2 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 I-80 DB Location & Scope

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

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

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 3 rd Party Coordination Utility Relocation Public Outreach

7 I-80 DB Risk Transfer Leads to Innovation

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

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

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

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

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

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

15 West Mesquite Risk Transfer 3 rd 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

20 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) I-15 ITS Location & Scope

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

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

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 3 rd Party Coordination Utility Relocation Public Outreach

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

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