SYDNEY-BASED Australian contractor MGI's new Soilmec truckmounted T108 piling rig has been busy since it arrived in October.
The machine made its debut at the Sydney Institute in Ultimo, where it drilled several 450mm diameter and six 1,200mm diameter piles - all requiring 6m deep sockets in class 3 sandstone.
It then moved to the nearby Westpoint Shopping Centre in Blacktown, where it bored 750mm and 1,200mm diameter, 6m deep piles for an access ramp to the top deck of the car park. Work took three night shifts.
The rig was then off to Wattle Street, Ultimo, where eight 450mm shafts were drilled and cased through fill material and sandstone bedrock to reach the roof of a services tunnel. This was done in a single night shift.
