1.1 Project Delivery Methods & Construction Administration Roles

CE exam facts checked October 16, 2026

This is independent preparation by OpenExamPrep. NCARB's Construction & Evaluation division has 75 items: 68 scored and 7 unscored pretest items, 3 hours of testing, an optional 30-minute break, and a 3-hour-40-minute appointment including introductory and exit screens. The October 2026 Guidelines list up to seven case studies and up to 16 case-study items; do not plan around an older promise of exactly two cases. Each case has one or two resources after the April 2026 format update.

The current fee is $263 per division or retake. Schedule through your NCARB Record with PSI, after your jurisdiction grants eligibility. A failed division may be retaken after 60 days, with at most three attempts in a 12-month period. NCARB publishes a CE passing range of 58–66% of scored items, depending on exam form; the CE 2025 pass rate was 61% across first-time and repeat candidates, which is a different statistic. Passed divisions follow NCARB's exam-version-based score validity policy, replacing the five-year rolling clock.

The four blueprint sections are Preconstruction Activities (17–23%), Construction Observation (32–38%), Administrative Procedures & Protocols (32–38%), and Project Closeout & Evaluation (7–13%). Use NCARB's free practice exam to learn the interface, resource viewer, and break restrictions. Review answered items before a break because previously viewed items become locked afterward.

1.1 Project Delivery Methods & Construction Administration Roles

Project delivery methods define the contractual structure, operational relationships, risk allocation, and communication channels among the owner, architect, and contractor. For the Construction & Evaluation (CE) division of the ARE 5.0, you must evaluate how an architect's Construction Administration (CA) responsibilities and legal vulnerabilities shift across different delivery methods.

Every project delivery method represents a specific balance among three competing project constraints: budget (cost), schedule (time), and scope/quality. The method selected dictates when the contractor enters the project, who holds contractual privity with whom, who warrants the sufficiency of the construction documents, and who holds ultimate authority over payment certifications, submittals, and site rejections.

Traditional Design-Bid-Build (DBB)

Design-Bid-Build (DBB) remains the baseline traditional delivery method against which all other methods are compared. In DBB, project execution follows a strictly linear, sequential progression:

1. Design Phase: The owner contracts separately with the architect under AIA Document B101-2017 (Standard Form of Agreement Between Owner and Architect) to prepare complete drawings and specifications.
2. Bidding/Negotiation Phase: Fully developed Construction Documents (CDs) are released to prospective general contractors, who submit competitive lump-sum (stipulated sum) bids.
3. Construction Phase: The owner awards the contract to the lowest responsive and responsible bidder under AIA Document A101-2017, governed administratively by AIA Document A201-2017 (General Conditions of the Contract for Construction).

Contractual Privity and Communication Channels

Under DBB, there are two separate prime contracts: Owner-Architect and Owner-Contractor. Crucially, no contractual privity exists between the architect and the contractor. The architect serves as the owner's professional agent and representative during construction.

Under A201 § 4.2.4, the owner and contractor include the architect in communications affecting the architect's services or professional responsibilities, and the owner promptly reports the substance of other direct project communications. Direct owner-contractor communication is permitted. Similarly, communications between the architect and subcontractors must flow through the general contractor. Subcontractors hold contracts exclusively with the prime contractor; the architect has no legal standing to direct subcontractor operations.

Risk Allocation and the Spearin Doctrine

DBB carries a distinct legal risk profile established by the landmark Supreme Court decision United States v. Spearin (1918). Under the Spearin Doctrine, the owner impliedly warrants to the contractor that the plans and specifications provided are sufficient for construction. If design defects, omissions, or dimensional conflicts cause contractor delays or cost overruns, the contractor pursues a claim against the owner—not the architect. The owner must pay the contractor for extra work via Change Order and may subsequently attempt to recover damages from the architect under a claim of professional negligence (failure to meet the professional Standard of Care).

