UGL has won a $740 million contract for the structural, mechanical, and piping construction on the Ichthys LNG project in Darwin.
It comes just days after Monadelphous wins a massive $680 million contract for mechanical works at the site's onshore LNG facilities.
UGL's contract, which will be operated by its joint venture UGL Kentz partnership, was awarded by JKC Australia, which is responsible for the engineering, procurement, and construction of Ichthys' onshore LNG facilties.
The work includes services for the "site wide installation for process trains and additional pre-commissioning and commissioning expertise," UGL said in a company statement.
Work will begin in August, and is slated to be completed before start-up of the second LNG train.
It will provide more than 900 jobs for construction personnel in the Northern Territory.
"We are very proud to have been selected by JKC to participate in the construction of one of Australia's most significant LNG developments," UGL managing director Richard Leupen said.
"We look forward to partnering with Kentz and combining our skills to execute this world-class project."
