A Brief Word... CONSTRUCTION • PUBLIC WORKS • NATURAL RESOURCES English Edition Volume 21 Number 3 March 2016 Forgive me for a bit of self-indulgence in this issue but, as I write this, I have learned some tragic news about a former colleague.

Using high strength “ASTM A1035 is now the only 100 ksi designs employing the 100,000 psi yield Grade 100 rebar, such as ChrōmX 2100 reinforcing steel allowed in any New York strength of ASTM A1035/A1035M-15 rebar, (ASTM A1035), in high rises allows for structure, the only reinforcement over clearing the way for applications of MMFX substantial reduction in steel of up to 40%, 80 ksi that can be used in beams and slabs, and the only 100 ksi reinforcement that can be used in Seismic Design Categories A, B and C,” said Tom Russo, MMFX Steel Corporation CEO. “Designing at these higher strengths using this new bulletin and ChrōmX (A1035) rebar will result in up-front construction cost savings, as well as increased construction efficiencies and eased logistics, benefiting contractors, developers and city residents.” Specifically, Buildings Bulletin 2015- 036 allows designs up to 100,000 psi yield using ASTM A1035 reinforcement in accordance with ACI 318, as modified by ACI ITG 6R-10 and ICC-ES AC429. The bulletin allows applications of ASTM A1035 Grade 100 reinforcement in longitudinal and transverse members, including slabs and beams, in Seismic Design Categories A, B and C. With the adoption of Buildings Bul- letin 2015-036, New York City joins other major high rise markets such as Miami and Seattle that are already applying high strength rebar designs in high rise towers. The timing of this bulletin is beneficial to design teams and developers with high rise projects planned across New York City. These projects stand to immediately ben- efit from applications of high strength steel designs as they reach higher and higher to make the most of the city’s precious real estate. For example, the 111 West 57th Street residential tower being constructed by JDS Construction Group in partnership with Property Markets Group will reach over 426 m into the sky. With a width to height ratio of only 1:23, it will be the narrowest tower in the world. Other projects currently in planning and construction such as One Vanderbilt (461.4 m), Nordstrom Tower (472.4 m), 432 Park Avenue (425.5 m), and 53 West 53rd (381.0 m) could have clearly benefitted from high strength designs. The new bulletin provides opportunities for the InfraStructures English Edition March 2016 – page 4 many towers and skyscrapers in design to construction project management platform. 12.81 of its Trimble® GCS900 Grade Control realize the advantages of 100 ksi reinforce- Many of our customers have applications System.
