some pride in workmanship in the install, I usually see a bunch of sticks and assort pieces of EMT masquerading as pips holder.
Is this going to have a pad poured over it? is there and grounding method required for the equipment?
would not hurt to bond it

Ground it? or bond it? Typically "isolated" metal parts get a pass, but that may be different if it is service conductors or some other stuff...It will be grounded because it is buried in the ground....

But if they do the min. cover, a "vertical" transition elbow would typically not meet the 18" of cover required by those sections....
