18. Design Checklists (As per NBC Part 3)

Ramp Width Min. 1200 mm Ramp Slope Max. 1:12

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.

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 Width Min. 900 mm

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.

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 Cabin Size 1100 mm x 1400 mm (min), 2000 mm x 1500 mm (stretcher)

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.

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 3600 mm x 5000 mm

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.

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 1500 mm diameter

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.

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 Size 2200 mm x 1500 mm

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.

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 Height 760 mm and 900 mm

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.

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 Width 300 mm (min)

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.

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.
