CloseThe Project Alliance Agreement (delivery contract) was signed in April 2025. We aim to begin main construction later this year, following site establishment in September 2025.
Until then, we’ll continue to finalise the detailed design alongside early works (e.g. demolition, ground investigations, etc.).
Further updates will be provided closer to construction starting.
