This shall include mounted sheaves, guides, rollers, outriggers, associated block assemblies, and bearings (sheave bearings and swing bearings) where installed. Check weep holes for excessive running rust.

3.1.1.3 All connections, splices, welds, bolts, nuts, and rivets shall be checked for deficiencies, defects, and looseness. Check a minimum of 15% of all structural bolts in various locations around the tower for looseness by tapping with hammer. Looseness shall not be checked by torquing with a wrench. If a bolt is loose make note on the report, explaining exact location.

Hand-tighten the bolt, measure its diameter and length for future replacement and note in report.

Spray paint the bolt with a black enamel paint to mark it for quick visual identification.

3.1.1.4 Inspect tower foundation for settlement, corrosion, cracking, or damage. Check condition of grout and anchor bolts.

All tower guys and antenna arrays shall be inspected from the ground and from the towers, using high-powered binoculars. Special emphasis shall be given to all insulators, connections, and strand material. This work shall be completed during periods of clear skies so that the appropriate lighting is available for the visual observations. If visual inspection shows a need for further investigation by riding a guy wire, notify the Contracting Officer. Riding of guys will require a contract modification. Any damage or deterioration to guys shall be photographed and mapped on a sketch to indicate location and extent of damage.

Tension values shall be within 5% of the values listed in tower erection and maintenance manuals for each individual tower. If attempts to bring tensions into allowable limits are unsuccessful, document and provide final tensions. Do not disconnect any guys without prior approval from the Contracting Officer. Guy tensions, before and after adjustment, shall be included in the tower inspection report in a tabular form. Do not adjust the guy tensions until the major maintenance on the tower has been completed.

3.1.7.2 All of the measurements and any guy tension adjustments shall be made with the wind from a constant direction (+/- 20 degrees), at a speed of less than 15 knots. Weather conditions including temperature, wind direction, and speed shall be recorded.

3.1.8 TOWER ALIGNMENT:

3.1.8.1 Measure and adjust as necessary the vertical alignment of the tower structures for tolerances as outlined in TIA-222-G. Tower vertical alignment shall be checked using the "One Leg" (triangulation) method. Alignment values plotted shall be the average of two (2) readings, one with the scope direct and the other with the scope inverted and then reversed. Plot sheets shall show the location of the tower center at each guy level and shall be submitted with the tower report, including the alignment values. Raw data and a description of the methods used shall be included in the Contractor's report.

Twist values shall be measured in degrees clockwise or counter clockwise using the base platform as the zero reference. Twist markers shall be set at 1/2 degree (7'- 5") intervals 850 feet from the tower base. The Contractor will not be expected to adjust the tower twist, however, the Contractor shall ensure that the re-guying operations do not adversely impact the existing twist;

therefore the twist shall be measured and recorded.

3.2 MINOR MAINTENANCE:

The Contractor shall provide all materials, equipment, and labor, to perform the maintenance items specified herein.

3.2.1 MINOR CORROSION REPAIR: All areas on all towers that have minor corrosion shall be mechanically cleaned to bear metal and coated with a cold galvanizing compound.

3.2.2 SAFETY PRECAUTIONS: Contractor shall take necessary precautions with appropriate respiratory devices when disturbing paint on the tower. Although none of the towers are known to have high levels of lead based paint, the Contractor shall assume all towers have been painted with led based paint. The Contractor shall comply with Federal, State, and Local regulations for disturbing, handling and disposal of lead based paint.

3.2.3 TOWER IDENTIFICATION NUMBER: All towers should have an identification number tag installed on the lowest 5 vertical feet of the tower structure or foundation. An example identification number tag is included as Figure (1) below. If it is predetermined that a tower does not have an identification number tag installed, a new tag may be provided by the Contracting

Officer Representative to the Contractor for installation. This tag shall be installed at the North West corner of the foundation using concrete fasteners and epoxy adhesive. If no tag is provided, the Contractor shall use a weatherproof permanent marker to label the tower with the appropriate identification number, as per Appendix A.
