This is an older shot I neglected to post, showing where Levi's flagship store was removed in preparation for Apple's flagship store construction. The interesting part is that it is on top of underground levels of the Grand Hyatt Union Square; not only challenging weight wise, but also because the hotel's service/loading dock entrance (the long structure along the right side) remains in use.
The Levi's store had extensively renovated the triangular wing that was originally part of the hotel, featuring their very large Plaza Restaurant (named after the Plaza Hotel that had once occupied the site). Apple obviously removed the entire super structure in order to build a completely new one--what a great lease for the Hyatt's owners! Construction of the Union Square Station for the Central Subway is on Stockton Street in the background.
