C-Bert - happy to be corrected, but as far as I'm aware they are subbied into T-N. I'm sure they were laying people off from the Bristol office a year ago. If they've taken them back on - fair enough, but I still doubt that they would be doing the detailed design on CADDS5 or FORAN - that tends to be the shipyards involved who have to augment their drawing office staff with contract labour, which is where many of the problems occur.
In any case the original premise is still valid - very little progress on detail design has yet been made and there are still some horrendous aspects of the design that need to be addressed.
