Our History


Construction of Place Ville Marie in 1961

Founded in 1964 by R. R. Nicolet, the firm now known as NCK Inc., took off after the completion of Phase 1 of the cruciform building of the Place Ville Marie Complex (1958–1962), a major project carried out in collaboration with architect I. M. Pei, who helped reorient the development of downtown Montréal. To this day, PVM remains the heart of downtown and the focal point of underground Montréal.

During this period, the firm carried out the project of Place Ville Marie other buildings, as well as the design of Place Bonaventure, Pyramids of the Olympic Village, Mirabel International Airport and Port Royal 33-storey skyscraper. Moreover, the latter retained the title of the highest residential tower in Québec until the construction of the Altitude in 2010, also carried out by the firm.

In the early ’70s, the firm was approached by the Canadian National Railway wanting to show the strength of Canadian industry by building the tallest building in the world. The CN Tower was completed in 1976 with the contribution of the firm’s comprehensive structural consulting engineering services. The tower has been chosen by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World and held the title of the tallest building in the world until 2005. This achievement, as well as collaboration with architect I. M. Pei in projects such as the Everson Museum of Art (New York, 1965) and the Herbert F. Johnson Museum (New York, 1973), has propelled the firm’s reputation on the international scene.

The firm was commissioned by the French government, under the recommendation of I. M. Pei, for the realization of the structure of the Grand Louvre Pyramid in Paris. While new projects were being carried out in Québec, the firm’s involvement was increasing in Europe, leading to the creation of an office in Zürich dedicated to the projects of the Midfield Terminal of Zürich Airport and Bern’s Fire station, Feuerwehrstützpunkt.
