The company was awarded a three-year contract with Alcoa of Australia for calciner maintenance, major overhaul and repair services, including scaffolding, mechanical, refractory and electrical services at the Kwinana, Pinjarra and Wagerup refineries.

"We are very pleased to again be trusted by Alcoa of Australia to deliver critical maintenance activities for their calciners across their Western Australian sites," Civmec CEO Patrick Tallon said.

In the manufacturing division, Civmec will complete the supply, manufacture, trial assembly and delivery of four main train load-out bins for BHP's Jimblebar iron ore project, as well as the supply, fabrication, surface treatment and modularisation of shuttle trusses, conveyer trusses, platework and stick steel for Rio Tinto's Gudai-Darri project.

The construction division won a civil package for earthworks, concrete placement, cabling and pipework for a Roy Hill bottlenecking project, as well as the delivery of a fixed plant workshop for the Rio Tinto Mesa A project.

Outside mining, the company also won a contract in Perth for a bridge connecting the Queen Elizabeth II Medical Campus to Kings Park by Main Roads.

Civmec last traded at 42c, valuing the contractor at $210.5 million.
