Guide — Pile Foundation Capacity
The pile foundation calculator below follows standard Indian construction practice and the relevant IS-code conventions. Enter the site dimensions exactly as measured, press Calculate Now, then refine the quantities line by line in the live sheet before you export.
Ultimate pile capacity is the sum of skin friction along the shaft and end bearing at the toe. In cohesive soils the adhesion factor α is taken as 0.4–0.7 of the undrained cohesion depending on stiffness.
A factor of safety of 2.5 on the ultimate capacity is standard for bored cast-in-situ piles, and the result must always be confirmed by an initial load test to 2.5 times the working load per IS 2911.
Add 3–5% to the theoretical concrete volume for bore overbreak in loose strata, and remember the pile cap, lean concrete and pile cut-off wastage when preparing the BOQ.
Treat every output as an indicative pre-tender estimate. Site conditions, wastage allowances, specification changes and local market rates all move the final figure, so validate against your drawings and approved rate analysis before procurement.

About the Pile Foundation Capacity
This tool is built for site engineers, quantity surveyors, contractors and property investors who need dependable numbers fast. Every input is reactive — changing a single field instantly recomputes the full output set, so you can run sensitivity checks on dimensions, grades and rates before committing to an estimate.
Keep unit consistency in mind: metric inputs (metres, square metres, cubic metres) produce metric outputs, with imperial and Indian trade units shown alongside where they are commonly used on site.
