Foundation Inspection & Structural Engineering
A structural foundation inspection evaluates visible distress, framing and load paths, site context, and available records to determine whether a structural problem is present. When repair or new construction is required, we prepare calculations and drawings matched to the building and available geotechnical information.
Projects this service is built for.
- Cracks, sloping floors, sticking openings, or suspected settlement
- Additions and new buildings that need engineered footings
- Foundation repair design and permit documentation
- Property owners who need an independent structural opinion
On-site structural inspection
We document visible conditions, measurements, load paths, and areas requiring further investigation.
Written findings
We explain what was observed, the structural significance, limitations, and recommended next steps.
Repair or new-foundation design
When needed, we calculate and detail footings, grade beams, underpinning, or related structural work.
From first review to structural plan check.
