I sub-contracted another ramp for Abbey Medical at a nearby property. They put in an outdoor stairlift but needed a wheelchair ramp to get down a 7.5″ curved step. To get the proper grade, the step needed to have a straight edge, and a landing needed to be added beside the sidewalk.
I traced the curve on a piece of plywood and then pre-made that piece at my shop.
Next I dug down a few inches into the grass and placed some gravel and patio pavers. Lastly I made a 2×4 frame and screwed on the ramp.
