Engineer-Level Foundation Repair Plan

I need a comprehensive, engineer-level repair plan to address cracks that have appeared in the interior walls and ceilings of my single-family home. The pattern of cracking suggests an underlying foundation issue rather than simple drywall movement, so the plan must pinpoint root causes and lay out corrective steps that bring the structure back to full integrity and code compliance.

What I expect from you:
• A brief written diagnosis of why the foundation is stressing the interior partitions.
• Scaled drawings or sketches that illustrate where underpinning, crack stitching, or other structural corrections should go.
• Calculations or rationale (load paths, soil bearing checks, etc.) that justify the chosen solution.
• A phased work sequence specifying materials, curing times, and any temporary shoring.
• Notes for local permit approval—references to the applicable residential code and, if you are licensed, an engineering stamp ready for submission.

Acceptance criteria: the plan must be complete enough for a contractor to price and execute without further structural input, and the local authority should be able to issue a permit based solely on the documents you provide.

Please leverage any mainstream analysis tools you prefer (e.g., STAAD, AutoCAD, Revit, or even hand calculations clearly scanned) and keep the final package clear, concise, and professional.
