Precast and cast-in-place box culverts are critical hydraulic structures. While dedicated software exists, spreadsheet-based design (using Microsoft Excel or Google Sheets) remains popular due to transparency, cost-effectiveness, and customization. This paper evaluates the essential features of an effective box culvert design spreadsheet, compares five available download sources, and proposes criteria for “better” download selection based on structural compliance (ACI 318, IRC:15, or BS 5400) and hydraulic conformance (HDS-5).
