PART 3 - EXECUTION
3.1 Provide factory bends for all elbows on conduit. Do not install more than two (2) 90 degree bends without installing a pullbox. For conduit runs longer than 100'-0", install a pullbox. Where routing is above an accessible ceiling, conduit may be stubbed out from the wall box and turned horizontal above the ceiling and terminated with plastic bushing to protect emerging cable.
3.2 Contractor shall guarantee labor and materials for one year from date of acceptance.
3.3 No LB condulets shall be allowed.
3.4 If pull boxes are installed, they must be large enough to maintain a minimum bending radius for cables.
3.5 A complete set of "contractor revised" drawings of installation shall be provided upon completion of project.
3.6 Backboxes shall be mounted at 18 inches above the finished floor unless noted otherwise on the drawings.
3.7 Category 6 cables shall be wired, terminated and tested to TIA/EIA 568 specifications.
3.8 All computer cables must be labeled at both ends with "Building No." - " Room No." -

"No. of Outlet". If room has more than one outlet, outlets shall be numbered sequentially when going around the room clockwise from the main entrance to the room.
Coordinate cabling identification with Owner's representative.
3.9 All Category 6 wiring, connectors, and jacks must be installed by contractors who are certified installers such that the completed wiring is certified for 15 year warranty for Category 6 compliance. All cabling installed shall comply with TIA/EIA-568 Standards.
3.10 All horizontal cable runs from wiring closet to outlet locations shall be supported with J-hooks recommended for use with Category 6 cables. Bridle rings and tie wraps are prohibited. J-hook fasteners shall be placed at 5 foot intervals and supported from the building structure. Cables shall not be supported on ceiling support wires. Cables shall not be tightly bundled and shall have visible sag between supports. Supports shall have not sharp edges.
3.11 Installer shall maintain the minimum distance from sources of electromagnetic interference: 6 inches from power circuits; 1 foot from fluorescent and HID lamps; and 4 feet from transformers, meters and variable frequency drives.
3.12 Each cable run shall be tested from patch panel to workstation outlets in accordance with TIA/EIA TSB67, transmission performance specifications for field testing of unshielded twisted-pair cabling systems, including attenuation, near end crosstalk, wire mapping, and cable length.
