1 ACCELERATED BRIDGE CONSTRUCTION (ABC): THE KEYS TO SUCCESS FROM AN OWNERS PERSPECTIVE Presented by James McMinimee, P.E., P.S.E. UDOT Chief Engineer, Director of Project Development

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

8 UDOT has over 170 bridges total, completed or under construction that utilized ABC* Self Propelled Modular Transports: 6 Projects/19 Bridges Half Thickness Precast Deck Panels: 5 Projects/74 Bridges Full Depth Precast Deck Panels: 15 Projects/21 Bridges Precast Voided slabs: 1 Project/2 Bridges Approach Slab Panels: 10 Projects/15 Bridges Precast Sleeper Slabs10 Projects/15 Bridges Precast Abutments:3 Projects/5 Bridges Precast Bent Caps:2 Projects/2 Bridges Precast using Sliding:5 Project/10 Bridges Precast Box Culvert: 3 Projects/7 Bridges Heavy Lift Cranes: 3 Projects/4 Bridges UDOT ABC History

9 Innovative Technology First implementation costs more Potential for new methods to cost less Promise of time savings Positive cost-benefit ratios Promise of programmatic cost savings

10 Costs of PBES

11 Operation Staging Areas Bridge 1300 East 7 Superstructures Constructed in a Single Location

12 Risk Identification – Owner, Contractor and Engineer Identified 5 Categories w/ 135 Items: – Carrier Beam Perform 2 independent QCs – Utilities Shutting down large H 2 O line – Travel Path Verify/confirm travel over new bridges – Geotech Re-evaluate projected utility/wall stresses – Launch Re-evaluate all assumptions

13 2009 Slide-ins= Innovation

14 Public Perceptions

15 Get Department Leadership Committed and Involved Provide Adequate Contractor discussion Obtain Funding for Demonstration Projects Plan a program of projects – not just 1 Use Innovative Contracting Scanning Tours Communicate with Industry, Utilities, Local Governments and Your Agency Lessons Learned and Best Practices- State perspective

16 Lessons Learned and Best Practices Engage the industry A

17 Culture or innovation You will know success when Regions and contractors are using and improving Innovation without central prompting ABC - SPMT, Precast, Improvements in Slide-in Projects.

18 Module Conclusion You should now be able to: identify customer needs from a Utah perspective recall the concept of user costs identify associated risks from Utahs perspective identify lessons learned and best practices

19 Polling Questions What are 3 best practices for implementing PBES

20 Module Conclusion QUESTIONS & DISCUSSION
