CALGARY, ALTA. - A protective wrap that protects construction crews and materials from winter is giving Calgary residents a window into the past.
Because the Historic City Hall will be covered until 2020, when the project will be completed, the city is using images that replicate the original appearance of City Hall as part of the wrap.
"Given the Canada 150 celebrations that took place on Olympic Plaza and the Municipal Plaza this year, the imagery is also a fitting tribute to Canada's historic anniversary," reads a release from the city.
The enclosure is also a key part of avoiding high costs due to weather delays by allowing workers to work year-round. In addition, the covering allows no water penetration which is vital in helping to protect the aging sandstone and exposed building components from the weather, a release reads. This also helps mortar cure properly during the winter as the temperature inside the wrap is a minimum of 10 C, rising to about 20 C in the upper floors.
The whole enclosure cost roughly $165,000.
The building was built between 1907 and 1911 and its iconic clock tower has been one of the city's most familiar landmarks for over a century. At 106 years old, it's the only surviving city hall of its period in Western Canada and is a national, provincial and municipal heritage resource, the release continues.
But the years have taken their toll on the building and its sandstone structure shows signs of deterioration. Calgary City Council approved a $34.1-million investment to support its renewal in 2014.
