1. Identify the Surface Area:
- Determine the surface area that requires formwork. This includes the area of walls, slabs, columns, and other concrete elements. Measure the length, width, and height (thickness) of each component.
2. Calculate the Total Surface Area:
- Sum up the surface areas of all the concrete elements to get the total surface area to be covered with formwork. For walls, use the formula: Total Surface Area=2×(Length + Width)×Height
- For slabs, the total surface area is the product of length and width.
3. Determine the Formwork Area Factor:
- Different formwork materials cover varying surface areas due to joints, overlaps, and connections. Determine the formwork area factor based on the type of formwork material being used.
4. Calculate the Total Formwork Area:
- Multiply the total surface area by the formwork area factor to get the total formwork area required. Total Formwork Area=Total Surface Area×Formwork Area Factor
5. Account for Reusability:
- If the formwork material is reusable, consider the number of times it can be reused for multiple construction cycles. Adjust the total formwork area accordingly.
6. Include Wastage:
- Factor in a wastage percentage to account for cuts, damages, and other potential material losses during the construction process. This helps ensure that you have enough material on-site.
7. Convert to Volume:
- If the formwork quantity is measured in terms of thickness, convert the total formwork area to volume by multiplying it by the thickness of the concrete element. Total Formwork Volume=Total Formwork Area×ThicknessTotal Formwork Volume=Total Formwork Area×Thickness
8. Unit Conversion:
- If required, convert the formwork volume into the appropriate unit of measurement, such as cubic meters or square feet, based on project specifications.
Example:
For a wall with dimensions 4 meters (length) x 3 meters (height) and a thickness of 0.2 meters,
The total surface area would be 2×(4+3)×0.2=2.6 square meters (ignoring openings for simplicity).
If using a formwork area factor of 1.2 for the selected material, the total formwork area required would be 2.6 square meters×1.2=3.12 square meters.
Remember that the specific requirements for each project may vary, and it’s essential to consult with construction professionals and engineers for accurate and project-specific calculations.
