Milestone marked for new Center City apartment tower



A significant milestone that marks the early progress of the construction of a new apartment building was achieved over the weekend.

A 20-hour concrete pour was completed for the foundation of 1213 Walnut St., a 26-story tower that will have 322 apartments.


Hunter Roberts is the general contractor for the development of the building, that many know from its former name, the Fergie Tower. The developer is a venture among Goldenberg Group of Blue Bell, Pa., Hines of Houston, and ASB Real Estate Investments of Washington D.C.

These concrete pours are technical events and involve closing down streets and choreographing a convoy of trucks to construction sites. They most often happen in the early morning hours to cause as little disruption as possible and this occasion was no different. The process started at 3 a.m. on Saturday.

Some notable facts:

  • 300 truck loads of concrete were delivered;
  • 8,400 tons of concrete went for the foundation;
  • 4,200 yards went for the foundation;
  • 375 yards is used for a typical floor; and
  • 400 tons of rebar was involved.

By comparison, for the Comcast Center for Innovation & Technology, 400 trucks hauled in 4,000 yards of concrete that went into a 10-foot thick, 14-million-pound foundation that supports the 59-story skyscraper under construction at 18th and Arch streets.
