A double-deck elevator or double-deck lift is an elevator where one cab is stacked on top of another. This allows passengers on two consecutive floors to be able to use the elevator simultaneously, significantly increasing the passenger capacity of an elevator shaft. Such a scheme can improve efficiency in buildings where the volume of traffic would normally have a single-deck elevator stopping at every floor. For example, a passenger may board the lower deck (which serves only odd-numbered floors) at basement level while another passenger may board the upper deck (which serves even-numbered floors) on the ground floor—the cab serving even floors is on top of the cab serving odd floors.

Double-deck elevators occupy less building core space than traditional single-deck elevators do for the same level of traffic. In skyscrapers, this allows for much more efficient use of space as the floor area required by elevators is significant.

The other main technique for reducing the floor area occupied by elevators is shared-shaft elevators where multiple elevators use different sections of the same shaft to serve different floors with skylobbies separating the sections. The Thyssenkrupp TWIN elevator places 2 independent elevator cabs in 1 shaft and the Thyssenkrupp MULTI system places several elevator cabs in one shaft—each cab is equipped with its own, independent linear motor and can move vertically but also horizontally from one shaft to another.

Double-deck goods/passenger elevators

Not all double-deck elevators are used to transport passengers simultaneously in both decks. The second deck in a double-deck car may be used for the transportation of goods, typically outside of peak traffic periods. This technique has the advantages of preventing damage to interior fixtures due to impact from trolleys and not requiring a shaft dedicated to a goods-only elevator car. During peak periods, the elevator is used in passenger-only mode.

As of 2011, no triple-deck elevators have been built, although such a design had been considered for the 163-floor Burj Khalifa before the final design was scaled back to double-deck. [3]

The CN Tower is a 553.3 m-high (1,815.3 ft) concrete communications and observation tower in Toronto, Ontario, Canada. Completed in 1976, it is located in downtown Toronto, built on the former Railway Lands. Its name "CN" referred to Canadian National, the railway company that built the tower. Following the railway's decision to divest non-core freight railway assets prior to the company's privatization in 1995, it transferred the tower to the Canada Lands Company, a federal Crown corporation responsible for the government's real estate portfolio.

A skyscraper is a tall continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.

Elevator surfing, also known as lift surfing, is an activity involving riding on top of elevators, rather than inside them. More experienced surfers may attempt riskier maneuvers such as jumping between moving elevators, or riding the elevator's counterweight. Elevator surfing is typically considered a form of urban exploration, more aligned with investigative experiences like rooftopping and tunnel hacking rather than adrenaline-inducing urban sports like train surfing. While elevator surfing was most prominent as a subculture in the United States and United Kingdom in the 1990s, it made a comeback in the late 2010s, with partakers often posting footage of their adventures on YouTube and similar platforms.

A multistorey car park or parking garage, also called a multistorey, parking building, parking structure, parkade, parking ramp, parking deck, or indoor parking, is a building designed for car, motorcycle, and bicycle parking in which parking takes place on more than one floor or level. The first known multistorey facility was built in London in 1901, and the first underground parking was built in Barcelona in 1904. The term multistorey is almost never used in the US, because almost all parking structures have multiple parking levels. Parking structures may be heated if they are enclosed.

<span class="mw-page-title-main">Skyscraper design and construction</span>

The design and construction of skyscrapers involves creating safe, habitable spaces in very high buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among the most complex encountered given the balances required between economics, engineering, and construction management.

The Roads and Transport Authority (RTA) was formed by the decree number 17 for the year 2005.
