The Client
A Landmark Presence in the Heart of Perth
The client is the building owner group of the South 32/Bankwest Tower, one of Perth CBD’s most prominent commercial high-rises. With a longstanding presence in the city skyline, the tower plays a vital role in hosting major commercial tenants.
Decades-Long Partnership
Envar has maintained a trusted relationship with this client for over 20 years, delivering multiple successful projects across the building, including a long-term maintenance contract. The central plant upgrade marked a continuation of this collaborative history, reinforcing Envar’s commitment to performance, reliability, and client satisfaction.
What we achieved with our customer
The South 32/Bankwest Tower project involved the removal and replacement of critical HVAC infrastructure on Level 48 of the building. This entailed demolition of three existing chillers and the strategic installation of six new water-cooled chillers, cooling towers, a heating water riser, and natural gas-fired boilers.
To overcome the logistical complexity of moving heavy plant to and from Level 48, Envar designed and installed a custom external lifting platform. This bespoke solution enabled safe and efficient transportation of equipment and materials without interfering with building operations. As part of this process, a section of the external wall was temporarily removed and later reinstated with engineering precision.
Despite the scale and visibility of the project, all works were completed while the building remained fully operational. HVAC services experienced zero disruption, reflecting the extensive planning and execution discipline of Envar’s team. All lifting operations, demolition, and installations were scheduled and staged to minimise risk and avoid tenant impact.
The result was a modernised plant room delivering higher system efficiency and reduced reactive maintenance. The project reinforced Envar’s capabilities in delivering high-impact engineering outcomes in live, high-rise environments under tight logistical constraints.
