Alfred McAlpine
Alfred McAlpine plc was a British construction firm headquartered in Hooton, Cheshire. It was a major road builder, and constructed over 10% of Britain's motorways, including the M6 Toll (as part of the CAMBBA consortium). It was listed on the London Stock Exchange until it was acquired by Carillion in 2008.
History
Alfred McAlpine was one of the sons of 'Concrete' Bob McAlpine and he ran the operations of Sir Robert McAlpine in the north west of England. In 1935, following the death of Sir Robert and his eldest son, Alfred ran the north west independently, although the legal separation was not completed until 1940, when Sir Alfred McAlpine & Son was formed. Under a non-compete agreement with its former parent company, Sir Alfred McAlpine confined itself to civil engineering and to the north west of England.
After the death of its founder, his son Jimmie McAlpine became chairman. The company floated on the London Stock Exchange in 1958 under the name Marchwiel Holdings, only changing its public name to Alfred McAlpine PLC in 1985.
This followed the decision in 1983 to end the non-compete agreement with Robert McAlpine allowing the firm to expand geographically.
