The tubular systems are fundamental to tall building design. Most buildings over 40-stories constructed since the 1960s now use a tube design derived from Khan's structural engineering principles, [2] [8] examples including the construction of the World Trade Center, Aon Center, Petronas Towers, Jin Mao Building, and most other supertall ...
A drawing the intended locations of plant items and service routes in such detail as to indicate the design intent. The main features of detailed design drawings should be as follows: Plan layouts to a scale of at least 1:100. Plant areas to a scale of at least 1:50 and accompanied by cross-sections.
Otis later designed a special elevator for the building. Peter Ellis, an English architect, installed the first elevators that could be described as paternoster elevators in Oriel Chambers in Liverpool in 1868. [14] The Equitable Life Building, completed in 1870 in New York City, is thought to be the first office building with passenger ...

Stiltz elevators run on freestanding, self-supporting rails, so they don’t need supporting walls or elevator shafts. However, the compact design means the Duo Classic model can’t accommodate ...
Hoist atop an elevator. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.
A paternoster in Prague Paternoster elevator in The Hague, when it was still in operation. A paternoster (/ ˌ p eɪ t ər ˈ n ɒ s t ər /, / ˌ p ɑː-/, or / ˌ p æ-/) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two people) that move slowly in a loop up and down inside a building without stopping.
Mechanical floors are generally counted in the building's floor numbering (this is required by some building codes) but are accessed only by service elevators. Some zoning regulations exclude mechanical floors from a building's maximum area calculation, permitting a significant increase in building sizes; this is the case in New York City. [1]
