Geotchnical Aspects of the Eastern Busway and South East Queensland Infrastructure Plan Rail Program Alliance Projects

Patrick Kidd

In May 2007, the Queensland Government updated its $82 billion blueprint for upgrading a range of infrastructure in South East Queensland (SEQ). The South East Queensland Infrastructure Plan 2006-2026 (SEQIP) outlines two decades of development of road, rail, water, energy, health, education and community infrastructure. Of this, $35 billion has been allocated for a roads and transport package for roads, rail, buses, walking and cycling, with a potential additional $15 billion dollars also being considered for transport infrastructure.

Five of the significant SEQIP transport projects that Connell Wagner’s Brisbane Geotechnical section are currently working on are the Eastern Busway and the SEQIP Rail Projects, Robina to Varsity Lakes Rail Extension, Corinda to Darra Third Track, Caboolture to Beerburrum Line, Beerburrum to Landsborough Line. These projects encompass almost 40 km of new rail infrastructure and over 16 km of proposed new busway infrastructure that include large scale earthworks, numerous substantial bridges, tunnels, significant roadworks and station structures.

The presentation will give a brief overview of each of these projects and discuss the aspects of the geotechnical engineering for each of the projects, with a focus on the Eastern Busway and the Robina to Varsity Lakes projects.

Engineers Australia members participating in AGS technical sessions can record attendance on their personal CPD logs. Members should refer to Engineers Australia CPD policy for details on CPD types, requirements and auditing guidelines.
