The second inspection was made two months prior to a June 23 failure that sent slabs crashing

China has seven of the 10 tallest buildings in the world that are under construction. Yet China construction practices, even on closely scrutinized iconic supertall buildings, do not always meet U.S. quality and safety standards, said many high-rise construction experts, at a recent conference on tall buildings, organized by the Council on Tall Buildings & Urban Habitat.That is one reason why it is somewhat comforting that China’s building codes are more conservative, agreed the tall-building

After seven days of preparations, the implosion, which went off without a hitch and left adjacent structures undamaged, took only seven seconds. Courtesy of CDI Completed in 1986, the Radio Network House posed a challenge because its concrete structure was heavily reinforced to accommodate seismic loads.
Despite many challenges, Controlled Demolition Inc. successfully led the razing, using explosives, of the 14-story Radio Network House in Christchurch, which was damaged in the 2011 New Zealand earthquake. The Aug. 5 implosion may open the door to other controlled demolitions in New Zealand, says CDI. “The structure did exactly what CDI said it would, in spite of the extraordinarily heavy rebar in the 1986 [structure] that was built to what was already a rigorous seismic code,” says J. Mark Loizeaux, CDI’s president.He adds that dealing with the concrete structure's reinforcing steel, the area's poor soil conditions and the limited
