"My career has been all about good fortune" says Arup Deputy Chairman Tristram Carfrae. From early years assisting mercurial genius Peter Rice to acting as engineer for man-of-the-moment Thomas Heatherwick’s Garden Bridge in London, he has worked with the greats of engineering and architecture. Now Carfrae, the designer of the stunning Beijing Olympic Aquatic Centre, is confirmed as one too, as the 2014 recipient of the Institution's Gold Medal.
