Severfield is set to start on site with steelwork next month at Sir Robert McAlpine’s flagship £4bn Agratas gigafactory site in Somerset.

The order for the full structural steel package for the first phase of the mega-job has been signed with production now underway at Severfield’s Dalton site.

The firm will be supplying and fabricating structural steel, supplying decking and applying intumescent paint coatings.

Sir Robert McAlpine has been overseeing site preparation work for Tata-owned Agratas since last summer but the job has faced construction delays as plans for the site were revised.

Agratas has confirmed that the size of the first 2.6m sq ft building is being reduced by “about 100 metres.” and the “timeline is shifting slightly” with the first phase now due to be completed in 2027 rather than 2026.
