8.1 AIA B101: Initial Information, Standard of Care & Basic Services
Key Takeaways
- Initial Information fixes program, budget, schedule, and delivery method, and a material change to it entitles the architect to an equitable adjustment.
- B101 Article 2 states the standard of care as the skill and care of an architect performing similar services under similar circumstances in the same locality.
- Basic services comprise schematic design, design development, construction documents, bidding or negotiation, and construction administration.
- B101 states quantitative limits on basic services, such as the number of site visits and submittal reviews included, and exceeding them is an additional service.
- Supplemental services are identified and priced at the time of signing, while additional services arise later and require notice and authorization.
The AIA Document B101™–2017 Standard Form of Agreement Between Owner and Architect is the preeminent contract template in United States architectural practice for design-bid-build project delivery. As the prime agreement establishing the legal relationship between the client (Owner) and the design lead (Architect), B101 defines professional scope, compensation, allocation of risks, and ownership of intellectual property. Understanding the specific mechanics of its articles is critical for passing the ARE 5.0 Project Management (PjM) and Practice Management (PcM) divisions.
Article 1: Initial Information and Project Parameters
Article 1 establishes the baseline assumptions upon which the agreement is executed. It defines:
- Project Parameters: The owner's program, physical site characteristics, legal parameters, zoning constraints, and sustainable design objectives.
- Budget and Schedule: The owner's budget for the Cost of the Work, project milestone dates, and the anticipated procurement or bidding method.
- Project Team Representatives: The identification of the owner's authorized representative (who holds legal authority to bind the owner), the architect's designated project manager, and required specialty consultants.
- Reliance Clause: Section 1.2 explicitly provides that the architect is entitled to rely on the accuracy and completeness of all information provided by the owner. If initial information changes materially during project progression, the architect is contractually entitled to adjustments in both project schedule and professional compensation.
Article 2: Standard of Care vs. Uninsurable Guarantees
Section 2.2 defines the legal standard by which the architect's professional performance is evaluated:
"The Architect shall perform its services consistent with the professional skill and care ordinarily provided by architects practicing in the same or similar locality under the same or similar circumstances."
Under common law, architects are judged by professional competence, not perfection. Custom construction involves thousands of variables, and design documents are rarely without minor discrepancies. Crucially, the architect must never agree to contractual warranties, guarantees of perfection, or strict liability clauses inserted by owners.
Professional Liability Insurance (PLI / Errors & Omissions) policies are underwritten strictly to cover common law negligence. PLI policies contain explicit exclusions for contractual liabilities assumed by an architect that exceed the common law standard of care. If an architect warrants that drawings will be "100% error-free" or "strictly compliant with every code," any discrepancy creates an uninsurable breach of contract that the insurer will refuse to defend, exposing the firm to direct personal liability.
Article 3: Scope of Architect's Basic Services
Basic Services under Article 3 comprise the five sequential phases of traditional project delivery:
- Schematic Design (SD): Review the owner's program, site conditions, codes, and laws; evaluate alternative design approaches; prepare schematic drawings (site plan, floor plans, building sections, elevations); and submit a preliminary estimate of the Cost of the Work.
- Design Development (DD): Refine schematic concepts into coordinated systems; establish dimensions, typical construction assemblies, structural systems, and MEP systems; prepare outline specifications; and update the cost estimate.
- Construction Documents (CD): Prepare fully detailed drawings and specifications setting forth requirements for construction, permitting, and bidding; incorporate requirements of governmental authorities; and provide a final pre-bid update to the Cost of the Work estimate.
- Procurement (Bidding or Negotiation): Assist the owner in preparing bidding documents, distribute sets to bidders, maintain bid logs, conduct pre-bid conferences, issue addenda in response to bidder questions, and analyze competitive bids or proposals.
- Construction Phase Services: Administer the contract for construction in accordance with AIA Document A201™–2017 General Conditions. The architect acts as the owner's representative, conducts periodic site visits, reviews contractor submittals and shop drawings, issues payment certificates, evaluates change orders, and conducts inspections to determine Substantial Completion and Final Completion.
Quantitative Limits on Basic Services
To prevent scope creep during construction administration, Section 4.2.3 requires the parties to insert explicit numerical caps into the contract:
- Maximum number of reviews per contractor submittal (typically 2).
- Maximum number of site visits during construction (e.g., bi-weekly, or a fixed total such as 24 visits).
- Maximum number of inspections for Substantial Completion and Final Completion (typically 1 or 2).
If construction delays or poor contractor performance require the architect to exceed these numbers through no fault of their own, the additional visits and reviews are compensated as Additional Services.
Article 4: Supplemental Services vs. Additional Services
AIA B101-2017 establishes a vital conceptual boundary between Supplemental Services and Additional Services:
- Supplemental Services (Section 4.1): Design services identified and negotiated at the time of contract execution. These are enumerated in a comprehensive table where responsibility (Architect, Owner, or Not Provided) and compensation method are established upfront. Common examples include programming, existing facilities surveys, historic preservation, building information modeling (BIM) management, commissioning, tenant-related fit-out design, and LEED certification.
- Additional Services (Section 4.2): Unanticipated services that arise during project execution due to changed circumstances beyond the architect's control. These include:
- Material changes in project scope, size, quality, complexity, budget, or delivery method.
- Enactment of new codes, regulations, or zoning laws after document completion.
- Evaluating an extensive volume of contractor substitution requests or RFIs.
- Services necessitated by contractor default, owner termination, major fire, or catastrophic site casualty.
- Preparation for and attendance at public hearings or dispute resolution proceedings.
The architect must notify the owner in writing promptly upon determining that an Additional Service is required, and must receive written authorization before proceeding.
At the conclusion of the bidding phase for a new community library, the lowest bona fide general contractor bid exceeds the owner's approved budget for the Cost of the Work by 18%. The owner rejects bids and instructs the architect to modify the design documents to bring the project within budget. Under AIA Document B101-2017 Article 6, what is the architect's contractual obligation and compensation right?
