7 Steps to Choose a Construction Delivery Method
Quick Summary
A construction delivery method is the structure that defines who designs a project, who builds it, and how they are paid and held responsible. The main options are design-bid-build, design-build, and construction manager at risk, and each splits design, construction, and risk differently. Choosing one early shapes your budget, schedule, and coordination workload.
- Design-bid-build hires the designer first, then selects a general contractor through competitive bidding.
- Design-build puts one team in charge of both design and construction under a single contract.
- Construction manager at risk brings the builder in early, then guarantees a price before construction starts.
- Score each method against weighted criteria such as cost certainty, schedule speed, and change-order exposure.
- Run the leading method against owner readiness, lifecycle cost, and procurement constraints before committing.

What a Construction Delivery Method Is and Why It Matters
Last Updated: October 30, 2026
A construction delivery method is the structure that defines who designs a project, who builds it, and how those parties are paid and held responsible.
Many owners treat delivery method as a paperwork question. It is more than that. The method decides when the designer and builder talk to each other, who carries the risk when drawings are incomplete, and how changes get priced.
The core choice usually comes down to a few questions:
- Who designs the project? The owner's architect, or the builder's team?
- When is the builder hired? Before the design is finished, or after?
- How is the price set? A fixed number, a cost plus fee, or a guaranteed maximum?
Answer those four questions and you have narrowed the field to one or two realistic methods. The rest of this guide walks through each option, the criteria to score them, and a worked example so you can apply the same logic to your own job.
Construction Project Delivery Method Comparison: The Main Options
The main delivery methods are design-bid-build, design-build, and construction manager at risk.
Design-bid-build is the traditional route. The owner hires a designer first, finishes the drawings, and then selects a general contractor through competitive bidding.
Design-build puts one team in charge of both design and construction under a single contract.
Construction manager at risk brings a builder on early as a consultant, then has them guarantee a price for the work before construction starts.
Design-Bid-Build vs Design-Build: How the Contracts Differ
The biggest practical difference between these two methods is who you contract with for design. In design-bid-build, you sign separate contracts with the architect and the builder. In design-bid-build, you sign separate contracts with the architect and the builder, and the two parties have no formal contract with each other.
In design-build, you sign one contract with one team. That team answers for the drawings and the construction. If something in the design causes a delay in the field, you talk to one party.
Pros of design-bid-build
- Competitive bidding can lower the price
- You control the design fully before anyone bids
- Familiar process with many experienced bidders
Cons of design-bid-build
- Design problems often show up during construction
- Change orders are common when drawings are incomplete
- You coordinate the architect and the subs yourself
Pros of design-build
- One point of contact from concept to finish
- Faster overall schedule because design and construction overlap
- Fewer disputes between designer and builder
Cons of design-build
- Less owner control over individual design decisions
- Price is often set earlier, before full drawings exist
- Selection can rely more on qualifications than the lowest bid
Construction Delivery Method Selection Criteria You Should Score
Most guides tell you to weigh budget, schedule, complexity, and risk. That advice is correct but not usable, because it never tells you how to combine those factors into a defensible choice. The approach below turns the general advice into a repeatable scored matrix you can run in about an hour and defend to a lender, a board, or a partner.
Step 1: Weight the criteria before you score any method
Decide how much each factor matters to this specific project, on a 1-to-5 scale, before you look at any delivery method. Weighting first prevents you from rationalizing toward a method you already prefer.
| Criterion | What it measures | Weight (1-5) |
|---|---|---|
| Cost certainty | How early and how firmly the final price is set | |
| Schedule speed | Ability to overlap design and construction | |
| Design control | Owner influence over finishes, systems, and details | |
| Change-order exposure | Likelihood that incomplete drawings create extra charges | |
| Owner coordination load | Staff time and experience needed to manage the team | |
| Risk transfer | How much design and cost risk shifts away from the owner | |
| Lifecycle cost | Total cost of ownership, not just initial price |
A tight-funding project might weight cost certainty at 5 and design control at 2. A signature building might invert those. There is no universal weighting, the point is to write yours down before scoring.
Step 2: Score each method against your weights
Rate each candidate method from 1 to 5 on every criterion, then multiply by your weight and total the column. A simple spreadsheet is enough.
A common pattern is that design-bid-build scores high on design control and low on schedule speed and change-order exposure, while design-build scores the reverse. Construction manager at risk often lands in the middle, which is why it is popular for projects with complex scope but a firm budget ceiling.
Step 3: Stress-test the leading method against five realities
The scored matrix ranks methods on your stated priorities. Before you commit, check the leader against the factors owners most often skip:
- Owner readiness and internal capacity. Do you have staff who can review drawings, run progress meetings, and approve change orders within a day or two? If not, a single-contract method like design-build shifts coordination to the team, even if the price is slightly higher. Owners with no construction staff routinely underestimate this.
