load bearing walls ?

[Robert D.]

i would like to remove couple of walls to open up the kitchen. wall A, wall B and small wall C. it is a trilevel house. i attach couple of pictures. would you know if those walls are for sure load bearing etc ? i hired a structural engineer and ordered a report but I would also appreciate comments from someone who knows framing. I will share the report once  I get it.

I second @Erik B.. Judging load bearing from photos on an online forum is the worst and can lead to disaster if you do not know what you are doing. Get a local architect or engineer to assess. They can determine load bearing walls and also design a support beam if necessary.  

Also, with all the demo done, why are the ceiling still intact? It would be a much clearer picture if you brought these down, at least in the areas where you proposed to remove walls. These areas will need to come down anyway with the wall and possible support work. (I suspect this may be due to the insulation in attic. As others mentioned, this should be tested for asbestos and then removed.)   @Robert D.
