What is Selective Demolition?
Also referred to interior demolition, selective demolition uses carefully planned sequenced activities that separate and sort the materials within a building. Rather than knock a building down, an Oregon demolition company deconstructs it using special equipment. The solution reduces waste, maximizes efficiency and reduces a project’s carbon footprint. Building owners often seek this option when they want to update a structure’s interior, convert a space, improve the building’s health, or add an extension.

Selective Demolition Steps
Information Gathering and Project Planning
Selective demolition always starts with information gathering. After learning about a client’s goals, Oregon demolition specialists identify and survey materials that are salvageable, recyclable and hazardous. During the initial steps, contractors also review drawings, permits and grandfathered design elements.
Each municipality differs in regards to a building’s placement, use and size. While gathering information, a contractor learns what it can and cannot do by studying the city and county’s codes. Having a firm understanding of the regulations helps a contractor begin a project with confidence.
Codes that might affect a project include those related to:
- Maximum building height and area
- Local transit services
- Pedestrian safety
- Existing landscaping features
- Maximum possible envelope
- Existing structures
- Occupant comfort
- Allowable floor areas
- Noise levels
- Maximum allowable lot coverage
Many buildings that undergo selective demolition retain their main operative functions. Before removing building components with demolition equipment, specialists ensure the safety of the project and prepare materials for removal and recycling. This process involves cutting power to the respective area, capping pipes and turning off HVAC systems.
Depending on window placement and natural lighting levels, a contractor may install temporary lighting systems to improve visibility within the building. The crew may also install supportive shoring or bracing to prevent movement, settlements or collapses.
After learning about a client’s goals, learning the details about a building, securing the necessary permits and finalizing details, specialists strip the building. This step begins with protecting components a client wishes to keep and removing nonstructural materials, followed by the main demolition activities.
Nonstructural materials include:
- Light fixtures
- Plumbing fixtures
Green Oregon demolition services separate building materials, allowing a client to reuse, recycle or resell them. This not only diverts waste from landfills, it may also help offset project costs when a client resells, reuses or donates the materials.
Because of the quantity of debris that demolition projects create, extensive sorting is required. To reduce waste, a green contractor uses special equipment to tear down a building. Attaching shears to the end of an excavator, for example, allows workers to reach high components without relying on a wrecking ball. Concrete crushers turn concrete into gravel that a client can recycle or use for the building’s renovation. Powerful magnets separate scrap metal that a client can sell. As an Oregon demolition contractor disassembles a target structure, it sorts the building materials into different piles for disposal, delivery or recycling.
After the crew strips a structure’s mechanical, architectural and electrical elements, all that remains is a shell that is ready for remodeling, remediation or an extension.
