(c) Number and type of cables being installed;
(d) Termination locations;
(e) Identification system to be used on the cable;
(f) Installation technique/method to be used, including a clear description of the method used in sealing firewall and/or floor penetrations;
(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.

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.
