Presented by James McMinimee, P.E., P.S.E. UDOT Chief Engineer, Director of Project Development Accelerated Bridge Construction (ABC): the Keys to Success from an Owners Perspective
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 Utah’s perspective • identify lessons learned
Utah • Small State • 2.5 M people • $350 M Federal Program • DOT 1650 employees • Big Transportation Program • 250+ projects • $2.0 B+ under construction
UDOTs Need for Speed • Customer driven culture • Implement new technologies: • Accelerated Bridge Construction • Accelerate Pavement Construction • Diverging Diamond Interchanges • Increased partnerships • Match Legislative tempo
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
Societal Costs Minimized • Lowest Construction Cost Lowest Project Cost • Public Praise • Political Capital New Business Model
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
UDOT ABC History • 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 Slabs 10 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/7Bridges • Heavy Lift Cranes: 3 Projects/4 Bridges
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
7 Superstructures Constructed in a Single Location Operation Staging AreasBridge Farm @ 1300 East
Risk Identification – Owner, Contractor and Engineer • Identified 5 Categories w/ 135 Items: • Carrier Beam • Perform 2 independent QCs • Utilities • Shutting down large H2O line • Travel Path • Verify/confirm travel over new bridges • Geotech • Re-evaluate projected utility/wall stresses • Launch • Re-evaluate all assumptions
Lessons Learned and Best Practices- State perspective • 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 • Engage the industry A
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.
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 Utah’s perspective • identify lessons learned and best practices
Polling Questions • What are 3 best practices for implementing PBES
