As For All Those Union Jobs . . .

. . . they were (pre-)fabricated:

And this week, Forest City Ratner confirmed that it was considering erecting a 34-story prefabricated, or modular, tower, as a way of cutting its construction costs and fulfilling its obligation to start building housing.

The construction unions that Mr. Ratner had lauded last year for sticking with him were stunned by the suggestion that much of the work might take place in a factory, where wages are much lower than on-site. Forest City has put off the start date for the tower, the first of 16, until the end of the year.
