The failure was supposedly in the connection between support columns and the horizontal slabs.

I saw a civil engineer comment that said the plans were missing column caps that strengthen the connection between columns and slabs..

That makes the collapse due in part at least to a design defect, in addition to construction defects and a lapse in maintenance. My guess is that the city of Seaside will also be cited for failure to properly inspect the building.
