The firm was created by Jack Loizeaux who used dynamite to remove tree stumps in the Baltimore, Maryland area, and moved on to using explosives to take down chimneys, overpasses and small buildings in the 1940s.[2] RecordsThe firm has claimed world records for a series of 1998 projects: The June 23 demolition of the 1,201-foot-high Omega Radio Tower in Trelew, Argentina, "the tallest manmade structure ever felled with explosives"; The August 16 implosion of the 17-building Villa Panamericana and Las Orquideas public housing complex in San Juan, Puerto Rico, "the most buildings shot in a single implosion sequence"; and the October 24 project at the J. L. Hudson Department Store in Detroit, Michigan, which at {{convert|439|ft|m}} in height became "the tallest building & the tallest structural steel building ever imploded" and its {{convert|2200000|sqft|m2}} making it "the largest single building ever imploded".[2][3] Select projectsAlfred P. Murrah Building, Oklahoma CityOn May 24, 1995, the firm was responsible for the demolition of the Alfred P. Murrah Federal Building after its bombing on April 19, 1995.[4] The Seattle KingdomeOn March 26, 2000, the firm used 4,450 pounds of dynamite placed in 5,905 carefully sited holes and {{convert|21.6|mi|km}} of detonation cord inserted over a period of four months to take down the 25,000-ton concrete roof of the Kingdome in Seattle, Washington in 16.8 seconds, one day before the 24th birthday of the stadium that had been the home of the Seattle Mariners of Major League Baseball and the Seattle Seahawks of the National Football League. The total cost for the demolition project was $9 million.[5] The firm carefully planned the collapse of the roof to prevent its simultaneous free fall, creating a delay pattern that would break the roof into pieces and setting up 15-foot-high earth berms on the floor of the stadium to absorb the impact of the falling concrete. The demolition of the Kingdome established the record for the largest structure, by volume, ever demolished with explosives. The implosion of the 125,000-ton concrete structure did not cause a single crack in the foundation of the new stadium being built {{convert|90|ft|m}} away.[6] Gettysburg National TowerCDI donated their services without charge to demolish and clear away the controversial Gettysburg National Tower on July 3, 2000 — the 137th anniversary of the final day of the Battle of Gettysburg. The National Park Service, eager to accept CDI's offer and save the $1 million originally set aside for the project, swiftly coordinated efforts to prepare the tower for the requested date. The 2 million pound (900,000 kg) tower was felled by {{convert|12|lb|kg}} of explosives in front of a crowd of 10,000.[7] World Trade Center SiteOn September 22, 2001, eleven days after the 9/11 attacks, a preliminary cleanup plan for the World Trade Center site was delivered by Controlled Demolition, Inc. in which Mark Loizeaux, president of CDI, emphasized the importance of protecting the slurry wall (or "the bathtub") which kept the Hudson River from flooding the WTC's basement.[8] Cape Canaveral Air Force Station Space Launch Complex 40The tower was disassembled during late 2007 and early 2008. Demolition of the Mobile Service Structure (MSS), by means of a controlled explosion, occurred on 2008-04-27.[9] National Geographic Channel: Man Made: Rocket Tower has a full episode on the demolition [10][11] See also
