Construction firm Leighton Holdings has landed contracts worth $1.2 billion for the Darwin Ichthys LNG project.
The company has won a $923 million contract to help build onshore liquefied natural gas (LNG) facilities at Blaydin Point in Darwin, as well as a four-year $280 million operations and maintenance contract for the same project.
Leighton says the new work takes its total oil and gas contracts to more than $4.5 billion.
The building firm will be responsible for the main civil infrastructure require, including pilings, foundations, trenching for pipes, cables sewers and drainage, roads, paving, electrical and instrumentation cabling.
Craig Laslett, the managing director of Leighton Contractors says the new contracts build on an existing relationship with the lead contractor for Ichthys.
"Leighton Contractors looks forward to continuing our relationship with JKC, and delivering our third contract as part of the multi-billion dollar Ichthys Project," he said in a statement.
"We are committed to delivering this onshore infrastructure with certainty and to the highest quality while maximising the opportunities for the local workforce and businesses."
Leighton says around 3.5 million man-hours will be needed for the project, with a peak workforce of more than 900 people.
"We will provide Darwin's local workforce and businesses with as many opportunities as possible to capitalise on the delivery of this world-class infrastructure, and support the growth of its skills base and experience for the benefit of future development in the region," Mr Laslett added.
Leighton shares showed little reaction to the news, rising 0.6 per cent to $17.95, in line with the broader market's 0.6 per cent gain.
