Portrait of an ironworker

Standing nearly 30 stories above downtown Pittsburgh, Al Williams — a third-generation ironworker with 36 years of experience — is in his element.

The 54-year-old has logged roughly 70,000 hours working on countless structures around Pittsburgh. That’s included  PPG Place, Consol Energy Center and the Liberty Bridge. Now he’s working on the newest addition to Pittsburgh’s skyline, the Tower at PNC Plaza.
