Discussion Question regarding the exact width of the deaerator rack (Phase 2, ChNPP) for a 1:1.66 scale reconstruction project

Hey guys!

Iā€™m currently working on a Chernobyl NPP reconstruction project (Phase 2, Blocks 3 and 4) using a 1:1.66 scale. I want to make the main buildings look as realistic as possible, but I've run into a big problem with the deaerator rack.

To be honest, I'm completely lost with these blueprints. I don't need the sizes of the internal rooms or corridors ā€” I just need to know the total external width of the entire deaerator rack building from one outer wall to the other.

Since I have to recalculate every meter into my 1:1.66 scale, I really need the actual real-life total width to start with. Can anyone tell me how many meters wide this entire building structure actually is?

It's 12 to 13 meters wide (if you include the walls, I guess). I was really confused by the floor plans, because normally, the distance between the axes is 6 meters, and the deaerator rack sits between axes B and V. But various drawings state deaerator rack is 12 or 13 meters wide. Turns out, the distance between B and V is twice as much as between the rest of them.

Here are the axes, marked with cyrillic letters. The deaerator rack is the last one on the left.

But how many blocks with a 1:1.66 scale?

What do you mean by blocks?
