More tunnelling at Woolloongabba station site

The Cross River project is proceeding apace

TUNNELLING is to continue north and south from the Woolloongabba station site during March.

Activities on the site are to include:

  • TBM 1 Elseexcavation to the northern tunnel portal at Spring Hill
  • Oversized deliveries for TBM 2 Merleassembly
  • TBM 2 Merleexcavation to the northern tunnel portal at Spring Hill
  • Roadheader excavation and controlled blasting in mined tunnels running south from Woolloongabba to the new Boggo Road underground station
  • Conveyor operation for excavated spoil
  • Establishing and mobilising a second tower crane
  • General earthworks and excavation activities, including offsite haulage of excavated material
  • Machinery and equipment deliveries including drill rigs, excavators and tunnelling plant
  • Installing formwork, fixing of reinforcement steel and placing concrete
  • Concrete deliveries, including out-of-hours deliveries to support large continuous concrete pours
  • CCTV inspections and pressure cleaning of water and sewer infrastructure
  • Utility works including installing power and other services for tunnelling and site operations
  • Geotechnical investigations in and around the site, using a truck-mounted drill rig to take samples of ground / soil conditions.

According to Cross River Rail management, potential noise, dust and vibration from onsite construction works may affect neighbours and will be minimised “as much as possible”.

Onsite works include:

  • Operation of TBMs and associated support systems including the spoil conveyor
  • Onsite truck movements to remove the excavated spoil from tunnel excavation
  • Temporary lighting to facilitate out of hours work within the station box and decline.

Other impacts from activities undertaken around the site can be expected from:

  • Increased survey works in the Woolloongabba and Kangaroo Point areas and along the tunnel alignment
  • Continued increase in vehicle, truck and construction worker movements in the area
  • Traffic controller operated boom gates at the Vulture Street and Main Street driveways for improved pedestrian safety
  • Use of survey equipment, vacuum excavation trucks, road saws, small excavators and tipper trucks.

 

“Every effort will be made to minimise disruptions for residents and business in close proximity to the project site” Cross River management said in a statement.

“Work is subject to relevant approvals and suitable weather conditions.”
