Capital Beltway HOT Lanes Our Challenges
Successes
Herb Morgan Vice President Fluor Infrastructure
2
Welcome to Northern Virginia
  • 2nd most congested region in US
  • Population growing at twice national rate
  • Polls show transportation 1 issue
  • Beltway congested 6-8 hours per day
  • Costs local economy 5.5 billion a year

3
Public-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 LDs 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

4
Stimulating the Local Economy
  • Construction of 2 Billion Capital Beltway
    HOT Lanes is expected to
  • Support 11,200 jobs
  • Generate 2.7 billion in economic benefit for
    region 2008-2013
  • Contribute 10 of job growth and 20 of total
    economic growth in Fairfax County
  • Commitments with 103 Disadvantage Business
    Enterprise (DBE) firms and 118 Small Woman and
    Minority (SWaM) firms totaling 368M

Overview of Improvements
  • Two new lanes (High Occupancy Toll) in each
    direction from Springfield Interchange to north
    of Dulles Toll Road (14 miles)
  • Upgrades to 11 key interchanges
  • Improved connections for all new interchanges,
    particularly at I-66
  • Building 58 new bridges and overpasses
  • New HOT Lanes dynamic tolling system
  • More than 80,000 linear feet of new sound walls,
    protecting neighboring communities
  • New bike paths and sidewalks on
  • every Beltway crossing

I-66 at I-495
Schedule
  • 5 years Dec. 2007 Dec. 2012
  • 30 design to final detailed design
  • ROW acquisition (144 parcels)
  • Utility relocations
  • (12 owners 102,000 feet of utilities)
  • Construction
  • Start up / check out tolling system
  • Toll Revenue - December 20, 2012

Key Construction Metrics
  • One of largest highway improvement projects in
    U.S (1.4B Design Build Contract).
  • Over 900 employees and subcontractors on the job
  • Current 35 - 40 million per month burn rate
  • 73,513 cubic yards of concrete
  • 1.3 million tons of asphalt
  • 21.4 thousand tons of steel
  • 224 pieces of heavy equipment
  • 890,000 sq. ft. of retaining walls
  • 80,000 linear ft. of sound walls

Significant Project Challenges and Successes
  • 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

10
Significant Project Challenges and Successes
  • Safety keeping workers and drivers safe
  • Action Steps
  • Emphasize total team commitment to Safety
  • Set and track safety expectations
  • Utilize engineered safety controls
  • whenever possible
  • Aggressive VDOT media outreach
  • Orange Cones No Phones
  • Construction activities

11
Significant Project Challenges and Successes
  • 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

12
Significant Project Challenges and Successes
  • 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
  • 1218 month schedule savings realized at 2
    interchanges by switching to a 2 stage approach

13
Significant Project Challenges and Successes
  • 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

Significant Project Challenges and Successes
  • 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

Significant Project Challenges and Successes
  • Construction
  • Demolition Approach
  • Utilize specialist demo subcontractor with
    specialized
  • demolition equipment (Hydraulic shear, large
    hydraulic claw)
  • Careful planning of the work
  • to make most efficient use of
  • the lane closure window and
  • maximize productivity

Significant Project Challenges and Successes
  • Construction
  • Field Construction
  • Switch from drilled shafts to
  • driven piles
  • Utility relocation work
  • sequencing
  • Integrated Right of Way
  • acquisition process
  • Multiple work fronts within each
  • interchange
  • Double shift and weekend work
  • of critical activities

17
Significant Project Challenges and Successes
  • 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

Project Successes
  • Conclusion
  • Moving from 30 design review to ROW
    acquisition, utility relocation, construction
    toll service within 5 years -
  • remarkable accomplishment
  • VDOT/GEC/Transurban/Fluor-Lane have worked hard
    to succeed in this PPP
  • Truly unique project
