Slight correction...they are using Auger Cast Piles capped with concrete caps...Berkel is a national deep foundation system/auger cast pile subcontractor who has recently opened a Philly area office given the amount of activity in the city...given the right subsurface conditions and load requirements, auger cast piles can often be more economical than caissons....an an example, 500 Walnut was originally designed as a caisson job, but was value-engineered/redesigned to use auger cast piles...
