Quick answer
At a glance
Construction project delivery methods define who designs the work, who prices it, who manages construction, and how risk is allocated. Contractors should review the delivery method before bidding because design-bid-build, design-build, CM at risk, CM agency, and integrated delivery each change document completeness, pricing responsibility, design exposure, schedule involvement, and relationship strategy.
AI summary
Key takeaways
- Delivery method is a bid strategy issue, not just a contract label.
- The same contractor may need different pricing, staffing, and risk-review steps for each delivery method.
- Read the solicitation, contract form, selection criteria, and design responsibility language before committing pursuit time.
Key takeaways
What you need to know
- Delivery method changes the bid documents, decision-maker, risk allocation, and contractor role.
- Design-bid-build is usually document-driven, while design-build and CM methods require more collaboration and preconstruction judgment.
- Contractors should align pursuit strategy with the owner's procurement method before estimating.

Delivery Method Comparison
| Method | Contractor role | Typical bid review focus |
|---|---|---|
| Design-bid-build | Price completed design documents | Scope completeness, addenda, alternates, unit prices, bonds, deadline rules |
| Design-build | Join or lead a design and construction team | Design responsibility, performance criteria, team qualifications, proposal scope |
| CM at risk | Provide preconstruction input and manage construction risk | Preconstruction scope, cost model, trade buyout, GMP language, open-book requirements |
| CM agency | Provide management services without holding trade risk | Owner contract structure, advisory duties, reporting, procurement support |
| Integrated delivery | Collaborate under shared governance or shared incentives | Multi-party agreement, risk pool, decision rules, required team behavior |
Design-Bid-Build
Design-bid-build separates design and construction. The owner typically contracts with a designer, completes the documents, then solicits bids from contractors.
Contractors should focus on:
- Complete drawings and specifications.
- Addenda and bid form requirements.
- Alternates, allowances, and unit prices.
- Bid bond, insurance, and submission instructions.
- Scope gaps between trades.
- Questions that need a pre-bid RFI.
Use the construction bid review checklist when the solicitation is document-heavy and deadline-driven.

Design-Build
Design-build usually gives the owner one team responsible for design and construction. Contractors may lead the team, join as builder, or support a design-builder as a trade partner.
Contractors should review:
- Performance criteria.
- Bridging documents.
- Design responsibility language.
- Required design partners.
- Proposal scoring criteria.
- Qualifications and interview requirements.
- Design contingency, allowances, and exclusions.
See the design-build vs design-bid-build guide for a deeper comparison.
Construction Manager at Risk
CM at risk usually brings construction expertise into the project before design is complete. The construction manager may provide estimating, scheduling, constructability, trade packaging, and later construction services.
Contractors should check:
- Preconstruction service scope.
- Fee, general conditions, and reimbursable cost rules.
- Guaranteed maximum price or similar price structure.
- Trade bidding and buyout requirements.
- Open-book documentation.
- Contingency ownership and use rules.
- Owner approval points.
This method can require more interview, team, and preconstruction documentation than a standard low-bid pursuit.
Construction Manager as Agent
CM agency is a management-services model. The construction manager advises the owner, but trade contracts may sit directly with the owner depending on the program.
Contractors should review:
- Who holds each trade contract.
- Whether the contractor is bidding as a prime, trade contractor, or advisor.
- Who coordinates schedule and site logistics.
- Payment application, change order, and reporting procedures.
- Owner approval workflow.
The risk profile can differ sharply from a single-prime general contract.
Integrated Project Delivery
Integrated delivery uses a collaborative structure where key parties may share governance, incentives, and project outcomes. The exact risk model depends on the contract.
Contractors should review:
- Multi-party agreement terms.
- Required participants.
- Target cost or budget structure.
- Shared risk or incentive language.
- Decision-making rules.
- Cost transparency requirements.
- Dispute resolution process.
Do not assume an integrated delivery pursuit works like a standard bid. Internal finance, operations, and legal review should happen early.
Contractor Pursuit Checklist
Before committing to a project, confirm:
- Delivery method and contract form.
- Selection criteria and scoring weights.
- Whether price, qualifications, interview, or technical approach drives selection.
- Design responsibility and professional liability expectations.
- Preconstruction deliverables.
- Trade partner naming requirements.
- Bonding, insurance, and licensing requirements.
- Addenda and question deadline.
- Internal approval needed for contract or design risk.
Common Mistakes
Using the Same Bid Process for Every Method
A document-driven low-bid workflow will not cover every design-build, CM, or integrated pursuit. Adjust the review process to the contract structure.
Missing Design Responsibility
Design responsibility can appear in performance criteria, proposal language, contract exhibits, or design-assist scopes. Review it before pricing.
Ignoring Selection Criteria
Some pursuits are driven by qualifications, approach, schedule, or interview performance instead of price alone. Align the proposal with the actual scoring model.
Underestimating Preconstruction Scope
Preconstruction services require staffing, estimating time, meetings, reporting, and trade input. Include that effort in the pursuit decision.
Bottom Line
Construction project delivery methods shape how contractors price, staff, and manage pursuit risk. Identify the method early, read the contract structure, and align your bid workflow with the owner's selection process.
The safest approach is to treat delivery method as a first-pass qualification question before estimating begins.
FAQ
Frequently Asked Questions
What are the main construction project delivery methods?
Common delivery methods include design-bid-build, design-build, construction manager at risk, construction manager as agent, and integrated project delivery.
How does delivery method affect contractors?
Delivery method affects when contractors join the project, how complete the documents are, how price is evaluated, who carries design or coordination risk, and what qualifications the owner reviews.
Is design-build the same as design-bid-build?
No. Design-bid-build separates design and construction contracts, while design-build usually gives the owner one contracting team responsible for both design and construction delivery.
Why does CM at risk matter during bidding?
CM at risk often includes preconstruction services, open-book estimating, trade buyout, and a guaranteed maximum price or similar pricing structure depending on the contract.
What should contractors check before pursuing a delivery-method opportunity?
Check the selection criteria, design responsibility, pricing format, contract form, bonding requirements, required qualifications, preconstruction scope, and whether trade partners must be named early.
