We built a ramp at our house and one at my Grandmother-In-Law's house. In a weekend. This is a great program because they will come and take the modules away and reassemble them at someone else's house when you're done with the ramp.
We made it a family project. Everyone learned to use power drills and a circular saw. Our decking crew was 12 and 14 and they did a spectacular job. The way Allen and I split the work was that he hung each section and I got them built. Hanging means leveling and some big carriage bolt screws. Earthwork. I ran the saws and the drills making each module. Our crew was done early and we then rearranged the existing concrete by using a sledge hammer to break it up and then make a mosaic 'landing pad' at the bottom. It beats the cost of garbage to reuse concrete. And the young men love using sledge hammers! A wheelbarrow is a godsend, as they all want to carry heavy concrete pieces and that's not a good idea. My mother-in-law is delighted to have a wheelbarrow left over from the project.
We have a ramp because it's easier for so many of our friends to come visit. Those who use walkers, canes, or are just not completely sure on their feet, are grateful. I would have loved a ramp during the days I was spraining my ankle regularly.
And idea. Use it if it makes sense for you.
