[Corey, Greg, Hugh, Jeff G.]

After Scott & Dave did some surveying of the Support Tubes of BSC7 this week, we were happy with the Support Tube elevation and ready to start installation work for HEPI.  Today, we:

• Installed Dial Indicators on the ends of the Support Tubes (they reference off the "Accelerometer Plates" bolted on ends of Support Tubes). 
• Installed Support Brackets on each Pier (and eventually bolted to the Crossbeams)
• Removed the iLIGO Coarse Actuation stack on the NE Pier.  We also made marks on the top of the Pier so we can drill some holes in it for the upcoming HEPI installation. 

On Monday, we will drill holes on the NE Pier, install NE HEPI Assy, and then repeat this process for the other three HEPI locations.
