Video above: Florida resident files lawsuit over building neglectContractors began pulling permits to build Champlain Towers South in 1979. In May of 1980, a year and a half before completion, the owner asked for the cancellation of the building permit, giving the reason that the general contractor had resigned. Documents show the same day a new person was put in charge."That's not a good sign," said Surfside Mayor Charles Burkett. Burkett said while the town is pursuing its archives and releasing all documents pertaining to the tragic condo collapse, he had not heard about this and doesn't know why the general contractor resigned."It could be a multitude of things but it's always better when you have the same team that starts, finishes it," Burkett said.Documents also reveal two penthouses that weren't part of the original plans were apparently added by the builder in violation of the town's height limits and that raises questions – did those penthouses put extra stress on the building?"With respect to the penthouse that was allegedly added at the last minute — I think it would be interesting to know whether that last-minute addition was last minute while the plans were being drawn so the structure could be reinforced to support that or whether it was a last-minute addition after the building was built and there was not enough support," said Burkett.In a letter dated Dec. 2, 1980, the town revoked and canceled the tower's permits because the town attorney said in his opinion the penthouses were "a violation of the code of Surfside and that you were so advised prior to the issuance of the permits."A week later the town council voted to give the building a special exemption to allow the penthouses. Documents released Wednesday also show extensive concrete repair work and restoration was done by several companies as far back as 2000 and continuing through 2009.All of this coming under scrutiny as the investigation into this tragic collapse continues."Buildings don't just fall down in America. It's a third world phenomenon, not a first-world phenomenon — something was very very wrong with this building and we're going to find out what happened," Burkett said.
