SYDNEY METRO NORTHWEST TUNNELS AND STATION CIVIL WORKS PROJECT
The $1.15-billion Tunnels and Station Civil Works contract was completed in June 2016. The project is part of the first stage of the Sydney Metro (formerly the North West Rail Link) — Australia's largest public transport infrastructure project.
The scope included 15-kilometre twin tunnels between Bella Vista and Epping and civil works for five new stations, two services facilities and a rail crossover cavern at Castle Hill.
JAGCON's skilled contractors helped prepare the successful tender to design and construct the tunnels and station civil works.Our methods and planning engineer was responsible for:
- Planning and methodology for station construction, mined tunnels and
- site establishment
- Liaising with designers to ensure key design deliverables were met
- Providing all construction inputs for developing the bid.
- Developing preliminary designs
- Drafting early works designs
- Supporting the construction team
- Preparing bid documents.
A JAGCON project manager also oversaw start-up of operations at the facility which rapidly went on to successfully meet production targets. This ensured a stockpile of segments was ready for the start of tunnelling and then a constant supply to feed the four tunnel boring machines when they excavated faster than expected.
Under the project manager's leadership there was a strong focus on safety, teamwork and streamlined processes which resulted in a high-performance culture. The facility was officially recognised as having the best segment production rate in the world with an extremely low defect rate.
