Wheelchair Ramp Standards

The unifor federal Accessibility standards specify that the ramp angle used for a wheelchair ramp must be less than or equal to 4.78'.

The length of one ramp is 16 feet. The vertical rise is 14 inches. Estimate the ramp's horizontal distance and its ramp angle. Does this ramp meet the Uniform Federal Accessibility Standards?

The ramp is essentially a right triangle where the hypotenuse is 16 feet (192 inches) and the vertical side is 14 inches. Use the Pythagorean theorem to find the third side, the horizontal distance.

The ramp angle will be the angle in between the hypotenuse and the horizontal leg. Call this θ. Notice that sin(θ) = 14 / 192. Take the inverse sine to find θ. Is it less than or equal to 4.78 degrees?

It appears that the height of the porch here is the same as what is at our job site. In review of this porch, and its wheel chair ramp, it looks ...

The Uniform Federal Accessibility Standards specify that the ramp angle used for a wheelchair ramp must be less than or equal to 4.78.

If you want to build a ramp with a vertical rise of 6 inches and to minimize the horizontal distance taken up by the ramp,
how to draw a sketch showing the approximate dimensions of your ramp?

hypotnuse: 71.3 inches
short side: 6 inches
long side: 71 inches
angles: 4.78, 85.22, 90
now all you have to do is figure out where to put them (:

To meet safety standards, a wheelchair ramp must be built in the following proportion.

height : base length = 1 : 12

The wheelchair ramp at your school will be 0.9 metres high. What will the length of the ramp along the surface be? (Hint: Use the ratio above to find the base length first.)

And...

A standard Canadian football field (without the end zones) is about 101 metres by 59 metres. How much shorter is it to walk diagonally across the field than along two adjoining sides?

I got the other questions but am totally blank on these two. Any help would be very much appreciated. Thanks!!!

The formula you will be using for these questions is: a^2+b^2=c^2

1) For the first question, you are given a ratio
height : base length
Which is 1 : 12
Then you are given the height 0.9 m. With this, you can find the base length and then using the formula, you can find the length of the ramp.
So,
Since one metre in height gives you 12 m in base length, 0.9 m in height gives you 'x':
(You can write ratios as fractions):
1/12 = 0.9/x <-- solve for 'x'
10.8 m base length
Now use the pythagorean formula to solve for ramp length.
(Let a = height, b = base length, and c = ramp length)
a^2+b^2=c^2
0.9^2+10.8^2=c^2
0.81 + 116.64=c^2
c=sqrt(117.45)
c=10.837m
So your ramp length is 10.837m.


2) For the second question, you are asked to find the difference in the distance when you travel the two adjoining sides between travelling the diagonal. The field is a rectangle. One side is 101 m and the other is 59 m. The diagonal is your hypotenuse.
Use the formula to find the hypotenuse:
a^2+b^2=c^2
101^2+59^2=c^2
c=sqrt(13682)
c=116.97m
So, you would travel 116.97m if you diagonally.
If you travel the two adjoining sides, you would travel:
a + b = ?
101 + 59 = 160m

Therefore your difference is distance would be:
160 - 116.97 = 43.03m
So, you would walk 43.03 m less if you go diagonally.

A co-worker is holding a workshop in which they are presenting many different things related to accessible housing for people with disabilities. As a last minute thought, they wanted to add some ballpark figures for what it might cost a person to add certain accessibility-related renovations/ modifications to their home.

I am looking for contractors (in Canadian $$$ - Manitoba especially) who might be able to offer *really* rough estimate to these renovations. These estimates are just to give workshop participants an idea of what they might be getting into financially:

- the upper and lower cost of a wheelchair accessible ramp built up to the front entrance of a home four standard steps up, labour and materials in.

- the lower to upper cost of widing a standard 32" to a wheelchair accessible 36" door in a home

- the cost of lowering counters in a standard (~200 sq f) kitchen, dropped counters, no cupboards

- anything else you might have worked on?
I TOTALLY understand that it is nearly impossible ot give any kind of accurate estimate because prices vary by region and design, etc., etc.,. I'm more looking for a baseline and any feedback a contractor or jack-of-all trades might have would be greatly appreciated.

No offense a lot of detail to go through, and I assume the Canadian Dollar and costs are similar to the US. In the US, and perhaps Canada there are guidelines that dictate door openings, ramp grades, counter top levels, etc.

Even a most simple ramp could cost $400, in a charitable sense. I built one for my Mother for just under that cost. That was to purchase material and pay my cousin something, as we built the ramp in the dark, using vehicle headlights.

In a "Ballpark" sense, just to HANG a door should be fair at $75. To expand the structure surrounding an expanded door size, safely stabilizing it, and purchasing the proper door size, could cost $500 plus with finishing, each door. In some logic, one should assume that some DOORS might be eliminated. DOORS for the disabled, most especially in wheelchairs, are often as much a barrier and should open AWAY from them, unless the level they happen to on, in an some sense, allows room to back up, then move forward. Interior doors pose a problem in hanging, to allow access to a room, with a wheelchair perhaps, getting out of the chair, closing the door, and would more relate to bathrooms, in which case a door opening OUT would be more appropriate, certainly depending on the size and logistics of the room.

Lowering counters might be the least of any labor or cost issues, other than the fact that cabinets and drawers might exist, and have to be removed. That would be a consideration in a labor fee, as well as manipulating plumbing and electrical outlets. To deny that cupboards, LOW/ELEVATED storage space should be considered, denies the disabled a more realistic method of conducting what they might want as a more normal life.

The cost to do so, could be time and materials?

I do have a suggestion that has nothing to do with a profit motive.

I suggest you contact agencies that deal with issues related to Modifications for the disabled, and perhaps even more, you bring some disabled into your program, in their notions of NEED.

I was married to a woman, who has disabilities and they evolve as she ages. I have worked with the disabled, privately and through agencies, having to use very specific guidelines as well as personal desires of those clients.

I have seen, for example, TUB/Shower/Toilet BARS assumed to be viable, yet weren't. I installed Pull up bars for an elderly man, who found them useless, even in the directives suggested, as he lacked the strength to Pull himself out of his wheel chair.

No offense, but I suspect no one can ballpark, or exactly define cost to a consumer, until they specifically know the needs, and lack of abilities of that consumer in a one by one basis.

I'm working on a presation for class. I need to know on:
Standard
Electric
Sporty wheel chairs
Transportation
Ramps
Accessories

No one can tell you that, because no one keeps that kind of information.
