Establish wall geometry
Measure wall length and exposed height by segment, including steps in grade.
Curves and corners should be identified because they can change block and cap cuts.
Use actual block dimensions
Course count follows installed block height, while units per course follow installed face length.
Keep the assumption visible so it can be replaced when project or product data is available.
Calculate caps separately
Cap dimensions and overhang can differ from wall units, so cap count needs its own run calculation.
Corners and curves can increase cap cutting.
Separate base and drainage rock
Leveling base and wall rock are volume calculations with project-specific widths and depths.
Do not infer these dimensions from block count alone.
Treat reinforcement as design information
Geogrid length, layers, drainage, embedment, and wall limits depend on site and design conditions.
Use the selected system manual and qualified design where required.
