To these old eyes, that scene looks very much like:
1) At least two fairly energetic demolition charges along the near side of the building. (Carefully located to restrict blast effects to "warehouse" while sparing the "office building" immediately to the right)
2) Perhaps three smaller charges at each of the "loading docks"(?) on the left end. (Again located to prevent damage to structures adjacent further to the left.)

I can’t believe the news drops today that are supposedly such big “booms” are stuff we’ve known for YEARS.
