Moddy is the ultimate tool for OTs to design ramps with precision in feet and inches.
Easily add a landing in seconds to meet requirements
Built-in calculators for running slope and rise
Modify length, width, height, and gradient to meet the client’s needs
Moddy measures ramps for you, even if you change their size.
Create reports that are understandable and suitable to submit to funding bodies within Australia.
A ramp should be included whenever there is a change in level greater than ½ inch that could impede mobility. This applies to entrances, thresholds, and interior transitions.
Additionally, if a walking surface has a slope steeper than 5%, it should be treated as a ramp to ensure smooth accessibility.
The minimum recommended width for a ramp is 36 inches between handrails to allow safe and unobstructed wheelchair passage.
In workspaces or areas with high traffic, a wider ramp may be necessary to accommodate maneuvering and assistive devices.
The ideal ramp slope should not exceed a 1:12 ratio (one inch of rise for every 12 inches of run). In space-limited areas, a steeper slope (1:10 or 1:8) may be used for short rises, but this should be minimized to reduce physical strain on users.
Handrails are required on both sides of ramps that have a rise greater than 6 inches.
They should be continuous, mounted 34 to 38 inches above the ramp surface, and extend at least 12 inches beyond the top and bottom for stability.
