Excavation kick starts Parkville Station construction
Excavation has commenced at the Parkville worksite as workers dig out the equivalent of 80 Olympic swimming pools worth of rock and soil to build the new Parkville Station.
Crews are digging the 270-metre long and 30-metre-wide station box around 30 metres below Grattan, between Leicester Street and Royal Parade.
Once the excavation reaches 15 metres, gantry cranes will replace trucks and be used to lower buckets to collect rock and soil. The cranes will then lower excavated materials onto trucks inside two acoustic enclosures, before the trucks exit the site.
The first of three 20-metre gantry cranes have been installed over the site to assist with the removal of up to 35 tonnes of rock and soil at a time, and lower construction equipment and materials into the excavated space. All three cranes will be installed by the end of February 2019.
Excavation will continue until the end of this year, with around 200,000 cubic metres of rock and soil to be removed from the site. Once complete, station constructions and fit-out will continue underground.
