Rugged Steel Staircase Construction – What are your thoughts on this?

I stumbled across this steel staircase construction (most probably for an industrial building), and I was intrigued. The massive size of the sections are thought provoking, and the connections look quite interesting.

I will like us to discuss this design and construction by considering the connections, members, details, applicability, and how it could have been improved. Also can you redesign the staircase by assuming a distributed ultimate load of 20 kpa. Assume a floor height of 4m, and verify if the section was overdesigned or not. Thank you as you air your thoughts and design results.
