(g)    Proposed installation schedule;

(h)    Name and telephone number of individual(s) responsible for the installation; and

(i)    Certified approval by the department director, chairperson, or individual of equivalent responsibility level.

(2)    The Managing Director of Building Maintenance and Construction will process the CR in the same manner as a self-help project (see OP 61.35).

(3)    The Managing Director of Building Maintenance and Construction and the Building Maintenance and Construction Work Control Center personnel will review the CR to verify that it does not interfere with any known projects or utilities. If it does not, the Managing Director of Building Maintenance and Construction will forward it to the affected superintendent(s) for technical review.

(4)    The affected superintendent(s) will review the CR to verify that the route indicated is appropriate and does not create interference of any kind for existing cables or utility systems. Finally, an inspection of the area proposed for penetration of the floors, walls, and ceilings will be conducted to verify that such penetration will not endanger existing systems. After this review, the affected superintendent(s) will return the CR with comments to the Managing Director of Building Maintenance and Construction.

(5)    The Managing Director of Building Maintenance and Construction will consider the comments received from the affected superintendent(s) and approve the installation, or prepare comments to the requesting department indicating disapproval and the reasons for disapproval. For projects that are approved, written authorization to proceed will be forwarded to the requester, along with any special instructions and appropriate guidance on standards of installation as prescribed in this OP.

(6)    The installing department will notify the Managing Director of Building Maintenance and Construction of the estimated start date and the estimated completion date of the installation.

(7)    The affected superintendent(s) may make periodic inspections while the cables are being installed, and will inspect the installation after it has been completed. Any deficiencies or improper installation will be reported to the Managing Director of Building Maintenance and Construction and to the installing department for correction.

(8)    After all deficiencies have been corrected, the affected superintendent(s) will make a final inspection of the installation and recommend approval to the Managing Director of Building Maintenance and Construction, as appropriate.

(9)    The Managing Director of Building Maintenance and Construction will notify the installing department of the approval and request a final drawing of the installation be submitted to Managing Director of Building Maintenance and Construction for inclusion in campus building plans.

c.    Identification system used on replacement cables.

4.  Standards of Installation

All cable installations on the Texas Tech campus will meet the specifications and requirements established by Uniform Building Code (UBC), National Safety Code (NSC), National Electric Codes (NEC), The Institute of Electrical and Electronic Engineers (IEEE), Electronic Industries Association (EIA), and American National Standards Institute (ANSI). In addition, all installations will comply with established federal and state regulations concerning the disturbance of asbestos-containing materials. Specific standards established for the installation of cables at TTU are as follows:

a.    All wall, ceiling, and floor penetrations will be made in accordance with applicable codes and standards noted in Section 4 and, specifically, in Sections 709, 710, and 711 of the 1997 UBC.

b.    All cables in plenums shall be in conduit or have an outer jacket approved for use in air plenums (e.g., "plenum-rated").

c.    Cables will be laid in existing cable trays and bundled with wire ties every 20 feet. In areas that do not have a cable tray, alternate means of support may be acceptable and, generally, consist of wall locks, clamps, or messenger cable systems. Distance between support points will not exceed eight feet. Cables will not be laid on the ceiling tile or grids.

d.    Cables will not be secured to existing electrical power cables by wire ties or any other method.

e.    Cables will be neatly bundled, and installed and well secured with installation as close to the structural ceiling as possible.

f.    Cables will not be installed in or through any elevator shaft or elevator equipment room unless the cables are specifically part of the elevator system.

g.    Cables will not be installed or passed through any fire dampers.

h.    Cables will not be secured to pipes (water, chilled water, or steam) or valves, and will not be wrapped or entwined around pipes. Cables will not be wrapped or entwined around any structural feature or routed through any ladders or catwalk equipment. Cables may be secured to existing anchors, supports, or brackets.

i.    Cables will not be installed with excessive slack producing a tripping, snagging, or entrapment hazard.

j.    All installed cables will be marked and identified. Adhesive or snap on jacket markers will be affixed to the cables on each side of any firewall, floor penetration, tunnel entrance point, and junction box connection. These identification tags will be attached securely and permanently to every cable or cable bundle and include the following information:

(1)    Installing agency or department

(2)    Termination points

k.    All personnel installing cables at TTU shall have completed a minimum of two hours of asbestos awareness training.

l.    Suspected asbestos-containing materials will be tested and verified as non-asbestos prior to disturbance.

m.    Only properly trained and licensed personnel will be allowed to disturb materials containing asbestos.

n.    All suspected asbestos-containing materials found to be damaged by personnel installing cables will be reported immediately to the Managing Director of Building Maintenance and Construction and to the Assistant Vice president for Research (Environmental Health and Safety).
