The New York Times reports that the tallest modular building in the world will soon rise at the Atlantic Yards in Brooklyn.  Part of a $4.9 billion project, the 34-story steel building will have 400 affordable apartments as part of its obligation, which also includes a new arena for the New York Nets NBA basketball team.  The 900 modules can be assembled by fewer and less-skilled workers than conventional construction.  While cutting costs in half, the size of the 16-building complex may make it worthwhile for the developers to operate their own modular factory.  It is the second largest construction project currently ongoing in New York, behind the World Trade Center.  MaryAnne Gilmartin, executive vice-president of developer Forest City Ratner, said, “The company is interested in modular, high-rise construction in an urban setting.  It’s driven by costs and efficiencies.” The New York building trades council is not pleased with modular construction.
