Conduit depth in concrete

Is there anything in the code that gives a depth requirement for putting conduit in concrete?

As Justin brought up, if it is under a building it is 0", it can be in the pour. If not, it varies by wiring method. Where are putting the conduit and what is the conduit material?

Table 300.5, page 70-138 in the 2011 code.

I really wish Table 300.5 listed "In an interior slab" or "Encased in a concrete floor not subject to vehicular traffic," or something like that, rather than just "Under a building," for one of the locations.
