They're generally in sheets that fit the freight elevators.
Some tenant improvements are concurrent with the shell and core construction and by the same contractor -- I don't know the guidelines, but definitely there's some pre-loading of large materials before enclosure. Other TIs are started after enclosure. Also, many TIs are while the building is complete and occupied, including both new buildouts and renovations. When the building is occupied, TIs generally involve night movement of materials and debris, and usually rely on the freight elevator. For a major occupied TI, you can pop a window or panel and bring in a mobile crane or other hoist, but that's a major cost and also disruptive to other tenants. It's usually limited to stuff that can't be delivered in pieces, like air handling units.
