Inco Superstack vs Arraya Tower

Informations

The Inco Superstack in Sudbury, Ontario, with a height of 381 metres (1,250 ft), is the tallest chimney in Canada and the Western hemisphere, and the 2nd tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It's also the second tallest freestanding structure of any kind in Canada, behind the CN Tower but forward of First Canadian Place. It's the 40th tallest freestanding structure in the world. The Superstack is situated on top of the biggest nickel smelting operation in the world at Vale's Copper Cliff processing centre in the city of Greater Sudbury.

In 2018, Vale declared that the stack will be decommissioned and dismantled beginning in 2020. On July 28, 2020, Vale declared that the stack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in case of a malfunction in the new system, after which the dismantling of this Superstack will begin. In addition to further reducing sulfur dioxide emissions by 85 percent, the decommissioning of the pile is expected to cut the complex's natural gas consumption in half.

The Arraya Tower is a skyscraper completed in 2009 in Kuwait City, Kuwait.

The tower serves as a grade-A office construction. With sixty storeys, and 300 metres high (using a 45-metre spire), the building was the tallest tower in Kuwait until the construction of Al Hamra Tower in 2011. On January 19, 2010, The Council on Tall Buildings and Urban Habitat (CTBUH) announced that Arraya Tower was the 4th-tallest building completed in 2009. Curtis W. Fentress, FAIA, RIBA, of Fentress Architects, was the primary architect of the building, and Ahmadiah Construction was the primary contractor. The tower complements the Present 130-metre-high Arraya Tower housing offices and the Courtyard by Marriott hotel, as well as the upscale Arraya Shopping Mall and the Arraya Ballroom. Building on the tower began in February 2005, with occupation scheduled for February 2009. As of August 22, 2008, the tower was topped out and the superstructure was complete. Exterior cladding, consisting of white marble, green glass and steel rods, was largely complete. Interior works were well underway and wrapped up in early 2009 in time for the tower's opening.
