Probably some friend ,of a friend ,of a friend and a tasty brown envelope for services rendered... Think what you could do with £400k(Or what the Council could do with £400k),it's a serious amount of money!!
Don't know. It's a specialised job and if involved re-engineering new parts, calibration etc it would be thousands of hours of work for a handful of professionals in the UK with specialist knowledge and specialised machine work. How much is spent on consultants to have management meetings.. it's a lot of money but relative. It's being fixed as part of the guarantee.
