Building Responsibly in Ultimo
DigiCo is expanding its existing SYD1 data centre at 400 Harris Street, Ultimo, making efficient use of established infrastructure to help meet Sydney’s growing need for digital connectivity. DigiCo and SHAPE are committed to delivering the project responsibly, maintaining open communication and working closely with the local community throughout construction.
This website has been created to keep residents, businesses and stakeholders informed about the project and the measures being taken to manage local impacts. Here you can access construction updates, environmental monitoring information and project resources, as well as contact our dedicated community team with any questions, feedback or concerns.
Our goal is to ensure the project is delivered with a strong focus on transparency, environmental performance and consideration for the surrounding community as we continue to support Sydney’s growing digital needs.
