lift shaft
hi, this is odiodet. i have a lift shaft to design, although precast box elements are avilable and ready to apply, what woud you consider critical for a design?

check out our whitepaper library.
what you're lifting, how you're going to lift it - cables or hydraulics, how high you have to lift it, what is available for the suport of the foundation for it.
