The plan frame is 93.7 * 66.2 inches.
This means that the paper size should be at least that big. Huge isn't it ?
Practically, I believe it will be impossible to print on one single sheet. Usually, print shop can print on multiple paper sheets with crop marks. The crop marks will allow you to adjust & glue the sheets together.
Four B1 (ISO) paper sheets or four A0 paper sheet per plan sheet should be enough.
Feel free to shoot more questions ... you don't see my face anyway
