Dear Ridwan,
According to Bluescope structural system.
It seem to be misunderstanding between you and us at the negotiation stage of bidding process.
We understood that PEMB mean to only roof metal sheet excluding the structure of the building.
By the way , The final quotation from CNS cannot cover the PEMB for total building as per your requirement.
Because it's very higher price compare to conventional structure work proposed by CNS in the first quotation.
So please kindly recommend the way to solve this problem so that we can go ahead.
Best Regards,
