Pros
Used to be for the stock... not so much any more! Kiewit Construction, or Peter Kiewit Sons Inc, or Pacific Building District (whatever it is currently called) tends to give stock after a couple of years, just enough to get you encouraged to stick around (the "golden handcuffs"). Also the safety record at Kiewit is top notch. The crews that put work in place are great, planning the work and execution are unbeatable. It is just a matter of turning the good things up and trying to take advantage of the good people that are still there before they get fed up and leave!
Cons
You wife will get fed up with the schedule (long hours, travel, etc.) and cheat on you, taking half of your stock that you had been working so hard for in the first place! There are an incredible number of folks that have been divorced in the years I worked with Kiewit. They spend too much time away from family/ friends and the wives eventually get tired of it. Upper management is a mess. They have folks in senior management positions that are less than worthless. Also Kiewit tends to beat-up its subcontractors to try to squeeze every $ out of their projects.
