Redcliffe Community Zone
With the construction of the 150m-long, 25m-wide and 1.5m-deep base slab complete, preparation works continue for the arrival of the TBMs. These include 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 to where the cutterhead is to be lined up for the next section of tunnelling.
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. An 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.
Of the 20 columns being constructed throughout the station to support the ground slab above, twelve have been completed and another eight are scheduled to be cast after the TBMs have left the station box.
Around February/March works will commence at the site located behind Central Avenue and Second Street homes, with a new boundary fence and the foundations of the car park to take approximately three months to complete. The finishing touches (line markings and landscaping) will not be completed until later in the construction program. In the meantime, the area will continue to be fenced off, as it currently is, and used as a laydown area when required.
