At 1:24 am, October 25, 1991, Controlled Demolition Incorporated of Phoenix, Maryland, felled the 108000 square foot, Old Orlando City Hall in Orlando, Florida. CDI was contracted by Chapman & Son Inc. of Orlando, Florida, the Prime Demolition Contractor, and the City of Orlando to perform the explosives phase of the project. CDI furnished $20 million insurance to guarantee the safety of the new City Hall, just 4 feet away. Warner Bros. Inc., currently filming the movie "Lethal Weapon 3", contacted the City of Orlando to see if the City Hall implosion could be utilized as the opening "special effects sequence" for the new film. CDI worked directly with special effects crews in carefully designing an intricate delay sequence, which allowed both CDI's explosives and Warner Bros. pyrotechnics to be initiated simultaneously. Through the use of 180 pounds of explosives in concert with 400 special effects charges, the 33 year old building collapsed in less than six seconds. The end result was not only a superb implosion, but a spectacular visual effect for the upcoming film. Lethal Weapon 3 was released in May of 1992.
