The Basic is competitive for the job mentioned. Let me sum it up for you, find below the expectations in O&G.
Basic 16K (depends but in your case sounds competitive to me)
Housing 15K
Transport 2K (not including interest-free car loans, but not up to 100 per cent)
Schooling up to 33K per child per annum (fees & textbooks only)
Furniture 45k once off, 6k per annum after 4th year

So you have to ask these questions since you're not getting most of the above.
Accomodation type. Number of rooms, locality, maintenance, Electricity & Water etc
School type, entitlement, fees, text books, uniforms, extra co-curricular expenses. If they gonna pay up for Doha College everything inclusive, then you're fine.
Transportation provision - type, maintenance, fuel, children's buses or driven or self-driven
End of service benefit or severance package etc etc
Performance benefit???
Social incentives??? Club memberships???
