1. Removable Lower Service Floor for the Scibar & EC Support Structures Edward Chi May 25, 2006 Fermilab/PPD/MD

2. View of the movable lower service fl. For Scibar fiber instal. Steel grating floor module: Can be 24”, 18” or 12” width with (~131#, 88#, or 66# wt. respectively) (alum. Grating fl. will be lighter, but the price will be more expensive and thicker)

3. Instl. the angle beam(2) to the designated location Instl. 64 Scibar module layers first, Then…

4. Install the pre-cutted floor grating modules to the top of the support angle beam, leave ~2’, or 3’ gap for service access, the gap can be re-arranged along x dir. per service requirement. All floor modules and the supt. beams can be removed after the task.
