The Union Bank Building is the oldest skyscraper in Canada and is located in the Exchange District of Winnipeg, Manitoba. Construction began in 1903 and it opened in November 1904. The 10-storey building was Winnipeg's first skyscraper south of City Hall, and was the tallest building in Winnipeg at the time of its construction. Initially built for Union Bank, now houses the Hospitality programs of Red River College.〔〔 It was designated as a National Historic Site of Canada in 1996. ==Construction== The Union Bank Tower is an example of the Chicago Style.〔 Using technology that was cutting edge for its time, the building was constructed with a network of steel and reinforced concrete that provided support for the brick and terracotta walls. The previously common building support system was that of wooden beams and posts or masonry. The tower's steel framing increased the overall rigidity and fire resistance of the structure compared to its predecessors.〔 At the time of its original construction, the building rose to above grade, running on Main Street, along William Avenue, at the rear, and on its south side.〔 The design of the building is based on a classical column. The bottom two storeys form the base and are highly ornamented. The middle storeys form the body of the column and are less ornamented, and the upper level have similar embellishment to the ground floor. Designed by two of Canada’s top architects, Frank Darling and John Andrew Pearson, initial construction of the building cost $420,000 and it was built by two New York City construction firms: ''George A. Fuller Company'' and ''Thompson and Starret and Company''.〔 The frame of riveted interlocking girders was manufactured by Dominion Bridge of Montreal, and the ochre brick came from the Lac du Bonnet brickworks.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Union Bank Building」の詳細全文を読む スポンサード リンク
