There was nothing unusual about the lobby and pool area at Champlain Towers South condo, which looked clean and well maintained to a commercial pool contractor who visited the building last Tuesday, just 36 hours before half of the building unexpectedly collapsed. Then, he saw the basement-level garage. “There was standing water all over the parking garage,” the contractor, who asked not to be named, told the Miami Herald. He noted cracking concrete and severely corroded rebar under the pool... While he had worked in the industry for decades and had “gone in some scary places,” he said he was struck by the lack of maintenance in the lower level. The amount of water at Champlain Towers seemed so unusual that the contractor mentioned it to a building staff member, Jose, who was showing him around. “He thought it was waterproofing issues,” the contractor said of the staff member. “I thought to myself, that’s not normal.” He said Jose told him they pumped the pool equipment room so frequently that the building had to replace pump motors every two years, but he never mentioned anything about structural damage or cracks in the concrete above.
