Off Shore CAT "A" is 616 USD. You will have to take a number and wait for someone to quit or die to move up. SAR is not entitled to this despite what they may tell you. If your offer letter says "CAT A" look closely and you may find a hook, line and sinker attached.
New housing is nice (w/ Paki engineering
)but it is near OMAA so you will want a car/transportation. (Khalifa City is a big construction zone in the middle of nowhere) The labor camp is still opened. Probably won't last long as the Zayad Mosque is nearing completion. I wouldn't live there but it is a piece of aviation history in all its 3rd World glory. More importantly it is closer to civilization.
Off-Shore work seems stable and consistant but I wasn't on that side of ops.
