Project Description:
Qantas Terminal 3 (T3) at Sydney Domestic Airport is one of the busiest and most significant terminals for domestic flights in Australia. Exclusively used by Qantas and its regional subsidiary, QantasLink, it serves as both a hub for the airline and a key gateway for millions of domestic travellers. Located at Sydney Airport, one of the busiest airports in the Southern Hemisphere, T3 is strategically positioned near the other terminals, facilitating smooth transfers between domestic and international flights.
The terminal is equipped with various amenities, including multiple check-in counters, self-service kiosks, a dedicated Qantas lounge, retail shops, and dining options to enhance the passenger experience. Recent upgrades, such as the chiller and cooling tower system improvements, are part of ongoing efforts to modernise facilities and ensure operational efficiency, especially as passenger volumes continue to rise.
Kerfoot played a key role in these upgrades, particularly in the mechanical and electrical systems, which involved intricate tasks like installing new systems and coordinating with other trades to minimise disruptions to daily flight operations. These renovations aim to keep T3’s infrastructure energy-efficient, sustainable, and capable of meeting future demands while maintaining high security standards and a seamless travel experience for passengers.
Specific items within the scope of this project were:
- Testing & Investigation of Existing Services
- Switchboard Upgrades & Replacement
- Submains & Busduct Installation
- Electrical Distribution Upgrades
- Chilled Water Plant Upgrade
- Mechanical Pipework Modifications
- BMCS Expansion & Optimisation
- Energy & Water Metering
- Generator & Automatic Transfer Switch (ATS)
- Fire & Life Safety Upgrades
- Staged Delivery in Live Environment
