Advanced Contracting

  • Identify bridges for early construction/replacement due to poor condition
  • Advanced relocation of utilities

Design to Minimize Future Maintenance

  • Eliminating expansion joints, design for continuity
  • Minimize number of bearings

Erection Methods

  • Self Propelled Modular Transport (SPMT)
  • Roll In
  • High capacity cranes
  • Erection Gantry
