Goulburn Street Car Park

The task was to demolish the cavity brick southern wall (5 storeys high and about twice as wide at 37.5m) and erect a steelwork frame to install the largest tri-sign in the Southern Hemisphere.

Special Challenge

  • The demolition, steelwork construction and sign installation were each conducted above the main southern 6 track rail corridor.
  • The work was designed not to interfere with RailCorp train operations except for a very few tasks that had to be completed during rail closure weekends (two) or during gaps between train operations.
  • The busy car park was operational throughout.
  • The car park base structure was rough-hewn and skewed in each plane.
  • Car park structural drawings did not match the car park structure.
  • All work had to comply with stringent WorkCover, Council and RailCorp safety procedures.


Andersal was initially contracted to install a large net consisting of 30 x 1 tonne cables and a mesh net to prevent bricks, concrete or general collapse of the southern wall to the rail tracks below. Andersal was selected because of its’ abseiling expertise, the method it proposed and price.

The main scope of works was to extend the Protective Element (PE), demolish the existing cavity brick wall, construct a steel frame, erect the Prismaflex sign, erect the cladding and then remove the PE. A new partition wall was constructed on each level to separate the car park from access to the sign. The wall and sign were demolished and constructed directly above the main rail corridor between Central Station and the city underground.
