Under AIA Document A201–2017, the Initial Decision Maker (IDM) reviews covered claims and issues an initial decision; the Architect fills that role by default unless the owner-contractor agreement names someone else. The decision is one stage in the contract’s claims process, not automatically a final arbitration award or court judgment. The project’s signed agreement, incorporated general conditions, and amendments determine who serves as IDM and what happens next.
What is the Initial Decision Maker in an AIA contract?
The Initial Decision Maker is the person or entity assigned by the contract to make an initial decision on covered claims. In A201–2017, the Architect is the default, unless the agreement indicates otherwise. AIA’s A201–2017 General Conditions state in §15.2.1: “The Architect will serve as the Initial Decision Maker, unless otherwise indicated in the Agreement.”

The role is defined by the contract, not by a universal rule that every architect must decide every construction dispute. AIA’s instructions for the owner-contractor agreement explain that the parties may identify an IDM in the agreement. That means the executed project documents matter more than an assumption based on a standard form or on the Architect’s ordinary project responsibilities.
The IDM’s job is an initial step in the claims process. A201–2017 describes the IDM reviewing a covered claim and issuing a written decision with reasons, or indicating that the IDM cannot resolve it. If applicable, the decision also addresses a change in Contract Sum or Contract Time. AIA’s summary of A201–2017 places that decision within a process that can continue to mediation and binding dispute resolution.

Who is the IDM under AIA A201?
For A201–2017, the Architect serves by default if the owner-contractor agreement does not indicate another IDM. But that answer is only a starting point: check the signed agreement and amendments to see whether the parties selected someone else or changed the applicable procedure.
The agreement is where the parties can identify an IDM. AIA’s A101–2017 instructions explain that the owner and contractor may identify an Initial Decision Maker to render initial decisions on claims between them. This is distinct from deciding how a dispute will be resolved if it proceeds beyond the initial stage. AIA describes arbitration, litigation, or another stated method as choices for binding dispute resolution.

Can the Architect decide a contractor’s claim?
Under A201–2017, the Architect can serve as IDM and make an initial decision on a covered claim when the agreement has not designated someone else. That does not mean every disagreement automatically goes to the Architect, or that the Architect’s decision resolves the dispute conclusively.

First determine whether the issue is a “Claim” covered by the executed contract and whether applicable procedural conditions have been met. A201–2017 §15.2 contains the claims process, but the specific project agreement and amendments may affect how it applies. The available standard-form materials do not establish that every project dispute is subject to an identical route, so avoid treating the IDM as a general-purpose decision-maker for any disagreement arising on site.
Where the Architect is also serving as IDM, the person’s project involvement or connection to the disputed issue may be a practical concern for the parties to raise with counsel. The cited AIA materials establish the contractual role, but do not determine the neutrality implications or legal effect in any particular project. Do not assume either that involvement automatically disqualifies the Architect or that it cannot matter; the executed wording, applicable law, and facts are important.

For a covered claim under A201–2017, the IDM considers the matter and issues an initial written decision stating reasons, or indicates that the IDM is unable to resolve the claim. Where relevant, the decision gives notice of a change to the Contract Sum or Contract Time. The agreement’s wording controls the applicable requirements and any modified steps.
- Identify the governing documents. Locate the signed owner-contractor agreement, incorporated general conditions, amendments, and any other contract documents that address claims. Confirm the edition and whether the form was modified.
- Find the IDM designation. Check whether the agreement names an IDM other than the Architect. If no different person is indicated and A201–2017 applies without a relevant amendment, the Architect is the default under §15.2.1.
- Check whether the issue follows the claims procedure. Read the applicable provisions for claim scope, notice, and procedure rather than assuming every project dispute automatically goes to the IDM. The standard-form materials do not supply one project-specific answer for every contract.
- Follow the contract’s applicable process. The A201–2017 framework calls for an initial written decision with reasons, or an indication that the IDM cannot resolve the claim. Do not substitute an assumed deadline or submission method for what the signed contract says.
- Track any stated effect on time or money. If the decision changes Contract Sum or Contract Time, the form calls for notice of that change. Record what the decision says and compare it with the contract’s terms.
- Review the next dispute-resolution stage. A201–2017 describes mediation and binding dispute resolution as later steps. Check the agreement for the selected binding method and any amendments before deciding what to do next.
This sequence is a way to read the contract, not a substitute for project-specific legal advice. An active claim can be affected by notice requirements, amendments, governing law, and facts that are not captured in a general explanation of the standard form.

