You would be correct:
DDS 2019 CBC:
CAISSONS ONLY (VERTICAL PENETRATION ONLY) PERMIT FOR THE NEW CONSTRUCTION OF A 72 STORY HIGH RISE RESIDENTIAL BUILDING (635 DWELLING UNITS) WITH 3 BASEMENT LEVELS. ALL CAISSONS TO BE
DRILLED FROM EXISTING GRADE. (OCC GROUPS: R-2, S-2, A-2, A-3, B; CONST I-A) CONSULTANT REVIEWER: GLOBETROTTERS ENGINEERING
source: permit #100960347
I'm no structural engineer but I don't think piles would provide sufficient support for a 72 story building. Unless piles was being used interchangeably with caissons.
