Construction is not really your subject, is it?
Why can't you debate this subject without making smart-arse patronising remarks. Its a real shame because you are obviously a highly intelligent individual with a huge amount to contribute.
I really feel like having a go back, but I won't because I am a gentleman that doesn't have a "superior, I know better than you all" attitude towards anyone that answers back.
However -
No I am not an engineer but I have spent the last 6 years specialising in construction photography, currently working on an several very large coastal defence projects, documenting engineering techniques used to stabilise sand and estuary mud !! Have you actually ever got your feet wet in the mud of numerous UK estuaries and bays ?? I have, as recently as this afternoon in fact.
