Company History

Our Expertise

Our expertise and construction knowledge (both conventional and tunneling construction) has seen the company undertake and complete many large projects throughout Australia. On the West Coast we have recently completed the construction of 11km of Infill Sewerage construction for the Water Corporation in Halls Head WA. This project includes a combination of conventional trench excavation and tunnel construction.

On the east coast, the company has recently completed close to 6kms of DN900 on the Gold Coast for BMP Alliance (Tenix/Gold Coast Water), more recently 2kms of DN1200 and DN1400 for Abigroup in Coomera and Pimpama on the Gold Coast, 2kms DN1000 in Toowoomba (Toowoomba CC), 2.7km of DN750/900 in Sydney (UGI/Sydney Water), 1km of DN900 for Thiess / JHG (Airport Link) in Brisbane, multiple drives DN1500 steel enveloper for Northern Networks Alliance, 1km of DN600 for Queensland Urban Utilities and 600m of DN1200 in Sydney (Leighton’s) among other even longer pipeline distance projects.

Some of these projects have required us to undertake deep shaft construction (either via sheet piling or concrete caissons) so as to construct adequate launch and receive pits for the tunneling equipment. More specifically, with regards to concrete caisson sinking, we have the capability of constructing cast in-situ concrete caissons of up to 12m ID. We also possess the capability of constructing up to 9m ID pre cast segmental concrete caissons.

To further emphasize the capabilities of the company, Rob Carr Pty Ltd recently completed a DN1200 project in Coomera for Abigroup & Gold Coast Water involving two rock bores (370m and 270m) and another DN1400 project consisting of three rock bores (266m, 266m and 287m each) with drives leading into a 23m deep shaft constructed by Rob Carr Pty Ltd using pre cast concrete segment linings via underpinned construction. Pre cast concrete segmental shaft construction (via sinking or underpinning methods) is popular in Europe but relatively new to Australia. Rob Carr Pty Ltd was the first contractor in Australia to construct a deep shaft using underpinned pre cast concrete segments.
