A mechanical floor, mechanical penthouse, or mechanical level is a story of a high-rise building that is dedicated to mechanical and electronics equipment. "Mechanical" is the most commonly used term, but words such as utility, technical, service, and plant are also used. They are present in all tall buildings including the world's tallest skyscrapers with significant structural, mechanical and aesthetics concerns.
While most buildings have mechanical rooms, typically in the basement, tall buildings require dedicated floors throughout the structure for this purpose, for a variety of reasons discussed below. Because they use up valuable floor area (just like elevator shafts), engineers try to minimize the number of mechanical floors while allowing for sufficient redundancy in the services they provide. As a rule of thumb, skyscrapers require a mechanical floor for every 10 tenant floors (10%) although this percentage can vary widely (see examples below). In some buildings they are clustered in groups that divide the building into blocks, in others they are spread evenly through the structure, while in others still they are mostly concentrated at the top.
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. In some legislations they have been excluded from maximum floor area calculations, leading to significant increases in building sizes; this is the case in New York City. Sometimes buildings are designed with a mechanical floor located on the thirteenth floor, to avoid problems in renting the space due to superstitions about that number.

Famous quotes containing the words floor and/or mechanical:
“They seldom looked happy. They passed one another without a word in the elevator, like silent shades in hell, hell-bent on their next look from a handsome stranger. Their next rush from a popper. The next song that turned their bones to jelly and left them all on the dance floor with heads back, eyes nearly closed, in the ecstasy of saints receiving the stigmata.”
—Andrew Holleran (b. 1943)
“There is only one evil, to deny life
As Rome denied Etruria
And mechanical America Montezuma still.”
—D.H. (David Herbert)
