Introduction to Ramps
Unlock Audio Lesson
Welcome, everyone! Today we will be discussing the design guidelines for ramps according to the NBC 2016. Can anyone share why ramps are essential in our infrastructure?
They help people who use wheelchairs and those who may have difficulty with stairs.
Exactly! Ramps provide an important accessibility solution. Let's talk about the required **slope** of these ramps. What do you think is the maximum slope allowed?
Is it 1:12?
Correct! A maximum slope of 1:12 means for every 12 units you move horizontally, you can rise 1 unit vertically. This slope makes it easier for users. Let's remember this with the mnemonic **'1 for every 12'** — simple and effective!
Width of Ramps

Now, let's move to the **width** of ramps. Do you know the minimum clear width that is required?
I think it's 900 mm?
Not quite, but close! The minimum width is **1200 mm**. This width ensures that a wheelchair can pass safely. Let's use the acronym **'WIDE RAMP'** where 'W' stands for 'Width' and 'I' for 'Inclusive.'
That’s helpful! It makes it easy to remember why width matters!
Ramp Safety Features
Unlock Audio Lesson
Ramps must also include **edge protection**. Why do you think this is necessary?
To prevent users from falling off?
Exactly! Thus, a minimum height of **75 mm** for raised curbs is mandated. To remember this, think about the rhyme: **'Seventy-five will keep you alive'** on the ramp!
Conclusion of Ramp Design Standards
Unlock Audio Lesson
To summarize, we discussed the key elements of ramp design: a maximum slope of 1:12, a minimum clear width of 1200 mm, and edge protection of at least 75 mm height. Can anyone repeat these points back to me?
1:12 slope, 1200 mm width, and 75 mm edge protection!
Great job! Remember these as we move forward in our studies of accessibility!

Quick Overview
Standard
The section elaborates on ramp design standards, including slope, width, and edge protection, to facilitate universal accessibility for individuals with mobility challenges in compliance with NBC 2016.
Detailed
Ramps in Accessibility Design
In accordance with the National Building Code of India 2016 (NBC 2016), ramps are essential architectural elements that promote accessibility for all individuals, particularly those with disabilities and mobility constraints. The guidelines specify that:
- Slope: Ramps should not exceed a slope of 1:12, ensuring a gradual incline for users.
- Width: A minimum clear width of 1200 mm is mandated to allow movement and safe passage for wheelchair users.
- Edge Protection: Ramps must feature raised curbs with a minimum height of 75 mm to prevent users from rolling off the sides.
These design elements are crucial for integrating ramps into urban spaces, ensuring dignity and independence for all persons, as detailed in Part 3 of the NBC 2016.

Ramp Slope Requirements

- Slope: Should not be steeper than 1:12.
Detailed Explanation
The slope of a ramp is very important for accessibility. A ratio of 1:12 means that for every inch of vertical rise, there must be at least 12 inches (or 1 foot) of ramp run. This gentle slope allows individuals, particularly those in wheelchairs or with mobility issues, to ascend or descend safely without excessive strain.
Examples & Analogies
Imagine you're pushing a stroller up a hill. If the hill is too steep, it becomes hard to push. But if the slope is gradual, the task is much easier. The same principle applies to ramps for accessibility.
Ramp Width Requirements

- Width: Minimum 1200 mm clear width.
Detailed Explanation
The width of a ramp must be at least 1200 mm (about 4 feet) to ensure that it can accommodate wheelchairs and individuals using mobility aids alongside caregivers or companions. This width prevents congestion and allows for safe, unobstructed travel.
Examples & Analogies
Think of a crowded hallway. If it's narrow, people might bump into each other and struggle to pass through. However, if the hallway is wide enough, everyone can move comfortably, just like how a ramp should be designed.
Edge Protection

- Edge Protection: Raised curbs of minimum 75 mm height.
Detailed Explanation
Edge protection is crucial for ramps, as it prevents individuals from accidentally rolling off the sides. A minimum raised curb of 75 mm acts as a barrier to keep users safely on the ramp, particularly in instances where they might lose balance or control.
Examples & Analogies
Consider riding your bike along a path with a guardrail. The guardrail stops you from going off the edge, making your ride safer. Similarly, edge protection on ramps serves to enhance user safety by preventing falls.
Definitions & Key Concepts
