LVL beams offer several advantages over traditional wood and steel beams in various construction applications, such as:
Advantages of LVL Beams Over Wood Beams:
Strength and Consistency:
LVL beams offer predictable and uniform performance, minimizing the natural variability found in solid wood beams.
Dimensional Stability:
LVL is less prone to warping, twisting, or shrinking than timber beams. This stability contributes to long-term structural integrity.
More Sizes:
LVL beams can be manufactured to custom sizes and lengths, offering versatility in design and accommodating a wide range of construction needs.
Reduced Defects:
The manufacturing process of LVL allows for the removal of defects and weak points, resulting in a product with fewer imperfections than natural wood. Timber beams might have knots, rot, or cracks that could become a problem over time, which LVL is less likely to experience.
Lighter Weight:
LVL is lighter than equivalent solid wood beams, simplifying handling and installation.
Cost-Effective:
LVL beams are often more cost-effective than large, high-grade solid wood beams. The cost savings can make LVL an attractive option in many construction projects.
Eco-Friendly:
LVL is typically made from fast-growing and sustainably harvested wood species, making it an environmentally friendly option compared to beams made from slower-growing or less sustainable wood. Trees to make LVL can be harvested in as little as 20 years, while a large timber beam would need to come from a tree of 100 years or more.
Advantages of LVL Beams over Steel Beams:
Lower-Weight:
LVL beams are lighter than steel beams, making transportation, placement, and adjustment easier.
Corrosion Resistance:
LVL is not susceptible to rust, a common concern with steel beams in environments with high moisture or chemical exposure. However, LVL should still be protected from moisture and the elements.
Thermal Insulation:
Wood, including LVL, has natural thermal insulation properties. LVL beams can provide better insulation than steel, contributing to energy efficiency and lowering operating costs.
Ease of Modification:
LVL beams can be modified with common wood-cutting tools like saws, drills, and routers, while steel needs specialized tools like welders, grinders, and nail guns.
Aesthetic Appeal:
LVL beams can provide a warmer and more natural aesthetic compared to the industrial look of steel. This is a consideration in projects where appearance is critical.
Load-Bearing Wall Demolition & Replacement Process
Removing a load-bearing wall is a complex task that requires careful planning and execution to ensure the structural integrity of the building. When performed correctly, your space can be opened up, and you can realize your remodelling dreams. If not, the results can be disastrous, including building collapse and injury.
Ottawa Structural Demolition has performed load-bearing wall removal in hundreds of structures around the city. We’ve created this guide to our process so you can know what to expect if you want to demolish and replace a load-bearing wall.
Structural Assessment:
Our engineering team conducts a structural assessment to determine if the wall is load-bearing. Most exterior walls are load-bearing, while only some interior walls bear loads.
Only a qualified engineer can determine if a wall is load-bearing. Never rely on a guess or a how-to tutorial from the internet; the consequences can be disastrous.
Apply For & Receive Permits:
Ottawa Structural Demolition has contacts with the city building department, making the permitting process simple. We’ll submit the plans for work and get them approved within a few weeks.
There are small fees for the permits and inspections that are included in our load-bearing wall removal quote. Working with us takes the guesswork out of the process!
Install Temporary Supports:
The load must be supported while we remove the old wall and install the permanent support system. The temporary supports will be created with adjustable shoring posts or jacks.
This allows us to work safely and raise the ceiling slightly to accommodate the new beam or supports. Installing the temporary supports takes one to two days.
Work Area Preparation:
We’ll clear the area around the wall, moving furniture, belongings, and other obstacles to create a safe and spacious work environment. If you want to preserve your floors, we’ll cover them with protective materials, keeping them pristine.
Electrical and Plumbing Considerations:
If the load-bearing wall contains electrical wiring, plumbing, or other utilities, we’ll call in professionals to reroute or relocate these services before demolition. Electrical and plumbing work can only be performed by licensed plumbers and electricians.
Ottawa Structural Demolition has relationships with trusted tradespeople who perform excellent, efficient work. If your wall needs these services, expect to add a few days to your project length.
Cut Openings:
We’ll use our specialized tools and methods to create openings in the load-bearing wall and make space for the new support structure. This step is typically done incrementally, taking precautions to maintain stability and safety.
Even while being extremely careful, this process only takes about one day, depending on the wall size. There could be noise, dust and debris in the area, and bystanders should steer clear.
Wall Demolition:
We’ll begin the demolition of the load-bearing wall. This may involve using saws, hammers, or other tools to remove wall coverings, framing, and other materials.
Our expert team ensures the demolition area is contained and doesn’t affect the rest of the structure. It’s a delicate process, but you’re in good hands with Ottawa Structural Demolition.
Install New Support Structure:
Install the permanent support structure to bear the load previously carried by the removed wall. This may involve the installation of load-bearing beams, columns, or other support elements.
Ottawa Structural Demolition precisely follows the engineering specifications to ensure a long-lasting, safe replacement. Our team expertly reads and interprets all blueprints while maintaining a safe working environment.
Connection and Fastening:
Securely connect and fasten the new support elements to the existing structure. This may involve bolting, welding, or other appropriate methods per the engineer’s design.
Remove Temporary Supports:
Once the new support structure is secured, we carefully remove the temporary supports. This step happens incrementally to ensure stability.
Structural Inspection:
We’ll conduct a structural inspection assisted by a structural engineer, verifying that the new supports meet design specifications and safety standards. If there are no problems, this step is brief, and we can move on.
Additional Structural Work:
Depending on the design, additional structural work may be required, such as installing hangers, straps, or other components to enhance stability. This step isn’t always necessary.
Finishing Work:
Complete any required finishes, such as drywall, trim, and paint, to restore the aesthetics of the modified space. This is the step where you add your design style and start seeing the space come to life.
Final Inspection:
The local building inspector will visit to ensure the structural modifications comply with Ottawa codes and regulations. If there are any problems, they’ll let us know and give us a chance to make corrections.
Important Considerations:
- Safety First: Ensure the safety of workers and occupants throughout the process.
- Professional Guidance: Consult with structural engineers and other professionals to guide the process and ensure compliance with regulations.
- Local Codes: Adhere to local building codes and regulations at all times.
- Potential Hazards: Be aware of potential hazards, such as electrical wiring, plumbing, or asbestos-containing materials in the wall.
It’s crucial to emphasize that removing a load-bearing wall is a task that should be undertaken by experienced professionals, including structural engineers and skilled contractors, to ensure the safety and structural integrity of the building. Always consult with local authorities and professionals before initiating such a project.
