A201 Architect's CA Role, Subcontractors, and Separate Contractors (Articles 4-6)

Covers the architect's construction administration duties under AIA A201-2017 Articles 4 through 6, including site visits, submittal review, interpretations, reporting obligations, subcontractor administration, and the owner's right to engage separate contractors.

ARE · Project Management

Overview

During construction, the architect's role shifts dramatically from designer to contract administrator. AIA A201-2017 dedicates three full articles to defining this shift, and the ARE expects you to know where those boundaries sit.

Article 4 spells out what the architect does (and does not do) during construction administration. You'll visit the site, review submittals, interpret the contract documents, and report deviations to the owner. But you won't supervise the contractor, direct their means and methods, or take charge of job site safety. That distinction matters. Getting it wrong on the exam costs points; getting it wrong in practice invites lawsuits.

Article 5 addresses subcontractors. The contractor selects them, but the owner and architect have a right to object on reasonable grounds. The contractor remains responsible for subcontractor performance and must submit a list of proposed subcontractors after contract award.

Article 6 deals with separate contractors, those hired directly by the owner to perform work on the same project. When multiple prime contracts exist, coordination responsibilities multiply. The owner must manage the interfaces between these contractors, with the architect's help.

These three articles together define a three-sided relationship: architect, contractor (with subs), and owner (potentially with separate contractors). For the PjM exam, you need to know who communicates with whom, who has authority over what, and where the liability lines fall.

Essential

These three articles form the backbone of how construction gets managed under a standard AIA contract. Let's break them down piece by piece. ## Article 4: The Architect ### General Authority and Limits The architect during construction administration is not the owner's general agent. Read that again. The architect can only act on the owner's behalf to the extent the contract documents allow. This is a huge exam concept. The architect has specific, limited authority, not blanket power to run the project. Changing the architect's duties or authority requires written consent from all three parties: owner, contractor, and architect. None of them can unilaterally expand or shrink the architect's role. The AIA ethical code requires the architect to act with impartiality when administering the contract. This dual obligation, faithful to the owner's interests while fair to the contractor, creates a quasi-judicial role during disputes and interpretations.

Professional

Consider a mid-size architecture firm providing CA services on a $12 million mixed-use project. The owner has also engaged a separate contractor for the elevator installation. Three weeks after the general contractor begins work, the elevator subcontractor and the general contractor clash over access to the shaft. The owner calls the architect, expecting a resolution. Where does the architect's authority begin and end? Under Article 4, the architect administers the contract between the owner and the general contractor. The architect can interpret the contract documents and decide disputes between those two parties. But the separate elevator contractor has a direct contract with the owner, not the general contractor. That separate contract falls under Article 6. The architect may assist the owner in coordinating the work, but the coordination responsibility sits with the owner.

TLDR

Article 4 defines the architect's CA role: site visits, submittal review, interpretations, reporting deviations, and determining completion. The architect is NOT the owner's general agent.
The architect observes work; does not inspect it. General familiarity, not exhaustive monitoring.
Contractor owns means, methods, techniques, sequences, procedures, and safety. Full stop.
Under Section 4.2.3, the architect must report known deviations from documents and schedule, plus observed defects.
Submittals (shop drawings, product data, samples) prove the contractor's proposed conformance to the design concept. No work proceeds without approved submittals.
The architect interprets the contract documents impartially; protected from liability for good-faith decisions unless breaching the contract or standard of care.
Article 5: contractor selects subs; owner/architect can object on reasonable grounds. Rejected capable sub triggers a change order.
Article 6: owner can hire separate contractors. Owner coordinates them with the prime contractor. Architect assists but doesn't assume that coordination responsibility.
Communications with subcontractors go through the contractor. Communications with separate contractors go through the owner.
15 claims per 100 projects for architects. Most originate during construction. Document everything.

ELI5

Think of a construction project like a school play. The architect wrote the script (the design), and now it's time for the actors (the contractor and subcontractors) to perform it. During the performance, the architect sits in the audience and watches. Not every second of every rehearsal, but enough times to know whether the play is going the way it's supposed to. If something looks off, the architect tells the director (the owner). That's what Article 4 is about. The architect does NOT go backstage and tell the stagehands how to move the scenery. That's the contractor's job. How to build things, what tools to use, how to keep everyone safe backstage? All the contractor's responsibility. The architect only cares about whether the final performance matches the script. Now, the lead actors hired some extras (subcontractors) to fill out the cast.
