Design-Build Method

The design-build (DB) method uses a contract with a single entity, who handles both design and construction. This method encourages innovation and often results in accelerated project completion.  
ODOT uses a two-stage procurement process for DB projects. The request for qualifications (RFQ) comes before a request for proposal (RFP). ODOT selects applicants from the RFQ to take part in the RFP. These candidates develop and submit proposals to
design and construct the project. 

ODOT awards the contract based on price and other best value criteria such as: 
  • Proposed technical approach to the work. 
  • Qualifications. 
  • Past performance.

Why use the Design-Build method? 

This method works best for complex projects with minimal third-party involvement. Having a combined design and construction team makes problem solving easier. This creates opportunity for new ideas and shorter timelines.

What does a Design-Build contract involve? 

Design-Build projects include one contract with the design-builder.  

The design-builder may subcontract a design consultant.

What are the contracting phases of the Design-Build method? 

Design-Build projects begin with a conceptual design phase before a two-step selection phase. Selection consists of an RFQ and an RFP. After ODOT awards the contract, the design-builder will start working on the final design. Design work can overlap with early construction. The design-builder then completes the construction. This approach may decrease the project timeline.
