In the Design-Build delivery method, a contract is between the Owner and a single entity: the Design-Build Team. This results in a single source of accountability for the duration of the entire project. Design-Build project delivery is ideal for a project under tight schedule circumstances because construction scheduling for the project can begin before the design is finalized. Additionally, bid time is reduced and potential construction issues that could occur in the field are typically uncovered and mitigated earlier in the process.
In a Design-Build agreement, the Owner receives a comprehensive design and construction project cost early in the process (as opposed to the traditional General Contracting/design-bid-build method where the Owner must wait for bid results).
