You are correct but you need to call them and they will give the dimensions.

Normal pads for 75 to500KVA is 84" x 78". 9 or 10 inches thick.
Seems that coming from the left it's 2 foot in from the edge of the pad, 1 foot back from the front.
Check specs to see if large sweeps are required, and if they are metal vs PVC.
Call might not hurt.
I need to call the utility, however, what is common practice for laying out pipes in a transformer pad?......What I remember is primary on left and second on the right, looking at the pad from the front...
All the material is being supplied by the POCO and is already sitting at the job...All I have to do is glue it all together...
