In an October issue report, Good Days at Ground Zero, Esquire editor at large Scott Raab tracks first hand mid-summer delivery of a 10-yd, 12,000-psi mix load from Ferrara Bros. Brooklyn, N.Y., plant to the World Trade Center site. During a six-mile ride to lower Manhattan, veteran driver Lenny enlightens his passenger on the 90-minute delivery principle; use of shredded ice to maintain the 75-degree mix temperature target; and, tight truck-routing at a 16-acre site where Tower 4, the job Ferrara is supplying, is set for a 260-yd. pour.
After a brief but substantive look at concrete basics, Raab bluntly details how Chris Ward, executive director of site-owner Port Authority of New York and New Jersey Authority, has expedited work at the former hole in the ground since his mid-2008 appointment. By compelling architects, engineers and public or private entities involved in the major redevelopment projectsÛ1 World Trade Center, Towers 2, 3, 4, WTC Transit Hub and 9/11 Memorial and MuseumÛto revisit budgets and scheduling, the Port Authority chief has established a five-year construction window netting 10 million sq. ft. of office space and expansive tributes to those lost in September 2001.
Work is especially advancing, Raab notes, on two points set for SeptemberÒDecember 2011 completion and top out, respectively: the black granite-lined memorial pools, built by black hardhat-protected crews in the original WTC 1&2/Twin TowersÌ footprints; and, the 1,776-ft. (including spire) 1 WTC, pacing a 50th level this fall. The steel-framed tower rests on a deep, complicated foundation requiring 50,000 yd., which Quadrozzi Concrete Corp. supplied from a Brooklyn plant near the Ferrara operation.
