Ground slab structural load annotation on our frame design

[MikeSharp01]

Can't get hold of our SE so thought I would ask here. On our structural drawings the SE has annotated the loads on our slab using the form, for instance, of 10/5 kN/m for wall runs and just plain 38.6/20.6 for point loads. I had assumed, perhaps wrongly but dimly recall this might be right, that the first number was the dead load and the second was the live (imposed) load. However looking around on the WWW there seems to be no definitive answer and a possibility that the first is the gravity load and the second is the lateral load. Anybody know what is what here? Not sure why I even want to know I guess the slab designer will understand it but I don't like to pass on things I am not clear about myself.

 

In places the numbers are eye watering 38 kN (Dead) + 20.6 kN (Live) [If I have it right] on a 135 x 135 C24 Column - column must be up to it I guess - just feels wrong.

38kn is only around 3.8 tonnes load.

Yes, but when you add the 20kN (Live) and then imagine 6 big bags of ballast teetering on a 3m post 160mm square it just feels wrong!
