A template was cut out to match the base holes on the pier and used as a guide for lining up the hole properly. A hammer drill with masonry bits was used to drill the holes. Drilling cement is surprisingly easy, just make sure to wear eye, ear and lung protection from the noise and dust that seems to squirt up in your face when pulling the bit out of the hole!
A straw taped to the hose of the shopvac was used to suck out the dust from the hole and clear it for the bolt to be pounded and then tightened down.
One bolt ended up not quite perpendicular, but with a little effort the pier did drop down right where I wanted it to be! Success!
