🔹 COLUMNBASE EXCAVATION TAKEOFF CALCULATOR

✔ Click “SHOW MORE FIELDS” to enter additional excavation details.
✔ Provide the excavation length, width, and depth.
✔ Input the blinding depth, concrete depth, and reinforcement spacing.
✔ Click “CALCULATE TAKEOFF” to get:
✔ Total excavation volume.
✔ Total blinding and concrete volume.
✔ Total reinforcement weight.

🔹 IMPORTED SAND FILLING CALCULATOR

✔ Enter the site’s length and width in meters.
✔ Provide the depth of sand and hardcore filling.
✔ Select the truck capacity (20 or 30 tons).
✔ Click “CALCULATE” to get:
✔ Total sand and hardcore filling volume.
✔ Weight and number of truckloads required.

🔹 SLAB QUANTITY CALCULATOR

✔ Enter the slab length, width, and thickness.
✔ Input the reinforcement spacing and reinforcement bar weight.
✔ Click “CALCULATE” to get:
✔ Concrete volume required.
✔ Formwork area needed.
✔ Perimeter formwork required.
✔ Total reinforcement weight in kilograms.

STEP 3: GENERATING THE BILL OF QUANTITIES (BOQ)

✔ After performing calculations, click “GENERATE BOQ.”
✔ A detailed table with calculated values will be displayed.
✔ Each row allows manual adjustments for flexibility.

STEP 4: DOWNLOADING BOQ IN DIFFERENT FORMATS

✔ Click “DOWNLOAD BOQ AS EXCEL (CSV)” to export the Bill of Quantities as a spreadsheet.
✔ Click “DOWNLOAD BOQ AS PDF” to generate a professional, printable PDF report.

IMPORTANT TIPS FOR ACCURACY

✔ Ensure all input values are correct before clicking “CALCULATE.”
✔ Use meters for dimensions and millimeters for reinforcement sizes.
✔ Verify spacing and bar selection to get the correct reinforcement weight.
✔ Recalculate if any value is changed to update results.
✔ Consult a structural engineer before purchasing materials.

WHY USE THIS CALCULATOR?

✔ SAVES TIME: Eliminates manual calculations and speeds up estimates.
✔ REDUCES ERRORS: Provides accurate construction takeoff estimations.
✔ IMPROVES PROJECT PLANNING: Helps with budgeting and material forecasting.
✔ EXPORTABLE BOQ: Generates a professional Bill of Quantities that can be shared easily.

COMMON QUESTIONS & TROUBLESHOOTING

Q: My calculation result is 0. What should I do?

✔ Double-check that all input fields are filled in correctly and are greater than zero.
✔ Ensure that you are using meters (m) for length, width, and thickness.

Q: How do I modify the BOQ after generating it?

✔ You can manually edit each field in the BOQ table before downloading.

Q: Why is my reinforcement weight not accurate?

✔ Ensure that you selected the correct reinforcement diameter.
✔ Double-check reinforcement spacing for accuracy.

Q: Can I use this calculator for multi-story buildings?

✔ Yes! Simply enter the values for each level separately and sum up the results.
