We have a Schwing 39 meter placing boom going up with the octagonal mast with the freestanding tower. My question is for a freestanding tower in the Schwing Technical data book it shows the dimension for the pad that needs to be used but it doesn't show the strength of the concrete, rebar size, and the spacing of the rebar were looking for a structural drawing or an engineered drawing Schwing does not have this available so can anybody help me out with this I'd greatly appriciate it.

Schwing has no doubt given you the engineering data to hand over to the jobsite people. I have been through this process and found that once the jobsite engineers were given the information they were able to construct a suitable foundation for the mast and boom. It is like much of life; just because I don’t understand does not mean that those professional people in that field don’t know the solution. We are concrete pumpers. We are not engineers or electricians.
