Formula
How the calculation works
Enter the number of piles, the depth of each in feet and the rate per foot that the piling contractor quotes.
Enter the rig setup or mobilisation charge, which is a fixed cost you pay even if the piling run is short.
The tool multiplies piles, depth and rate for the pile cost, adds the rig setup for the total, and multiplies piles by the pile capacity for the load capacity.
Common mistakes
- Comparing bids on the per-foot rate alone, when the rig setup charge can differ so much between contractors that it flips the total.
- Ignoring the load check, since the cost can look fine while the pile count still falls short of the weight the structure must carry.
When to use it
- Use it before piling starts on a weak-soil site so the rig mob cost and the depth are both worked into the contract sum.
- Use it to check early whether the number of piles you have planned actually carries the building load once the capacities are added up.
Worked example
With 10 piles each 30 feet deep at 900 Taka per foot and a rig setup of 50000 Taka, the pile cost is 270000 Taka, the total is 320000 Taka and the capacity is 400 tons.
Common questions
Is the capacity figure a guaranteed safe load?
No, it is only the sum of the assumed pile capacities, so a geotechnical engineer must confirm the safe load with soil tests and a load test on site.
