She’d built the spreadsheet over four years—through two jobs, three grad school courses, and one humiliating moment when a senior reviewer found a factor-of-safety error in her first solo design. That mistake taught her to color-code every assumption: blue for input, black for calculation, red for warnings, green for code checks.
By 1:15 AM, she had a complete design: reinforcement spacing, geogrid type (Uniaxial 120 kN/m), facing panel details, granular fill requirements, global stability check (yes, that tab linked to a separate slope stability macro), and a one-page summary for the client. mse wall design spreadsheet
She attached a one-page PDF—auto-exported from the spreadsheet—showing exactly why. She’d built the spreadsheet over four years—through two
At layer 7, the spreadsheet threw a warning: Looked at her
He flipped through. Paused at the seismic tab. Looked at her. “You checked the connection strength against AASHTO Table 11.10.4.2.1?”
She pointed to cell on the printout. “Automated. Also ran a sensitivity analysis on backfill compaction pressure—it’s in the hidden sheet, tab 14.”
She saved the file and hit Out came 22 pages—input summary, calculation steps, code references (AASHTO LRFD 11th Ed.), and a table of factors of safety. All without a single arithmetic error.
