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
Accelerate Schedule Innovation – Pavement – Traffic Operations – Public Outreach I-80 DB Why Design Build?
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
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
I-80 DB Risk Transfer Subsurface Conditions 3 rd Party Coordination Utility Relocation Public Outreach
I-80 DB Risk Transfer Leads to Innovation
67 Different ATC’s – 10 Used Maintenance of Traffic Auxiliary Lanes Ramp Meters I-80 DB Innovation
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
West Mesquite Location & Scope Downtown Mesquite, NV Replace Diamond Interchange with Roundabouts at Ramp Terminals Replace Bridges on I-15
Speed of Delivery Opportunity for Innovation Reduce Impacts to I-15 West Mesquite Why Design Build?
Fixed Scope & Variable Price Evaluation Criteria – 60% Price – 30% Technical – 10% Schedule Limit the lane closures on I-15 West Mesquite Procurement Strategy
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
West Mesquite Risk Transfer 3 rd Party Coordination Utility Relocation Public Outreach
West Mesquite Innovation 30 Different ATC’s – 4 Used Accelerated Bridge Construction (ABC) Bridge slide – limited disruption to I-15
West Mesquite Bridge Slide
West Mesquite Lessons Learned Specifications for Innovation Hollow Nail Walls Bridge Deck Quality Remediation requirements Innovation & Small DB Projects Bridge Slide great example
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
Innovation – Technology Expertise Immediate Need – Minimize traffic impacts I-15 ITS Why Design Build?
Fixed Scope; Lump Sum Price Evaluation Criteria – 65% Technical – 35% Price $5k per day early completion incentive I-15 ITS Procurement Strategy
I-15 ITS Schedule Construction began 1 month after NEPA approval System was operational 9 months ahead of Bid-Build scenario
I-15 ITS Risk Transfer 3 rd Party Coordination Utility Relocation Public Outreach
10 Different ATC’s - 1 Used Combination of Wireless & Fiber solutions I-15 ITS Innovation
I-15 ITS Lessons Learned Keeping up with Technology Resources with experience Evaluating new products Aligning vendor spec’s/products Warranties Consistency among projects
Schedule Risk Transfer Innovation How is Design Build Working for NDOT?
