- Manhattan's latest skyscraper and tallest residential building is using
280 million pounds of iCrete concrete mixes, reducing greenhouse gases,
material costs, excavation time and labor.
- Strengths range from 6,000 psi to a top strength of 12,000 psi which is
demanded for the shear walls, columns and link beams.
- The use of iCrete for Beekman Tower means faster finishing times,
reduced shrinkage, durability, less creep, and greater resistance to
alkali-silica reactivity and freeze-thaw.
NEW YORK, Feb. 12 /PRNewswire/ -- (Excerpted with permission from the
pages of Concrete Today Magazine.) Rising majestically above the Manhattan
skyline, just blocks from the World Trade Center Complex, is one of the most
anticipated and historic construction projects undertaken since the original
WTC towers were erected more than 40 years ago. At 76 stories, the
$660-million Beekman Tower is destined to become the catalyst for the rebirth
of lower downtown Manhattan.
Designed by famed Los Angeles architect and Pritzker Architecture Prize
laureate Frank Gehry, the building will house 903 luxury residential
apartments, each with its own unique floor plan. Occupancy is expected in the
fall of 2010.
According to WSP Cantor Seinuk CEO Silvian Marcus, Beekman Tower will be
totally made of concrete, unlike the Freedom Tower, which was steel with a
concrete core. Indeed, when complete, Beekman will be the tallest residential
building in New York City.
Concrete contractors will place about 65,000 cubic yards of cast-in-place
reinforced, high-strength concrete on the main structure, with an additional
9,000 yards for the foundation. Upon completion, 280 million pounds of
concrete will have been used, ranging in strength from 6,000 to 11,000 psi.
According to Marcus, the shear walls, columns and link beams will be more than
12,000 psi. "Thanks to the high-performance concrete supplied to us by the
California firm, iCrete, we were able to use a low water-to-cement ratio,"
Marcus explained. "This allowed us to use 30 to 40 percent less cement."
The formula for the concrete mix, developed by iCrete, is, in and of
itself, a source for potential LEED points. iCrete touts a reduction of 40
percent in greenhouse gas emissions resulting from less cement paste needed to
bond the aggregates, reducing its carbon footprint. This also means less
material costs, less excavation and less labor. In addition, iCrete offers
faster finishing times, reduced shrinkage, durability, less creep, and greater
resistance to alkali-silica reactivity and freeze-thaw. It also relies on
less steel. (Copyright 2009, Concrete Today Magazine and Florida Media.)
