Quay Quarter Tower Riser
Back
Location: Sydney, New South Wales
Client: Equilibrium & Climatech JV Pty Ltd
Scope:
- Modularisation of 200m tall mechanical & hydraulic services riser
- BIM coordination, production of shop drawings complete with lifting plans, material take-offs and cutting lists
- Structural Design & Certification of prefabricated riser and pipework
Design Achievements:
- 12m long modules are self-aligning and stackable to minimise crane time
- Design for safe access enabled installers to enter the riser at each floor during installation without the need for fall-restraint.
- To reduced the pressure thrust loads KUSCH designed the 600mm condenser pipes with double-hinged expansion bellows, to acommodate building and thermal movements
Design Highlights:
- Pre-galvanised modular SUPA framing, to avoid welding and ensure a long service life
Design Considerations:
- Modules were transported horizontally and rotated vertically on site while suspended using two tower cranes.
- The riser modules were fixed to a combination of new and existing concrete, with varying capacities.
- Building movements due to core shortening, along with inter-storey drift
Project Features:
The $1b Quay Quarter Tower refurbishment upcycled the 1976 AMP Centre Tower, and has retained over 65% of the original structure and 95% of the original core. Read more about the project here: https://3xn.com/project/quay-quarter-tower-2
