Douglas Partners is proud to provide specialist engineering services during the feasibility, design, construction and operations phases of all modes of transportation systems:

  • Roads and Highways
  • Railways
  • Mass Transit
  • Airports
  • Marine Transport and Ports

We have completed more than 80,000 projects and have delivered many successful projects Australia wide for both private and publicly listed companies, governments, and transportation agencies.

We help our transportation clients identify, mitigate and manage risk, including ground engineering risk, environmental and financial risk, with services such as environmental impact assessments, tunnelling and rock engineering, geotechnical and pavement engineering, environmental monitoring and, construction inspection and testing. Our goal is to improve project cost-effectiveness, reduce operating costs, optimise sustainability, and enhance human health, social and environmental compatibility.


Transport Project Profile: Boggo Road Busway Tunnel Project

Douglas Partners was engaged to undertake the geotechnical investigation and interpretative reporting for Stages 1 to 3 of the Boggo Road Busway Tunnel between the South-East Freeway at Buranda and the Eleanor Schonell Bridge at Dutton Park.

The Busway Project included a combination of cut-and-cover tunnels beneath the South-East Freeway and QR corridors, viaduct structures over arterial roads and the Princess Alexandra Hospital grounds, a reinforced earth wall in Dutton Park, a 480m driven tunnel section beneath the heritage-listed Boggo Road Gaol, and a 10m high soil nail wall at Outlook Park on the perimeter of the Boggo Road Urban Village.
Douglas Partners’ contributions to the project included:
  • Geotechnical investigation, laboratory testing and interpretative reporting;
  • Assistance in developing the spatial model of subsurface conditions for the driven tunnel section beneath the Boggo Road Gaol;
  • Finite element modelling of the soil nail wall;
  • Stability assessment of soil nail wall panels directly beneath the rail tracks in between the contiguous pile walls;
  • Stability assessment of the reinforced earth wall in Dutton Park;
  • On-site construction supervision of pile excavations and soil nail installations;
  • Geotechnical advice on short term stability of batter excavations and trench stability for services installation and personnel entry; and
  • Earthworks testing and supervision services.
