DEFINITION OF DESIGN BUILD:
Design Build, typically faster than the traditional design-bid-build process, combines the design and construction of a project into one contract. The designing firm and construction contractor become a team, working concurrently on the design and construction phases of a project, expediting delivery.
The time savings in design build projects is realized by eliminating the lead time necessary to contract a designer, and then accept bids from contractors to build the design. Projects move from design to construction much faster through the use of the single design build contract.
Additionally, because the designer and contractor work in tandem, the contractor's changes can be incorporated into the design phase, eliminating the need for costly and time consuming changes during construction. This benefit also allows the department to estimate project cost early in the project development process, allowing for more effective budget planning.
LEAST COST AND VALUE BASED DESIGN BUILD PROCESSES
The Department uses two types of Design Build contracting; Least Cost (also known as One-Step) and Value Based (also known as Two-Step). In Least Cost Design Build contracting, the Design Build contract is awarded to the lowest responsive and competent bidder. In Value Based Design Build contracting, the Design Build contract is awarded to the bidder with the best value score. Best value scores are determined based on a combination of bid price and a technical qualifications assessment.
DESIGN BUILD PROJECT LIST:
Please note that information regarding the projects listed in the Design Build Project Summary spreadsheet is based on planning information in Ellis. Contact the appropriate District to determine if any additional information is available for upcoming projects shown on the list (District Phone Numbers).
PROJECT SUBMITTALS:
Information regarding submittal information for design-build projects can also be found at the following link (Internal ODOT only): Contracts - Submittal Information (Internal Only). The submittal schedules assume a 23 week processing time (plan package delivery through award). Districts may request accelerated schedules for non-complex projects by contacting the Office of Contracts.
PREBID QUESTIONS:
The correct address for prebid questions referenced in Section 3 of the Least Cost Design Build Scope Form is: http://www.dot.state.oh.us/Divisions/ContractAdmin/Contracts/Pages/PBQs.aspx. The address is correct in the downloadable scope form, but may not be correct if an older version of the form was used to create the Design Build scope.
