Last post was all about the concrete. Now, here's the steel. It is amazing how fast a good crew can throw up a building. I watched the steel delivery and the erection of most of the columns and first floor in the space of a few hours! I also learned a little bit that I surprising didn't know from all my years in engineering. I always wondered about all the miscellanous holes that the beams had--those other than ones for bolts. Now I know that these holes are used to attach safety cables allowing the ironworkers to always be close to a tie off point. It was also super cool to see the guys climb columns to get to the 2nd floor steel. Definitely talented and skilled work.
