Original 4 World Trade Center — Southeast Plaza Building
Joseph worked on the original 4 World Trade Center in its completion year. On 9/11, much of the nine-story building was destroyed by the collapse of the South Tower; damaged remnants survived briefly before being removed during the Ground Zero cleanup. A new 4 WTC later rose on the rebuilt campus.

“S.E. Plaza - World Trade Center — 1975”
The original 4 WTC was completed in 1975. FEMA classified it as a partial collapse after 9/11, while the 9/11 Memorial & Museum describes it as damaged beyond repair. Remaining portions were later removed; the current 72-story 4 WTC opened in 2013.
One of the strongest family-to-city-history connections in the archive, but one that requires careful language: Joseph worked on a 1975 building that was largely destroyed and rendered unsalvageable on 9/11, with remnants later removed during cleanup. The 4 WTC designation now belongs to a completely different tower on the rebuilt World Trade Center campus.
What Kelly did here
Family source
Probable
Likely: selective masonry alteration/restoration: likely brick or stone repair/rebuilding, repointing, opening/infill work, plus new CMU/block backing or partitions where the renovation required them.
This scope is recorded as probable, not documented. It is a disciplined reading of the building and the trade practice of the period, not a contract-level record of Kelly’s work.

The current 4 World Trade Center is a 72-story, 2.3-million-square-foot office tower designed by Fumihiko Maki at 150 Greenwich Street. Opened in November 2013, it remains in active office use on the rebuilt World Trade Center campus.
