Field notes

The site organizes six calculators around concrete, framing, decking, landscaping, and plumbing, with inputs described in feet, inches, spacing, and waste. Its concrete example converts a 10′ × 10′ × 4″ slab into cubic feet, cubic yards, bag counts, and an estimated cost. The homepage attributes its span and slope tools to IRC 2021 tables and IPC 704.1, while stating that formulas and manufacturer specifications are checked against known examples.