- Lifecycle cost and change-order exposure. Initial price is not total cost. Design-bid-build often produces the lowest bid but the highest change-order volume when drawings are incomplete, because the contractor prices only what is drawn. Design-build and CM at risk tend to price more of the unknowns up front through contingencies and allowances. Compare total exposure, bid plus expected changes plus contingency, not just the bid.
- Contract type versus delivery method. These are related but distinct choices, and confusing them is the most common source of bad comparisons. Delivery method defines who contracts with whom and when the builder is hired. Contract type defines how the builder is paid, lump sum, cost plus fee, or guaranteed maximum price. You can pair design-bid-build with a lump-sum contract, or design-build with a guaranteed maximum price. Score the delivery structure first, then choose the payment terms that fit your risk tolerance.
Step 4: Document the decision
Write a one-page memo that records your weights, your scores, the leading method, and the reasons you accepted or overrode the result. This document is useful when you seek financing, brief a board, or explain to a contractor why you chose a particular structure. It also forces you to name the trade-off you are accepting, because every method trades something away.
A Worked Example: Choosing a Method for an Occupied Office Renovation
A single example is not enough to show how the framework behaves, because the right answer changes with the project type. Below are four common scenarios, each run through the same weighted matrix, so you can see how the recommendation shifts and why.
Scenario 1: Occupied office renovation, tight schedule
A small business owner is renovating a 4,000-square-foot office while staff keep working. The space must be finished in about four months, and long shutdowns are unacceptable.
Weights: schedule speed 5, owner coordination load 5, cost certainty 3, design control 2.
Design-build scores highest because design and construction can overlap and the owner manages one contract. A guaranteed maximum price gives enough cost certainty without demanding a fully finished design before pricing.
Scenario 2: Renovation with uncertain existing conditions
An owner is renovating an older building where the drawings do not match what is behind the walls. Scope is genuinely uncertain until demolition exposes the structure.
Weights: change-order exposure 5, cost certainty 4, schedule speed 3, design control 3.
Design-bid-build is a poor fit here, because bidders price only what is drawn and every surprise becomes a change order.
Scenario 3: Fast-track commercial project with a fixed opening date
A tenant improvement must open by a lease date that cannot move. Design must start before the full scope is known.
Weights: schedule speed 5, risk transfer 4, cost certainty 4, design control 2.
Design-build is the clear leader because it is built for overlapping design and construction. The owner should insist on a guaranteed maximum price with a clear allowance schedule so cost overruns above the cap sit with the team, not the owner.
Scenario 4: Public or publicly funded project
A project uses public funds and is subject to procurement rules that may require competitive bidding or specific selection procedures.
Weights: compliance 5, cost certainty 4, design control 4, schedule speed 2.
Design-bid-build is often the default because it satisfies competitive-bidding requirements most cleanly. Design-build may be available if the jurisdiction permits it and the owner follows the required selection process.
What the four scenarios show
The method changes with the project, not with the owner's preference. Schedule pressure pushes toward design-build. Uncertain scope pushes toward construction manager at risk. Public procurement often pushes toward design-bid-build. The scored matrix makes those trade-offs explicit instead of leaving them to habit.

Frequently Asked Questions
What are the different types of project delivery methods?
The most common project delivery methods are design-bid-build, design-build, construction manager at risk (CM at risk), and integrated project delivery (IPD). Design-bid-build separates design from construction and selects a contractor on the lowest responsible bid. Design-build puts one team in charge of both design and construction under a single contract. CM at risk brings a construction manager in early as a pre-construction advisor who guarantees the price before work starts. Integrated project delivery ties owner, designer and contractor together under shared risk and reward. Each structure allocates cost, schedule and responsibility differently, so the right choice depends on the project's budget certainty needs, complexity and how involved the owner wants to be.
How do you choose a construction project delivery method?
Start by ranking your priorities: budget certainty, schedule, design control, and how much risk you are willing to carry. If cost certainty and a fast start matter most, design-build or CM at risk usually fit better. If you want the lowest price on a fully designed project and have time for bidding, design-bid-build gives you a competitive price on defined drawings. Score each option against those priorities, then check the owner's internal capacity to coordinate. A method that looks cheap on paper can cost more if the owner must manage the coordination between architect and subcontractors.
Which construction delivery method offers the most owner control?
Design-bid-build generally gives the owner the most control over the design, because the owner's architect completes full drawings before a contractor is hired. The tradeoff is that the owner carries more of the risk for design errors and change orders. Design-build gives the owner less direct control over design decisions during the process, but it provides a single point of responsibility. Owners who want strong design authority with fewer coordination headaches often choose design-bid-build with an experienced general contractor involved early for constructability input.
Which construction delivery method is best for a tight schedule?
Design-build and CM at risk are usually the fastest options because construction can begin before design is fully complete, a practice called fast-track construction. Design-build overlaps design and construction under one contract, which removes the sequential bidding step. Design-bid-build is typically the slowest because it finishes all drawings and then runs a competitive bid before construction starts. Owners with tight timelines should confirm that the chosen contractor can staff and sequence work while design is still being finalized.
