Hot rivets are actually a good job, they are under constant tension from the moment they are formed.
They are also a whole lot softer and have a much lower tensile capacity.
Granted the action of setting the hot rivets completely fills the holes so they work in both shear and tension. but the friction grips will provide a higher order of clamping force. (the rivet would snap long before the TCB were set)
A structural engineer or his manager (from the type of company working on a project like this) would crap themselves at the though of using something with a "vague" structural capacity.
Cheapness doesn't come into it with Network Rail!
No!.Am I the only one who's surprised that someone undertaking a task of these proportions is asking advice on here?
If it's Grade 1 or 2 listed you HAVE to replace like with like
but rivets are as hard or as soft as the steel you make them from, rather like nuts and bolts
