The story
Expedition Engineering was founded in 1999 by Professor Chris Wise (engineer for the Millennium Bridge, London) and Seán Walsh, both former employees at Arup.
On 2 October 2008, Expedition's ownership was restructured, passing to an Employee Benefit Trust called the Useful Simple Trust. The Useful Simple Trust also owns Thomas Matthews, a sustainable communication design practise; Think Up, a company specialising in engineering educational materials; Useful Simple Projects, a strategic sustainability consultant, and Useful Studio an architecture design practise.
The trustees of the Useful Simple Trust are:
