Building demolition is the process of tearing down structures to clear space for new construction or to remove unsafe buildings. This can involve various methods, including mechanical demolition, where heavy machinery like excavators is used, and controlled demolition, which employs explosives to bring down a building safely. Demolition projects require careful planning and adherence to safety regulations. Before demolition begins, assessments are conducted to identify hazardous materials, such as asbestos or lead paint, that must be handled properly. Proper waste disposal and recycling of materials are also important aspects of the demolition process to minimize environmental impact.
