The engineering map below outlines the precise boundary coordinates of the Neutral Axis and associated zero-pressure uplift regions.

5. Compliance Summary & Professional Validation Sign-Off

• The internal calculation engine checks soil-structure lift-off for all five biaxial loading cases.
• Peak edge bearing pressure p_max must remain within allowable SBC limits.
• Reinforcement enhancement is required if uplift or severe stress concentration develops.

6. Stability & Geotechnical Validation
