Mott MacDonald’s engineering and technical knowledge was instrumental in building NHS Nightingale hospitals in London, Cardiff, Manchester and Glasgow. Led by executive chair Mike Haigh, 60, the employee-owned consultancy called on its experience of rebuilding roads and bridges in Cumbria after storms in 2015.

It also developed the masterplans for the ongoing $13bn expansion of JFK airport in New York and Jakarta’s first metro system, which opened last year.
