Specification for pumping/pouring concrete
(OP)
I am trying to find the Building Code/ACI reference specifying the maximum height of free fall of concrete for placement in reinforced steel structures. Can anybody help me with the code reference?

It provides a brief discussion followed by some good references.

I've heard about that but never have seen the practice since many organizations will allow only a maximum of 5'. After that a section of pipe or trunks with hoppers are necessary.
Many of the books on construction inspection have the 5' drop height referenced but no back-up or explanation. The same is true for most state DOT's that I've worked with in the past.
