How To Build A Handicap Access Ramp

What is the formula for a handicap ramp?

For commercial use when somebody is sitting in the wheelchair or scooter while it climbs the ramp, ADA recommends a 1:12 slope, which means that every 1″ of vertical rise requires at least 1′ (12″) of ramp length (5 degrees of incline). Example: A 24″ rise requires a minimum ramp length of 24′ (288″) (24 divided by 1).

What angle do you build a wheelchair ramp?

The ADA provides good direction about ratios for wheelchair ramp slopes. The commercial and public facility standard for slope is 1:12 (in inches) or about 5 degrees of incline. For those building ramps at home, the ratio can be as steep as 3:12 or almost 15 degrees.

How do I build a ramp for free?

The Habitat for Humanity provides a free handicapped ramp program for disabled, low-income and fixed income seniors. The program sends someone out to evaluate your house and to access your need for the home modification. The materials used to build the ramp are donated and volunteers help with building it.

Can I use plywood for a wheelchair ramp?

Q. Can I use plywood for a wheelchair ramp? For an indoor ramp, plywood might work, but when building a wheelchair ramp outdoors, use pressure-treated lumber.

How do you calculate ramp length?

How long of a ramp should I buy? Determining Ramp Length: Measure total rise (how many inches from lower level to upper level) and divide by the slope.

How do you calculate the slope of a wheelchair ramp?

Calculating the Slope Divide the length of the wheelchair ramp by the height. This will be the second number in your ratio. The first number is always one. If the ramp measures 12 feet long and the rise is 2 feet, you would divide 12 by 2 to get 6, and your ratio would be 1 to 6.

How long should a ramp be for 3 steps?

Here are some factors that should be considered: Stairs typically run about 7.5 inches high each so for three stairs a standard rise or height would be about 22 inches. The ADA [Americans with Disabilities Act] recommends 1 foot for ramp for every one inch of rise.

Do you need a building permit to build a ramp?

Building Permits and Approvals Most areas will require you to get a building permit to build a wheelchair ramp. Check with local building authorities to make sure you understand the requirements and that your ramp plan meets building codes.

How wide should a handicap ramp be?

The minimum inside width between the opposing handrails must be at least 36 inches to accommodate a wheelchair. This means the ramp must be built at least 42 inches wide to allow for the 1-1/2-inch spacing between the handrail and any surface and the actual 1-1/2-inch handrail.

What is the max slope for a handicap ramp?

Passing spaces (at least 1800m wide and 2000mm long) that allow two people using a wheelchair to travel in opposite directions at the same time. Landings or circulation spaces are provided at changes of direction, doors or gates. Maximum slope of a ramp that is longer than 1900mm is 1:14.

Does Medicare pay for wheelchair ramp?

Generally, Medicare will not pay for a wheelchair ramp. This is because Medicare Part B only subsidizes the cost of “Durable Medical Equipment” such as wheelchair ramps when they are deemed directly medically necessary by a licensed physician. That said, there may be exceptions under specific Medicare Advantage plans.

How do you cut the angle of a ramp?

Align the end of the straight edge with the mark and adjust the other end to produce the desired slope. Use the pencil to trace along the length of the straight edge creating a template of the slope and angle to be cut.

How thick should plywood be for a ramp?

You should plan ahead when surfacing the ramp, you would not want to let your ramp sit in the rain after putting down only the plywood or unpainted massonite (the massonite expesially will begin to warp the first time it gets rained on). The first two layers of the surface should always be 3/8″ untreated plywood.

What kind of wood is used for ramps?

Like a deck, ramps made from pressure treated wood are sturdy and resilient when properly built and maintained. Wood is more DIY-friendly than other options and can be made using common tools such as hand saws or circular saws for cutting the lumber and drills for driving screws for the framework and surface decking.

What is the best wood to use for a ramp?

The quality of wood dictates how strong and durable the plywood is. For instance, birch has phenomenal surface hardness, therefore birch plywood is one of the best. And a great choice as the riding surface for many indoor ramps. The plywood that we are concerned with are given grades, but only in the Unites States.

How steep can a ramp be?

The maximum recommended slope of ramps is 1:20. Steeper slopes may be allowed in special cases depending on the length to be covered (fig. 4). Ramps should be provided with landings for resting, maneuvering and avoiding excessive speed.

How much concrete do I need for a ramp?

Multiply the result from Step 2 by the width of the ramp to find the volume of concrete needed in cubic yards. Completing the example, if the ramp is 1.5 yards wide, you would multiply 1.5 square yards by 1.5 yards wide to get 2.25 cubic yards.

What is a 1 to 12 slope?

1:12 slope ratio (ADA Recommended) means that for every inch of rise, you will need one foot of ramp. As an example, a 12 inch rise would require a 12 foot ramp to achieve a 1:12 ratio. 2:12 slope ratio means that for every two inches of rise, you would need one foot of ramp.

Do all ramps need handrails?

Ramps having slopes steeper than 1:20 require handrails. Ramps with a rise greater than 6” require handrails. Handrails must be 34” – 38” in height measured above the walking surface. Handrails must extend at least 12” beyond the top and bottom of any ramp run.
