AI UK, which became part of the Holcim Group in 2005, grew to a £1.5bn organisation under Bolsover’s leadership, which involved a number of acquisitions. He will become non-executive chairman of the AI Europe board of directors and will remain a member of the AI US board.

Bolsover will be replaced by Alain Bourguignon, who is currently CEO of Holcim Spain and has experience of both the aggregate and ready-mix concrete business.

Benoit Koch, chairman of AI UK and a member of the Holcim Group executive committee, said: “We are hugely grateful to have had Bill at the helm of our UK interests for the last four years. He is a dynamic and charismatic leader whose vision, strategic awareness and energy have delivered a strong performance despite difficult economic conditions and intense competition.”
