PURPOSE: The purpose of this Operating Policy/Procedure (OP) is to establish a standard procedure for the approval of cable installation in Texas Tech buildings, tunnels, and other TTU locations, and quality control procedures for such work. Under the provisions of this OP, property drawings will be upgraded to reflect the location of all cables installed at TTU locations.
REVIEW: This OP will be reviewed in February of even-numbered years by the Associate Vice President for Operations in coordination with the Senior Director of Telecommunications and the Director of Communication Services with substantive revisions consolidated by the Associate Vice President for Operations and forwarded to the Senior Vice President for Administration & Finance and Chief Financial Officer.
For the purpose of this OP, cabling is defined as any communication, telephone, fiber optic, security alarm, fire alarm, energy monitoring system, data acquisition, video, audio, two-way radio, or department or school network cables.
a. The Senior Managing Director of Building Maintenance & Construction is responsible for the control of, access to, and use of the utility corridors in TTU buildings and tunnels, and utility rights of way at TTU locations (surface, underground, or overhead). This responsibility includes installation of appliances and cable systems at TTU locations. Therefore, the installation of any wiring or cables at TTU locations must receive approval from the Senior Managing Director of Building Maintenance & Construction.
b. The Information Technology Division is responsible for the installation of all digital, audio, video, or network communications. The installation of any network communications cabling must be initiated in accordance with OP 52.03, Telecommunications Services.
