raining heavy here the last few days. So water retention should not be
as bigger problem as one would think.

Personally I think that you should walk away. Topsoil onto concrete spells a recipe for disaster.
Whilst grass or turf depending on where you are will grow even in clay… to get good results laying a lawn properly needs to be done properly. If you friend wants a good result then they need to do their homework, bodges are bodges and that’s the way this one will go.
If you still want to it for them.
Strip off the topsoil and stack it somewhere
Excavate the concrete and skip it
Underneath the concrete you may find sub soil, but it will look very “bleached out” and probably be very compacted and in need of aeration. At this point I would check how well this sub soil, clay… drains off. If it is poor then they may need land drains installing
Assuming the existing topsoil is of a reasonable quality, relay it and add at least another 25mm
Add a quality pre feed
Lay turf
Make sure they understand how to water and when to cut the lawn and it should be OK.
