Texas Instruments has plans to build as many as four semiconductor chip fabrication plants in Sherman, Texas, at a cost totaling nearly $30 billion. Work on the first plant broke ground last month.

The plans for the first plant, known as a “fab,” include construction of a 1.04-million-sq-ft manufacturing building, plus support buildings and ancillary facilities at a total expected cost of $6.5 billion in the city about an hour north of Dallas, Sherman city records show. Austin Commercial is the general contractor for the project, according to Dodge Global Network data. Neither Texas Instruments nor Austin Commercial immediately responded to calls for comment, though Austin Commercial hosted a virtual supplier fair for Texas Instruments’ Sherman manufacturing facilities in March.