Architect's Construction Administration Role in DBB

In DBB, the architect exercises broad, independent CA authority:

• Site Observation: Visits the site at intervals appropriate to the stage of construction to become generally familiar with the progress and determine if the work complies with the contract documents (A201 § 4.2.2).
• Submittal Review: Reviews and takes action on shop drawings, product data, and samples with reasonable promptness for the limited purpose of checking for conformance with design intent (A201 § 4.2.7).
• Payment Certification: Reviews contractor Applications for Payment (AIA G702/G703) and issues Certificates for Payment (A201 § 9.4).
• Rejection of Work: Holds unilateral contractual authority to reject work that does not conform to the contract documents (A201 § 4.2.6).
• Initial Decision Maker (IDM): Serves as the default IDM to render initial determinations on claims between owner and contractor (A201 § 15.2).

Construction Manager as Adviser (CMa) vs. Construction Manager as Constructor (CMAR)

The introduction of a Construction Manager (CM) adds specialized cost estimating, constructability analysis, scheduling, and procurement expertise. However, the CM's role fundamentally diverges depending on whether the CM acts as an Adviser or a Constructor.

Construction Manager as Adviser (CMa)

In the CMa model, the owner retains an independent third-party management consultant who does not construct the building. The CMa family of AIA contracts governs this four-party relationship: AIA Document B132-2019 (Owner-Architect, CMa Edition), AIA Document C132-2019 (Owner-CMa), AIA Document A132-2019 (Owner-Contractor, CMa Edition), and AIA Document A232-2019 (General Conditions, CMa Edition).

Key characteristics of CMa:

• No Financial Stake in Trade Construction: The CMa acts purely as an agent/consultant to the owner and holds no trade subcontracts.
• Multiple or Single Prime: The owner may contract with a single general contractor or multiple prime contractors under the CMa's operational coordination.
• Joint Administrative Authority: The CMa does not replace the architect. Instead, administrative duties are performed jointly:
  • Payment Certification: The contractor submits applications to the CMa. The CMa reviews the application, certifies the amount due, and forwards it to the architect. The architect makes an independent evaluation and issues the final Certificate for Payment. Both the CMa and the architect must sign (A232 § 9.4).
  • Submittals: The CMa receives submittals first, reviews them for coordination, and forwards them to the architect for final approval regarding design intent.
  • Change Orders: CMa Change Orders use G731 and are signed by owner, contractor, construction manager and architect. CMa directives use G733; contractor agreement is not required to direct a change.
  • Rejection of Work: Both the architect and the CMa possess independent authority to reject non-conforming work (A232 § 4.2.8).

Construction Manager as Constructor (CMAR / CMC)

In Construction Manager as Constructor (CMAR)—also designated Construction Manager at Risk (CMR)—the entity serves a dual role across two distinct phases, governed by AIA Document A133-2019 (or A134 without GMP) and AIA Document B133-2019 (Owner-Architect, CMAR Edition):

1. Preconstruction Phase: The CMAR acts as an advisory consultant providing cost estimates, value engineering, constructability reviews, and project scheduling while the architect develops design documents.
2. Construction Phase: The CMAR transitions into the prime general contractor. The CMAR executes an amendment establishing a Guaranteed Maximum Price (GMP) at an agreed design stage and accepts defined overrun risk, subject to contractual adjustments and qualifications. The CMAR holds all trade subcontracts.

Architect's Role in CMAR

Once the GMP is established and construction commences, the architect's CA role resembles traditional DBB under AIA Document A201-2017. However, key operational dynamics shift:

• Collaborative Problem Solving: Because the CMAR participated in preconstruction, fewer constructability RFIs should theoretically arise.
• Cost Transparency: Under cost-plus with a GMP contracts, the architect often participates in reviewing the CMAR's open-book accounting records and trade buyout packages.
• Adversarial Pressure at the GMP: Once the GMP is executed, any scope omissions or design ambiguities become potential flashpoints. The CMAR will argue that ambiguous details exceed the GMP scope, leading to aggressive Change Order requests.

Design-Build (DB): Single-Source Responsibility

In Design-Build (DB), the owner executes a single contract with a single entity—the Design-Builder—who provides both design and construction services under AIA Document A141-2014 (Standard Form of Agreement Between Owner and Design-Builder).

