Work Zone Safety Using Accelerated Bridge Construction (ABC)

Rukhsana Lindsey, UDOT

Presented by Jim McMinimee

Principal Engineer, Applied Research Associates


Utah

  • Small State

    • 2.5 M people

    • $350 M Federal Program

    • DOT 1650 employees

    • Currently 6% unemployment statewide

  • Big Transportation Program

    • 250+ projects

    • $3+ B under construction


Our need for speed
Our Need for Speed

  • Customer driven culture

  • Willing to take risks

  • Implement new technologies:

    • Accelerated Bridge Construction

    • Accelerate Pavement Construction

    • Diverging Diamond Interchanges

  • Increased partnerships


Department themes
Department Themes

  • Accelerate Delivery

  • Decrease and Minimize Detours or Delays

  • Encourage Innovation that speeds project or provides value

  • Get a Good Price

    Balance of good price vs other themes


New business model

  • Societal Costs Minimized

  • Societal cost model includes safety costs

  • Lowest Construction CostLowest Project Cost

  • Public Praise

  • Political Capital

New Business Model


I 15 design build a case study in project acceleration
I-15 Design Build a Case Study in Project Acceleration

  • I-15 Design Build – SEP 14

    • $1.6 B Contract

    • 17 Miles, 130 Bridges, 7 Urban/3 Interstate Interchanges

    • 10 Year Maintenance Period

  • Drivers for Project

    • Public Support – 4 Years Instead of 9 Years

    • 2002 Winter Olympics

  • I – 15 Incentives

    • Quality, Project Management, MOT, Early Completion

    • Potential $50M

  • Post Mortem User Cost Study UofU Dr Martin

    • USER COSTS SAVED > $500M

    • Saved estimated 4400+ accidents over Traditional

    • 14 Lives Saved


What is abc
What is ABC?

  • Innovative methods to decrease bridge construction time

  • Build elements offsite/outside traffic area

  • Transport to site and install rapidly


Benefits of abc
Benefits of ABC

  • Minimized traffic disruption – from months to days

  • Improved work zone safety – improved worker safety

  • Improved product quality – controlled environment, cure times, easier access, etc.


Innovative technology
Innovative Technology

  • First implementation costs more

  • Potential for new methods to cost less

  • Promise of time savings

  • Positive cost-benefit ratios

  • Promise of cost savings

Udot research study
UDOT Research Study

  • Reviewing status of ABC Program

  • 161 ABC projects

  • Started with SPMT projects


Preliminary results
Preliminary Results

  • 18 Accelerated Bridge Projects- SPMTs

    • Traffic impacts Closures and Detours of 2-3 days

    • Channelizing work zones of usual durations

    • Zero crashes within work zone(!)

    • Bridge built away from traffic with better worker safety and productivity.

    • One statistical surprise – Slightly more accidents after construction over.


Public Support for ABC

Public Overall Satisfaction With Project Results

(1 = not satisfied, 7 = very satisfied)
