Roma Street station construction update - February 2021

The Roma Street project team has achieved a major milestone with the demolition of the former Brisbane Transit Centre building now complete. The focus now turns to construction of the new buildings, with piling for the new Station Building and excavation of the Services Building underway.

The two roadheaders continue underground with about 155 linear metres of the station cavern now excavated. Underground controlled production blasting in the cavern is ongoing and will occur intermittently until mid-2021, weather and site conditions permitting.

The below works will occur within the standard construction hours of 6:30am to 6:30pm, Monday to Saturday.

Some activities will be completed out of normal construction hours due to traffic permits, safety requirements and construction methodology. Nearby residents will be notified in advance via letterbox drop or a poster in the apartment building mail room.

Site establishment and enabling work

The below demolition works are ongoing and will include:

  • Finalising construction of the site office and amenities facilities at the eastern end of the site
  • Installing a signalised site vehicle access west of Makerston Street. This will involve modifications to the traffic signals and line marking at the intersection of Makerston and Roma Streets, including installing a new signalised pedestrian crossing at the new site access.

Stormwater main relocation work

From February until later March 2021 stormwater main relocation works are required.

These works will include:

  • An existing underground stormwater main service is required to be relocated to outside the excavation area of the new main station building and under Roma Street. Some night and weekend work may be required to complete this work. Further information will be provided in the coming weeks.

Piling

From February until late March 2021, piling works will occur and include:

  • Earthworks to complete the foundation for piling equipment
  • Mobilising additional piling rigs and associated equipment to the work site
  • Installing bored piles for retention of the ground prior to the excavation of the new station building shaft.

Utility work and geotechnical investigations

During February, there will be some works conducted that will involve utility works and geotechnical investigations.

This work involves:

  • Locating, installing and relocating underground utility services on streets surrounding the site
  • Groundwater monitoring and geotechnical investigations
  • Modifying hoarding and overhead gantries along Roma Street

Lane closures and other traffic changes will be required to safely complete this work.

What to expect

  • Construction activity with potential for an increase in noise, dust, vibration, truck movements and workers.
  • Construction impact mitigation activities such as street sweepers, water suppression and hoarding installation.
  • Temporary traffic and pedestrian changes on Roma Street and other surrounding streets.
  • Work is subject to relevant approvals and suitable weather conditions.
