Having commenced work on the Fitzroy to Gladstone Pipeline earlier this year, Bothar Boring and Tunnelling has announced the award of further contracts as part of its ongoing collaboration with the McConnell Dowell BMD joint venture. 

Bothar Boring and Tunnelling (Bothar) successfully commenced work on the Fitzroy to Gladstone Pipeline (FGP) earlier this year at Gavial Creek and Bruce Highway.

The company has now announced the award of further significant contracts as part of its ongoing collaboration with the McConnell Dowell BMD joint venture (MBJV).

These additional packages include 18 specialist shafts as well as nine trenchless crossings consisting of AVN1200 micro tunnelling, auger boring, and ‘Bothar Built’ EPB-TBM methodologies.

The ‘Bothar Built’ EPB-TBMs, Earth Pressure Balance Tunnel Boring Machines designed and built in-house, will be pivotal in executing these works. 

Bothar’s innovative approach and technical expertise in tunnel construction have been crucial factors in the expansion of their role in the FGP.

The FGP will connect to GAWB’s existing network in Yarwun, and includes construction of a water treatment plant, reservoirs, and pumping stations along its 117km length. 

This infrastructure will enable long-term water security for GAWB’s customers and for future developments in the region’s renewable industries.

“We look forward to continuing our working relationship with McConnell Dowell BMD Joint Venture to be part of the safe delivery of the FGP,” Bothar general manager David King said. 

“Bothar remains committed to leveraging our extensive experience and innovative technologies to support the growth and sustainability of communities through the FGP, ensuring a legacy of reliability and environmental harmony.”

The company is currently active in all eastern states of Australia and is undergoing a phase of growth and expansion across Australia. This expansion underscores Bothar’s expertise and growing presence in infrastructure development and its ability to stay at the forefront of industry trends.

The company announced the successful completion of its latest project for Entracon Civil at Third Street, Black Rock. 

This project featured 200m of stormwater upgrade in water-charged sand. The company’s expert crew utilised a Herrenknecht AVN400 to navigate these tricky conditions with precision and efficiency. 

Meanwhile, in Northern NSW, Bothar is using a custom-built Open Face TBM to install 68m of DN1500 RCJ stormwater pipe for a rail underbore project. 

The selection of Bothar’s Open Face TBM was due to the mixed ground conditions and the presence of cobblestones and boulders in the area. 

Bothar has also been awarded the trenchless design and construction of three additional stormwater road crossings following the completion of the rail underbore project. 

The continued engagement on subsequent projects highlights Bothar’s reputation for delivering high-quality solutions and their commitment to meeting the evolving needs of their clients in each region.

As Bothar continues to broaden its operations and take on a diverse range of projects, the company is fostering collaborations with a diverse network of stakeholders, enhancing its standing as a reliable and forward-thinking partner.
