Services/Performance Phases 1-3 according to HOAI/Spatial shaping measures in a condominium

Dear forum community,

We recently purchased a condominium in a historic monument. The purchase was made in an unrestored condition from the owner. The expansion of the residential unit will be carried out by us in cooperation with an architect commissioned by us.
For this purpose, an architect contract based on the HOAI was concluded.

It is a very complex expansion of an attic apartment including the stage above it and a living area of 162 sqm. The estimated construction costs amount to approximately 190,000 euros net.
I have attached the details.
The following services were agreed as "additional services" in the contract – here:

Inventory/measurement: 2,200 euros net (service phases 1-3)
Electrical planning + tendering: 1,800 euros net (service phase 5)
Sanitary planning + tendering: 1,500 euros net (service phase 5)

my 1st question:
Are these services not already covered by the payment for service phases 1 - 5 according to HOAI? Is it allowed to charge a separate surcharge for these?

my 2nd question:
Since it is a historic monument, the bank requires an energy saving regulation concept for granting the Nr. 151 KFW program. The architect cannot provide the energy saving regulation proof himself (in our opinion, however, part of service phase 3 - according to Wikipedia), but the architect did not tell us what costs to expect for this.

Question: is the energy saving regulation proof part of the architect’s fee for service phases 1-9, which in our case is quite generous at approximately 54,000 euros?

Thank you very much for a short feedback.

Best regards

Hello,

..... The energy saving regulation certificate cannot be provided by the architect himself (in our opinion, however, part of service phase 3 - according to Wikipedia) but the architect did not tell us what costs are to be expected for this.
...

Wikipedia is not exactly a reliable source of information, as it is not checked seriously :confused:

Your attachment is too small and therefore not readable.

Rhenish greetings

Hello construction expert,

thank you for your note regarding the attachment. Unfortunately, I don't know how to make the calculation bigger. I made the calculation with HOAI-Online.de. Basically, it was only meant as a supplement. I had already mentioned all the facts in the text.
I am basically aware that WIKIPEDIA does not always provide reliable results, but the sections described there sounded plausible to me.
I definitely do not consider 54,000 euros as a fee for such a measure to be stingily calculated.
Are you familiar with the individual LPs and their content?

Best regards
