2.2.7 Width & Slope of Ramp

 The clear width leading to the basement must be 4 meters, with a slope of no more than
1:10 to ensure ease of passage.

 Separate ramps for entry and exit are necessary, each having a clear width of 4 meters

to provide for smooth traffic movement.
Thesis Report V-SPARC VIT
 The ramps should have a gradual slope with a maximum gradient of 1:12, and after

every 9 meters of travel, there should be a landing place measuring 1800mm by
1800mm to allow for resting or manoeuvring.

 To properly accommodate humans, the ramp width must be 1800mm or wider.

 To provide users with support and guidance, handrails must be provided on both sides
of the ramps at two different heights: 760mm and 900mm.

 To improve safety and accessibility, the handrails should extend 300mm beyond the

ramp's top and bottom.
 Warning tiles should be placed 300mm before the ramp edges to notify people to the

presence of the ramps and raise awareness about potential hazards.

2.2.8 Pressurization of Staircases (Protected Escape Routes)

 Pressurization is a technique used, particularly in high-rise buildings, to
safeguard escape routes from smoke infiltration.

 Pressurization prevents smoke or hazardous gases from entering the escape

routes by pumping air into the lobbies, hallways, and stairs to boost their pressure
slightly over that of the building's surrounding areas.

 Pressurization of stairwells is required for high-rise structures, mixed-use

buildings, and multiplexes with more than 500 square meters of covered space.
