Carillion, which took over Newcastle’s Warm Front business Eaga in 2011, has signed a £75m contract to deliver the expansion of Liverpool Football Club’s Main Stand and associated improvement works.
The project will add around 8,500 seats and will increase the overall capacity of Anfield Stadium to some 54,000.
Work is expected to start this week and is scheduled for completion in the third quarter of 2016.
The Carillion group is a leading support services company with a portfolio of Public Private Partnership projects and capabilities for a wide range of construction projects.
It employs 40,000 people - 500 of which are based in the North East - and operates across the UK, the Middle East and Canada.
The group was named as the preferred bidder for the Liverpool project in July.
At the time, chief executive Richard Howson said: “I believe that being selected for this prestigious project reflect Carillion’s reputation for high standards of quality, health and safety and sustainability.
“We looking forward to working closely with Liverpool Football Club to create new world-class facilities at its famous Anfield Stadium.”
