Commonwealth Construction Limited


Commonwealth Construction Limited, a full-service industrial Canadian construction firm, began in 1907. Presently owned by CH2M HILL of Denver, Colorado, the company maintains branches across the country and has been involved in a number of significant Manitoba building projects throughout its long history. The company was particularly active during the post-war years. Amongst the many commercial, institutional and infrastructure projects that Commonwealth Construction has been responsible for, are the Winnipeg International Airport’s 1964 modernist terminal building, now demolished (2000 Wellington Avenue; designed by Green Blankstein Russell and Associates). Excavation for this project began in spring of 1960, with construction commencing that August. Notably, the firm had previously worked on the north-west and south-east runways of the previous Stevenson airport. Other works include the S.S. Kresge Company Limited (368-374 Portage Avenue, 1954) Winnipeg location, the Polo Pork Simpson-Sears store (1485 Portage Avenue, 1959). For many years the company worked out of offices at the Royal Bank Building, Winnipeg. It also at one point operated a large diesel asphalt plant, located at Rosenfeld which was said to be the largest of its kind in Canada.
