well in order to make plans go through,you have to submit a DA which consist of about 4 stages .These stages take a while to go through,I believe the jones project would be a different project as it consist of taking over public space as opposed to refurbishment of building 10.DA s take an awful lot of time to complete ,most of the cbd buildings take between 3 to 5 years to complete the DA.From what I've heard the DA is expected to be complete this year and construction to start next year.
Oh and the planned residential tower block neighbouring might not go head since labour won the election,but a further 18 skyscrapers will be built side by side along the bangaroo site (near the harbor bridge)with the highest being 185 m
this site gives you a good idea about construction around UTS
