I haven't been to a ton of Industry events that are more geared towards Construction Technology but the few that I have been to were great for networking and learning new ways to use the Contech tools we already had. Bluebeam Xcon is always a good time and you can learn a ton from basic functions to how people are putting code into their PDFs to help them work smarter. I can't wait to attend and finally check out the AGC IT Conference later this year.
The biggest thing about events to me is the networking and learning from your industry peers. There is nothing better than geeking out over ideas and processes with someone else who is passionate about what they do.
