Working on a nice job where I am at the same place, and I really don’t have to answer to anyone. I can just work.
Customer bought the building and now converting it to a production facility. It will have a 2500A 277/480 service when we actually get the gear (April/May). Currently running off a temp 800A 277/480.
Not to be a nit picker, Where is the ground for the transformer? Steel, water, ground/ufer?
Where is the other LV set of conductors?
I have never been a fan of unfused conductors going very far. To many do over jobs after a fault.
Building steel is barely visible below the greenfield connectors in the XFMR side pic.
There are two 200A feeds leaving the XFMR. One goes to a 200A disco, then to a main lug panel. The other goes to the 200A MB 72 Cir panel. It’s not what I would have done, but that’s what was designed.
Ya I caught the two feeds. I agree not what I would have done either.
72 circuits on a 200 amp panel. Ouch!
I always have taken all of the grounds to one place. Inside dry types.
Your lucky to work for someone who buys colored conductors. I never have, lots of phase tape for me.
Curiosity makes me ask, were the shipping bolts on the transformer tight?
I have gotten some Eaton dry types made in Juarez Mx that were,,,, finger tight at best.

The shipping brackets securing the core were tight and a PITA to remove. The bolts to the pallet were tight but the pallet was badly damaged as far as I remember.
I have seen transformers though. that have (left to right) H-3, H-1, H2. Might be one like this. Don't know why it is done that way
