Our history

One October morning in 1945, two young engineers, Børge Johannes Rambøll and Johan Georg Hannemann, stood side by side on the roof of the Danish Technical University where they worked in the centre of Copenhagen.

“We stood there on the roof and talked about the company we wanted to establish,” recalled Børge Johannes Rambøll many years later. “What if we set up a little firm of our own?” 

It turned out that Rambøll and Hannemann were a perfect match; Rambøll, a visionary humanist with excellent leadership skills complemented Hannemann, a highly talented engineer with a flair for technical details. 

From the very beginning, they had a clear vision for how a responsible company should act and behave. They wished to ensure a long-term future for the company and the key to this was behaving decently and fairly – not just with clients but with each other.
