Chatswood Transport Interchange

New South Wales, Australia

Bassett Acoustics was engaged by Transport Infrastructure Corporation (TIDC) and CRI to provide acoustics and vibration services for the Chatswood Transport Interchange in Sydney. The scope of services for the project included structural dynamics, dynamic finite element modelling, environmental noise monitoring, noise and vibration modelling, and audio system design.

The Chatswood Transport Interchange is a residential and retail airspace development above the Chatswood Rail Station, approximately 10km north of the Sydney central business district. The retail component comprises three levels of food and convenience retail, which surrounds the centrally located station and paid concourse.

The residential component comprises approximately 500 units in three high rise towers. The development will capture the property value created by the connection of the new Epping to Chatswood Line into the existing North Shore Line at Chatswood.

The project is being delivered as a Public-Private Partnership (PPP), and is currently the largest PPP in New South Wales.

Bassett Acoustics, in association with Wilson Ihrig of Oakland, California, as a subconsultant, has several key roles in the project:
Design of structure-borne rail noise and vibration isolation systems
Modelling and design of reduction measures for airborne rail noise
Modelling and design of reduction measures for airborne mechanical plant noise
Public address system design
Internal noise and reverberation control acoustics
Construction noise, vibration, and air quality monitoring

A major project challenge is the design of an isolation system to reduce structure-borne noise and vibration. One of the residential towers is located directly over the rail lines, which are in turn supported on a slab on columns. This configuration means that structure-borne noise and vibration in the tower is of paramount concern.

A track isolation system consisting of discontinuous double-tie floating slabs supported on rubber pads, and resilient rail fasteners, was designed using various Finite Element Models implemented in NE Nastran. The design fits within tight space constraints, and achieves the stringent structure-borne noise criterion in the residential units.
