Demolition

Demolition (also known as razing and wrecking) is the science and engineering in safely and efficiently tearing down buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes.

The ICE Demolition Protocol is a British waste management protocol produced by EnviroCentre, in partnership with London Remade, for the Institution of Civil Engineers (ICE). It came out of a joint ICE and Institute of Waste Management group called the Resource Sustainability Initiative.

A bulldozer or dozer (also called a crawler) is a large tractor equipped with a metal blade at the front for pushing material (soil, sand, snow, rubble, or rock) during construction work. It travels most commonly on continuous tracks, though specialized models riding on large off-road tires are also produced. Its most popular accessory is a ripper, a large hook-like device mounted singly or in multiples in the rear to loosen dense materials.

Demolition of Ile-Arugbo is the decision of the Committee on Review of Property of Kwara state government, north-central Nigeria released on 1 July 2019 to reclaim the plots of land acquired by Dr. Olusola Saraki without proper documentation. Ile-Arugbo (Old peoples home) is located directly opposite the family house of Saraki's in Ilorin, Kwara state. The building was constructed on plots of land owned by Dr Saraki to foster for aged people who visited him during his lifetime. In 1970, the state acquired the land for the construction of the phase II of its secretariat which was later abandoned.

S.G. Loewendick & Sons, also known as Loewendick Demolition Contractors, is a demolition company based in Grove City, Ohio, a suburb of Columbus. The company is the largest specializing in demolition in Central Ohio. It has torn down most of the landmark buildings in Columbus in recent decades, including Union Station, the Ohio Penitentiary, the Christopher Inn, the Deshler Hotel, and the Ohio State University Drake Performance and Event Center.

Adamo Demolition (Adamo Group) is a Detroit-based asbestos remediation and demolition company founded in 1964 that specializes in industrial projects.

An explosive device is a device that relies on the exothermic reaction of an explosive material to provide a violent release of energy.

In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings. Despite its terminology, building implosion also includes the controlled demolition of other structures, like bridges, smokestacks, towers, and tunnels. This is typically done to save time and money of what would otherwise be an extensive demolition process with construction equipment, as well as to reduce construction workers exposure to infrastructure that is in severe disrepair.

Slighting is the deliberate damage of high-status buildings to reduce their value as military, administrative or social structures. This destruction of property is sometimes extended to the contents of buildings and the surrounding landscape. It is a phenomenon with complex motivations and was often used as a tool of control. Slighting spanned cultures and periods, with especially well-known examples from the English Civil War in the 17th century.

Ship breaking (also known as ship recycling, ship demolition, ship scrapping, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships either as a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about its use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries.
