It seems these days everything is built with rebar and poured concrete. All our buildings, all our bridges, everything. Years ago this would have been steel frame construction using girders and steel sheet flooring.
Why is concrete/rebar cheaper? Seems like there's a lot of framing work to be done before each pour and lots of complicated rebar bending and placing. Are the materials dramatically cheaper?
I'm baffled.
