24-hour tunneling works to commence 19 February 2019

Essential services work to install a sewer main from Queens Wharf Rd to North Quay will begin 24-hour work seven days a week.


From Tuesday 19 February 2019 until Monday 30 September 2019, work will occur 24-hours per day, seven days a week to installation a sewer main that will service the future Queen’s Wharf and Brisbane CBD needs.


The sewer will be installed from Queens Wharf Road and link up with the existing Queensland Urban Utilities sewer near the intersection of North Quay and Turbot Street. See attached map for details.

What to expect:

Due to the depth of the sewer below ground level, the sewer infrastructure will be installed using a tunnel boring machine (TBM). This construction methodology will also minimise construction related impacts on near neighbours and the environment.

Equipment used will include a tunnel boring machine (below ground), gantry crane, lifting equipment, generators, flood lights, hydraulic tools and industrial fans.

Vibration and ground movement:

TBMs are very good at reducing vibration so people living or working above the tunneling area may not notice what is happening beneath the ground.

The above ground impact will vary depending on the geology of the area, depth of the tunnel and the type of buildings above, however latest technology in machines allows operators to better minimise and mitigate against any above ground disturbance.

Noise from above and below ground:

Strict controls are in place to make sure construction noise is well managed and complies with EPA guidelines. A range of measures will be used to minimise noise impacts from tunneling and these include:

  • Adopt best practice site management to reduce noise from work areas
  • Where possible, plan noisy works at times when they will cause the least inconvenience

Monitor noise levels and take action to reduce noise if necessary.
