Reference Document No. 30-0001792-01 on April 21, 2015, Siphya construction has agreed to buy formwork Shear wall VARIO 3.3 m from PERI Formwork and Scaffolding (Thailand) Co., Ltd and bring the wall formwork project at the Hyatt Regency. Formwork such that once the concrete was poured, then a deflection was beyond acceptable values. We have consulted with the PERI team concluded that two of the Steel waler add a third one by the PERI has contributed more to complete. Consistent with the fact that the standard specification sheet has provided 3 walers for 3.00 - 3.58 meter height increments as attached.
We therefore strongly advise the PERI consider added the Steel Waler this time without any additional charge.
Best regards,
