Fields for project requirements like target strength, slump, and material properties.

In practice, engineers and technicians often rely on spreadsheet software (Microsoft Excel) to perform these calculations. However, standard spreadsheets often lack "depth"—meaning they function as static calculators rather than dynamic simulation tools. A "deep" Excel sheet incorporates logic branching, conditional lookups, and automated moisture adjustments, transforming it from a simple form into an expert system.
