We estimate the dimensions based on a rule of thumb: The foundation weight should be roughly 1.5 to 2 times the vertical load to provide stability. tower crane foundation design calculation example link

Tower cranes are the backbone of high-rise construction. However, a tower crane is only as reliable as the ground it stands on. A catastrophic foundation failure can lead to loss of equipment, project delays, injuries, or fatalities. Unlike standard building foundations, tower crane foundations are subjected to extreme overturning moments, torque, and horizontal forces. Tower cranes are the backbone of high-rise construction
