Chantiers looks at eight major construction projects which Quebec undertook in the 1960s and 1970s, from initial idea and concept, to production, and impact on society. These projects had a number of things in common: their size, scope and technical and technological challenges, the ideological debate they fostered, the domino effect of subsequent projects they engendered... and other mega-construction issues which Quebec had to face for the first time in its history.
