Tool Usage

Return to old version

Set base section size first, then material parameters, then generate quantity and cost results.

Supports single section, multi-section, and CSV batch data. All calculations are done on this page. Batch results preview only the first 20 rows; exports include all records.

Basic dimensions

Choose an input mode first. Single is for quick estimates, multi is for L-shaped, T-shaped, or varied sections, and batch is for table data.

Step 1 / 3

Set the base dimensions first. Input dimensions are converted to meters. Formula: net concrete volume = length × width × height.

Instructions

Software Usage Instructions

Select an input method: In the “Basic Dimensions” step, choose single-section foundation, multi-section foundation, or batch CSV. Use single-section for simple projects; multi-section for different cross-sections or irregular layouts; and batch CSV for tabular data.
Enter foundation dimensions: Fill in the name, length, width, height/depth, unit, and quantity. The tool converts all values to meters and calculates the net volume using “length × width × height”.
Set material parameters: Select the concrete strength grade, and enter the density, reserve margin, and purchase rounding method to calculate the volume including margin, purchase quantity, and concrete weight.
Configure rebar estimation: Enable rebar quantity as needed, and set the main bar diameter, number of bars, stirrup diameter, stirrup spacing, cover, and lap loss.
Configure cost estimation: Enter the concrete unit price, rebar unit price, labor cost, and other cost percentage based on local quotations to generate a cost summary.
Calculate and export: Click “Calculate and View Results” to generate the summary and details. The batch data page previews the first 20 rows; CSV and ZIP exports include all records.
Save settings: Click “Save Dimensions” or “Save Settings” to reuse common parameters next time.

FAQ

A: For a strip foundation with a rectangular cross-section, the net volume is usually calculated as length × width × height. For multi-section foundations, the volume of each section is calculated separately and then summed into the total volume.

A: The reserve margin covers trench deviations, pouring loss, vibration settlement, and similar factors. For standard strip foundations, 5%-10% can be used as a budget reference; increase it appropriately if the trench is irregular.

A: For L-shaped or T-shaped foundations, wall corners, different cross-sections for interior and exterior walls, porch or garage foundations, and similar cases, you can split the foundation into multiple sections. The tool will automatically summarize concrete, rebar, and costs.

A: The rebar results are suitable for budget estimates and material preparation reference. Actual construction should be based on structural design drawings, code requirements, and on-site dimension verification.

A: The recommended format is “Name,Length,Width,Height,Unit,Quantity,Notes”. Supported units include m, cm, mm, ft, and in. You can also download the template and fill it in by column.

A: Actual costs are affected by regional prices, transportation distance, pumping method, labor organization, site conditions, and more. The tool results are suitable as a budget reference, while quotes should be checked against the local market.
