How does the tool handle waste?

The `calculate_volume` tool includes a waste factor parameter, allowing you to add a safety margin (typically 5-10%) to the theoretical volume to account for spillage or uneven surfaces.

Can I calculate materials for on-site mixing?

Yes, by using `estimate_materials` with the 'bagged' delivery method or by reviewing the raw material weights (cement, sand, gravel, water) provided in the output.

What foundation types are supported?

The tool supports calculations for slabs, footings, piers, and walls.

This MCP server provides precise, deterministic calculations for all concrete-related structural needs. Use calculate_volume to determine the total volume required for slabs, footings, piers, or walls, including a customizable waste safety margin. Use estimate_materials to calculate the exact number of bags needed for small jobs or the number of truckloads for larger pours, along with the specific weight of cement, sand, gravel, and water for on-site mixing. Finally, use calculate_rebar to determine the total weight and length of steel reinforcement required based on your spacing and bar diameter.
