I think the economical option is wrong!
It consumes a huge amount of reinforcement and concrete as well!
So it may be costly!

Grillage foundations consist of a number of layers of beams usually laid at right angles to each other and used to disperse heavy point loads from the superstructure to an acceptable ground bearing pressure.

Mostly there are two types of grillage foundation based on type of material used:

A) Steel grillage foundation.

B) Timber grillage foundation.
