AIA A141 explained for ARE 5.0
A plain-language breakdown of the Owner-Design Builder Agreement — what it covers, how design-build delivery works, and why it matters for your exam.
What is AIA A141?
The AIA A141 — formally titled Standard Form of Agreement Between Owner and Design-Builder — is the contract used when an owner engages a single entity to provide both design and construction services under one agreement. The 2014 edition is the version tested on the ARE 5.0.
In a traditional project, the owner has two separate contracts — one with the architect (B101) and one with the contractor (A101). In design-build, A141 replaces the traditional separate owner-architect and owner-contractor contract structure. The design-builder is responsible for delivering the complete project — design and construction — to the owner under a single contract. This fundamentally changes the architect’s role, the owner’s risk exposure, and the project delivery process.
Why A141 appears on PjM and PcM
A141 is tested on Project Management and Practice Management because design-build delivery affects how projects are managed, how the architect’s role is defined, and how risk is allocated between the parties.
PjM
Project Management
Covers how design-build projects are structured and managed, how the design-builder coordinates design and construction simultaneously, and how owner changes are handled under a single contract.
PcM
Practice Management
Covers how design-build affects the architect’s professional role and liability, how firms position themselves in design-build teams, and the business and risk implications of the delivery method.
How design-build works
Understanding the design-build delivery method is essential for answering A141 questions on the ARE:
Single point of responsibility
One contract, one entity
The owner contracts with a single design-builder who is responsible for both design and construction. If something goes wrong — whether it is a design error or a construction defect — the owner has only one party to hold accountable. This is the primary advantage of design-build for the owner.
The architect’s role in design-build
Employed by or partnered with the design-builder
In design-build, the architect typically works for the design-builder — not the owner. The architect may be a subcontractor to a general contractor who leads the design-build team, or the architect’s firm may lead the team and self-perform or subcontract construction. Either way, the architect does not have an independent contract with the owner under A141.
Owner’s representative
No independent architect
Because the architect works for the design-builder in design-build, the owner loses the independent advocate they would have in a traditional delivery method. The architect cannot serve as an impartial decision-maker between the owner and design-builder the way they would between owner and contractor under A201.
Design-build vs. traditional delivery
Speed vs. control
Design-build allows design and construction to overlap — the design-builder can begin construction on early packages while design continues on later phases. This accelerates the schedule but reduces the owner’s ability to review and control design decisions independently.
Key provisions to know for the exam
Owner’s criteria
The design and performance standard
A141 §1.1 requires the owner to provide Owner’s Criteria — establishing the program, design requirements, performance expectations, budget, and milestones the design-builder must satisfy. These criteria define what the design-builder is obligated to deliver and serve as the basis for evaluating the design-builder’s work.
Contract sum
Often a lump sum or GMP
A141 can be structured as a lump sum, cost-plus with a guaranteed maximum price, or other basis. The contract sum and payment terms are established in the agreement. Unlike traditional delivery, the design-builder bears the risk of both design and construction cost overruns.
Design-builder’s responsibilities
Responsible for design and construction obligations
The design-builder is responsible for the Work and for the acts and omissions of its architect, consultants, contractors, and subcontractors. The owner’s contract is with the design-builder — if the architect working for the design-builder makes a design error, the design-builder is the party liable to the owner.
Changes in the work
Change Orders and Change Directives
Under A141 §6.1–§6.3, changes to the work may be made by Change Order (agreed by both owner and design-builder) or by Change Directive (issued by the owner when agreement on cost or time cannot be reached). Because there is no independent architect acting as administrator, the owner has less independent oversight of scope and cost impacts compared to traditional delivery.
Common exam traps
- In design-build, the architect typically works for the design-builder — not the owner.
- A141 replaces the traditional separate owner-architect and owner-contractor contract structure — there is no independent owner-architect agreement in a true design-build project.
- The owner loses the independent architect advocate they would have in traditional delivery.
- The design-builder is responsible for the Work and for the acts and omissions of its design team and contractors — the owner has a single point of accountability.
- Design-build accelerates schedules by overlapping design and construction phases.
- Owner’s Criteria in A141 establish the program, design requirements, performance expectations, budget, and milestones the design-builder must satisfy.
- Changes may be made by Change Order (with agreement) or Change Directive (owner-issued when agreement cannot be reached) — per A141 §6.1–§6.3.
Exam tip
When an ARE question asks about design-build delivery, focus on three things: who the architect works for (the design-builder, not the owner), what the owner gains (single point of responsibility, faster schedule), and what the owner gives up (independent design oversight, ability to hold architect and contractor separately accountable). These trade-offs are the core of how design-build is tested on PjM and PcM.
How A141 relates to other AIA contracts
A141 is one of several project delivery agreements in the AIA family. A101 covers traditional stipulated sum delivery, A133 covers CM at-risk with a GMP, and A141 covers design-build. Understanding the differences between these three delivery methods — and which AIA contract governs each — is one of the most important comparative skills tested across PjM and PcM. Each method allocates risk differently between the owner, designer, and builder, and each changes the architect’s role in a fundamental way.
