Get Your Motor Running – How a Validation Period Jump Starts the PDB Process

The first step in a Progressive Design-Build (PDB) process is for the parties to validate the project through what DBIA has termed the “Validation Period”. The parties must become aligned regarding the scope, schedule, and budget before collaboratively developing the remainder of the project. It is also important to perform a thorough review of the major risks associated with the project at the beginning to develop a plan for managing project risks throughout the project. Four PDB experts – An Owner, Design-Builder, designer and attorney – will guide participants through the Validation Period and discuss how to structure an effective Validation Period, strategies to achieve consensus and provide lessons learned. The four panelists are all members of the DBIA PDB Resources Committee.

Learning Objectives:

  • Understand the critical importance of a complete and thorough “Validation Period” as the foundation of a successful Progressive Design Build (PDB) project.
  • The successful development of PDB project Target Budgets, Scopes, and Schedules resulting from a well-executed “Validation Period”.
  • A broader understanding of how to develop and utilize “Benchmarking” in the Validation and Target development portion of the Project Definition Phase.
