A good size building (multifamily) with a service at one end and a feeder to the other end that serves half the building. The distance is 400 feet so voltage drop could be significant.
What amperage to use? Calculated load results in a significant voltage drop. On the other hand the utility is supplying a transformer that is about 20% of the calculated load for the entire building so over sizing the feeder based on the calculated load seems very pointless.
