Cul,

Check out this 2014 Aeronatutical Assessment for 505-523 George Street:

http://www.cityofsydney.nsw.gov.au/_...ACHMENTA12.PDF

Pertinent points:

Quote:
The other facet of the Airports Regulations refers to PANS-OPS “surfaces”. These surfaces are complex in nature and protect aircraft operations in all weather. Calculations in an appendix to this document indicate that these surfaces would not be infringed by the proposed tower building envelope of 278.4m. However, consideration will need to be given to keeping the cranes required to construct the building beneath a maximum limit of 310m AHD which is imposed by the current PANS-OPS surfaces. A commitment to this effect would be required as part of the airspace height application for the development.
Quote:
While a building of 278.4m would be beneath or outside all surfaces, cranes required to construct the proposed building would probably not be beneath all surfaces. The maximum height allowed by the Missed Approach associated with the RWY 34R ILS approaches is only 310m. While the regulations allow temporary penetration (up to three months) of this surface, the current attitude of CASA, Sydney Airport and the Department to such temporary penetrations is likely to mean that obtaining approval for cranes greater than 310m will not be possible.
The current envelope for 505 George is fine. Usage of a hammerhead crane (at 290m RL) would help help keep 505 George under the 310m RL hard limit.

No doubt there are complications with going tall in regards crane penetration & radar in Sydney, plus it appears the surface limits are extremely complicated, likely multiple non-flat surfaces with many intersections.

Somewhat closer to Circular Quay the easier to go taller I would suggest. If I was king I would just add an architectural feature / pointy top to Lend Lease's CQ tower and call it a supertall

Rialto Towers is in the 150,000sqm range for GFA (from memory).

EDIT: 146,786sqm:

I think the ANZ Headquarters in Docklands is one of the biggest but when a building is only 10 stories we tend to ignore it ? Damn the fashion of Campus !

Yes 182george is that tower starting in couple of months. In 2021 will be tallest office tower in Australia finally taking Rialtos 35year reign since 1986. But it will still have 7 less floors then rialtos 63

Ashame Aspire isn't going 300 like the original evelope. Getting sick of CASA's bs though, preventing 505 from really going at a breakout height.

Yes, that will be extremely significant tower.

When will we be getting news and action of 505G? It has been kicking along for years.

Laurence Dragomir over at Urban Melbourne penned a great article noting the ever expanding amount of office construction in the central Melbourne area.

IS 2018 THE YEAR OF COMMERCIAL FOR THE MELBOURNE MARKET?

Nothing over 200m sadly, but still some big ones such as 80 Collins (187m) and 311 Spencer (171m).

Unsure if db2 has shared this 80 Collins St content on this board?

The diamond cut facade looks like it will have embedded LEDs for a great night time show:
