General
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 AT&T 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.
