Lavalin
Lavalin was a Canadian civil engineering and construction firm located in Montreal, Quebec. After a major expansion program in the 1980s that led to financial difficulties, in 1991 Lavalin merged with its long-time competitor, Surveyer, Nenniger & Chenevert Consulting Engineers (SNC), to become today's SNC-Lavalin, forming one of the ten largest engineering firms in the world.
