Choosing between design-build and design-bid-build project delivery can impact your entire construction experience—from budget certainty and communication flow to speed of completion. Many owners prefer design-build because it simplifies contracts, reduces surprises, and can cut months off your schedule.
At Roche Constructors, we’ve executed hundreds of projects under both models. Here’s how each method works, how they compare, and which one may be the better fit for your next build.
What Is Design-Build?
Design-build is a project delivery method in which one entity handles both design and construction. Also known as an integrated project delivery or turnkey construction model, this approach enhances collaboration by integrating architects, engineers, and builders from the outset.
Learn more about our design-build services and how this model can streamline your project.
What Is the Traditional Design-Bid-Build Model?
The traditional model separates design and construction. You hire a designer, finalize the plans, and then bid out the build. While this approach offers distinct design authority, it often involves more change orders and coordination from the owner’s side.
Comparison Table
| Criteria | Design-Build | Design-Bid-Build |
|---|---|---|
| Contract Structure | Single contract | Separate design & construction |
| Timeline | Faster (phased/overlapping) | Slower (linear phases) |
| Cost Efficiency | Fewer delays and change orders | Potential for friction and rework |
| Owner Involvement | Lower | Higher |
| Risk Distribution | Shared | More on owner |
| Changes & Conflicts | Fewer | More likely |
When to Choose Design-Build
It’s a misconception that design-build is more expensive. In fact, many clients save money by avoiding delays, minimizing change orders, and aligning the team early. While initial design costs may be bundled, the overall project typically runs more efficiently.
Choose design-build when:
- You’re facing a tight timeline
- You want cost clarity before the design is finished
- You need to reduce risk and coordination effort
- You’re building a complex facility with evolving requirements
When Design-Bid-Build Makes Sense
This model works well when you:
- Already have complete architectural plans
- Want to bid construction after full design
- Have capacity to manage separate contracts
- Need full design control (e.g., public sector projects)
