Monadelphous has won a $75 million construction contract for BHP's Jimblebar iron ore mine.
According to the contractor it will provide structural, mechanical, and piping works associated with the construction of the stacking, reclaiming, train load out, product sampling, and water infrastructure facilities.
It is scheduled to begin work next month.
BHP has been slowly ramping up its work at Jimblebar.
Two weeks ago it gave UGL a $99.45 million contract to provide the fabrication and installation of equipment associated with coarse ore stockpiles, secondary crushing, scalping and screening, and conveyors.
Last month the miner awarded AusGroup the contract for its plant's inflow circuit, and prior to that gave Downer the contract for the Newman HV Power System Augmentation project that will power Jimblebar.
According to Downer its scope of works included the supply and installation of electrical power and control components for two new substations; modifications on existing substations and transmission lines and the upgrade of network control systems; and the installation of a new 132KV transmission line between the Newman and Jimblebar iron ore mines.
Early last year Thiess was also awarded the contract to actually mine Jimblebar.
While work has been ramping up at the site, it stumbled in June after the CFMEU began investigating worker claims of asbestos contamination, stating that workers may be exposed at the site.
"The mine itself has been made aware; their position on the subject was until they receive confirmation from further testing, they were going to continue to use this," CFMEU safety officer Steve McCann said.
"Now that borders on negligence as far as I'm concerned."
Since the initial announcement of the investigation no further information has been released regarding the alleged contamination.
