Then came the . She divided the mat into a 20x20 virtual grid. For each cell, the spreadsheet summed the moments and vertical loads to calculate the exact soil pressure at that point—no more averaging. If any corner exceeded the bearing capacity, the cell screamed yellow.
Then the table loaded. Column C-7 (the elevator core) showed a ratio of 1.08. "Fail," Maya said. "We need to increase mat thickness from 1.2 meters to 1.35 meters." mat foundation design spreadsheet
"This foundation was designed not just with numbers, but with the understanding that a crack in the ground is a story waiting to be told. Listen to the soil. It will never lie." Then came the
"Problem," Maya said. "The building’s core is offset. We need to extend the mat by 1.2 meters on the north side." If any corner exceeded the bearing capacity, the
Safety factor: 1.25. Code minimum was 1.1. "It won’t float," she said. "But recommend a dewatering system anyway."
She typed in the new dimension. The grid recalculated instantly. All pressures dropped to 148 kPa or less. Green.
