The story

Founded by Arthur Surveyer in 1911.1

SNC (1911–1991)

In 1911, Arthur Surveyer established a consulting engineering office, Arthur Surveyer & Cie., in Montréal after completing studies in Belgium and at Polytechnique Montréal and working for several years with public works. Against the backdrop of the transformative advances in electrification. Surveyer worked on hydropower projects with his partner, Augustin Frigon (1888–1952), an engineer, professor, and Director at Polytechnique Montréal where Surveyer had earned his degree. In 1912, they worked on a power distribution network for the city of Grand-Mère on Saint-Maurice River. The project that increased the company's profile was the Saint-Maurice River hydroelectric power station, which they designed and supervised. The company specialized in hydraulics, managing hydropower projects and flood control, and soon branched out into the industrial sector, particularly in pulp and paper, and mining and metallurgy.

Surveyer formed a first 10-year partnership with Emil Nenniger and Georges Chênevert in 1937. A second partnership agreement was signed in 1946, and the firm's name was changed to Surveyer, Nenniger and Chênevert. The name would eventually be abbreviated to SNC.

In 1967 Camille A. Dagenais, became president and CEO of SNC Group, a position he held until 1975. When Dagenais was inducted into the Order of Canada, he was honoured for his accomplishments at SNC—specifically for large-scale hydro development projects in Canada and internationally, for example, in India and Greece. One of the most important projects was the work he oversaw on the recently nationalized Hydro-Québec's Manic-5 project (1959–1970) on the Manicouagan River, north of Baie-Comeau. It was built for hydroelectric power production and supplies water to the Manic-5s power houses. The firm's first international contract was awarded in 1963, to design and build the 780 MW Idukki power station in Kerala State, India.

Lavalin (1936–1991)

SNC's main rival in Canada was Lalonde, Valois International Limited, a company that was established in 1936 by engineers Jean-Paul Lalonde and Romeo Valois. Bernard Lamarre, who would later become director and CEO in 1962 and lead Lavalin for 29 years, had married Louise Lalonde, Jean-Paul Lalonde's daughter in 1952, and began working at Lalonde, Valois International Limited. In 1972, the company changed its name to Lavalin—combining syllables from the original company name. In the 1970s, Lavalin designed and built the fabric roof for Montreal's Olympic Stadium and built the James Bay Project, in a partnership with the United-States-based Bechtel.

According to a 1986 Maclean's article by Anthony Wilson-Smith, Lavalin was Canada's "largest engineering firm, with $625 million in operating revenues in 1985 and 5,700 employees. SNC was the second largest". Wilson-Smith also said that they were "among the largest engineering firms in the world". Lavalin branched out in other industries, such as cable television—Canada's The Weather Network and MétéoMédia were founded by Lavalin in 1988. Lavalin's shares were sold to Pelmorex in 1993. By 1990 Lavalin Inc included over 70 companies worth CA$1.2 billion. It was forced to sell to its rival SNC in 1991.

SNC-Lavalin (1991–2023)

Bernard Lamarre remained with the newly formed company, SNC-Lavalin until 1999. He oversaw major projects including the TransCanada highway in Montreal, the Louis-Hippolyte-Lafontaine Bridge-Tunnel, the Olympic Stadium in Montréal, and Alcan in the Ville de La Baie. He also oversaw projects in Benin and in Algeria.

Bernard Lamarre's younger brother, Jacques Lamarre, a civil engineer, became SNC-Lavalin's CEO in 1996 and left his post in 2009.

Acquisitions and partnerships

According to Ingram, SNC-Lavalin partnered with Bombardier in the 1990s to build transportation projects in Malaysia and Turkey. SNC-Lavalin acquired a 27% share in Ontario's Highway 407 toll road for $175 million. In 2011, SNC-Lavalin sold part of its share of Highway 407, at a significant profit.

In June 2011, SNC-Lavalin purchased the commercial reactor division of Atomic Energy of Canada Limited (AECL) from the Government of Canada for CA$15 million. SNC-Lavalin established a subsidiary company named Candu Energy to market the design and supply of CANDU reactors.

On June 23, 2014, SNC-Lavalin acquired Irish engineering and construction business Kentz for approximately CA$2.1 billion (US$1.95 billion).

In 2017, SNC-Lavalin acquired its UK rival Atkins—a British design, engineering and project management consulting firm, for approximately CA$3.36 billion with $1.9-billion investment from the Caisse de dépôt et placement du Québec.

In late 2018, SNC-Lavalin agreed to form a joint venture with the Swedish-Swiss industrial giant ABB for the delivery of turnkey electrical substation projects. This new company, named Linxon, undertakes project design, engineering, procurement, and construction activities for a range of clients in the transport, utilities, and renewable electricity generation and transmission sectors.

In 2021 the company's oil & gas business, including the former Atkins and Kentz oil and gas businesses, was sold to Dubai-based Kentech Corporate Holdings. After the transaction was completed Kentech changed its name to Kent plc.

AtkinsRéalis (2023–present)

On September 13, 2023, SNC-Lavalin announced it was rebranding to become AtkinsRéalis. President and CEO Ian Edwards said the new name combined the Atkins legacy brand and 'Réalis, inspired by the city of Montréal and the company's French-Canadian roots. The new name also evoked the word 'realise', as in 'make happen'. The new name was used immediately on all communications materials and the Toronto Stock Exchange (new ticker symbol TSX: ATRL). The legal name switch received shareholder approval at the company's annual general meeting in 2024.

SNC-Lavalin sold the Scandinavian businesses of Atkins to French engineering firm SYSTRA for $102 million in 2023.
