PART 3 EXECUTION
3.01 EXAMINATION
A. Examine all pathways prior to installation of all cables.
B. The Engineer or the Owner has the right to make adjustments to the location of any outlet to
a new location within 7 wall-feet of the original location. If the change is made prior to final
cable termination, and prior to any raceway being installed, then the changes shall be a no
cost change to the contract.
3.02 PREPARATION
A. Locate main path for all cables and install J-hooks where cable tray is not provided.
B. Coordinate with other trades to install a clear, straight path down major corridors for the
routing of user cables back to the communications closet.
C. Plan installation of cables along cable ladder of rack system in communications room. All
cable shall be neatly routed in groups of no more than 24 cables.
3.03 INSTALLATION
A. CAT-6 cabling shall be installed according to TIA/EIA 568-B standards, including all updates
and addenda.
1. When installing CAT-6 cables, care shall be taken to avoid crimping or bending the
cable past the manufacturer’s recommended bend radius.
2. During installation, the cables shall not be pulled across the ceiling tiles or the
structure of the building. This may cause damage to the cable jacket.
3. Adhere to all pulling tensions and bend radii during installation. Excessive pulling or
bending can cause the cable to fail tests after installation. Any cable that does not
pass the CAT-6 tests after installation shall be fixed or replaced at the Contractor’s
expense.
4. All cables shall route neatly in the ceiling. Whether they route in cable tray or
5. J-hooks, the cables shall be neat and orderly.
6. There shall be no more than 50 cables in each J-hook. Provide additional J-hooks as
required.
7. Support all cables at a minimum of every 5 feet.
8. Provide a short coil of extra cable where the cable enters the vertical conduit. The coil
shall consist of no less than 1-1/2 feet.
9. Provide enough slack in the backbox to fully remove the faceplate and jack and allow
work to be done on the cable.
10. When installing cables in the communications room, all cable shall route neatly
through the cable tray and cable ladder.
11. When transitioning from the ceiling area to the cable ladder of the rack system, all
cable shall route through conduits or be attached to vertical section of cable ladder.
The Contractor shall provide the conduits shown and any additional conduits or cable
ladder required to neatly transition cables from the ceiling to the rack.
12. Bundle cables in groups of no more than 24 cables as it routes along the cable
ladder.
13. Cables shall route down each side of a rack for termination. Split each panel into 2
sides. The first 12 positions on a panel are on the left, and positions 13 through 24
are on the right. Route the cables for panel positions 1 through 12 down the left cable
ladder and route the cables for positions 13 through 24 down the right cable ladder.
