Pile Cap Design - 2

The document outlines the design specifications for a pile and pile cap for an 800 cum OHR in Baduria Municipality, detailing load capacities, dimensions, and material grades. Key data includes a total dead load of 16,300 KN, maximum vertical load on columns of 2,371 KN, and a pile diameter of 500 mm with a safe vertical load capacity of 630 KN. The design also accounts for seismic effects, increasing the vertical capacity of the pile by 25%.
