Project outline
The Gudai-Darri (Koodaideri) Rail project consisted of 170 km of railway line connecting the Gudai-Darri mine to Rio Tinto’s existing rail system. The mine is located in the Pilbara, WA.
Scope of works:
Our scope of works consisted of the on-site production of 4,300 tonnes of HPL PE-coated Stilcor CSP culverts, ranging diameter from 600 to 2,700mm. Two pipe mills were deployed on-site simultaneously to service both the Northern and Southern sections of the project. Both sections were completed on time and without incident.
The HPL PE-coated steel was specified for its considerable durability and high resistance to abrasion, with a tested life-expectancy in excess of 100 years. Extensive testing was carried out to ensure the material met with Rio’s requirements.
The project was a first for Roundel in terms of the on-site manufacture of PE-coated steel.
To ensure the timely supply of culverts to the numerous installation crews, located
throughout the chainage, we simultaneously ran two on-site mills across 7 locations, over
a five-month period. The project was completed on time and without incident.
The manufacture of the HPL culverts was to AS / NZS2041.4 standards. The design &
manufacture of the CSP culverts and the B381 bolted structures was to AS / NZS2041
standards. Roundel is the only Australian company offering the design & manufacture of
corrugated metal pipes, and bolted, corrugated metal structures, operating nation-wide.
