>Most skyscrapers are steel girder construction, and that was especially true in the 1980s, says John Cross of the American Iron & Steel Institute. Some use pre-cast concrete. Trump chose a costlier and in many ways riskier method: ready-mix concrete. Ready-mix has some advantages: it can speed up construction, and doesnโ€™t require costly fireproofing. But it must be poured quickly or it will harden in the delivery truck drums, ruining them as well as creating costly problems with the building itself. That leaves developers vulnerable to the unions: the worksite gate is union controlled, so even a brief labor slowdown can turn into an expensive disaster.
