To find the actual pressure on the soil, we must include the self-weight of the concrete pad.
Vtotal=V+Wpad=800+907.5=1707.5 kNcap V sub t o t a l end-sub equals cap V plus cap W sub p a d end-sub equals 800 plus 907.5 equals 1707.5 kN Step 3: Check Overturning and Eccentricity

Below are highly recommended technical documentation references, engineering communities, and search terms to locate live, downloadable calculation templates:
Minimum reinforcement should not be less than 0.15% of the concrete cross-sectional area (e.g., 2025 mm²/m for a 1350 mm slab). Therefore, provide at least the minimum reinforcement, often as a top and bottom mesh. To find the actual pressure on the soil,
e=3500+(120×1.5)2150=36802150=1.71 me equals the fraction with numerator 3500 plus open paren 120 cross 1.5 close paren and denominator 2150 end-fraction equals 3680 over 2150 end-fraction equals 1.71 m
Before a single cubic meter of concrete is poured, the designer requires the "Load Data Sheet" from the crane manufacturer. This document provides the specific loads acting at the base of the crane tower (flange level). e=3500+(120×1

A tower crane foundation must safely transfer massive vertical, horizontal, and overturning loads to the ground. Engineering this structure requires meticulous compliance with structural codes like ACI 318 or Eurocode 2.
