A division of The InterTech Group Inc. is expected to bring 350 jobs to a North Charleston plant that will be a supplier to aerospace manufacturers in the Southeast, it was announced today.

The first phase of the new $30- to $40-million factory is expected to open in the fall of 2012.

Hiring details were not immediately available, but about 20 percent of the hires are expected to be engineers and other highly skilled technical workers.

"It will not just be blue-collar jobs," said Anita Zucker, InterTech's chief executive officer.

The 25-acre factory site is on the Ingleside Plantation property, which is near U.S. Interstate 26 and Highway 78. It will be run by InterTech's TigHitco Inc. unit and is expected to provide aircraft components made from composite materials.

InterTech has not determined which parts will be made at the new factory.

Company officials down-played any connections between its investment and Boeing Co.'s newly opened 787 aircraft assembly plant at Charleston International Airport.

"They had no bearing on our decision to do business here," said Jonathan Zucker, InterTech president.

He and other company officials stressed that the new plant is aimed at serving numerous aerospace companies in the Southeast, including the local Boeing campus and the Gulfstream aircraft plant in Savannah.

The first phase calls for a 120,000-square-foot building, which later could grow to 300,000 square feet.

TigHitco already counts Boeing as one of its clients. It describes itself on its website "an industry leader in the design and fabrication of engineering components for aerospace and industrial applications." TigHitco's Aerostructures Division is based in Berlin, Conn.

Until today, the secretive deal had been code-named "Project Bird" by the S.C. Commerce Department.

Privately held InterTech is a global industrial conglomerate based in North Charleston and owned by the Zucker family.
