Under the SSoCC you calculate the People rate and then apply the percentage for people overheads stated in the Contract Data. Equipment costs are calculated in accordance with component 2 and then you apply the direct fee percentage to both of these.
Under NEC3, if you have any subcontract costs then these are also allocated to the appropriate components of the SSoCC in the same way, although they are treated differently under NEC4.
From your question it is not clear why the 'fee on fee' query has been raised.
