The good: Above-average compensation in a lot of positions, really good benefits, decent vacation, modern office spaces. The people are a key strength.
The bad: Advancement opportunities are limited to a chosen few and the culture is deadly and soul-sucking, particularly to women looking for a progressive environment. Women in all areas have left and continue to leave due to the new boys' club being installed at all levels.
Men also experience a demeaning and harassing environment where supervisors and managers take credit and do their best to make others look bad so they look better. It really doesn't matter much what area you work in. If someone senior to you wants your responsibilities, they will take what they like and won't be hindered. If your job is changed, it likely won't be communicated until you find out from someone who is not your direct supervisor or through a job posting that you happen upon.
It might be a good foot in the door in the construction industry. It might have enough good people that you can overlook the corporate culture, but I would not recommend trying it. There are other options out there.
If you're a handsome, young, male engineer who didn't do particularly well in school but likes to golf and drink beers with the boys without having to worry about silly little things like equality, this may be the place for you. And if you do it well enough, you'll move up the ranks quickly.
