What Is Selective Demolition? When Is It Applicable?

There are times when a part of a structure needs to be torn down or reworked to meet certain needs. It doesn’t always make economic or functional sense to rip everything apart and start from scratch. The solution is selective demotion.

Selective demolition, also referred to as precision demotion, is the process of demolishing specific materials or zones within a building or structure. It’s slightly different from interior demolition, which involves the complete demo of all interior elements of a structure. For example, a structure may need to be made higher, lower, wider, or safer. 

Selective demolition can also refer to the precise process of taking a structure apart. Instead of using explosives to blow it up or a crane to knock it down, this process is more precise. In other words, selective demolition techniques are preferred to preserve usable areas of the property and avoid the collateral damage that explosives can cause.

How Selective Demolition Works

Every selective demolition project is different, but here are a few key steps that characterize most successful projects.

Planning and Surveying

Any project that involves demolition will also require a significant amount of planning and preparation. Depending on the nature of the project, the contractor might need to invest in extensive site surveys and materials testing. 

The results of the testing and surveys will allow the team to create a detailed plan for execution. Specifically, what equipment, experience, and expertise will be required for the project? How long will it take to complete? What are the inevitable challenges that still require addressing?

“Cutting and Capping” Utilities

Another vital step to take before launching the project is to cut and cap any existing utility lines. This ensures there is no damage to the remaining structure during the project. Also, any part of the structure that will remain in operation could do so if this step is planned correctly. 

Obtaining Licenses, Permits, and Insurance

Many selective demolition projects are massive undertakings. They may require separate permits or the company may have to adhere to various state and federal regulations. Insurance and bonding for the specific project is generally a requirement. 

Emphasizing Safety

Precision demolition can also be dangerous work. One of the trademarks of a successful project is a company’s ability to achieve the desired goals without any major incidents or injuries. This happens through careful planning, experience, and strict safety procedures. 

Planning for Removal

One of the major benefits of selective demolition is that it’s a cleaner and more sustainable option. Instead of blowing everything to pieces, you have the opportunity to salvage and even reuse materials. Assuming you don’t want to reuse the materials, at least other parts of the property or structure won’t be damaged or destroyed by the process. It’s also a more environmentally friendly option. 

When Selective Demolition Might be Applicable to a Project

Selective demolition is applicable to a variety of projects in a variety of industries. Here are a few examples.

  • Heavy industrial — Various heavy industrial industries use selective demolition for projects related to power plants, steel mills, pulp and paper mills, and refineries. 
  • Offshore — Selective demolition even takes place offshore for things like marine applications, topside modifications, and platform segmentation. 
  • Heavy civil — The heavy civil industry uses precision demolition for projects related to ports, locks and dams, and highway bridges and railroad bridges. 
  • Nuclear — In the nuclear field, these services can be used for decommissioning, seismic upgrades, and steam generator replacement. 
  • Heavy metal — Heavy metal industries use these services for projects related to decommissioning and size reduction. Selective demolition is also used to cut large metal structures for forensic testing.
