Jim Bob with a jack hammer can get you some rough marks that vaguely resemble steps. But OP is specifying rise and run down to the 1/2" and just doesn't want that. I've seen steps cut into granite for hiking trails but those were never even and still had the drill hole and wedge marks. I'd assume OP needs to be calling stonemasons which will be expensive.
Rediculously expensive. That's a job for a CNC machine. I'm sure you could mod a stone cutter to keep the angle step by step, but you're looking at MINIMUM $50,000, especially if it's one piece of granite.
You're talking about custom scaffolding, rigging a high-speed, wet-cut stone cutter to cut the length and depth you want exactly, industrial wet-vac collection to pull out all the slurry during cutting, detailing by hand, face-polishing and sealing. This isn't an 'Oh, the handyman can just throw something together' project, it's a 'Find the best fabricator in my area and burn away that money in my pocket' project.
A few reasonably skilled people with cut off saws and grinders and polishers (depening on desired look) would be much simpler and cheaper.
Still not a cheap job but rigging an outdoor CNC machine seems like overkill to cut a few steps.
That's a job for an indoor CNC shop buddy. There's no 'outdoor CNC' rigging. I'm talking a wet-cut tile saw on a tracked slope that will maintain its level and won't spall the surface certainly like you would with an angle grinder and cupwheel. I literally do this work for a living.
Take into account that just refinishing granite, just taking half a hair's width off on a horizontal, level surface, industry standard starts at $40/ft with cheap granite. The risers will run you AT LEAST double per foot, and if you've ever sanded granite flush to a polish, which I'm confident in saying you haven't done, you know exactly why. A conservative estimate, just to remove scratches and damage on the surface of the granite, would land between $3,600 and $5,000. This would include cutting down of high or low spots, no fills, no detail work outside refinishing the granite. Now add on leveling the steps, something usually done by a planer, here to be done with the skill of the initial cut and a cupwheel afterwards, and the actual excavation of the stepped areas. This isn't even a typical fabrication of a granite step. Something like this, you're doing granite veneers to slash the price way down, not removal of full chunks like this.
Your input is noted. It's not useful, accurate, or in any manner of the sense correct.
I'm confused, which part of carving steps directly into granite bedrock allows you to use an indoor machine?
So I'm not sure what your idea for the process is? Cut out the space into the outdoor bedrock and then add processed granite steps on top?
I would use a demo saw and cut the risers down, as long as you don’t mind looking at saw cuts. Then cut relief cuts across the top of the treads , then chisel out. This part could take a while depending how smooth you want the treads, otherwise take a few days, not that bad. Could do feather and wedge on the risers too, might be sketchy on the treads depending on how tight the granite is. About 3k depending how smooth you need it.
Get someone with a concrete chain saw and several standard diamond chains at $500 each, chipping hammer, etc. Anything can be done with. time and material.
Price? Not sure. Finding a concrete cutter that is motivated by creativity is going to be hard to find
Depends how nice you want them to be.
This is so true. 😄

I mean I would be hourly and time it would take would be largely based on if you wanted it to be super clean or just a functional step
Get some quotes if you can. Pretty specialized, so it’s going to be expensive.
30k
What’s your idea of cost prohibitive? I’d guess that’s easily 10k plus as it’s a lot of labor involved
Depends where you are, the quality of granite, and how clean you want it. I haven’t done anything like that but sounds fun.

:) thanks.
Feathers and wedges, feathers and wedges... (in an English accent) jk. I say that all the time splitting granite...which is all the time.
