Ramp Requirements
Unlock Audio Lesson
Let's start with ramps. What do we know about the minimum width and maximum slope for ramps according to the design checklists?
I remember the ramp must be at least 1200 mm wide and the slope cannot exceed 1:12.
Can you explain why the slope is limited to 1:12?
Good question! A slope of 1:12 ensures that ramps are manageable for all users, especially those using wheelchairs or other mobility aids. Can anyone remember a mnemonic that might help us recall this?
How about 'One foot up for every twelve feet out'?
Exactly! That’s a great way to keep the slope in mind. Let’s summarize: what are the ramp width and slope requirements?
Ramp width: minimum 1200 mm, and slope: not steeper than 1:12.
Door and Elevator Specifications
Unlock Audio Lesson
Moving on to doors, what is the minimum width for doors as per the NBC guidelines?
The minimum width is 900 mm.
What about elevators? Can anyone recall their minimum size?
Elevator cabins should be at least 1100 mm x 1400 mm!
Great! And for a stretcher lift, what size do we need?
2000 mm x 1500 mm!
Perfect! This helps us ensure accessibility for all users. To wrap up, what’s our key takeaway about door and elevator sizing?
Doors must be 900 mm wide, and elevators at least 1100 mm x 1400 mm.
Accessible Parking and Toilet Requirements
Unlock Audio Lesson
Next, let’s discuss accessible parking. How wide and long should these designated spaces be?
They should be at least 3600 mm wide and 5000 mm long.
And what is the required distance from the building entrance?
Great recall! Accessible parking should be within 30 meters of the building entrance. Now, turning to toilets, what are their minimum dimensions?
2200 mm by 1500 mm!
Exactly! Accessible parking and toilet design must be a priority for inclusivity. What do we summarize about parking and toilet requirements?
Accessible parking is 3600 mm wide, 5000 mm long, and within 30 meters of the entrance; toilets must be 2200 mm x 1500 mm.
Introduction & Overview

Quick Overview
Standard
The design checklists provided in this section encompass essential standards for accessibility features in buildings, including specifications for ramps, doors, elevators, parking spaces, and more, to ensure compliance with the NBC Part 3 guidelines.
Detailed
Design Checklists (As per NBC Part 3)
This section presents a comprehensive checklist for various building components as specified by the National Building Code of India (NBC) Part 3. These checklists are critical for ensuring that buildings are accessible to all individuals, particularly persons with disabilities (PwDs). The checklist includes specific standards, such as width and slope for ramps, door dimensions, elevator sizes, and accessible parking specifications. Each component's checklist ensures adherence to guidelines meant to promote inclusivity, dignity, and safety in the built environment, in alignment with legal mandates and best practices. This emphasizes the importance of designing spaces that are not only functional but also equitable for all users.

Ramp Width Min. 1200 mm
Ramp Slope Max. 1:12
Detailed Explanation
This chunk specifies the requirements for ramps in buildings. The width of a ramp must be at least 1200 millimeters. This ensures enough space for wheelchair users to navigate comfortably. The slope of the ramp should not exceed a ratio of 1:12, meaning for every 12 units of horizontal distance, there can be a 1 unit rise. This gentle slope is crucial for preventing strain and ensuring safety when using ramps.
Examples & Analogies
Imagine pushing a heavy shopping cart up a steep hill. It's much easier to push it up a gradual slope rather than a steep incline. Similarly, a ramp that is too steep can be difficult or even dangerous for someone using a wheelchair.
Door Specifications

Door Width Min. 900 mm
Detailed Explanation
The minimum width for doors is set at 900 millimeters. This is to ensure accessibility for individuals using mobility aids, such as wheelchairs or walkers, allowing them to enter and exit without difficulty. Wider doors also accommodate various users, including those with larger equipment.
Examples & Analogies
Think of a door as the entryway to a room. Just like having a wide entrance to a store allows more people to enter at once, wide doors in buildings provide the same ease, making it more user-friendly for everyone.
Elevator Specifications

Elevator Cabin Size 1100 mm x 1400 mm (min), 2000 mm x 1500 mm (stretcher)
Detailed Explanation
Elevators are crucial in multi-story buildings for accessibility. The minimum cabin size is specified as 1100 mm by 1400 mm to fit a standard wheelchair comfortably. For stretcher lifts, which are used for transporting patients, the size must be 2000 mm by 1500 mm. This ensures that individuals in stretchers can also use the elevator without difficulty.
Examples & Analogies
Consider an elevator as a small room moving up and down in a building. Just like a bigger room can accommodate more people comfortably, larger elevator cabins support safe transportation for those with special needs or medical conditions, like patients in stretchers.
Accessible Parking Specifications

Accessible Parking 3600 mm x 5000 mm
Detailed Explanation
The dimensions for accessible parking spaces are outlined to be 3600 mm wide and 5000 mm long. This ample space is necessary to allow individuals with disabilities to safely exit and enter their vehicles, particularly those who may require additional room for mobility aids or assistance.
Examples & Analogies
Think of accessible parking like having a special designated area for those with a larger vehicle. Just as a family van needs extra space to open the doors safely and comfortably, accessible parking provides that needed area for users to navigate with ease.
Turning Radius Specifications

Turning Radius 1500 mm diameter
Detailed Explanation
The turning radius is indicated as a minimum of 1500 mm in diameter. This specification is essential for allowing wheelchair users and individuals using other mobility devices to turn around easily in confined spaces, such as hallways or corners.
Examples & Analogies
Imagine trying to turn your bicycle in a narrow alley. If the alley is too tight, you will struggle. Similarly, a proper turning radius in building design makes it easier for wheelchair users to navigate spaces without hassle.
Toilet Specifications

Signup and Enroll to the course for listening the Audio Book
Toilet Size 2200 mm x 1500 mm
Detailed Explanation
Toilets designed for accessibility must be at least 2200 mm long and 1500 mm wide. These dimensions ensure that individuals using wheelchairs have sufficient space to maneuver and use the facilities comfortably without obstruction.
Examples & Analogies
Picture a bathroom stall that feels cramped. Just as a spacious bathroom allows everyone to use the facilities without feeling claustrophobic, adequate space in accessible toilets ensures comfort and usability for users with mobility needs.
Handrail Specifications

Signup and Enroll to the course for listening the Audio Book
Handrail Height 760 mm and 900 mm
Detailed Explanation
Handrails should be mounted at heights of 760 mm and 900 mm. This height range accommodates different user preferences and needs, including people depending on handrails for support while using ramps and stairs.
Examples & Analogies
Think of using a handrail like holding onto a safety bar when riding a bus or train. Just as the height of those bars is crucial for your balance and safety, the correct height for handrails helps individuals maintain stability as they navigate different levels.
Tactile Path Specifications
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Tactile Path Width 300 mm (min)
Detailed Explanation
Tactile paths must have a minimum width of 300 mm. These paths are designed for visually impaired individuals to navigate safely, using their sense of touch to follow the path and avoid obstacles.
Examples & Analogies
Consider the tactile path as a kind of textured guide, similar to walking on a cobbled street where you can feel the differences beneath your feet. Such paths help individuals with visual impairments navigate their environment confidently.
