We regret that we have been receiving conflicting instruction and confirmation from your side that have been very confusing to our designers. First of all you have requested this to be changed. Anyway we will revert back to you.
For our understanding can you please confirm with as-built, what have been built by marking out and highlighting in the drawings which has been constructed? Your understanding and cooperation on this matter is very much appreciated. We require this confirmation before we make any more changes.
