(Bubba, Corey, Scott)

[this work occurred on Tuesday 2/8/11]

After the HAM12 anchors were installed the HAM Pier Grout Plates were installed, and then the HEPI Piers were placed on the Grout Plates.  The top of the Pier's elevation was set with respect to the bottom of the HAM E-nozzles.  The distance from the bottom of the E-nozzle down to the top of the HEPI Pier is 4.557" (115.75mm).  The individual level was within 0.004" and between Piers we aimed to get within 0.010".

The Piers were torqued to 125 ft-lbs.
