Structural Engineer for Load-Bearing Wall Removal
Removing a load-bearing wall changes how roof and floor loads reach the foundation. We calculate the replacement beam, posts, connections, and supporting footings, then prepare the structural drawings typically needed for a building permit.

Projects this service is built for.
- Open-concept kitchen and great-room remodels
- New openings in exterior or interior bearing walls
- Flush or concealed beam design
- Projects with new point loads over existing framing or foundations
Load-path assessment
We identify what the wall supports and where the replacement loads must go.
Beam and post calculations
We size the beam, posts, connections, and any required footing upgrades.
Structural permit drawings
We show the new opening, member sizes, connections, and construction notes clearly.
From first review to structural plan check.
