Locally based Barnhart Balfour Beatty has been renamed Balfour Beatty Construction, marking the final step in a transition following the 2008 acquisition of the former Barnhart Inc. by Dallas-based Balfour Beatty Construction.

A Sept. 27 company statement said the San Diego office has been designated as the company’s Southwest regional headquarters. The office will be led by Eric Stenman, most recently president of Barnhart Balfour Beatty, who is now the company’s Southwest regional chief executive officer.

“Our goal is to position ourselves for growth beyond what we could do as Barnhart alone,” Stenman said in the statement. “Fully embracing our Balfour Beatty Construction identity gives us the ability to extend our own geographic reach, while also leveraging the national resources, subject matter experts, and financial depth of the larger company.”

The local Balfour division is in the process of moving into new offices at 10620 Treena St. The company will maintain all current local satellite offices in Oxnard, Palm Desert, Riverside and Tustin; all 310 staff members will continue to report to those offices.

The former Barnhart Balfour Beatty is among the nation’s largest builders of educational facilities. The San Diego division and its parent firm recently won a $221 million contract to build the first phase of a county-run women’s detention facility in Santee, which will eventually replace the existing Las Colinas Detention Facility.
