Sydney Metro Northwest - Castle Hill Cavern
Sydney,
Australia
The $8.3billion North West Rail Link project is the longest transport tunnelling project in Australia’s history and is expected to be complete by 2019. The 15 km long twin tunnels are being constructed to connect Sydney’s northwest suburbs to the city for the very first time.

Impressions from the project process
The use of a custom designed and load-optimized formwork carriage results in the simple operation and movement of the large 330m² unit.

The hydraulically operated carriage allows the tunnel formwork system to vary heights as required. (Photo: Images courtesy of TfNSW)
The PERI Flex scaffold system offers the possibility of having access to the site that is quick and easy to erect whilst integrating high leg-load shoring.
Project-related solutions to provide a safe working platform for formwork setting and concrete pouring operations.
Combined use of the VARIO, SB and MULTIPROPS systems was chosen to restrain the high concrete pressure generated when pouring the nozzles walls.

The assistance provided by PERI in coordinating the design requirements, the methodology and subcontractor suggestions, was integral to the success of the project. When assembled onsite the mechanical nature of the form removed many manual handling and work at height risks, whilst the drive units allowed the unit to be propelled in a safe and timely manner, allowing further safety and program improvements.
