The implosion consultant observed notable differences between the structure as built and one set of 1979 building plans provided by Surfside, Fla., officials.

Search and rescue operations ceased on July 3 so that crews could prepare to raze, using charges, the damaged wing of the partially collapsed Champlain Towers South condominium.

It took 1,900 pounds of explosives and less than five seconds on Feb. 17 to implode the 39-story main tower of the former Trump Plaza hotel and casino on the boardwalk.

An 11-story office tower in Dallas, Texas was set to be brought down in a controlled demolition in Feb. 16, which dropped the outer shell of the building but failed to bring down the structure’s concrete core. 

After delays that threatened to push the project into 2021, the City of New Orleans announced on Jan. 17 that the partially collapsed structure of the unfinished, 18-story Hard Rock Hotel will be brought down in a controlled demolition in late March, under a new plan to be submitted by demolition contractor D.H. Griffin Cos.

Controlled implosions brought down the last structural vestiges of a former military docking and supply center in Bayonne, N.J., on Nov. 30, clearing the way for a 1.6-million-sq-ft logistics center.
