Jon Lentz reports for City & State on what the $1.5 billion pricetag for Dubai's Burj Khalifa would--or wouldn't--build in New York. Could New York City's construction costs, which are among the highest in the nation, discourage investment and push developers to build elsewhere? "That's the big fear: Have we reached the threshold, or when will we reach the threshold, that people will chose not to build here and build somewhere else instead?" said Hope Cohen, the associate director of the Regional Plan Association's Center for Urban Innovation. "And that goes directly to a question of New York's competitiveness, within the nation and also globally."
