Delivery Method Selection

Why Delivery Method Selection Matters
The choice of project delivery method is one of the earliest and most consequential decisions an owner makes. It determines who holds which contracts, how risk is allocated among the owner, designer, and constructor, when the constructor becomes involved, how the project is priced, and how disputes are likely to arise and be resolved. On the CCM exam, Delivery Method Selection falls under the Contract Administration domain because the method chosen defines the contractual framework the Construction Manager (CM) will administer for the life of the project. A CM who understands delivery methods can advise the owner objectively, structure procurement correctly, and anticipate the administrative demands of each approach. Poor selection leads to misaligned incentives, change-order exposure, schedule slippage, and claims. The CMAA Standards of Practice emphasize that the CM acts as the owner's advisor in this decision, which is why the exam tests it heavily.

What Delivery Method Selection Is
A project delivery method is the overall framework that defines the contractual relationships, roles, responsibilities, and sequencing among the owner, designer, and constructor. It answers the question: who is contractually responsible to whom for design and for construction, and in what sequence?

It is important to distinguish three related but separate concepts that the exam frequently blends together:
1. Delivery Method – the organizational and contractual structure (e.g., Design-Bid-Build, Design-Build, CM at-Risk).
2. Procurement Method – how the owner selects the firms (e.g., low bid, best value, qualifications-based selection, sole source, negotiated).
3. Contract Type / Pricing Method – how the firm is paid (e.g., lump sum, unit price, cost-plus-fee, Guaranteed Maximum Price).
A given delivery method can be paired with different procurement and pricing approaches. For example, CM at-Risk is usually procured on qualifications or best value and priced with a GMP, but it does not have to be.

The Principal Delivery Methods

1. Design-Bid-Build (DBB)
The traditional, linear method. The owner holds two separate contracts: one with the designer and one with the general contractor. Design is 100 percent complete before bidding; the contractor is typically selected by low responsive, responsible bid.
Advantages: well understood, maximum competition, owner retains design control, often required by public procurement law, clear price before construction begins.
Disadvantages: longest overall schedule (no overlap of design and construction), no contractor input during design, adversarial relationships, owner holds the risk of design errors and omissions (Spearin Doctrine), highest change-order exposure.

2. Construction Manager as Agent / Agency CM (CM Agency, often with Multiple Prime)
The owner retains a CM as a fiduciary advisor who does not perform construction work and does not hold trade contracts. The owner holds contracts directly with the designer and with one or multiple prime contractors. The CM manages on the owner's behalf for a fee.
Advantages: CM is independent and loyal solely to the owner; allows fast-tracking through multiple bid packages; owner gains professional management expertise without a markup on construction.
Disadvantages: owner retains most risk (schedule, coordination, cost); owner must have capacity to hold many contracts; no single point of responsibility for construction.

3. Construction Manager at-Risk (CMAR / CM-GC)
The owner holds separate contracts with the designer and the CM. The CM is engaged early during design to provide preconstruction services (constructability, estimating, scheduling, value engineering) and then becomes the constructor, usually under a Guaranteed Maximum Price established when design is sufficiently developed. The CM holds the trade subcontracts.
Advantages: early constructor input, cost certainty through the GMP, ability to fast-track, qualifications-based selection possible, owner keeps design control.
Disadvantages: CM's role shifts from advisor to at-risk contractor, creating a potential conflict of interest after the GMP; GMP negotiations can be contentious; owner still bears design risk between designer and CM.

4. Design-Build (DB)
The owner holds a single contract with one entity responsible for both design and construction. The design-builder may be a single integrated firm, a contractor-led team with a design subconsultant, a designer-led team, or a joint venture.
Advantages: single point of responsibility, shortest schedule, reduced owner exposure to design-error claims, early cost commitment, innovation encouraged.
Disadvantages: owner gives up direct design control, less competition on price, difficult to compare proposals, owner must define requirements thoroughly in a bridging document or performance specification before award. The CM often serves as the owner's representative or criteria consultant in this model.

