From Design to Construction: Where Coordination Becomes Critical
Design may define the project—but construction is where decisions are tested. During this phase, questions arise daily. Is the work aligned with the design intent? Should a submittal be approved? Is the contractor entitled to payment?
The answers aren’t improvised—they’re defined by how B101 and A201 work together.
- B101™ – Agreement Between Owner and Architect establishes the architect’s services and responsibilities.
- A201® – General Conditions of the Contract for Construction defines how those responsibilities function during construction.
Together, they create the framework for contract administration.
What B101 and A201 Each Control
Understanding this pairing starts with a simple distinction:
- B101 defines what services the architect provides.
- A201 defines how the project is administered during construction
A201 is often described as the “operating system” of the construction phase, establishing relationships between the owner, contractor, and architect.
A201: The Architect’s Role During Construction
Under A201, the architect plays a central, but carefully defined, role in administering the contract. Key responsibilities include:
- Reviewing submittals. This includes shop drawings, product data, and samples to ensure alignment with design intent (not means and methods).
- Conducting site visits. Observing progress and general conformance, but not supervising construction means or safety.
- Certifying applications for payment. Reviewing contractor pay applications and certifying amounts due to the owner.
- Interpreting contract documents. This includes clarifying drawings and specifications, and resolving inconsistencies.
- Serving as initial decision maker (IDM). The IDM provides initial decisions on claims and acts as a neutral evaluator.
These responsibilities are not optional; they are contractually defined functions under A201.
Why This Pairing Matters
B101 and A201 don’t operate independently; they reinforce each other. B101 defines your scope of services. A201 defines your authority and limitations during construction.
| When aligned | When misaligned |
|---|---|
| Responsibilities are clear | Authority becomes unclear |
| Communication flows through defined channels | Responsibilities may be disputed |
| Decisions are structured and defensible | Risk exposure increases |
A Practical Example: Submittal Review
A contractor submits a shop drawing for review.
- A201 requires the contractor to submit for approval
- The architect reviews for design intent only
- B101 defines that review as part of the architect’s services
If misunderstood, the architect may be expected to verify construction methods. Or the contractor may assume approval shifts responsibility.
The pairing ensures clear expectations, proper allocation of responsibility
Defining Authority and Limits
A201 gives architects authority, but also sets boundaries. This distinction is critical to maintaining proper risk allocation. For example:
- The architect can reject nonconforming work.
- The architect can interpret contract documents.
- But the architect does not control construction means, methods, or safety.
How B101 and A201 Support Dispute Prevention
Many construction disputes arise from misinterpretation of documents, unclear authority, and misaligned expectations. This pairing helps prevent those issues by:
- Establishing a clear decision-making structure
- Defining the architect’s role as a neutral interpreter
- Creating a process for resolving claims (IDM → mediation → beyond)

Connecting to the Larger Contract System
B101 and A201 are just one part of a broader framework. They work alongside:
- C401™ to align consultants.
- E204™ to Integrate sustainability goals.
- Change management documents to control scope.

What This Means for Your Practice
Construction administration is where architects maintain design integrity, facilitate communication, and help manage risk across the project team.
But success depends on more than experience. It depends on a clear contractual structure that B101 and A201 provide when used together.
Strengthen Your Role During Construction
Your responsibilities during construction are defined by the agreements you use. With unlimited access to AIA Contract Documents, you can ensure your contracts are coordinated, current, and aligned. This supports clearer decisions and stronger project outcomes.
