Below is partly quoted from Business Today's (Issue 945, 2015-02-02, p.80) report on Ruentex's sea-sand buildings:
In summer 2012, Ruentex Development found during a routine inspection that the Ruentex Twin Stars at Tingzhou Rd. and Xinhai Rd. in Taipei spalling concrete and exposed steel bars. The workers suspected corroded steel bars were caused by sea sand containing high chloride ions.
Chairman Samuel Yin convened senior managers and promptly made decisions upon receiving the information. Legally, the structural warranty of 15 years had expired, and there were no inspection standards for sea sand 24 years ago; Ruentex Deveploment thus did not bear any legal responsibility.
Because we wanted residents to have a safe home for a lifetime, Ruentex coordinated property rights and funded the reconstruction. Moreover, per Municipal Regulations for Concrete Buildings with High Chloride Ion in Taipei, the reconstructed apartments are on the same floors with identical orientations and documented areas. Residents never had to fret over safety and funding.
Though doubts and criticism emerged when Ruentex notified homeowners about the sea-sand building evaluation, the Company displayed commitment from day one. Within two months of the first signed contract on 2013-11-04, 60 of the 106 homeowners agreed to the contract. The last one was signed on 2014-12-14 after a year and a month, roughly 400 days of coordination.
