Engineering Expo and Recognizing Rebar

Today was a perfect chance to learn about the bridge project, what with plenty of experts at the Engineering Expo ready to answer questions. I bet you were there trying to stump one of them.

Not possible. You’d have learned, however, the main span towers are 1,200 feet apart at each end of the channel, and their platforms are 14 feet thick and more than 360 feet long. It took a lot of concrete — 11,000 cubic yards, to be exact — to fill them. And you’d have learned lots more.

While there I visited several exhibitors and, among other things, learned how sewers are relined using a sophisticated method. What caught my eye was an object on the table that was the same size and shape as something I’ve seen before.

I asked the woman if it was rebar; she said yes, it was, and seemed surprised I recognized it. Between you and me, I wouldn’t know a rebar sample from a hole in the wall had it not been for the educational outreach presentations. Speaking of which, check out photos from today here.

I’d like to know what you think.
