Design-Build

What is Design-Build?

Design-build is a procurement method wherein ODOT contracts with a single entity with needed design and construction capability to perform the project, including all design, construction, and contract administration. The agency retains oversight of the design-build contract. This type of contracting can be advantageous in a number of instances, with one of its main strengths being its ability to effectively implement schedule critical projects.
The agency invites contracting entities to submit proposals for the design and construction of the project. The agency will perform approximately 15 to 30 percent of the initial design, and may provide some conceptual plans in order to accurately relay the intent of the contract. The design-build proposers submit proposals for design, construction, time, and cost to perform all aspects of the project. The proposals are evaluated based on quality and price, and the best value proposer is awarded the contract. The agency then provides oversight during design and construction.
The design-build procurement method is very complex and requires additional staff time to draft and manage additional procurement documents and perform proposal evaluations and scoring.
ODOT uses unique and dedicated design-build general provisions (DB General Provisions) boilerplates that are specifically written to provide the terms and conditions under which the bidding requirements, evaluation, and award are conducted, and the design and construction work for all design-build projects are performed. The DB General Provisions replace the ODOT Standard Specifications part 00100s.
ODOT utilizes the following DB General Provisions, Standard Specifications and Special Provisions for its design-build program:
  • DB General Provisions Boilerplate: Consists of sections 110 through 199
  • DB Standard Specifications: Consists of parts 00200 through 03000 of the Oregon Standard Specifications for Construction
  • DB Standard Special Provisions: Consists of ODOT-supplied additions and revisions to the DB Standard Specifications

What is Design-Bid Low Bid?

 
Design-Build Low Bid provides a more streamlined means for delivery than is presently available in Design-Build Basic. The primary differences between DB Basic and DB Low Bid are the allocation of responsibility and risk, and the award criteria. DB Low Bid places more responsibility on the Agency in regard to quality, environmental permitting and compliance, and third party conflict resolutions. 
 
DB Low Bid provides flexibility to do more projects with less cost and/or the potential for “fast-tracking” the delivery. DB Low Bid should be easier and less expensive for the Designer, the Contractor/Builder and ODOT.
