in miami, re-evaluation and re-certification of concrete highrises are done prior to the 40-year ‘dead’line (no pun intended), yet despite repairs, a condo building collapsed. in sg, since climate is hotter, wetter, and more humid, it should be a shorter duration at 36.9 years. typically, those flimsy “sun shades” built with concrete and questionable rebar joints are first to crumble with age. the design is flawed and material used and construction techniques unsafe. from 1st world to 3rd world.
