The legacy of geotechnical information from the Brisbane Airport Link and Northern Busway project

The Airport Link and Northern Busway (APLNB) Project in Brisbane, Australia involved the construction of approximately 15km of new tunnels, excavated and constructed with mined, drill & blast, bored and cut & cover methods. Approximately 10 km of the tunneling – including parallel segments running in close horizontal and vertical proximity to one another - were mined through complex geological conditions with up to 17 road-headers operating concurrently. The amount of geotechnical information generated by the APLNB Project from the investigation through to design and construction was colossal. This paper reviews the legacy of geotechnical information from the APLNB project since its tunnels first saw traffic in July 2012. Based on land use planning around infrastructure corridors, the use of tax dollars, sustainability objectives, and a trend towards digital design, it is argued that similar projects should formalise consideration of the long-term value of the geotechnical information that they generate.
