Performance status on architect's invoice?

Good evening,

I need (again) the advice of this great forum.

Our architect, whom we commissioned from the basic evaluation to the object supervision for our house construction, has repeatedly issued invoices during the construction, which we have also paid promptly.

Currently, our construction is at the start of facade construction (outside) and the start of laying the underfloor heating (inside). So already quite advanced, but some essential trades are still missing (e.g. screed, parquet, tiles, painter, carpenter, outdoor facilities, etc.).

We have now received another invoice from the architect and with the payment of this invoice, we have reached 91 percent of the performance status.

Basically, we have no problem paying this. It just seems a bit advanced to us. How would you react to this?

Thank you very much and have a nice evening!

32% of the total fee would be allocated for construction execution according to HOAI.

Estimated start of facade construction = 50% of construction work.

An invoice at 84% instead of 91% would be more appropriate.

Whether it is worth asking the architect about this is up to you to decide.

Thank you very much for the quick and good information !
Have a nice evening!
