External Ramps

External Access Ramps

Here are some key aspects of external access ramps:

1. Ramps are sloped pathways that connect two different levels, such as a pavement or driveway and an entrance. The slope of an external access ramp is carefully designed to ensure it is within a specific range to allow for easy navigation by wheelchair users. The maximum allowable slope may vary depending on local building codes, but a common guideline is a 1:12 slope ratio. This means that for every 10cm of vertical rise, there should be 120cm of ramp length.
2. The width of an external access ramp is important to accommodate individuals using mobility aids and to allow for easy passage and turning. The minimum width prescribed by building codes is typically 90cm, but wider ramps are often recommended to enhance manoeuvrability and accommodate two-way traffic.
3. The surface of the ramp should be designed to provide traction and minimize slipping hazards. Common materials used for ramp surfaces include concrete, asphalt, wood, paving slabs or non-slip materials such as rubber or composite decking. The surface should be even and free from any obstacles or irregularities that could impede wheelchair movement.
4. At both the top and bottom of the ramp, level platforms called landings are required. Landings provide a resting area for individuals to navigate the transition between the ramp and the adjacent surface. They should be at least as wide as the ramp and have a length that allows for manoeuvrability and easy door operation. Depending on the space available and the height we sometimes need to put a landing within the ramp itself.
5. External access ramps generally require handrails and guardrails to provide stability, support, and safety. Handrails can be installed on one or both sides of the ramp and are positioned at a height between 86 to 97 cm to accommodate different users. Guardrails may be required along the sides of the ramp to prevent accidental falls.
6. External access ramps need to consider the surrounding landscape and ensure that there are no obstacles or vegetation that hinder safe passage. Clearances must be maintained to allow unobstructed movement along the ramp, and any adjacent elements such as curbs or steps should be appropriately designed for accessibility.

We always follow local building regulations and accessibility guidelines when designing or constructing external access ramps to ensure compliance with and provide safe and accessible routes for individuals with mobility impairments.
