An independent 36km freight line running adjacent
to the existing commuter line.
independent 36km freight line running adjacent to the existing commuter line,
known as the SSFL – Southern Sydney Freight Line. Construction of this project
would enable the passenger and freight services to operate independently.
Being in the rail
corridor, there was a vast array of underground services. Geo Image was also
continuously working in very close proximity to the existing commuter line,
major overhead wiring, and all existing infrastructure, Gantries, signalling
Before commencement of the project, a Topographical Survey was undertaken as the
initial survey was by photogrammetry. By using 12d, they were able to create
instant Cross/Long Sections in relation to the design and the existing commuter
line throughout the project. In the field, the were able to assign attributes to
the services surveyed for clarification in the office at a later date.
At the end of the first stage of the project, they created a Visualisation using
the design, As-builts, and the general topographical information collected
during the three years.
