Geotechnical investigations

From late February geotechnical investigations will be carried out to identify underground rock and soil conditions along the Cross River Rail tunnel alignment in Kangaroo Point.

The investigations will involve excavating four small boreholes to sample ground conditions along the tunnel alignment.

Each borehole will take approximately four to five days to complete.

Details of work

During this work, activities will include use of vacuum excavation trucks, truck-mounted geotechnical drilling rigs, compressors and lighting towers. Works will not impact on the operation of the cycle and pedestrian paths in the area however there will be occasional minor delays. Signage and traffic control officers will be in place, as required, to guide people safely around the works.

Night works

Due to the location of the boreholes, works will generally occur between 6:00pm and 6:30am, Monday to Saturday, to minimise impacts on access through the area and to maintain the safety of the community and our workers. Some work will be carried out during the day, between 6.30am and 6.30pm. Please see map below for approximate location of the boreholes.

What to expect

  • Workers may arrive onsite one hour prior to the planned start time to prepare for the day’s activities
  • An increase in construction workers and vehicles in the area
  • A potential increase in noise, dust and vibration. These impacts will be reduced as much as possible

Every effort will be made to keep disruption to a minimum for residents and businesses in close proximity to the project site. Work is subject to relevant project approvals and suitable weather conditions.
