[Ming Pao Special News] Hongfuyuan residents complained about foam sealed windows before the fire. Gu Xiaoping, senior building maintenance surveyor of the Independent Review Unit (ICU) of the Housing Bureau, said yesterday that he had been about to overhaul the contractor Hongye and registered inspectors (RI). The other party said that it would "do it on 3 floors", that is, chiseling and removing every 3 floors of the sealed windows, and replacing another 3 floors.
