Yandi Sustaining Project, Pilbara , Western Australia
During my time at Land Surveys, I worked on the Rio Tinto’s Yandi Sustaining Project.
The main contractor was Civmec, who was awarded the full civil and concrete package.
This included all earth works and concrete works to all the different areas around the mine site. Including foundation and slabs for a new primary crusher, transfer station, 2 no. surge bin’s , overland conveyor, new wet plant, tailings thickener, scrubber and screener, and over 5km in conveyors.
This also involved high accuracy of setting out of fixed bolts demanded on most footings throughout the job and working with only 1mm of tolerance per 5metres whilst setting out the new stacker rail alignment.

MIG are a sub-contractor to B Jeffreys who was awarded the full package of delivering 98m of large concrete pipework to fix an ongoing problem with poor ground conditions.
To ensure the pipeline will not collapse this time, 50x450mm reinforced concrete piles have been drilled into various positions to enable 350mm thick ground beams have sufficient foundations to stabilise the pipework.
Due to the poor ground conditions over 200m of Larsson piles have been drilled into position to construct a temporary cofferdam to enable works 6 metres deep.
High risk activities lie on this job as it is so close to the water course and a medium pressure gas main travels through the site. MIG are helping with all the engineering services on this job as well as supporting the site management team with RAMS, Supervision and Quality Assurance.
