demolir

Demolir is a verb meaning to destroy or tear down a structure. In Portuguese, demolir is the infinitive form and is used to describe the intentional destruction of buildings and other man-made structures. The word traces to Latin demolere, formed with de- indicating removal and molere meaning to grind down or crush; it entered Romance languages such as French as démolir and spread to others. In modern usage, demolir covers the complete razing of a structure and, in a broader sense, the dismantling of facilities.

Typical demolition methods include mechanical demolition, where equipment such as excavators and wrecking balls are used; implosion, which relies on controlled explosive charges to collapse a structure; and selective demolition, where target components are removed for reuse or recycling. Deconstruction is a related approach focusing on preserving materials for reuse rather than destroying them.

Demolition is subject to legal and safety requirements. Permits and planning are needed, and work is performed by licensed contractors under safety regulations. Hazards include structural instability, hazardous materials such as asbestos, lead paint, and dust; isolation of utilities; and safeguarding neighboring properties. Environmental considerations emphasize waste management, recycling of concrete and steel, and preservation of historic or culturally significant structures. Costs, urban policy, and community impact influence decisions about whether to demolish, retrofit, or redevelop a site.
