Peter Tom is to step down as chief executive of quarry giant Aggregate Industries and become the group’s part-time chairman. Mr Tom, 65, will be replaced by Bill Bolsover, currently the Bardon-based company’s chief operating officer. Both men take up their new posts on January 1. 
 
Part-time chairman Lord Fowler is to become a member of parent company Holcim’s governing body. The cement maker bought Aggregate for UK£1.8bn in January.  Mr Bolsover will become area manager at Holcim, in charge of operational excellence in aggregate, ready-mix and other downstream activities. 
 
A statement from Holcim said in his current role Mr Bolsover had "been instrumental in the smooth integration of Aggregate Industries into the Holcim Group."
