Redcliffe Community Zone
Preparation works continue for the arrival of the TBMs. This includes the construction of in-situ double segment blocks, which will support the TBMs and their 130m-long trailing gantries to be manoeuvred through the station box, and installation of temporary service pipes along the diaphragm walls. The pipes supply water and grout to the TBMs and allow excavated material from tunnelling operations to be channelled back to Forrestfield.
One of the last sets of works to be completed is the installation of the second sealing ring. The rings will assist the TBMs when they are relaunched at the western end of the station box.
Once the TBMs arrive at Redcliffe station they will undergo a five-week maintenance program before they start the final leg of their journey to Bayswater Junction.
The arrival of the TBMs will see some changes in activity at the Redcliffe site. One of the main changes will be the commencement of 24-hour operations. A 32m-high electric tower crane will be used to lower tunnel segments into the station box. Multi-service vehicles (MSVs) will then transport the segments to the TBMs.
Activity is also ongoing at the site behind Central Avenue and Second Street, the location of the future car park. The area has been completely cleared of all vegetation and debris allowing for backfilling to pavement level. Drainage works for the car park have commenced and asphalting will be the next major set of works to follow.
The car park will be used as a lay-down area until it is officially opened. The finishing touches, such as line markings and landscaping, will not be completed until later in the construction program.
