Thank you for your e-mail.
Although our staff Guan has discussed with Khun Suriyan already,
We can not find the DWG for Air Shaft.
So that we have now way to quote it…
Sorry but I heard that Guan already informed to Mr. Suriyan.
Did TSUBACO submit their quotation already ???
I guess that now only they can check the DWG for the Air Shaft.
Thanks and best regards,
