Stairway down a rock cliff
Stairway down a rock cliff
(OP)
I am trying to design a stairway to decend a 100' rock cliff. What is the best method to secure the structure without too much rock drilling? My intial thoughts are to drill holes for rebar and pour small concrete pads on top of the rock at each post location. The access to each of these areas will be very limited.
Any thoughts?
Here are some pics of the proposed location.

You could then tie it back into the rock face at intervals to give it additional support, but you could do this from inside the stairwell - ie a safer working environment.

It would look much nicer.

I would like the stairs to blend in as good as possible to not take away from the view of the cliff.
As in the pictures posted. The only real concern is the first 30' drop. I figured a single staircase with one landing half way down. My intial thoughts are to pour small concrete pads with rebar drilled into the rock to support the stairway at the three locations; top, middle, and bottom.
The bottom half of the stairway is very straight forward.