Organizational Structures in Design-Build

The Design-Builder entity can take several structural forms:

• A contractor-led firm that subcontracts the architect via AIA Document B143-2014 (Standard Form of Agreement Between Design-Builder and Architect).
• An architect-led firm that subcontracts the general contractor.
• A joint venture between an architectural firm and a contracting firm.
• A fully integrated, single corporation employing both architects and builders.

Transformation of Architect's Agency and Ethical Duties

Design-Build fundamentally alters the architect's traditional professional stance:

• Loss of Independent Agency: When subcontracted to a contractor-led design-builder under B143, the architect's legal client is the Design-Builder, not the building owner. The architect cannot act as the owner's independent watchdog on site.
• Design responsibility: The design-builder generally accepts responsibility for its design and construction. Owner-furnished design or criteria can change risk allocation; design-build does not categorically eliminate all owner design liability.
• Public Welfare vs. Client Pressure: If the design-builder orders the architect to approve substandard materials or omit details to protect builder profit margins, the architect remains legally and ethically bound by professional licensure laws to protect public health, safety, and welfare. The architect cannot waive building code compliance or life-safety standards to satisfy the contractor-client.
• Owner's Consultant (Bridging): Often, an owner hires an independent architect—termed a Bridging Architect or Criteria Consultant under AIA Document B142-2014—to develop preliminary design criteria (typically through Schematic Design) and provide independent CA oversight on the owner's behalf during construction.

Integrated Project Delivery (IPD): Multi-Party Collaboration

Integrated Project Delivery (IPD) represents the highest level of collaboration, integrating people, systems, business structures, and practices into a process that collaboratively harnesses the talents of all participants. Governed by AIA Document C191-2009 (Standard Form Multi-Party Agreement for IPD), the primary stakeholders—at minimum the Owner, Architect, and Contractor—sign a single, unified contract.

Foundational Principles of IPD

• Early Involvement of Key Participants: Contractor and key specialty trades (MEP, structural) participate from conceptualization.
• Shared Financial Risk and Reward: The team collectively establishes a Target Cost. Compensation typically covers direct costs (open-book), while team profits are pooled into a shared incentive contingency. If the project finishes under target cost, the savings are split among owner, architect, and contractor. If costs exceed the target cost, team profits are decremented or eliminated.
• Project-specific liability provisions: Read the multiparty agreement for any risk-sharing, claim-waiver and dispute provisions. IPD collaboration does not itself eliminate professional duties or all claims.
• Collaborative CA Workflow: Information requests, submittals and change documentation still need defined procedures even when collaboration reduces disputes. Design adjustments occur dynamically using shared, centrally coordinated Building Information Models (BIM).

Multiple Prime (MP): Fast-Tracking Without a General Contractor

In Multiple Prime (MP) delivery, the owner bypasses the general contractor and enters into multiple separate prime contracts directly with individual trade contractors (e.g., General Construction, Steel Erection, Mechanical, Electrical, Plumbing, Roofing). MP is frequently mandated on state and municipal public works projects to stimulate local subcontractor participation.

The Coordination Vacuum and Legal Hazards

Because there is no general contractor holding master operational control:

• No Privity Among Primes: None of the prime trade contractors hold contracts with one another. Contractor A cannot legally direct or issue back-charges against Contractor B.
• Owner Bears the Duty to Coordinate: Under common law, the owner assumes the non-delegable duty to coordinate trade sequencing, jobsite access, staging, and master scheduling. If one prime delays another, the delayed prime files a delay claim directly against the owner.
• Architect Exposure: Unless the owner contracts with a CMa or specifically amends the architect's agreement to provide comprehensive project management services (with commensurate additional compensation), the architect is not responsible for coordinating multiple prime contractors. However, in practice, owners often attempt to push master scheduling and field coordination onto the architect. The architect must strictly adhere to the boundaries of AIA B101 to avoid assuming contractor liability for project delays.
