It is not uncommon for the construction to be "top down". In other words,
the sheet piling is driven prior to the excavation taking place. After
excavating to the depth of the first row of tiebacks, the tiebacks are
installed. No cantilever condition for this method of construction other
than the short cantilever above the tieback.
Not saying this is the only way it's done, it's just the only way I've done
