TN series plan does not show pathways/backet cable tray for horizontal cabling. LV: The Client BOD was not intended Q-Attachment-E-508-22-?00_CLIENT_BOD_BID (1) section Telecommunications to be included in the Bid Package.

Basis of Design (see below). Please give location/pathway as per new building pathway requirements.

New Building Pathways

Existing code-compliant pathways will be utilized, supplemented by new pathways as needed, ensuring a maximum cable fill factor not exceeding 40%. Pathways penetrating fire-rated barriers shall be self-sealing UL listed mechanical assemblies that allow re-entry without the need for fire-stop pillows, caulk, putty, etc.

Furthermore, pathways will be routed for convenient access and will be isolated from sources of electromagnetic

26 interference (EMI), including cables with different signal types and voltage levels. Additional requirements include the following items:

. Provide a minimum 12" wide x 4' deep basket-type cable tray system in main corridors and hallways where feasible. The cable tray system shall be rigidly and structurally supported, maintain a reasonably level elevation, properly bonded between sections, and bonded to the nearest Telecommunications

Secondary Bonding Busbar.

. Use supplemental open-top cable supports (e.g., J-hooks) from the cable tray or primary pathway system to work area ouUets where local regulations allow. J-hooks shall be independenUy and structurally supported, spaced at 4' maximum, and not exceed 12" of sag for installed cables.

TN003 shows civil pathway (doted lines) does not indicate if new or existing. Please advise.

TN series plans show A/B fiber backbone do not indicate pathway requirements.
