Replacing pier and beam with slab foundation

[Milind Shastri]

Has anyone poured a slab in-place of an existing pier and beam foundation? 

I've acquired a property where the current condition of the pier and beam is quite bad. I'm considering jacking the house up and pouring a slab foundation, as this a way cheaper option (1/2x) than installing new piers. Any idea if this could conceptually work; I will be getting foundation plans subsequently but am just getting a preliminary understanding. 

Thanks!
