Construction update - October 2018
The Bulimba Creek Stage 2 Sewer Upgrade is nearing completion, with 4.25km of the new trunk sewer installed. Tunnelling is complete and construction of maintenance holes is underway or nearing completion along the alignment. Work in all locations is expected to be completed by March 2019, subject to weather and site conditions.
Location: Corner of Ewer Street and Scrub Road
A partial road closure will be in place from late August for about 12 weeks while the final phase of work is completed at Ewer Street (subject to site and weather conditions). Work has been completed over the past two months to grout the new pipe in place.
What happens next?
Work will start from mid-October to convert the 48m deep shaft to a permanent maintenance hole, which is expected to take up to five weeks to construct. This activity will require the use of large cranes, concrete pumps and trucks while the pre-cast maintenance hole is installed, after which the lid will be put in place.
Working hours: Monday to Saturday between 6.30am and 6.30pm
Following construction, Ewer Street will be opened to two way traffic and final restoration is expected to commence around mid-to-late November
. This will involve changed traffic conditions at various times for road resurfacing, traffic island works and line marking for up to four weeks.
Location: Corner of Pine Mountain and Scrub Roads
Construction of the maintenance hole at Pine Mountain Road will re-commence from mid-October for up to five weeks (subject to weather and site conditions). The work involves installing sections of a pre-cast maintenance hole liner in the 15m deep shaft, which will be concreted in place before installing a lid to cover the opening.
The site will be accessed Monday to Saturday between 6.30am and 6.30pm.
Following construction, restoration is expected to commence in November and will involve laying new turf, installing bollards and reinstating the shared footpath/bikeway. We are also partnering with the Bulimba Creek Catchment Coordinating Committee (B4C) to ensure suitable offset planting in approved areas following the work, in line with Council requirements.
Location: 110 Scrub Road (near the Energex substation)
Construction of the new sewer from 110 Scrub Road to Settlers Street Park is complete and the tunnel boring machine (TBM) was extracted in late October.
Working hours: 24 hrs, 6 days from 6am Monday to 6pm Saturday while crews strip equipment out of the tunnel and grout the pipe in place until late November (up to five weeks).
Once the tunnel stripping and grouting are completed, day work will continue from Monday to Saturday between 6.30am and 6.30pm to convert the shaft to a maintenance hole. Construction is expected to take up to five weeks, subject to weather and ground conditions, and involves large cranes, excavators, concrete pumps and trucks. Restoration of affected areas will follow in early 2019.
What to expect
Construction noise, vehicles and equipment, changed traffic conditions, safety lighting and some dust can be expected. A noise reduction wall has been installed around the worksite and noise suppression barriers placed around plant equipment where possible.
Location: Settlers Street Park and Cadogan Street
Our contractor has installed 300m of new pipe and commenced construction of three large maintenance holes in Settlers Street Park and Carindale Reserve.
Working hours: Monday to Saturday between 6.30am and 6.30pm
Work at this location involves:
- setting up a worksite and compound just north of Settlers Street in the park and off Cadogan Street in Carindale Reserve
- constructing a temporary access track from Settlers Street into the park
- constructing a permanent access track from Cadogan Street into the park to allow for future maintenance access
- open trenching between Settlers Street Park and Cadogan Street to install 300m of new sewer pipe across Bulimba Creek, including piling to support the pipe
- temporary partial damming of Bulimba Creek to install support piles and the sewer pipe. This will be done in stages to ensure creek flows are maintained at all times
- tunnelling 754m underground between 110 Scrub Road and Settlers Street Park
- constructing an exit shaft to extract the tunnel boring machine in Settlers Street Park
- constructing three large sewer maintenance holes along the pipe alignment in the park
- completing tie-in works to connect the new sewer pipe to the existing network in Carindale Reserve
What to expect
Construction noise, vehicles and equipment, changed traffic conditions and some dust can be expected. Some vegetation will be cleared and any trees marked with 'R' will be removed in accordance with approved Council permits.

What have we done so far?
Since August 2016, the project team has:
- constructed two tunnel boring machine exit shafts, one in Edwards Reserve off Tones Road, Mansfield and another on the corner of Ewer Street and Scrub Road, Carindale. The Ewer Street shaft is an impressive 48m deep and took six months to construct
- constructed three tunnel boring machine entry shafts, one on the Allen Innes Oval off Tones Road in Mansfield, one on the corner of Pine Mountain and Scrub Roads in Carindale and one on Scrub Road closest 110 Scrub Road Carindale
- tunnelled 582m between the Allen Innes Oval entry shaft and the Edwards Reserve exit shaft
- tunnelled 852m between the entry shaft on the corner of Pine Mountain and Scrub Roads to the exit shaft in Edwards Reserve
- tunnelled 700m between the entry shaft on the corner of Pine Mountain and Scrub Roads to the exit shaft on the corner of Ewer Street and Scrub Road
- tunnelled 802m between the entry shaft at 110 Scrub Road to the exit shaft on the corner of Ewer Street
- prepared the TBM retrieval site at Settlers Street Park
- tunnelled 700m north from the shaft at 110 Scrub Road to Settlers Street Park
- open trenched 300m of sewer pipe in Settlers Street Park, Carindale and across Bulimba Creek
- installed a new sewer pipe along the edge of the Allen Innes Oval off Wecker Road, Mansfield
- constructed a shaft and converted it to a maintenance hole in Edwards Reserve, off Tones road
- constructed two maintenance holes along the creek side of the Allen Innes Oval off Wecker Road, Mansfield.
- constructed a pedestrian footpath to enable access from Greendale Way across Scrub Road onto Pine Mountain Road.
Over the coming months we will be:
- stripping and grouting the tunnel between 110 Scrub Rd and Settlers St Park
- converting the shafts at Ewer Street, Pine Mountain Road and 110 Scrub Road to permanent sewer maintenance holes
- constructing two large maintenance holes in Settlers Street Park and one in parkland off Cadogan Street, Carindale
- connecting the new sewer into the existing network at either end of the alignment
- restoring areas affected by our works as construction is completed
