Atkins is a British multinational engineering, design, planning, architectural design, project management and consulting services company. It is a subsidiary of SNC-Lavalin and is headquartered in London.
The company was founded as WS Atkins & Partners by Sir William Atkins in 1938. It experienced rapid growth following the Second World War, performing specialist services in town planning, engineering sciences, architecture and project management. The firm was admitted to the London Stock Exchange in 1996, trading under the name WS Atkins plc for a time before rebranding as Atkins during 2002. While Atkins largely focused on the UK market during its formative years, it has grown into an international firm with a global presence, as well as expanded into a wide range of sectors, including aerospace and high speed railways.
By 2016, Atkins had become the UK's largest engineering consultancy, as well as the world's 11th largest global design firm. It employed approximately 18,000 staff based in 300 offices across 29 countries and had undertaken projects in over 150 countries. The firm's motto is "Plan, Design, Enable". During July 2017, Atkins was acquired by SNC-Lavalin in a £2.1 billion deal.
