We believe that a focus on planning and optimising processes will ensure a successful delivery.

Tunnelbau provides innovative civil engineering solutions to underground operations.

Based in Sydney, Australia, we have over 22 years experience working on mega tunnelling projects across the globe.

We partner with tier 1 companies and specialized contractors and focus on:

  • Shaft construction eg: blind sinking

  • Trenchless technologies eg: pipe jacking

  • Tunnelling (TBM excavation, roadheader excavation, drill & blast)

  • Desalination plants, dams and pumped hydro

  • Associated civil works (site establishment, pump stations, precast facilities, substations)

With our emphasis on strong leadership and organisational management, we can expertly assist in the planning, preparation, execution and completion of tunnelling works. In addition, we can resolve problems and optimise processes.

Support and advice can be provided at various stages of a project including feasibility studies, tender documentation and evaluation, methodology reviews, value engineering and cost analysis.

During construction, we can provide supervision and project management for all underground engineering requirements.
