building-demolitionIn the construction industry, destroying old structures is just as important as building new ones. Demolition workers tear down anything from high-rise apartment buildings to bridges or factories. Demolition includes blasting, which is the use of explosives, and wrecking with the use of machinery and equipment. Operating engineers, also called heavy equipment operators, and hand laborers usually work for wrecking contractors. Blasters work for wrecking and blasting contractors. They may also work for general contractors helping to build roads, bridges, and dams.

For instance, they may have to use an oxyacetylene torch to cut steel braces in addition to using other wrecking equipment. They also consider the structure's surroundings. Using explosives in urban areas may be too dangerous. Also, local ordinances may restrict or ban the use of explosives.
