Construction calculations for a 13 meter tall wooden structure

I'm the project manager for the construction of a 13 meter tall treehouse hotel in Sweden. Building permission has been approved. However, in order to commence construction I need some help. Based on the blueprints, I need someone to calculate which wind and snow loads the structure can sustain. Some additional calculations will have to be done as well that I will brief you on if you express an interest to be a part of this project.
