17 Floors Fold On Unfinished Building Block

No one was hurt, but neighbors were terrified Wednesday when a whole side of an unfinished 17-story apartment building on Michurinsky Prospekt in south-western Moscow crashed to the ground.

"We heard a loud rumble, and then the teacher let us out of math class," said Kolya, a second-grader who lives across the street from the site.

The building collapsed at 1:30 p.m., and shortly afterward masonry floors and supporting walls could be seen shattered on the ground or dangling half-way up the hulk of the apartment tower.

Workers who came to the scene said construction had been under way at the city-owned site for two years but that work was stopped last winter because the city ran out of money for the project.

A Moscow police officer at the scene, who asked not to be identified, said the side of the building had probably collapsed because a water pipe had burst underneath the building, making the ground soggy and soft.

Although a more careful inspection was needed, the official said most likely the building would have to be razed because it was too damaged for repair.

The construction site is just blocks from the Luzhniki sports complex, a $100-million renovation project opened in grand style for Moscow's 850th anniversary bash.
