A drilling jig assembly includes a hub unit that has a receiver and a plurality of spokes and the receiver engages a kelly bar of a drilling rig. A plurality of bolt jigs is each coupled to a respective one of the spokes on the hub unit to receiving a respective one of a plurality of bolts of a bolt cage. A plurality of yoke supports is each slidably disposed on a respective one of the spokes of the hub unit such that each of the yoke supports is spaceable an adjustable distance from the receiver of the hub unit. Each of the yoke supports can be attached to a concrete form surrounding the bolt cage thereby facilitating the concrete form to be maneuvered by the drilling rig when the receiver of the hub unit is attached to the drilling rig.
