Digging into a basement

[Zak Marinko]

Does anyone have any referrals for digging into a basement to make the ceiling height acceptable? Any advice or connections in converting a basement into livable space would be greatly appreciated. Thanks!

To further clarify, like others have said sometimes if you only need a few inches to pass code for headroom (ceiling height)  sometimes you can obtain this if your existing footers are far enough below the slab to accommodate the needed CH.

in the diagram you can see that there is some room to lower the slab before interfering w the footing. 

in my area when someone considers this it's usually to gain a foot or more of room which leads to the underpinning option and costs.
