COS TUNNEL EXTENSION

Home / Projects / COS Tunnel Extension

Doolee Construction was engaged to install the TechSpan arches as part of our civil and concrete scope for our client in the Pilbara. These arches are capable of carrying extreme loads and are an ideal solution for tunnels and other applications where clearance is needed. Great reports from site on the installation timeframes and safety displayed by our team.

Works included the following:

  • Supply and installation of base slab to support techspan arches.
  • Installation of techspan arches
  • Backfill around arches
  • Installation of bollards and other protective items
