1     Scope of work

       These guidelines are to serve as the minimum requirement for all new construction and retrofit work, including all
       materials, equipment, and labor necessary to install, test, and certify structured cabling systems. On new
       construction sites the conduits will be provided by other contractors.

      a. The structured cabling system for this project includes all communications cabling, wire ways, communications
           outlets, terminal blocks, racks, patch cords, cabinets, splitters, surge protectors, and related connectors,
           mounting hardware, identification devices, accessories, and appurtenances for TIA/EIA Cat 5 data cabling
           system and the telephone distributions cabling system where applicable.

      b. On new construction, the rough-in shall provide all conduit paths, outlet boxes, plaster rings, pull strings,
           backboards, grounding conductors and bus-bars, power receptacles, surface raceway and connectors, and
           utility columns as indicated on the construction documents to accommodate the detailed installation. Existing
           schools will require retrofit work with surface raceways in areas where walls cannot be finished. Panduit LD
           series raceways shall be provided.

      c. The design review will be made available to the project site contact, data processing, and any additionally
           needed personnel prior to installation. This group will make up the Design Review Team. Design documents
           will be provided by the contractor with input from the Design Review Team. A joint site survey will be
           scheduled to verify and agree on requirements.

      d. Provide a complete telecommunication system, fully operational, capable of operating at 100 Mbps or better,
           ready for the occupants to use both voice and data outlets as indicated. The installation shall include all
           accessories, devices, and cut-over from the Southern Bell point of demarcation required to provide a complete
           and functioning system. Any materials and devices not specifically mentioned in these specifications or
           indicated on the contract drawings that are required for a finished and operating system installation shall be
           furnished and installed at no additional cost to the owner. The owner shall arrange for the required wide area
           network connections via routers. This cabling system may require outside fiber optic cabling and terminations
           for adjacent school buildings.
