Working
  1. Total = 40.00 × 30.00 × 0.200 m = 240.0 m³ → at most 60.0 m³ per pour → 2 × 2 bays
  2. Checkerboard: bays where column + row is even go first, so no two fresh bays touch; the infill set starts 3 days after the last first-set pour
  3. Bays are labelled by column letter (A, B, …) along the length and row number across the width
