3.1.7 GUY TENSIONS:

3.1.7.1 Measure and record the tensions near the anchors of all structural and radial guys for guyed towers. Adjust guys as necessary to bring tension, alignment, and twist values within tolerances.

Tension values shall be within 5% of the design value. If the design value is not available tensions shall be brought to within 10% of the manufacturer’s rated braking strength of the strand as specified in TIA-222-H section 7.6. 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 COR. Guy tensions, before and after adjustment, shall be included in the tower inspection report in a tabular form. Provide a photograph of the digital reading on the Dillon Quick Check or similar digital device for each tension reading taken on each guy wire or TLE. 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.

3.1.7.3 All guy measurements shall include a date time stamped photo of the tension meter as well as stamped GPS coordinates.

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-H. 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.

3.1.9 TOWER TWIST:

3.1.9.1 Tower twist measurements shall be made by the "Leg Sighting" or "T-Square" method.

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.
