Should the so-called construction and installation engineering fee included in the engineering design fee include the compilation of annual price difference?

I wonder if the annual compilation price difference mentioned by the landlord is included in that part. If it is included in the collection fee of the budgetary estimate, it should be included. If it is included in the reserve fee, it is not included.

The calculation base of engineering design fees should generally be the sum of all investment and joint commissioning fees except other engineering fees, construction preparation fees and interest.
