Never seen a load test on a diaphragm wall panel unless you mean a barrette.

What kind of test does your client intend to perform. A vertical load test for a subway station doesn't make sense : vertical loads are not high enough in relation with the area of the bottom of the panels.

For lateral loads, you usually test the ground anchors but not the wall.

I am afraid you are in front of a client without any knowledge of diaphragm walls and/or retaining structures. You would be better off explaining him why he doesn't need what he wants !
