History

Planning for the complex began in the late-1970s following the creation of Petro-Canada. Petro-Canada came to an agreement with the West German firm ARCI Inc. to jointly develop an ARCI-owned site in Calgary to host the Crown Corporation's new headquarters. ARCI Inc served as an investment corporation, which had purchased the site several years early, and continues to be owned by the German

. In May 1980, a $200-million design was proposed with an all-glass, three-tower design including a 25-storey tower to be completed in 1982 and a larger 50-storey tower completed later in 1983. The Calgary Planning Commission rejected the proposal in Fall 1980 as the site was not large enough for the density three towers would provide, and the all-glass design was not desirable for the city. Subsequently, Petro-Canada purchased the

Construction on the complex began on April 2, 1982. During construction, local controversy arose when no Canadian bids were received to supply the site with exterior granite cladding, which resulted in the use of $500,000 of Finnish granite, which was cut and polished in Italy and shipped to the Calgary site for installation. Another local controversy was the installation of
