RAC Update – 1/17/2007

General

After a thorough study of the existing plaster to ensure that no Madison material would be inadvertently removed, a majority of the post-Madison plaster on the interior wood partition walls is being removed.  Large (2’ x 2’) samples are being taken from each wall where plaster will be removed and all plaster found on interior masonry partitions is being retained.  The plaster is being removed due to cracking that resulted from raising the flooring systems back to their approximate original locations. 

HVAC/MEP 

The roof of the bunker has been poured and the excavation for the entrance is on-going.

Work on the electrical, fire suppression, VESDA, and temperature/humidity monitors continues.  Two of the high-pressure mist lines have also successfully passed their initial pressure tests.
