Koji, Rana and Steve

The floor preparation continued today. The really messy part of drilling and jack-hammering the concrete were done in controlled manner.

Particle counts peaked at 106K of 0.3 micron and 13 K of 1.0 micron particles/ cfmin at the top of SP table.

Legs were installed with the help of Koji and strongman Rana. Professor Rana was very useful lifting the 85 lbs legs.
