Melchor were engaged to construct all in-situ concrete works on the Yanchep Rail Extension project.

The Yanchep Rail Extension consists of a 14.5km extension of the Joondalup Line from the existing Butler Station further north to Yanchep. Works include 15 bridges and 3 train stations, these being at Alkimos, Eglinton and Yanchep.

Approximately 30,000 cubic meters of concrete was poured over a period of 24 months. This equates to approximately 5,550 tonnes of steel reinforcement.

The project works consist of:

• bottom-up bridges
• top-down bridges
• piles up to 12m in depth
• post-tensioning works
• pre-cast concrete installation
• large retaining walls (of varying widths, and up to 11 metres in height)
