaining a LEED certification. If so, the Sustainable Objective should be identified and described here.
§ 1.1.9 The AIA publishes standard form Owner-Consultant Agreements, including C103™–2015, Standard Form of Agreement Between Owner and Consultant without a Predefined Scope of Consultant’s Services, which sets the terms and conditions governing the relationship between the Owner and its Consultant. C103–2015 does not include a scope of services and must be paired with another document providing a description of the required services. The AIA publishes two consultant’s scope of services documents, AIA Documents C201™–2015, Standard Form of Consultant’s Services: Land Survey and C202™–2015, Standard Form of Consultant’s Services: Geotechnical Engineering.
§ 1.1.13 Statutory and Other Requirements. The fill points in this section provide the parties with the opportunity to insert any state or local jurisdictional requirements for residential construction. The parties should check on whether any such requirements apply to the project.
§ 18.104.22.168 In some jurisdictions, state or local law may require the inclusion of specific architect’s lien notification or related requirements for residential projects. Insert any such statutorily required language and information in this section.
Article 2 – Architect’s Responsibilities
§ 2.5 The types and limits of the architect’s insurance coverages should be inserted in this section.
Article 4 – Supplemental and Additional Services
§ 4.1.1 The parties should complete the table contained in Section 4.1.1 prior to executing the Agreement. For each Supplemental Service listed, the parties should indicate the party responsible for providing the service in the appropriate column. The AIA publishes standard form scopes of services documents for a number of the Supplemental Services listed in Section 4.1.1, which can be used to describe the Architect’s responsibilities for the identified Supplemental Service. The Architect is not responsible for any listed Supplemental Service unless specifically so designated in the Responsibility column of the table.
§ 22.214.171.124 Conformed documents for construction (commonly identified as “Issued For Construction” documents) are the Construction Documents modified to include any addenda issued during the bidding or negotiation process and accepted alternates.
§ 126.96.36.199 As-designed record drawings are the record of everything the Architect designed for the Project and include the original Construction Documents plus all addenda, Architect’s Supplemental Instructions, Change Orders, Construction Change Directives, and minor changes in the work
§ 188.8.131.52 As-constructed record drawings (commonly called “As-builts”) are the record of the Project as constructed based on information the Contractor provides to the Owner under the contract for construction. Because the As-constructed Record Drawings will be based on the Contractor’s mark-ups, the Architect is not responsible for the accuracy or completeness of the As-constructed Record Drawings.
§ 184.108.40.206 This Section provides space for the parties to provide a detailed description of the Architect’s Supplemental Services identified in Section 4.1.1. Alternatively, the parties can identify and reference an exhibit in this section that provides the detailed description of the Architect’s Supplemental Services. The AIA publishes a number of Standard Form of Architect’s Services documents that can be used as exhibits for this purpose.
§ 220.127.116.11 This Section provides space for the parties to provide a detailed description of the Owner’s Supplemental Services identified in Section 4.1.1. Alternatively, the parties can identify and reference an exhibit in this section that provides the detailed description of the Owner’s Supplemental Services.
§ 4.2.3 Insert an agreed-upon number in each of the spaces provided.
§ 4.2.5 Insert the number of months beyond which the Architect shall be entitled to compensation as Additional Services.
Article 8 – Claims and Disputes
§ 8.2.4 Select from three choices of binding dispute resolution: (1) arbitration, (2) litigation, or (3) another method that the parties must identify. Other types of dispute resolution include a dispute resolution board or a mini-trial. For additional information about other methods of dispute resolution, refer to The Construction Industry’s Guide to Dispute Avoidance and Resolution or visit adr.org for more information.
Article 11 – Compensation
§ 11.1 Insert the basis of compensation for the Architect’s Basic Services.
If the parties do not intend to utilize a stipulated sum method or percentage basis method, Section 11.1 allows the parties to identify another basis of compensation. There are a number of other methods for computing compensation for architectural services. Four of these methods are time-based, reflecting in different ways the time spent by the Architect on the Project:
Multiple of Direct Salary Expense, in which direct salaries of designated personnel are multiplied by a factor representing benefits, overhead, and profit.
Multiple of Direct Personnel Expense, in which the salaries plus benefits of designated personnel are multiplied by a factor representing overhead and profit.
