Munilla noted that the company's project executive, Leonor Flores, is herself an FIU graduate.Two of the biggest firms that built the Florida International University pedestrian bridge that collapsed today have recently been accused of unsafe practices. In one of those cases, another bridge project toppled onto workers.Police and fire-rescue personnel are still on the scene at FIU, where multiple people died in the rubble of the 950-ton bridge, which crumbled onto SW Eighth Street traffic.
