Khaldoun Fahoum, a geotechnical engineer, soils and foundation expert and a vice president and U.A.E.-based Middle East regional manager for Langan Engineering, died on July 23 in Dubai, says the firm.

The cause of death was cancer, it says. Fahoum was 51 years old, says Langan.

He joined Langan in 2008 and was key to the firm’s involvement in several major projects, most notably Kingdom Tower and King Abdullah Financial District in Saudi Arabia.

A 20-year industry veteran, Fahoum also was Middle East chairman of the Deep Foundations Institute and named a trustee in March.

He had extensive experience in deep and raft foundations for high-rise buildings and offshore structures and analyses of liquefaction and leg penetration for large, jack-up rigs. He also had expertise in numerous soil improvement techniques, including dynamic compaction and vibrofloatations, says DFI.
