He is a Fellow of the Institution of Structural Engineers and of the Royal Academy of Engineering in London. He has been a board and committee member of the Norwegian Concrete Association, Oslo, Norway, for many years and was President from 1987 to 1989. He has also been a member of the International Federation for Structural Concrete (FIP, now fib) and served as President from 1992 to 1996. He has served on the committees of several international conferences on high-performance concrete and has published more than 50 papers.
In 1998, he received the Freyssinet Medal from FIP for outstanding contributions in the field of structural concrete. In 2005, he received the Albert Caquot Medal from the French Association of Civil Engineers (AFGC) in recognition of his contributions to civil engineering construction.
His research interests include offshore concrete structures and bridges, as well as the education, research, and work of voluntary professional organizations.
