Ironworkers at Ultium Cells LLC’s battery cell manufacturing facility marked a construction milestone with the final beam installation at what will soon be a 2.8-million-square-foot operation in Lordstown, Ohio. Ultium Cells, a joint venture between General Motors and LG Chem, will mass-produce Ultium battery cells at the facility. GM and LG Chem are investing $2.3 billion in the facility to support EV manufacturing in the US.

More than 500,000 hours have been devoted to development of the facility, which is slated for completion in 2022. This includes creation and installation of the USA-made steel structure. The building’s framework allows for an innovative open floor plan environment, with a main corridor spanning the width of the building interior and creating a natural connection point across the operation.

The plant will equal the size of 30 football fields and will have annual capacity of more than 30 gigawatt hours with room to expand.
