The architect did the complete planning including the building application and the exemption application. He also provided us with the execution plans. Then we had a small construction company that took over our plot as it was and in the end delivered a shell construction including all earthworks, water supply and drainage, well, etc. This builder constructed according to the execution plans and had questions at two points where the architect then came out and resolved them. The architect took over the complete surveying of the plot including elevation plans because it is a hillside plot... Yes, he did all that. Which stages according to HOAI exactly, I don’t really know... 1-4, I think.
