Following the removal of the slurry treatment plant, which was necessary to process spoil excavated by the two tunnel boring machines, works are underway to break up the concrete pad the plant and associated infrastructure were located on. Neighbouring residents may experience a thumping noise coming from site. Works will take place intermittently during usual operating hours (7am to 7pm) over a period of six weeks and are scheduled to be completed by the end of November.
At the station crews are adding final touches. The distinctive station roof has been fully installed and will be visible from surrounding areas and clearly identify the entry point to the station. The two lift shafts have had glazing installed, and the assembly of the lift cabins is complete. Escalator fit-out also finalised.
Outside the station installation of the 626 solar panels is more than 30 per cent complete. The system is designed to generate enough electricity to meet the average summertime daytime power demand of all three new stations.
The construction of the multi-deck car park at the northern end of site is in full swing. Ground level footings and columns are in place, and about 75 per cent of the hollow core beams to support the first level have been installed. Concrete pours to complete this level will be ongoing until the end of the year. Crews have also made a start on the columns supporting level two of the structure, with 35 poured and curing. Once complete, the three-level building will accommodate 1200 vehicles and more than 50 motorcycle bays. Parking will be available to Transperth patrons at a cost of two dollars per 24-hour period.
Backfilling of the station precinct is also ongoing with about 40,000 of 60,000 cubic metres of soil placed. This is necessary to bring the station entry to final level.
