Thanks guys. Well it is Maine Coast ledge. I will point out to the customer what's involved in terms of stability and the importance thereof. But I do know that the live load will be limited 90% of the time since this will be simply a few platforms and a run of maybe 8 steps at one point.
I'd say the slope is probably [from top to bottom] about 8-9' in a 15' run. Normally you would think unless they decide to have 30 people go up this stairway at once...your good with what I described above for an approach to do this. But the thing is, that's how this has to be planned (overkill). It only takes that one unplanned, unexpected situation for things to go badly very quickly.
12' round pier won't be neccessary though (I guess you need to see it Ron), but, deeper holes I agree with. I'll probably get a "rock guy" {tech term?????} and have him assess the situation.
Couldn't get pic's cause it's raining cat's-n-dog's right now. But I'll revisit this tread later.
Thanks again.
