- (a) A D-B project will normally advance through the early stages of project development in the same manner as a DB-B project, however, each D-B project is unique and the Arkansas Department of Transportation must carefully assess the project development strategy for each project.
- (b) The project development process for D-B projects is generally the same as that used for traditional DB-B projects until approximately the twenty percent (20%) to thirty percent (30%) level of preliminary engineering and associated studies and the environmental process.
- (c) At that point, the D-B project development process is differentiated by the fact that preliminary engineering and other preliminary data gathering and studies are assembled and packaged as part of the reference information documents (RID) provided to the short-listed proposers for use in the preparation of their proposal and subsequently for the selected design-builder for use and reference during the final design and construction as discussed in Subpart 4, Design-Build Project Procurement Process.
- (d) Typical activities in the project development process for D-B projects are discussed in further detail in the following sections.
