As the tallest building in Boston, the John Hancock Tower (now simply known as 200 Clarendon Street) was mired in controversy even before it was built. Generally, it is rare that a building is collapsed dur to foundation failure unless it is constructed on expansive soil. An additional 2,500 people were injured and rescued from the building, which housed a number of garment factories. The structure accommodates a shopping mall, apartments, restaurants and some service stores. /CS /DeviceRGB /P55 46 0 R However, construction of the tower couldn't be completed because of foundation problems discovered in early 2008.

On the 23rd floor, the slab started showing cracks and the failure of the building occurred vertically along the full height of the building, including the basement levels. The structural survey pointed out damage in multiple areas of the below-ground parking level. Or the steel reinforcing the columns in the parking garage or first few floors could have been so corroded that they somehow gave way on their own. << After the demolition of the building, it was also revealed that the quality of the grouted bearing surface for the joints between floors and the walls was poor.
