Look up the phone call / voicemail between FIGG engineer and FDOT, in which the FIGG engineer describes the cracking and says it isn't a problem and they're proceeding. The engineer was a man.
William "Denny" Pate was the engineer who stamped the drawings. After the incident he says his wife accidentally put his phone through the laundry, so he couldn't provide his texts for evidence. Hmmmmmm.
