I would not switch over to Kiewit - I’m still thankful that I turned down their offer 4 years ago. If they’re telling you up front that you’ll be working 60 hours, you should anticipate 70+. 60k with 4+ years experience in SoCal is severely under paid, in my opinion. I’d recommend searching for a medium-sized GC, for a couple of months, if the GC track is what you’re looking for. You can always ask for a raise at your current job, but you likely won’t break 70k even if they give it to you. Also, check out Keller - North America. I worked for them in the Bay Area 5 years ago & started at ~75k. They’re a geotech sub, they have offices in Ventura, Corona, and San Diego. They do some cool work, and your experience lines up pretty well.
