Sources estimate the 2.7m sq ft factory project, which has been designed by Italian architect Pininfarina, could be worth approaching £300m.
Richard McDonell, Britishvolt Project Director, said: “Today is a historic day as it marks the start of construction on the UK’s premier Gigaplant, Britishvolt – a landmark event for UK manufacturing and the automotive industry on the road to zero.
“It is a pleasure to see our tier one construction partner ISG, and its world-class workforce, commence preliminary works on site ahead of the main construction programme, which we anticipate will start in late autumn/early winter.
“This initial phase will see the site cleared and preparatory work carried out for the services and infrastructure that will support construction activity.”
Main construction work will see more than 2,500 people involved in the project.
Peter Millett, High Tech Managing Director for ISG’s Engineering Services business said: “The positive momentum, passion and sense of genuine excitement that underpins this nationally important project is driving the entire team forward at pace, and this significant construction milestone demonstrates our collective commitment to UK manufacturing and to supporting communities across Northumberland.
“This is the starting point for the transformation of a disused site in Cambois with a legacy in the industrial past, that from today will become a beacon for innovation and advanced manufacturing right here in the North East.”
