New York, NY —

Hundreds of residents of a Manhattan apartment building are waiting to find out when they can go back home. They were forced to evacuate after a retaining wall at a neighboring construction site collapsed last night. No injuries have been reported.

REPORTER: A city Office of Emergency Management spokesman says no one has been allowed back into the 288 apartments at 784 Columbus Avenue yet. And the city Buildings Department says it expects to order 16 apartments to remain evacuated until they're safe to re-enter.

REPORTER:The Buildings Department says the wall's fall last night exposed part of the building's foundation, but the building is showing "no signs of distress."

REPORTER: The agency says preliminary reports indicate that blasting work earlier yesterday may have caused the collapse. Residents says the blasting was being done too close to their homes. The Buildings Department has halted work at the construction site, except for work required to bolster the wall.
