Steepness of stairs – rise and going. Any rise between 150 and 220 used with any going between 220 and 300 Maximum rise 220 and minimum going 220 remembering that the maximum pitch of private stairs is 42°. The normal relationship between dimensions of the rise and going is that twice the rise plus the going (2R + G) should be between 550 ...
d = run Δh = rise l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent.
In South Africa 1:12 is the maximum slope unless the difference in level is less than 400mm, in which case it is 1:10. [SANS 10400-S SS2(a)]. In Australia, the National Construction Code requires a wheelchair ramp to have a maximum incline of 1 in 8. This means that for every 8 metres (26 ft 3 in) travelled horizontally, the ramp rises 1 metre ...
Good lighting is important in a staircase so users see where they are going and to prevent falls. [6] There is often a window on the wall to let in daylight.In many cases, indoor stairs are placed far inside the building structure, and it is often not easy to get access to a wall on the outside where it would be natural to have a regular window for letting daylight in.
The visibility and accessibility of the escalator to traffic is relevant. Designers need to account for the projected traffic volumes. For example, a single-width escalator traveling at about 0.5 metres per second (1 + 1 ⁄ 2 ft/s) can move about 2000 people per hour, assuming that passengers ride single file. The carrying capacity of an ...
A dog-leg staircase A quarter-landing, on a dog-leg staircase, is made into an architectural feature, by the use of arches, vaulting and stained glass. A dog-leg is a configuration of stairs between two floors of a building, often a domestic building, in which a flight of stairs ascends to a quarter-landing before turning at a right angle and continuing upwards.

In India FAR and FSI are both used. FAR regulations vary from city to city and generally it is from 1.3 to 3.25. In Mumbai 1.33 is the norm but higher FSI is allowed along the Metro rail line and slum areas like Dharavi. In Bangalore, 40 feet streets allow only an FAR of 1.75 but 100 feet streets allow 3.25 FAR. [citation needed]
New building regulations that came in force in 2020, limited the height of buildings on cities depending on population in China.Cities with less than 3 million population cannot have structures rising above 250 m (820 ft); cities with populations greater than 3 million can have buildings up to a height of 500 m (1,600 ft).
