"In fact, living or working in a reinforced cast-in-place concrete building not only provides increased safety and fire protection, but it also "isolates sound" and in tall structures, "reduces the perception of motion caused by wind."
Jacob Grossman, President of Rosenwasser/Grossman Consulting Engineers of New York City.
"We find reinforced concrete to be the best material for high rise-buildings because it provides the best flexibility to
accommodate design needs, especially in residential
buildings, provides for comfort, redundancy, safety and
fireproofing and all at relatively reasonable prices."
Andrew Weiss, Executive Vice President, The Trump Organization.
"The more concrete, the more fire resistance; and the more concrete the less probability of total collapse."
