Mendes Caldeira Building
The Loizeaux family, which has blasted its way to the top of the demolition business in the U.S. (ENR 8/10/72 p. 24), last week outdid itself by bringing down a modern, 32-story building in downtown São Paulo, Brazil with a single blast. It had to make way for a large station for the city's rail transit system, already under construction on the same block.
Controlled Demolition, Inc. (CDI), Towson, Md., run by Jack Loizeaux, his wife Freddie and sons Mark and Douglas, placed nearly 1,000 lb. of explosives in the heavily reinforced concrete structure which was only 12 years old. "We put 777 charges on 11 floors, many more floors than is usual, to ensure that the building would come down safely," says Mark Loizeaux. "We were afraid even to make test shots because of the tremendous interdependency of structural elements."
