Aside from some nice drone footage of 300 main it begins with the claim it is the "tallest DEALTABEAM structure in the world".
Can anyone add any information on this? It's obviously a promotional video for "Dealtabeam", which, according to my brief internet search, is some kind of pre-fab structure. Could this be why the build ended up taking so long?
