Dams

Our civil engineering consulting capability has grown in response to demand for specialist services for infrastructure and land development services.

Tonkin + Taylor has a strong track record in dam design with projects involving concrete and steel structure design, spillways, penstocks, bridges, inlet structures, power stations and CAD design.

Our team is skilled at managing diverse project inputs effectively. You will receive a high level of team commitment, efficiency and productivity.

Expertise

Key capabilities include:

  • Concrete and steel structure design – for example for power stations, spillways, penstocks, bridges and inlet structures
  • Tunnelling design
  • Roading design
  • Drainage design
