Thanks for the reply.
Apologies for the sizing of photos and rotation, I was uploading from a tablet at the time and struggled with uploads.
So the outcome of the meeting with the senior site manager was that as the build is structural he is not concerned with the cosmetic issues. The conversation lasted about 30 minutes and to be honest he was not interested in my concerns. I found the senior site manager rude, unprofessional and did not give the 5 star service that David Wilson advertise.
Since then I have plastered the photos over social media, within 30 minutes I had the Construction Manager contact me asking for further information. Currently awaiting his response.
I think you're correct with regards to apprentices carrying out the work, this seems a common theme across new build sites these days.
Further the correct orientation can be seen, including the internal Caberdek that has been cut through floor levels to pass boards through.
