When should I contact PCD to schedule pick up?

[Sterrico]

My car has a build date of week 36. I will be taking delivery at the PCD. BMW is holding training for their employee's from 10/14 till the first week of November on the new X3. I Assume that no PCD's will take place during this training. I won't be able to have my car built and take delivery before the start of the training. Therefore I must take delivery after the training. So my question is when should I contact the PCD to set up taking delivery? Any help would be appreciated.