Is an AIA initial decision final and binding?
An IDM decision is an initial decision, not automatically an arbitration award or court judgment. Under A201–2017, the contract provides for later dispute-resolution steps, including mediation and binding dispute resolution; the parties’ agreement identifies the binding method.
AIA’s A101–2017 instructions identify arbitration, litigation, or another stated method as possible choices for binding dispute resolution. The choice of IDM and the choice of later binding method are related contract decisions, but they are not the same decision. Naming an IDM does not by itself tell you which binding method applies.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
AIA’s summary also describes the IDM decision as operating within a process that preserves the parties’ ability to pursue later dispute resolution. Accordingly, do not treat an initial decision as the end of the matter without checking the contract and any applicable amendments. Nor should a party assume that a later step is available in a particular way or on a particular timetable without reading the governing documents.
How should the parties evaluate a proposed IDM?
If the agreement has not yet been finalized, the parties can consider whether to name the Architect or another agreed person or entity. The source materials establish that the agreement may identify an IDM; they do not rank alternatives or guarantee that one choice is more neutral or effective in every project.

- Who is named? Confirm the exact person or entity and how the agreement identifies the role. Do not rely on an informal assumption that the Architect will serve.
- What is the person’s project role? Consider whether the proposed IDM has project involvement or an interest connected to likely disputed issues. This is a question to raise with counsel, not proof of a conflict or a prediction about the legal outcome.
- What claims and procedures are covered? Review the agreement and general conditions for claim scope, notice requirements, response periods, and amendments. Do not fill gaps in the documents with assumed standard practice.
- What happens after the initial decision? Separately identify the contract’s mediation and binding dispute-resolution provisions, including the stated method. The initial decision-maker designation does not answer this on its own.
For a project already underway, the signed contract governs the analysis. A proposed alternative may not be the person actually designated, and amendments or applicable law may affect what the parties can change or how a clause operates. Ask a construction attorney to assess those project-specific questions before acting on an assumption about the IDM’s authority or neutrality.
What should you check in the project contract?
Before sending a claim or relying on an initial decision, assemble the documents that establish the project’s actual procedure. A standard-form preview or general summary can explain the framework, but it cannot confirm what a particular project signed.
- The executed owner-contractor agreement and the edition of the form it uses.
- The incorporated general conditions, including whether A201–2017 applies.
- Amendments, supplementary conditions, or other modifications to the claims provisions.
- The agreement’s IDM designation, if any, and the language that controls if it differs from the Architect default.
- The provisions that apply to the specific claim, including notice and procedural conditions.
- The later dispute-resolution terms: mediation and the chosen binding method, such as arbitration, litigation, or another stated method.
- Any language addressing changes to Contract Sum or Contract Time and how a decision is communicated.
When a live dispute is involved, preserve the relevant project records and get advice based on the full contract and applicable law.

Even when a contract incorporates A201–2017, the agreement and its modifications are central to applying §15.2. The standard text tells you the default role and general sequence; the executed documents determine the project-specific designation and procedure. If there is a disagreement about how the clause applies, a construction attorney can review the contract, governing law, and facts together.
Frequently Asked Questions
Does the IDM handle claims between the owner and contractor only?
AIA’s A101–2017 instructions describe the agreement’s IDM designation as covering claims arising between the owner and contractor. Whether a particular dispute falls within the contractual claims process depends on the project documents and the issue involved.
Where in A201–2017 is the Initial Decision Maker described?
The IDM provisions are in §15.2, including the default Architect designation in §15.2.1. Use the edition incorporated into the project contract, since a different edition or amendment may change the applicable wording.
Does naming an IDM also choose arbitration or litigation?
No. The IDM designation identifies who makes the initial decision; the agreement’s binding dispute-resolution terms identify the later method, which AIA’s A101–2017 instructions say may be arbitration, litigation, or another stated method.
Can an IDM’s decision change the contract price or time?
A201–2017 provides for notice of a change in Contract Sum or Contract Time when applicable. Whether a particular claim results in such a change depends on the decision and the governing contract.
