To enable moving the largest of these pieces into place on the Penthouse level, cold water pipes to the equipment that removes excess humidity from the air will be cut and remain out of use for about 3 to 5 days. This should not be a problem unless we have unseasonably warm weather with heavy rain, in which case humidity in the stacks may rise above tolerable levels. Stack managers have made provision to keep air moving with fans if humidity levels become too high. Lifts of the major pieces of the new air handling unit will be made by crane during Thanksgiving week, once preparations and repair work on the Penthouse level are completed. Asbestos removal in the Penthouse and Basement was completed last month, and all air samples taken had results below regulatory limits.
Electrical work continues and the main light fixtures in the lobby have been installed.
Ceiling tiles cut to accept the light fixtures for the Reading Room have also been installed along with wiring, and the light fixtures themselves will be installed next. Lighting fixtures have also been installed in the office areas. Sprinkler pipes have been installed and tested throughout the offices and reading room areas. Workers have installed the reveal strips for the areas that will be paneled. The panels themselves will be delivered and installed in early December.
