Directions: Use this worksheet to record your answers to the questions or problems for the ADA Ramp portfolio. Where indicated, draw figures on a blank sheet of paper or on a sheet of graph paper. Be sure to label each sheet so that your teacher knows which answer goes with which question. You can scan these figures and submit them as individual documents with your portfolio worksheet, or you can take pictures of them and insert the pictures on the portfolio worksheet. Day 1 Design a wheelchair ramp for an entrance that is between 12 and 30 inches above ground level. Your design must meet ADA guidelines. To submit your design, do the following: A. State how many inches above ground level the door is and your chosen ramp angle.

Answer 1

To design a wheelchair ramp that meets ADA guidelines, consider the following:

A. State the Height and Ramp Angle

• Height of the door above ground level: 24 inches (this is an example and can be adjusted to any value between 12 and 30 inches as needed).
• Chosen ramp angle: 1:12 (which is the maximum recommended slope according to ADA guidelines). This means that for every inch of vertical rise, there should be at least 12 inches of ramp run.

Calculating the Ramp Length

Using the chosen height and slope, calculate the length of the ramp needed:

1. Vertical rise (height): 24 inches
2. Slope ratio: 1:12

Using the formula for the length of the ramp:

\[ \text{Ramp Length} = \text{Vertical rise} \times 12 \]

\[ \text{Ramp Length} = 24 \text{ inches} \times 12 = 288 \text{ inches} \]

Summary

1. Height of the door: 24 inches
2. Ramp angle/slope: 1:12
3. Ramp length required: 288 inches (or 24 feet)

You may now draw a figure of the ramp design with the appropriate dimensions, labeling the height, length, and the angle or slope. Once that is complete, you can take a picture or scan the figure to include in your portfolio.
