A reporter is concerned that not enough thought is being given to structural redundancy and buildability for bridges. They think that buildability should now be automatic and a legal requirement under CDM Regulations. The need for structural redundancy is so obvious, especially regarding crucial small components that it is (nearly) a surprise it has to be done over again.
Especially considering recent bolt connection failures and gusset plates. They say it is a shame if the issues (apparently) became concentrated around price. The two envelope system comes to mind, wherein technical excellence and price are considered separately - without the first, the second should not come into it, cheapest or otherwise.
