I. GENERAL

A. Purpose

1. The purpose of this document is to provide a standard defining the structured communications cabling systems to be installed within Stafford County Public School facilities. This design shall be capable of supporting IP telephony, desktop network computers, IP surveillance cameras, audio and video distribution, and other technologies as deemed necessary. It is geared toward leveraging our legacy cabling infrastructure while upgrading to more recent technologies in new installations. The goal is to accomplish this using the most robust technology infrastructure and systematic fashion possible.

2. Within this document, the facilities owner is Stafford County Public Schools, and shall be referred to as such, or as “SCPS”, “the School” or as the “Network Division of ITIS”. Bidding low-voltage installers shall be referred to as “Contractor”.

3. This specification defines quality standards and practices common to all SCPS’s enterprise network cabling upgrades and Greenfield (new) projects.

4. In addition to this cabling standard, individual projects will also have associated documentation such as Requests for Proposals (RFP), facility drawings, project schedules and requirements pertaining to that particular job. Such collateral will be referred to in this document as “Project-specific Documentation”, “Project Documentation”, or simply “Construction Documents”. Any conflict between this general specification and any project-specific documentation shall be brought to the attention of SCPS by the Contractor and must be resolved in writing.

5. It is the responsibility of the installing contractor to evaluate these general recommendations and adapt them effectively to actual projects. Contractor is responsible for identifying and bringing to the attention of SCPS any design directions that may be improved. All such changes shall be approved in writing from Information Technologies.

6. Note that while many portions of this campus specification are addressed to "The Contractor", these requirements apply equally to anyone doing the network cabling and infrastructure work within SCPS, whether those persons are outside contractors or persons directly employed by Information Technologies.

B. Scope of Work - Typical

1. Contractor shall be solely responsible for all parts, labor, testing, documentation and all other processes and physical apparatus necessary to turn over the completed cabling system and associated infrastructure fully warranted and operational for acceptance by SCPS.

2. This specification includes structured cabling design considerations, product specifications and installation guidelines for low-voltage network systems and associated infrastructure

3. In addition to systems specifications, this document also addresses applicable codes and standards, contractor qualifications and requirements, system warranties and system testing and acceptance.
