Frequently Asked Questions (FAQs)

Why is interior demolition important?

Interior demolition is an important part of the construction process. It helps to create a clean work site and ensures that all materials are properly removed from the premises.  

In addition, selective demolition helps to prepare a space for new construction. By removing old fixtures, flooring, and debris, contractors can create a blank canvas ready for new building projects. Knocking down walls and partitions, allows for new layouts and open floor plans to be created, providing more flexibility and efficiency in the use of the space. By gutting an old space, contractors can update the electrical, plumbing, and HVAC systems to meet the needs of new occupants.  

Overall, interior demolition is essential for enhancing buildings, adapting spaces to changing needs, improving safety, and facilitating modernization. When carried out responsibly and with proper planning, interior demolition can lead to significant positive changes and benefits for the property and its occupants.

What are the differences between structural and non-structural demolition?

Structural and non-structural demolition refer to two different types of demolition based on the elements being removed from a building or structure. The distinction lies in whether the components being demolished are load-bearing (structural) or non-load-bearing (non-structural). Let’s explore each type:

Structural Demolition: Structural demolition involves the removal of load-bearing elements of a building or structure. Load-bearing elements support the weight of the entire structure and transfer loads down to the foundation. The purpose of structural demolition is typically to alter the building’s fundamental layout, remove an entire section, or demolish the entire structure.

Examples of load-bearing elements that might be removed during structural demolition include:

  • Load-bearing walls: Walls that support the weight of the floors or roof above them.
  • Columns and beams: Vertical and horizontal elements that carry the loads from the above structure.

Structural demolition requires careful planning and engineering expertise to ensure the stability of the remaining structure during and after the removal process.

Non-Structural Demolition: Non-structural demolition involves the removal of elements within a building that are not load-bearing and do not significantly impact the overall stability of the structure. Nonstructural demolition is typically less expensive and less disruptive than structural demolition. This type of interior demolition is often intended for renovating or repurposing a space, updating interior design, or removing non-essential components.

Examples of non-structural elements that might be removed during non-structural demolition include:

  • Interior walls: Partitions that do not carry loads from above.
  • Ceilings: Non-load-bearing ceilings that can be replaced or altered.
  • Floors: Non-load-bearing flooring materials.
  • Fixtures and fittings: Non-essential items like cabinets, sinks, lighting fixtures, etc.

Regardless of the type of demolition, it is important to consider the potential impacts of your project, such as environmental remediation, which includes:

  • Asbestos Abatement (found in ceiling tiles, flooring, insulation) 
  • Lead Abatement (found in pipes and paint) 
  • Mold Remediation (found after a flood, broken water pipes and leaking roofs) 

How long does interior demolition usually take?

Smaller projects may take only a few days, while larger building demolition projects can take weeks. The duration of interior demolition varies depending on the project’s size, the work’s complexity, and the specific elements being removed. If you need your job completed on a specific timeline, we are happy to work with you and our estimators will find the best time for the work to be scheduled and completed.

What permits are required for my interior building renovations?

The permits required for interior demolition vary depending on local regulations and the scope of the project. Commonly, building permits and possibly permits for hazardous materials removal are needed. During the planning phase of your project, O’ROURKE will identify and obtain the necessary permits to complete the work.

Can demolition be done on occupied buildings?

Yes, interior demolition can be carried out in occupied buildings, but it requires careful planning and coordination to ensure minimal disruption to occupants. If you plan to have occupants continue in the building during the project, we will take additional measures like containment barriers, ventilation systems, and work schedule adjustments to facilitate a smooth demolition process.

Is demolition dangerous?

Demolition can be hazardous if not conducted properly. Potential risks include exposure to hazardous materials like asbestos or lead paint, structural instability if load-bearing elements are not identified correctly, and accidents during demolition. Hiring experienced professionals, like O’ROURKE’s demolition specialists, is essential to minimize risks and safety concerns.

What if there is asbestos in the building?

If there is asbestos in the building, special precautions and procedures must be followed during the interior demolition process. Asbestos is a hazardous material that poses serious health risks when its fibers are released into the air and inhaled. Prolonged exposure to asbestos can lead to severe respiratory issues and even fatal diseases.

Handling asbestos during demolition requires compliance with federal, state, and local regulations to protect the health and safety of workers and occupants. O’ROURKE can perform hazardous materials abatement as part of any interior demolition project. Our licensed and highly trained team will safely remove, legally dispose of, and document all hazardous materials, such as asbestos, mold, and lead.

How do you handle the removal of debris after a project?

Handling debris removal during and after a demolition project is a crucial step. Proper disposal and debris recycling are essential for maintaining a safe and clean environment. Here are three things to keep in mind for debris removal:

1) If hazardous materials like asbestos or lead-based paint were present and removed during the demolition, they need to be disposed of following strict regulations to prevent harm to the environment and public health.

2) Whenever possible, materials that can be recycled or salvaged should be set aside for further processing. Many common building materials, such as metals, wood, concrete, and some plastics, can be recycled or repurposed. Recovering valuable items for reuse can also be considered, such as fixtures, fittings, and architectural elements.

3) Some local authorities may require documentation of proper waste disposal, transportation, and recycling efforts.

Working with a reputable demolition contractor who prioritizes responsible waste management and recycling practices is essential. This ensures compliance with environmental regulations and reflects a commitment to sustainability and reducing the overall environmental impact of the demolition project. Always inquire about the debris removal and disposal practices when hiring a demolition company to ensure they follow proper procedures.
