Project Delivery (Design-Build) Guidance

Departments of Transportation (DOTs) across the country have traditionally used a Design-Bid-Build procurement method in building highways and other transportation infrastructure improvements. The Design-Bid-Build method is when the DOT—or a consultant hired by the DOT—designs the project, after which bids from contractors are solicited, and, finally, the project is awarded to a contractor to build that project. This process encourages competitiveness among bidders; however, it often requires a high expenditure of resources and time in the DOT’s project-design phase. Further, any innovation in construction or materials for a project must be identified, defined, and included in the contractor’s bid package, which restricts flexibility to develop additional innovations after award. The primary objectives of this research study are to seek data to inform ADOT on DB policies and procedures for future project-delivery and legislative efforts. This research will include information from other state DOTs on their PDB and/or DB efforts, state legislative authority, standing policies, contractual documents, etc. It will also include how PBD and/or DB is implemented in other states as well as any notable practices they use when utilizing these contracting methods.
