Responsibilities of the Architect in Tendering

Hello! I concluded a project contract with a GmbH, so not a classic architect contract. Within this project contract, an architect was granted a sub-power of attorney.

Someone is probably trying to limit their liability... which is quite complicated when it comes to real estate. How did you come across the GmbH? Have you asked the references mentioned how they dealt with it? My personal opinion about such constructs I will refrain from...
