Formula
How the calculation works
Enter the length, height and thickness of the wall, with the thickness in inches as designed by your engineer.
Enter the rates per cubic foot for concrete, steel and labour that your contractor or supplier is quoting.
The tool multiplies length, height and thickness in feet for the volume, applies each rate to that volume and adds the three costs for the total.
Common mistakes
- Designing the thickness without an engineer, since a retaining wall carries soil pressure and an under-designed section can fail badly.
- Forgetting the drainage and backfill, because water building up behind the wall is a common cause of collapse and its cost belongs in the budget.
When to use it
- Use it before building a retaining wall on a slope so the earth pressure and the heavy steel demand are budgeted from the start.
- Use it to compare a thicker wall with a thinner reinforced one, since the cheaper section may cut the concrete volume sharply.
Worked example
A wall 30 feet long, 8 feet high and 12 inches thick has a volume of 240 cubic feet, so at 350 Taka concrete, 120 Taka steel and 60 Taka labour per cubic foot the total is 127200 Taka.
Common questions
Does the total include excavation and backfill?
No, it covers only concrete, steel and labour for the wall itself, so add excavation, backfill and drainage separately for a complete site cost.
