Dear K. Sakchai , k. Lek, Phongphisit & All,
Originally the 2FL steel structure has been using bolt & nuts joints, not welding-surveyed by ISC & Gamma confirm but ISEC only suggesting but not approved by client/STPN and Gamma.
This is not option cost or additional cost!- as you knew inside factory don’t allow to weld unless got permission/approval-anyway, If ISEC, PPE & Gamma’s others sub-con are not allowed to weld unless approved by STPN & Gamma representative.
