• Shims – Used to level the beam if necessary.

 

Step 2: Plan and Measure

The first step is to assess the area where the load-bearing beam will go. Measure the distance between supports, the length of the wall, and the height of the opening.

Key Measurements:

• Width of the Opening – The beam needs to cover the entire width and carry the load from above.

• Beam Height – It must fit within the available space while offering sufficient support.

• Load Calculations – Determine the weight the beam must support. Consult a structural engineer if needed, especially for multi-story buildings.

Step 3: Temporarily Support the Structure

Before removing the load-bearing wall, you must properly support the upper structure.

Place the Jacks:

Position adjustable jacks or posts under the floor joists or ceiling beams directly above the wall. Ensure they are secure and able to carry the load.

Check Alignment:

Use a level to confirm the temporary supports are evenly placed and stable.

Step 4: Remove the Wall and Prepare the Opening

Once the temporary supports are in place, you can safely remove the wall.

Demolish the Wall:

Use a sledgehammer or circular saw to take down the wall. Carefully remove drywall and cut through studs as needed.

Prepare the Opening:

Clear away debris and framing materials to make room for the new beam.

Step 5: Install the Load-Bearing Beam

This is the critical phase installing the new structural beam.

Position the Beam:

With help from a partner or lifting device, lift and place the beam into position. Ensure it’s properly aligned.

Secure the Beam:

Attach the beam to the support posts using heavy-duty bolts or screws. Ensure it’s anchored at both ends to the foundation or nearby structure.

Shim the Beam:

If necessary, use shims to level the beam. Always double-check alignment with a level at every step.

Step 6: Recheck Alignment and Finish

Once the beam is installed:

Remove Temporary Supports:

Slowly and carefully remove the jacks or supports. Confirm the beam is fully bearing the load.

Reinforce the Beam:

If your project demands it, add extra framing or bracing to provide additional support.

Step 7: Final Inspections and Safety Checks

Inspect the Installation:

Go over your work thoroughly. Check that everything is level, secure, and properly fastened.

Consult a Professional:

If you’re unsure about any part of the process, have a structural engineer or contractor review your work to ensure safety and code compliance.
