Presentation Transcript

  1. I-80 db

  2. I-80 DB Location & Scope • 10 miles on I-80 from Robb Dr. to Vista Blvd. • Reconstruction through congested downtown • Installation of new 10-mile ITS system • Preserved Operational Capacity

  3. I-80 DB • Why Design Build? • Accelerate Schedule • Innovation • Pavement • Traffic Operations • Public Outreach

  4. I-80 DB • Procurement Strategy • Fixed Scope; Lump Sum Price Centers • Evaluation Criteria • 50% Price • 40% Technical • 10% Schedule • Pre-Proposal for Pavement Design • $50K/day early completion incentive

  5. I-80 DB Schedule • Construction began 3 months after NEPA approval • Impacts of Early Completion Incentive • At-Risk Early Start • Completed construction 6 months ahead of original DB schedule

  6. I-80 DB Risk Transfer • Subsurface Conditions • 3rd Party Coordination • Utility Relocation • Public Outreach

  7. I-80 DB • Risk Transfer Leads to Innovation

  8. I-80 DB Innovation • 67 Different ATC’s – 10 Used • Maintenance of Traffic • Auxiliary Lanes • Ramp Meters

  9. I-80 DB Lessons Learned • Aesthetic Concepts/Design • Develop concepts in advance • More prescriptive specs • Soft Subgrade Conditions • Risk is difficult to transfer • Communicate during procurement • Conditional ATC’s • Competing interests • Impacts to acceleration

  10. West Mesquite DB

  11. West Mesquite • Location & Scope • Downtown Mesquite, NV • Replace Diamond Interchange with Roundabouts at Ramp Terminals • Replace Bridges on I-15

  12. West Mesquite • Why Design Build? • Speed of Delivery • Opportunity for Innovation • Reduce Impacts to I-15

  13. West Mesquite • Procurement Strategy • Fixed Scope & Variable Price • Evaluation Criteria • 60% Price • 30% Technical • 10% Schedule • Limit the lane closures on I-15

  14. West Mesquite Schedule • Construction began 1 month after NEPA approval • Completed construction 6 months ahead of engineer’s estimated schedule • 3 months ahead of other Proposers

  15. West Mesquite Risk Transfer • 3rd Party Coordination • Utility Relocation • Public Outreach

  16. West Mesquite Innovation • 30 Different ATC’s – 4 Used • Accelerated Bridge Construction (ABC) • Bridge slide – limited disruption to I-15

  17. West Mesquite Bridge Slide

  18. West Mesquite Lessons Learned • Specifications for Innovation • Hollow Nail Walls • Bridge Deck Quality • Remediation requirements • Innovation & Small DB Projects • Bridge Slide great example

  19. I-15 ITS Design-Build

  20. I-15 ITS Location & Scope • 15 miles of I-15 - South of Las Vegas • Installation of a new ITS system • Integration with RTC’s Freeway and Arterial System of Transportation (FAST)

  21. I-15 ITS • Why Design Build? • Innovation • Technology Expertise • Immediate Need • Minimize traffic impacts

  22. I-15 ITS • Procurement Strategy • Fixed Scope; Lump Sum Price • Evaluation Criteria • 65% Technical • 35% Price • $5k per day early completion incentive

  23. I-15 ITS Schedule • Construction began 1 month after NEPA approval • System was operational 9 months ahead of Bid-Build scenario

  24. I-15 ITS Risk Transfer • 3rd Party Coordination • Utility Relocation • Public Outreach

  25. I-15 ITS Innovation • 10 Different ATC’s - 1 Used • Combination of Wireless & Fiber solutions

  26. I-15 ITS Lessons Learned • Keeping up with Technology • Resources with experience • Evaluating new products • Aligning vendor spec’s/products • Warranties • Consistency among projects

  27. How is Design Build Working for NDOT? • Schedule • Risk Transfer • Innovation
