Twin Ports Interchange – D1

  • Prepared 3D models of existing and proposed bridge foundations allowing the team to test staging concepts
  • Load Transfer Platform replaced expensive land bridges and avoided contaminated soil

TH 71 Bemidji Full Depth Reclamation – D2

  • Used techniques developed on I-35E MnPASS DB to get highly accurate surveys to design a milling profile which reduced construction change orders that are common on full depth reclamation
