Respected Sir, Natural ground having Black Cotton Soil up to 5'6" depth then clayey soil. Tie beam is to placed above ground level. Since road level is 1"0" higher than NGL. Is SSM work is necessary to proviod below plinth beam. Excavated soil filled with moo rum and well compacted.
Column size : 15" * 9" . Beam size : 15" * 9" . | | |

In my opinion when you are giving the load of walls to plinth beam and that may be transferred to columns and than foundation, so no SSM work is required. Take opinion or follow the instructions of your structural designer.
see below
- SSM- SIZE STONE MASONARY0 The SSM is a substructure is the lower
portion of the building, which transmits the load of the superstructure
to the subsoil0 SSM distributes the loads of the super structure, to a
larger area so that intensity of load at its base does not exceed the
SBC of the subsoil
-
14.
0 SSM provide levelled and hard surface over which super structure can
be built0 The stability of the building ,against sliding and overturning
,due to horizontal forces such as wind earthquake etc. Is increased due
to SSM0 The ratio of cement mortar is 1:6 i.e., 1 part of cement and 6
parts of fine aggregates(sand)0
