Sydney Metro City and Southwest – Central Station Main Works

The Project collectively supported the project’s energy sustainability criteria, emphasizing longevity, efficiency, and reduced environmental impact across its lifecycle. The Project focused on key aspects: 

• Solar PV System: Upgraded to a 25-year design life with high efficiency panels, ensuring long-term energy generation. 

• Integrated Grid decarbonisation into both base case and actual operations models, ensuring consistency in emissions factors and contributing to overall reductions in carbon footprint. 

• Streamlined construction duration to 58 months to ensure operational efficiency. 

• Transitioned to permanent renewable electricity sources by April 2023, minimizing fossil fuel consumption and enhancing site sustainability. 

• As a result, the project achieved a reduction of 31.9%. 

The Project implemented efficient water management practices and optimized water usage across different phases. Some of the key initiatives are: 

- Non-potable water sources were effectively utilized, reducing reliance on potable water and minimizing environmental impact. 

- Robust methodologies were employed to calculate water usage accurately, even in cases where meter readings were unavailable, ensuring transparency in reporting. 

- Continuous improvement efforts included reviewing and updating formulas and calculations in the water balance model to maintain consistency and align with sustainability goals. 

As a result, the Project achieved a significant 24.6% reduction in water consumption compared to the base case, demonstrating a strong commitment to sustainable water management and environmental stewardship. 

The project successfully integrated community heritage values through the following initiatives: 

- Consultation and Engagement: Engaged with Aboriginal stakeholders through formal consultation processes led by Dr. Sandra Wallace, gathering cultural knowledge and feedback on heritage impacts. 

- Managed an 18-month excavation at the former Devonshire Street Cemetery, preserving Aboriginal and European artefacts and human remains with care. 

- Interpretation and Recognition: Integrated identified heritage values into the project's interpretation plan, acknowledging the area's historical significance as a cultural corridor and gathering place for Aboriginal communities. 

These initiatives underscore the project's commitment to respecting and incorporating community heritage values, ensuring their preservation and meaningful inclusion in project planning and execution. 

The ‘Return and Donate’ initiative implemented on site by the project with the help of Citizen Blue is transforming the waste market in NSW by promoting personal recycling practices, reducing waste, and simultaneously supporting local charities.

GECA for Waste Collection Service standard is a process, that results in a new approach in improving supply chains. Overall, the certification helped create change in the broader construction marketplace by presenting the benefits in improving the sustainability credentials of waste collection services which can also be applied to other industries.
