The transportation construction world continues to learn lessons about risk and relationships in design-build. With an unprecedented amount of federal aid anticipated for highway, bridge and transit projects, it is also starting to move further toward progressive design-build (PDB).
“Progressive design-build is new in transportation,” said Dave Nardon, director of alternative delivery for Superior Construction. “Just a couple of years ago, if you asked twenty people what progressive design-build is, you’d get thirty answers. It’s not [construction manager-general contractor] or design-build."
