External stability treats the MSE mass as a rigid gravity retaining wall. The spreadsheet must compute the driving forces against the resisting forces to evaluate three primary failure modes:
“No, you don’t,” Marcus said. He turned his screen around.

The story begins with a geotechnical engineer buried under AASHTO LRFD manuals and coffee-stained scratchpads. Designing an MSE wall isn't just one calculation; it’s a grueling cycle of checking stability against overturning, sliding, and bearing capacity .
An effective MSE wall design spreadsheet must incorporate regional design methodologies. Most modern infrastructure projects rely on one of two standards: 1. AASHTO LRFD (Load and Resistance Factor Design) External stability treats the MSE mass as a
