Bridge Optimisation

Bridge optimisation: reducing cost without reducing safety

Many bridges are over-designed because options were not compared early. Optimisation looks for savings in the elements that drive cost most.

Where savings come from

  • Fewer or longer spans to reduce piers in water
  • Standard precast girders instead of custom sections
  • Foundations matched to real ground conditions
  • Integral abutments that remove bearings and joints
  • Approach ramps with ground improvement instead of long structures

Safety stays fixed

Optimisation changes the solution, not the design standard. Every option is checked to the same loads and code requirements.
