What Is Demolition?
Definition: Demolition is the planned dismantling, razing, or removal of a structure or part of a structure. It ranges from complete demolition of entire buildings to selective demolition, in which specific elements — such as interior finishes, floors, walls, roofs, facades, or equipment — are removed while the rest of the structure remains. Demolition work is planned around the building's condition, hazardous materials, adjacent structures, and how debris will be safely removed.
Demolition is far more than tearing a building down. Before work begins, the structure must be surveyed to understand its condition and the risk of unplanned collapse, utilities must be shut off and capped, and hazardous materials such as asbestos and lead must be identified and properly handled. On occupied sites, urban lots, and renovations, demolition must be sequenced to protect the remaining structure, adjacent buildings, and the public below.
That is why demolition so often depends on access and support systems. Scaffolding provides access for hand and selective demolition, facade removal, and protection of neighboring properties. Shoring supports floors and walls that remain or that are weakened during demolition. Debris netting, sidewalk sheds, catch fans, and dust containment keep falling material and dust from reaching people and property. Through Scaffold Exchange, you can find demolition contractors across the U.S. and compare their capabilities and availability.
Types of Demolition Services
Demolition contractors offer a range of services depending on the structure, site, and project goals.
Structural Demolition
Full removal of buildings and structures using mechanical equipment, high-reach excavators, or sequenced hand and machine demolition.
Interior & Selective Demolition
Removal of interior finishes, walls, ceilings, mechanical systems, and specific components while preserving the remaining structure.
Facade & Roof Removal
Removal of cladding, masonry, curtain wall, and roofing, often from scaffolding with debris containment and public protection.
Concrete Cutting & Removal
Saw cutting, coring, breaking, and removal of slabs, walls, and foundations, including openings in existing structures.
Industrial & Plant Demolition
Dismantling of tanks, vessels, piping, equipment, and structures at plants, refineries, and industrial sites.
Common Applications & Project Types
Demolition services are used on commercial, residential, industrial, and infrastructure projects throughout the United States.
Commercial building demolition for redevelopment
Interior gut renovations and tenant improvements
Facade retention projects that preserve historic fronts
Industrial plant and equipment decommissioning
Parking structure and bridge removal
Fire, storm, and structurally damaged buildings
Urban sites adjacent to occupied buildings
Concrete removal for new openings and additions
How Demolition Compares to Related Services
Demolition is often coordinated with other specialty services. Here is how it compares to related services and which situations each suits best.
Removal of asbestos materials
- Regulated removal and disposal
- Required before demolition disturbs asbestos
- Containment and trained workers
- Best before renovation or demolition begins
Repair and protection of concrete
- Repairs rather than removes structures
- Spall repair and crack injection
- Corroded rebar treatment and strengthening
- Best when structures can be saved
Planned removal of structures
- Complete and selective demolition
- Engineering survey and sequencing
- Scaffolding, shoring, and containment
- Best when structures or elements must come out
Installed debris containment
- Netting on scaffolds, fans, and openings
- Contains falling demolition debris
- Protects the public and adjacent property
- Best for facade and urban demolition
Control of dust and overspray
- Enclosures, sheeting, and barriers
- Controls demolition and cutting dust
- Protects nearby people and property
- Best for work near occupied areas

OSHA Compliance & Safety Standards
Demolition on U.S. job sites is governed by OSHA 29 CFR 1926 Subpart T, Demolition. Standard 29 CFR 1926.850 requires an engineering survey by a competent person before work begins to determine the condition of the framing, floors, and walls and the possibility of unplanned collapse, along with shutting off or controlling utilities and shoring or bracing damaged structures. Hazardous materials such as asbestos and lead must be evaluated and handled under their own OSHA and EPA requirements before demolition disturbs them.
- Engineering survey by a competent person before work begins
- Utilities shut off, capped, or otherwise controlled
- Asbestos, lead, and other hazards identified and addressed first
- Walls and floors shored or braced where the structure is damaged
- Debris chutes, openings, and drop zones guarded and controlled
- Public and adjacent property protected from falling debris and dust
