Design-Build vs. Design-Bid-Build: Market Share and What It Means for You

TL;DR: Design-build has become the dominant project delivery method in the U.S. FMI’s 2024 Design-Build Utilization Study projects it will represent more than 47% of U.S. construction spending by 2028, and DBIA’s 2025 Design-Build Data Sourcebook puts it near 50%. For anyone selling into construction, that shift changes who you need to reach and how early.

In design-bid-build, the owner hires a designer, completes the design, then puts the project out for pricing to contractors as a separate step. In design-build, a single team delivers both design and construction under one contract. The difference matters: design-build selects the builder early, during design, rather than after the drawings are finished.

Design-build’s share of U.S. construction spending has climbed for years. FMI’s 2024 study forecasts it will exceed 47% of spending by 2028, representing more than $1.1 trillion over five years, while DBIA’s 2025 Data Sourcebook projects nearly 50%. The largest design-build investment is expected in the manufacturing, highway and street, and education sectors.

Owners choose design-build for speed and accountability. With one team responsible for both design and construction, projects move faster and there is a single point of responsibility. FMI reports design-build projects are delivered markedly faster than traditional design-bid-build, which is why more owners default to it on complex, time-sensitive work.

The rise of design-build raises the value of early access. When the builder is selected during design, the winners are the teams already in the conversation, not the ones waiting for a public opportunity. That is exactly where Construct-A-Lead helps: we surface commercial construction projects in the pre-planning stage, with verified decision-maker contacts, updated in real time across the U.S. and Canada, so you can reach the right people before the team is set.
