2
Learning Outcomes By the end of this Module, you will be able to: identify customer needs from a Utah perspective recall the benefits of using PBES recall the concept of user costs identify associated risks from Utahs perspective identify lessons learned
3
Utah Small State – 2.5 M people – $350 M Federal Program – DOT 1650 employees Big Transportation Program – 250+ projects – $2.0 B+ under construction
4
UDOTs Need for Speed Customer driven culture Implement new technologies: – Accelerated Bridge Construction – Accelerate Pavement Construction – Diverging Diamond Interchanges Increased partnerships Match Legislative tempo
5
Department Themes Accelerate Delivery Decrease and Minimize Detours or Delays Encourage Innovation that speeds project or provides value Get a Good Price Balance of good price vs. other themes
6
New Business Model Societal Costs Minimized Lowest Construction Cost Lowest Project Cost Public Praise Political Capital
7
What is PBES from a Utah perspective? Innovative methods to decrease bridge construction time Build elements offsite/outside traffic area Transport to site and install rapidly
