The total U.S hotel development pipeline shrank by 9 percent in October, according to that month’s STR/McGraw Hill Construction Dodge Pipeline Report. A total of 2,835 projects, representing 310,387 rooms, were in the pipeline. While STR expects new room supply growth to be weak over the coming years, New York City is proving to be an exception. “They are in the middle of a new hotel construction explosion,” noted STR vice president of global sales and marketing Vail Brown, in a statement. Rooms under construction in the New York City market represent about 7 percent of the city’s supply base. Nashville posted the largest increase in rooms in the construction phase, exceeding last year’s numbers by 333.1 percent.
