Infrastructure

The Wynyard Walk development provides full accessible pedestrian access between Wynyard Station and the new development at Barangaroo. It is expected to accommodate up to 23,000 office workers and up to 33,000 visitors per day. 

The project included a new western entrance to Wynyard Station, a new 3.5 metre by 9-metre wide underground pedestrian link, a new paved pedestrian plaza and pedestrian bridge with lifts and escalators connecting to the Barangaroo development.

MGP were awarded the design and deviation of water mains, sewer mains and storm water mains.

The development of Sydney’s CBD continues to provide the MGP Sydney Water team with interesting site specific challenges. These include dealing with heritage and oversized critical assets that require protection, whilst enabling new developments to be constructed and the CBD to grow.

MGP designed the Sydney Water infrastructure for the development of Pitt Street metro station.

The project involved a detailed major works design, building plan approval over/near heritage assets, tunnelling, deep basement excavations and anchoring.

Site challenges/solutions: Heritage assets surrounding the development needed to be protected from the construction works such as tunnelling, deep basement excavations and anchoring, our building plan approval assessment ensured all the supportive design documentation and correct construction approach was taken to ensure these risks were mitigated.

Additionally, the new Pitt Street Station will require construction work at each underground station entry, with the construction implemented in two (2) stages. MGP managed five (5) Development Applications with Sydney Water to attain the required certificates, approvals and protect the assets at each stage accordingly.

This in depth approval and connection schedule was implemented to ensure a successful delivery of the project.
