Does this B&B look OK?

How does this look to you?

 

I’m assuming the unevenness in the centre of the floor will be taken out by sand or screed before the membrane then insulation go on, but what about the edge?

 

I’m concerned about building my block wall (inner skin) up off the edge of the of this BB floor because it looks so far off level.  The beam at label A is standing much higher than the blocks either side.  The block from B to C doesn’t look flat.  The top of the left edge of the block at D looks a lot higher than the top of the right edge at E.

 

The beams went onto DPC.  I don’t see that the DPC is doing anything because there’s a dollop of mortar connecting the concrete block in the BB floor to the trench block beneath.

 

I already had a conversation about this picture with somebody & I realised our conversation wasn’t making sense because they were looking at the picture on a phone & they couldn’t see the picture properly, so answers from desktop computer users will be more highly valued, please.

 

I didn’t notice this unevenness until I got the picture off my camera & onto the PC.  So there’s a chance that the imperfection is exaggerated by the stupid modern camera, with its wide angle lens.  I will have a good look at this when I’m on site tomorrow.

@Tony L did you ever get this resolved? I’m no expert and am interested as we’re looking at a B+B floor too - I’d be questioning it exactly the same as you have. 
 

good luck

@Great_scot_selfbuild The problem was only resolved in the sense that we have decided to work around these defects, rather than pull the B&B floor up & get it put down properly.  The builder who created this mess is no longer working for me.  I've had his work inspected by a better builder.  We can take out the uneven edge, pictured above, in the mortar bed.  Some of the other work he did is going to be taken apart & re-done.  I'm very unhappy that he's put the beams onto 350mm trench blocks, rather than onto 100mm wide concrete blocks, forming the inner leaf of a cavity, which is what he was supposed to be doing.  The beams are going to be far more damp prone than they would have been if he'd built according to the drawings.

 

I thought I could trust this builder, as there is a connection to my family.  That was my mistake, & it was a huge one.  There will be a pause in works on site for at least three months now.  When we re-start, with new builders, I'll try to visit the site every day.