5. Integrated Project Delivery (IPD)
A multi-party contract among owner, designer, and constructor (and often key trades) with shared risk and reward, pooled contingency, collaborative decision-making, and early involvement of all parties. Frequently supported by BIM and lean practices.
Advantages: alignment of incentives, reduced waste, high collaboration.
Disadvantages: requires a sophisticated owner, trust, and legal frameworks that many public owners cannot use.

6. Design-Build-Operate-Maintain, Public-Private Partnerships (P3), and Variants
Extended methods in which the private partner also finances, operates, and/or maintains the facility over a concession period. These shift lifecycle and financing risk to the private sector in exchange for long-term payments or revenue rights.

7. Multiple Prime Contracting
The owner contracts directly with several trade contractors (mechanical, electrical, general, etc.) instead of one general contractor. Required in some states by law. Usually managed with an Agency CM. Eliminates the general contractor markup but puts coordination risk on the owner.

How Delivery Method Selection Works
Selection is a structured analysis, not a default. The CM leads or facilitates the process, typically in the pre-design phase, using the following steps:

Step 1 – Define owner goals and constraints. Determine the owner's priorities among schedule, budget certainty, quality, risk tolerance, design control, and operational needs. Identify legal constraints (public procurement statutes, funding source requirements), owner staff capability, and political or stakeholder factors.

Step 2 – Assess project characteristics. Consider size, complexity, technical uncertainty, site conditions, phasing, need for occupied operations, and the maturity of the program definition.

Step 3 – Evaluate market conditions. Availability of qualified design-builders or CMAR firms, bidding climate, labor market, and whether subcontractor interest will support the chosen approach.

Step 4 – Analyze risk allocation. Each method places risk differently. The guiding principle tested on the exam: risk should be allocated to the party best able to manage and control it. Shifting risk to a party that cannot control it simply raises price or invites claims.

Step 5 – Compare alternatives. Use a weighted-criteria matrix or similar decision tool to score each method against the owner's priorities. Document the rationale.

Step 6 – Select the compatible procurement and contract type. Once the delivery method is chosen, select the procurement approach (low bid, best value, QBS, negotiated) and pricing structure (lump sum, GMP, cost-plus, unit price) that reinforce the owner's objectives.

Step 7 – Document and implement. Prepare the delivery strategy, procurement schedule, and contract documents reflecting the selected method. The CM then administers contracts consistently with that structure.

Key Selection Factors Summarized
- Schedule urgency favors Design-Build, CMAR, or Agency CM with fast-tracking over DBB.
- Need for early cost certainty favors Design-Build or CMAR with GMP.
- Desire for maximum owner design control favors DBB, Agency CM, or CMAR over Design-Build.
- Owner with limited staff favors Design-Build or CMAR (fewer contracts to manage) over Multiple Prime.
- Statutory low-bid requirement often forces DBB unless enabling legislation permits alternatives.
- Complex or uncertain scope favors methods with early constructor involvement and flexible pricing (CMAR, IPD, cost-plus).
- Desire to minimize owner liability for design errors favors Design-Build.
- Desire for an independent advisor with no financial stake in construction favors Agency CM.

The CM's Role in the Decision
Under the CMAA Standards of Practice, the CM provides objective, professional advice to the owner on delivery method selection, procurement strategy, and contract type. The CM does not impose a method; the owner makes the decision. The CM must disclose any conflict of interest, such as a desire to later serve as CM at-Risk on the same project. The CM also ensures the Project Management Plan and Project Procedures Manual reflect the selected method and that all later contract administration activities (submittals, changes, payments, claims) align with the contractual relationships created.

