Mr Calton will direct KBR’s project management and controls (PMOC) department as well as the company’s engineering, procurement, construction and services (EPCS) department. Mr Calton will assume the duties formally held by David Zimmerman, who was named president of KBR Services last fall. Mr Zimmerman will now focus exclusively in the role of president of KBR Services.

The company said that Mr Calton’s promotion is part of KBR’s continued effort to maximize its business structure, while positioning the company for future growth.

William Utt, chairman, president and CEO of KBR, said: Dennis brings a wealth of experience to his position. In his over 30-year tenure with KBR, he has served in key project management and engineering roles. I am confident Dennis’s leadership will provide added value to KBR’s work in positioning itself as a market leader, focused on future growth and success.
