July 8 (UPI) -- New York City officials believe they have stabilized a high-rise apartment building Wednesday in Midtown Manhattan after it began to buckle a day earlier.

Construction workers have added temporary support to the structure to prevent it from collapsing. However, the building, and three more in the area, remain under evacuation orders.

Construction crews continue to work on the high-rise structure Wednesday. It is a former office building that served as the headquarters for Pfizer and is being converted into luxury apartments.

The 37-floor building was evacuated Tuesday when construction workers noticed signs that it may collapse, such as multiple floors caving in and bricks falling from its facade.
