Roundel Civil Products designed, manufactured and supplied ten B200 bolted corrugated steel tunnel structures for the Amrun Haul Road MC10 Stage 3 project at Rio Tinto’s Amrun bauxite operation near Weipa. The structures form part of the civil infrastructure supporting the project’s heavy haul road network in remote Cape York.
Manufacturing the B200 plates in Townsville provided a direct Queensland supply pathway for this Far North Queensland project. The plate built system allowed the structures to be transported in manageable components, delivered progressively and assembled on site in line with the construction sequence.
The completed structures combine the strength of bolted corrugated steel with the flexibility of a modular construction method. Their scale, repeatability and suitability for staged installation made the system well matched to the logistical and programme demands of a remote mine infrastructure project.
Ten large scale tunnel structures were supplied for the MC10 Stage 3 works, demonstrating Roundel’s capability to design and manufacture project specific corrugated steel solutions in North Queensland for delivery to remote and demanding infrastructure sites.
