BE (Hons), MS(Calf), Hon FIEAust, CPEng, Hon DE(UWA), FTSE, FAICD, FAIM


Harold Clough is a highly respected and distinguished Australian industrialist, entrepreneur and philanthropist.

Dr Clough graduated in 1947 from the University of Western Australia with first class honours degree of Bachelor of Mechanical Engineering. In 1951 he was awarded the prestigious Fullbright Scholarship and attended the University of California in the US, where he gained a Master of Science in Industrial Engineering.

In 1954 he returned to Western Australia to join his father's building company, later becoming Chairman and Director of Clough Limited, the holding company for Clough Engineering Group.

One of Clough's earliest projects was the construction of the iconic Narrows Bridge in Perth, built in 1957.

The bridge dominates the Perth skyline, connecting the northern and southern suburbs, otherwise separated by the vast expanse of the Swan River.

Clough's reputation and capital growth exploded in the 1960s when Clough Engineering became a major construction force during the unprecedented development of the iron-ore industry in the Pilbara region of Western Australia. Clough was also a prominent contractor in the North West Shelf oil and gas development.

Dr Clough initiated the Clough Engineering Scholarship nearly 50 years ago which annually gives financial support to outstanding engineering students. There are now over 150 Clough Scholars who meet at the Clough Scholars Dinner at the University of Western Australia.

Clough Ltd, from the time of the Narrows Bridge in 1957, made a specialty of working in joint venture with the world major engineering companies. Clough did its first work overseas when it went to Indonesia in 1964 and until sold to Murray & Roberts, a South African company in 2007, did more work overseas than in Australia.
