The most powerful giant machines in the world. The engineers went crazy.

 Dinosaurs are not dead and gone , they've been resurrected as  machines doing the hard work for us. Tell me that machine destroying the building don't look like a T-Rex .
Lol
 Wow . Nice . International union of operating engineers  / hoisting and portable engineers  . Make the world turn in a big way . Long live Operaters .
 It looked like most of these machines were in the design stage . Realistic graphics used to sell the project.
