Heavy steelwork is decided by the piece that has to be lifted, not by the floor area. Section weight, plate thickness and the erection weight of a single member set the crane, the splice and the shop sequence.
01 / The parameters
Past a certain weight a member stops being a rolled section and becomes a piece of fabrication: plates cut, assembled, welded, straightened and drilled as one component. From that point the constraint is no longer the frame layout but the handling — what the shop crane can turn, what the truck can carry and what the site crane can lift in one piece. Heavy steelwork is planned around those three limits and detailed backwards from them.

When the load can no longer be carried by an available rolled section, or when the piece is large enough that handling governs. At that point the member is built up from plate — cut, assembled, welded and straightened as one component — and the drawing office has to plan the welding sequence and the lifting points as part of the design rather than leaving them to the shop.
By the sequence, not by straightening afterwards. The order of the passes, the balance of weld on each side of the web and the amount of restraint during assembly all decide how much the member moves. Heat-straightening a finished heavy member is slow, and it is the wrong place to solve a problem that the welding sequence could have avoided.
Yes, and it usually has to be — the limit is whichever comes first, the container, the truck or the crane at the far end. A split member needs a designed splice with matched holes and a connection that carries the forces the continuous member would have carried. That splice is detailed at drawing stage; it cannot be invented on site.
