Pros
You can drink in the office.
Cons
The project managers will load you up with more work that you can handle, then they will go to happy hour. If you are going to work in the Denver office electrical team, don't waste you time. You will be fired for no reason and no explanation. I once had the project manager receive a job on a Thursday, he didn't give it to me so he could go snowboarding Friday, then sat on it all weekend without working, then dropped the project in my lap 12:30 and told me it needed to be done by the next day. I was given projects with less than half of the information. Then after I would finish, i would be told it was wrong based on information from the architect that I was never given. If you are good at your job and have a good work ethic, they will over work you.