How to Answer Exam Questions on Delivery Method Selection
CCM questions on this topic are scenario-based. They describe an owner's situation and ask which method is most appropriate, what risk the owner retains, or what the CM should recommend. Use this approach:

1. Identify the owner's dominant priority. Read for signal words: fastest, cost certainty, control over design, single point of responsibility, limited staff, public agency, lowest price, complex, undefined scope. The dominant priority points to the method.
2. Identify the constraint. If the scenario says the agency must award to the lowest responsive bidder, eliminate methods that depend on qualifications-based selection unless the question says enabling legislation exists.
3. Map risk to the right party. Ask who controls the risk in question. If the question concerns design-error risk, remember that in DBB and CMAR the owner warrants the design to the contractor; in Design-Build the design-builder owns it.
4. Separate delivery method from procurement and pricing. If the answer choices mix GMP, best value, and Design-Build, recognize which category the question is actually asking about.
5. Think like an owner's advisor. The correct answer is the one that best serves the owner's stated objectives, not the one that benefits the CM or contractor.
6. Eliminate absolutes. Choices stating a method is always fastest, cheapest, or best are usually wrong; the exam rewards recognition of trade-offs.

Exam Tips: Answering Questions on Delivery Method Selection
- Know the contract count. DBB and CMAR: owner holds two contracts. Design-Build: one contract. Agency CM: owner holds the designer, CM, and contractor(s) contracts. Multiple Prime: owner holds many. Questions often hinge on who holds the subcontracts.
- Know when the constructor enters. DBB: after design completion. CMAR, DB, IPD: during design. Early involvement equals constructability input and fast-track capability.
- GMP is a pricing tool, not a delivery method. It is most associated with CMAR but can be used with Design-Build or cost-plus contracts. Do not pick GMP when the question asks for a delivery method.
- Agency CM holds no construction risk and does no construction. If a question asks which method keeps the CM fully independent and fiduciary to the owner, the answer is Agency CM.
- CMAR converts from advisor to contractor. Expect questions about the conflict of interest that arises when the GMP is set and about how the CM's duty shifts.
- Design-Build gives up owner design control but gains single-point responsibility and schedule compression. Watch for scenarios where the owner demands detailed design oversight; Design-Build would be a poor fit.
- DBB is the baseline. When a question describes a conventional, fully designed, publicly bid project with no schedule pressure, DBB is the expected answer.
- Fast-tracking is a schedule technique, not a delivery method. It overlaps design and construction and is enabled by CMAR, Agency CM with multiple packages, or Design-Build.
- Public owners face statutory limits. Many questions test whether the CM recognizes that enabling legislation is required for CMAR or Design-Build in public work.
- The CM recommends; the owner decides. Any answer implying the CM unilaterally selects the method or has a financial stake without disclosure is incorrect.
- Selection occurs early. Delivery method should be determined in pre-design or early design, before procurement documents are drafted. Answers placing it after bidding are wrong.
- Use a documented, criteria-based process. If asked how the CM should support the decision, choose the answer describing a structured evaluation of owner objectives, risk, schedule, budget, and market conditions, with documented rationale.
- Watch for the best-fit principle on risk. The correct answer allocates each risk to the party best able to control it, never simply to the contractor or the owner by default.

Quick Reference Table (in text)
DBB – Two owner contracts; sequential; low bid common; longest schedule; owner holds design risk.
Agency CM – CM as fiduciary advisor; owner holds all contracts; fast-track possible; owner retains risk.
CMAR – Two owner contracts; CM gives preconstruction services then builds under GMP; early input and cost certainty.
Design-Build – One owner contract; single point of responsibility; fastest; less owner design control.
IPD – Multi-party agreement; shared risk and reward; high collaboration; requires sophisticated owner.
Multiple Prime – Owner contracts with several trades; no GC markup; coordination risk on owner.
P3 / DBOM – Private partner finances and/or operates; lifecycle risk transferred; long-term agreement.

Final Takeaway
Delivery Method Selection is the foundation of Contract Administration. Master the structure of each method, the risks it allocates, the conditions under which it fits, and the distinction between delivery method, procurement method, and contract type. On the exam, read for the owner's priority and constraints, allocate risk to the party that controls it, and always answer from the perspective of an objective CM advising the owner.
