Design-Bid-Build completes the project in phases. The owner first hires the design team (architects and engineers), and the team completes the design through 100% Construction Documents (CDs). The complete construction set is then sent out to bid to multiple contractors. A contractor is selected and hired by the owner. During the construction phase, the architect and engineer provide responses to Requests for Information (RFI’s) and review submittals, but design iteration/advancement beyond the Construction Document set is typically limited.
