Built in 2005 as a commercial office development with lower level retail, the skyvue building runs directly above four active railway tunnels in Sydney’s busy CBD. It was identified that without effective isolation of the ground-borne vibration generated by the trains running through the tunnel, unacceptable levels of noise would occur inside the building.
Heggies, the acoustic consultants engaged by Grocon Constructors, carried out extensive testing and modeling, and specified Embelton Multiplate Rubber Bearings to effectively isolate the ground borne vibration.
Embelton supplied 24 pre-compressed lateral bearings and 244 vertically loaded bearings with static deflection of 7-9mm under load. Each bearing was individually tested to 150% of its working load before installation, and compliance testing after the building was completed showed an excellent correlation between the noise levels predicted in the testing stage.
