Hi Khun Supanya,
Could you please help to response to the queries from D&B below as soon as possible.
Khun Nat,
Regarding your queries no. 2, please note that we would like D&B to construct only 1 mock up room which this room will have a gypsum board ceiling finish (without Acoustic). So the specification of the acoustic ceiling is not applicable for the required mock up room. I understand that the CAD file has shown 2 mock up rooms so please ensure you have referred to the correct mock up room. Thanks.
Regards,
