Public-Private PartnershipPublic-Private Partnership• Nearly $2 billion transportation improvement project• 80-year partnership agreement• Approximately $1.5 billion in private equity and debt• Key risks transferred to private sector, away from taxpayers
– Schedule (fixed date with LD’s of $250K per day)– Cost (Lump Sum)
• State grant and use of innovative federal loan programs• Partnership agreement includes key provisions to protect public interest
– Revenue sharing – No non-compete

Safety – keeping workers and drivers safe
The Challenges• 200,000+ vehicles a day• Tight construction footprint, multiple lane shifts, narrow lanes• Frustrated and distracted drivers/cell phones • Large amount of night work• Aggressive schedule – entire 14 miles under construction

Safety – keeping workers and drivers safe
Results: • Fewer serious work zone accidents• 2.8 million safe hours on job with only one lost time• .84 OSHA Rate• Increased program ownership at all levels• Still a work in progress

Construction• Construction Approach
– Design/Build • Design packaging feeds into construction planning• Just in time design• Construction involvement in design
– Unique Contractual Relationship – Project divided into 4 construction area – Construction Area Manager and independent construction team– VDOT/GEC leads paired with area managers– Key decision making level – Most interchanges 3 stage construction approach
• 12–18 month schedule savings realized at 2 interchanges by switching to a 2 stage approach

Construction• Work Phasing
–Build outer 2 lanes: 2008 – 2011–Rebuild/lengthen all bridges & overpasses
along alignment: 2008 – 2011–Shift traffic into two new outer lanes: 2010 - 2011 –Build inner two (HOT) lanes: 2011 – 2012

Construction• Demolition Approach
– Bridge demo at night to allow needed lane closures – Noise an issue to nearby residents and hotels.
• Utilized techniques to speed work while decreasing noise•Media & public outreach
– Maximize lane closures and duration of closures to increase hours available for demolition (in some cases coordinate with the state to provide full road closures, with detours in place, to accelerate demolition

Construction• Field Construction
– Detailed planning and coordination, particularly when in close proximity to third party construction (Dulles Metro)
– Balance of self perform and subcontract resources to maximize work fronts
– Close internal coordination between functions (roadway, structures, MOT, utilities) to maximize efficiency of the work and interface between groups
