When I lived in South Florida, I was aquantinances with a woman who is a Professional Civil Engineer. She was tough as nails and wouldn't back down, but the amount of times she had to fight for anyone to actual believe that she was the engineer and even more, for people to believe her (even her coworkers) and what she was saying, was absolutely shocking.
My husband works in architecture here and he hasn't come across any female engineers, unfortunately. He also doesn't really know any female building site managers, bar one. And he says that she is ace and so helpful and very well respected. That is a really tough industry and it really needs change.
There's building work going on here and I saw a female builder on site today and I wanted to run over to her and give her a big hug! But she probably would have called the police. HAHAHA.
