ADA ramp construction, what do you use to build ramp


Just wondering what is the recommended material for building an ADA ramp. What we have is 33" from the ground to threshold top. This is on a commerical coach and will be used for an office in California. We were hoping to have a deck running along the length(50 to 60 feet). We are planning on pouring a cement pad of about 6", and also for the parking stall. If we can get away from using cement on the ramp and using wood, except plywood. Has anyone used 6 X2 boards?

Check with the inspector. He's the guy you have to make happy.
1. Since you're doing so much concrete work, make it from concrete. The price won't be much different than wood, especially considering you'll have to replace it every few years.
2. I did one in wood at my church many, many years ago, but it was redone in concrete a few years ago while I was living out of state. Lots of ramps around here are being replaced with concrete, so I suspect the rules have changed *again*.
My brother-in-law, the architect, tells me that the ADA rules are very specific about dimensions, slopes, landings, turns, railings, traction, and the type of underwear worn by the carpenters. Go talk to the inspector before you make up your mind.

You can use pressure treated 2x6 and then cover with indoor outdoor carpet. I have built handicap ramps with 2x6 redwood and a concrete landing/transition from street level to first board. Anyway that is just a technical aspect so there is no bump on the start of the ramp. Yes, 2x6 boards can be used for a ramp in Calif. You can also use the composite wood with stainless screws.....This is a non-slip surface also. jloomis

I think that the cement will be our best bet. Another question. We will need to have the ramps reach a total height of about 28 inches, so this means a switch back ramp with 2 ramps at 14 feet. Is 14 feet to long of a run?

Elsewhere in the thread you've had the two pertinent responses --
the ADA guidelines document that gives requirements and to contact the local jurisdictional office of permitting, inspection, etc., to get any local code requirements as well.
What you'll have to do is satisfy those minimum requirements irregardless of what else somebody here tells you.

Hi Guy,
The maximum allowed rise for any run is 30" without a platform (landing). If your total rise is greater than that, add a platform and stretch the ramp accordingly, it's not that much extra work or cost, do it right and do it once.
Many years ago, I had a supervisor who used to preach" Why do we have the time and money to come back and fix it, when we didn't have the time or budget to do it right the first time?" That guy made a lasting impression on me more than 30 years ago that has never left me or failed me. Bottom line is do it right the first time and it'll never (almost) come back to bite you on the butt.

Go to the ADA website they will give you the details and all of the information that you require. You can build them out of wood or concrete, if wood use pressure treated lumber and I suggest that you use recycled materials for the deck also grip pads.
