Monadelphous Group has appointed Dietmar Voss as a non-executive director.
The appointment follows the January resignation of non-executive director Irwin Tollman, who had been a member of the Monadelphous board since 1992.
Mr Voss recently retired after 40 years in the oil and gas and mining industries, and has previously served at BHP Billiton, Bechtel and Hatch.
