I'd like to demolish concrete porch.
I’d like to demolish:
– the concrete stairs (it’s about 3’x3’x3’)
– the slab (about 3’x5’x5", all cracked with rusty rebars)
– the 2 brick columns
– the metal rebars and the T-shaped metal pieces on top of which the slab is placed
– the upper part of the wall (I think it’s made of cinder blocks) that’s behind the stairs (in pic 6)
Here is a Dropbox link to the pictures.
The whole porch is going to be re-done in wood so no need for any of the pieces.
I'd like to keep the concrete step underneath the door if possible.
How this can be done? What tools to use? What approach? How long would it take?
Best Answer
I'd budget two or three days if you're by yourself. The stairs will likely be the most time consuming. The slab is going to be obnoxious primarily because it's over that hole. It doesn't look like you can fit staging in there, and a ladder is problematic because falling debris can knock it over. I assume the dangers of demoing the slab while standing on it are self-evident. It's hard to say without a good look, but I suspect working backwards and into the door may be the best bet.
The Tools
In addition to the short list you'll probably want to rent an electric demolition hammer for one day. Apart from the obvious labor savings it's good insurance for the stairs; you won't need to buy more tools if they're exceptionally difficult to break down.
