As an Owner, WSDOT brings significant Design-Build experience to the project allowing them to execute the project effectively. WSDOT uses this experience to evaluate Alternative Technical Concepts (ATCs) during the proposal phase. During the execution phase of the project, WSDOT makes sure they receive the ATCs they expect while allowing the Design-Builder the latitude to be innovative and construct a quality project.

1) Explain the WSDOT process for selecting an ATC during the procurement phase of the project – Equal or Better.

2) Demonstrate how WSDOT distributes the proposed ATC information from unsuccessful DB teams to the selected DB team.

3) Describe how WSDOT works with the Design-Builder during the design phase to make sure WSDOT receives the ATC that the DB initially proposed.

4) During the construction phase, describe how oversight and quality verification of ATC items differ from other items
