Reinforcement plans are part of the construction drawings (whose target readers are the construction workers, foremen, and site managers), so I would rather expect them at M1:50. There is little of interest for the client; they are more or less layout plans for standardized mats, with information about dimensions and a few individual bars.
Who are you (as a computer scientist I assume: client), and what did you want to discuss about them?
Reinforcing steel is internal stuff, rather unexciting ;-)
