Progressive Design Build (PDB)

In a PDB project, the owner selects a team based on qualifications or best value criteria—not just lowest cost—followed by a collaborative process to a final design and price. Key features include early retention of the contractor, selection based on qualifications, and delivery of the project in two distinct phases: Phase One includes a budget-level design, while Phase Two includes the completion of the project's design and construction.
