An 11-story office tower in Dallas, Texas was set to be brought down in a controlled demolition on Feb. 16, but while implosion dropped the outer shell of the building, it failed to bring down the structure's concrete core.
Almost two weeks later the slightly tilted core remains standing, and work continues on bringing it down. The demolition contractor, Dallas-based Lloyd D. Nabors Demolition, has said that it has a multistep plan in place to bring the rest of the building down using a combination of an wrecking ball on a crane to demolish the upper structure and a high-reach excavator to knock down the rest of the core.
