Alfred McAlpine
British construction company
Alfred McAlpine plc was a British construction firm headquartered in Hooton, Cheshire. It was listed on the London Stock Exchange until it was acquired by Carillion in 2008.
The origins of Alfred McAlpine are strongly associated with the businessman Alfred McAlpine, a son of 'Concrete' Bob McAlpine, and the north western operations of Sir Robert McAlpine. These operations became legally distinct in 1940; 18 year later, the company was floated on the London Stock Exchange under the name Marchwiel Holdings. By this point, Jimmie McAlpine was the chairman of the company, a position he would hold until 1985. Prior to 1983, the company's operations were constrained by a non-compete agreement with Sir Robert McAlpine; while the geographical restriction was removed, some terms of agreement remained in effect between the two companies.
Throughout the second half of the twentieth century, Alfred McAlpine was a major road builder, being responsible for the construction of over 10% of Britain's motorways, including the M6 Toll (as part of the CAMBBA consortium). During the 1980s, it expanded its presence in the home building sector; by the late 1990s, McAlpine was building over 4,000 houses per year. However, the company opted to sell its homebuilding operations to rival company George Wimpey in August 2001. It also owned and operated Penrhyn Quarry, the country's largest slate works; a major accounting scandal at the company's slate subsidiary occurred during the mid-2000s.
This brief starts where responsible research should: with the source description of “Alfred McAlpine” as british construction company. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as british construction company. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Jun 14, 2026. The linked authority identifier is Q2576816. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2008, 1940, 1985 and 1983.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