Professional Fee Plus Expenses, in which the salaries, benefits, and overhead of designated personnel are the expense and the fee may be a multiplier, percentage, or lump sum representing profit.
Hourly Billing Rates, in which salaries, benefits, overhead, and profit are included in the rate for designated personnel.
Other methods, while they may be indirectly related to time expended on the Project, do not use time as a factor in the calculation:
Multiple of Consultants’ Billing, in which Consultants’ bills are multiplied by a factor representing the Architect’s administrative costs, overhead, and profit.
Square Footage, in which the square footage of the structure is multiplied by a pricing factor.
Unit Cost, in which the number of certain units such as rooms, acres, etc., is multiplied by a pricing factor.
Royalty, in which compensation is a share in the Owner’s income or profit derived from the built facility.
The AIA makes no recommendation as to the appropriateness of any of these methods of compensation on a particular project, nor does the AIA suggests that the foregoing list includes all methods that are possible, practical, or in actual use. The use of any of the compensation methods described above, singly or in combination with other methods, is a business decision for the Architect and the Owner. Further, the AIA makes no recommendations and has no guidelines or schedules that specify the amount of compensation an architect should be paid.
Sample language is provided below for several of the most widely used methods of compensation.
If a Multiple of Direct Salary Expense is used, include multipliers using words and numerals in the following insert:
Compensation for services rendered by principals and employees shall be based on a multiple of ________ (__) times Direct Salary Expense, which shall be defined as the direct salaries of the Architect’s personnel engaged on the Project excluding any costs of mandatory or customary contributions and benefits. Compensation for services rendered by Consultants shall be based on a multiple of ________ (__) times the amounts billed by Consultants.
If a Multiple of Direct Personnel Expense is used, include multipliers using words and numerals in the following insert:
Compensation for services rendered by principals and employees shall be based on a multiple of ________ (__) times Direct Personnel Expense. Compensation for services rendered by Consultants shall be based on a multiple of ________ (__) times the amounts billed by Consultants.
If a Professional Fee Plus Expenses is to be used, include the dollar figure and the appropriate multipliers (using words and numerals) in the following insert:
Compensation shall be a Fixed Fee of ________ ($__) plus a multiple of ________ (__) times Direct Personnel Expense. Compensation for services rendered by Consultants shall be based on a multiple of ________ (__) times the amounts billed by Consultants.
Alternatively, the fee (representing profit) may be calculated as a multiplier or percentage.
If Hourly Billing Rates are used, include the cumulative amount for salary, benefits, overhead, and profit to fix each rate using words and numerals in the following insert:
Compensation for services rendered by Principals and employees shall be based upon the hourly billing rates set forth below:
- Principals’ time at the fixed rate of ________ ($__) per hour. For the purposes of this Agreement, the Principals are: (List Principals, such as owners, partners, corporate officers, and participating associates.)
- Supervisory time at the fixed rate of ________ ($__) per hour. For the purposes of this Agreement, supervisory personnel includes: (List managerial personnel by name or job title, such as general manager, department head, or project manager.)
- Technical Level I time at the fixed rate of ________ ($__) per hour. For the purposes of this Agreement, Technical Level I personnel include: (List personnel by name or job title who are highly skilled specialists, such as job captains, senior designers, senior drafters, senior planners, senior specifiers, or senior construction administrators.)
- Technical Level II time at the fixed rate of ________ ($__) per hour. For the purposes of this Agreement, Technical Level II personnel include: (List personnel by name or job title who hold intermediate-level positions relative to Technical Level I, such as professionals awaiting licensure and managers of clerical staff.)
- Technical Level III and clerical personnel time at the fixed rate of ________ ($__) per hour. For the purposes of this Agreement, Technical Level III and clerical personnel include: (List personnel by name or job title who occupy junior-level positions, such as word processor or office assistant.)
- Compensation for services rendered by Consultants shall be based on a multiple of ________ (__) times the amounts billed by Consultants.
Compensation shall be a stipulated sum of ________ ($__).
No sample language is provided for compensation based on square footage, unit cost or royalty. Parties choosing one or more of these methods should craft their own language based on the particulars of the Project.
