The Rebuilding of Ground Zero, Part 93

Yet another study of ongoing construction deadlines finds that delays are likely to push completion of key infrastructure and projects around Ground Zero into 2015 and beyond.

The review by the feds, obtained by The Post through a Freedom of Information request, gives the PA just a 25 percent chance of getting the massive project done by the authority's latest target date of mid-2014 -- a deadline three years later than originally planned.

The FTA's analysis also warns that even the feds' mid-2015 projected completion date could also falter because of unresolved delays in building two of Ground Zero developer Larry Silverstein's soaring office towers planned for either side of the transit hub.

"Construction of Towers 2 and 3 could become the most significant source of risks associated with the [transit] project," the report found.

Silverstein and the Port Authority are now in talks over how to move forward with construction of his WTC towers. They have about a month to reach an agreement.

Meanwhile, the Ground Zero Performing Arts Center has received a go ahead for construction to start next quarter. The LMDC is putting $50 million up for the center (but expect those costs to soar).
