A report will be presented Thursday by the U.S. Commerce Department's National Institute of Standards and Technology regarding the collapse of World Trade Center Building 7 during the terror attacks of September 11, 2001.

The report on its findings and recommendations from its building and fire safety probe will be unveiled in Gaithersburg, Maryland.

WTC-7 was a 47-story building that collapsed nearly seven hours after the World Trade Center towers went down.

The report will identify the probable collapse sequence for the building and will recommend ways that building and fire safety in similar structures can be enhanced.

The original building was replaced with the new 7 World Trade Center which opened in 2006.

It's 52 stories tall and its design emphasizes safety, with a reinforced concrete core and thicker fireproofing of steel columns.
