Experts offer fund facts that can keep NYC moving

By Rachel Antman

People often ask industry leaders: “What keeps you up at night?” The answer from those in real estate may very well be “infrastructure.”

Daniel Rose, chairman of Rose Associates, Inc., has decried the “pot-holed roadways, structurally unsound bridges and over-crowded air flights,” that are “facts of life throughout the United States today.”

And during a CollabNet event last month, RXR EVP Seth Pinsky stressed the dangers that crumbling infrastructure poses to New York City’s otherwise bright future.

It was not surprising, therefore, that CollabNet’s subsequent event, “The U.S. Infrastructure Marketplace,” attracted a capacity crowd of real estate executives (including Mr. Rose).
