2.Assembly of Supports and Bolt Tightening -
a.Anchor Rods for Signal Supports and Fixed Base Luminaire Supports -
1.Installation - After foundation concrete strength and curing requirements are satisfied and after inspection of the foundation, pole installation may begin. Protect anchor rods, washers, and nuts from dirt and moisture. Lubricate anchor rod threads, nuts, and bearing surfaces that will turn during installation according to 02560.70. Estimate the required rake, if any, and set the lubricated leveling nuts accordingly, so that when pole installation is complete and all appurtenances are installed on the pole, the top of the pole is plumb with the base of the pole. Lift the pole into position on the leveling nuts and washers. Make sure all leveling nuts and washers are in full contact with the base plate. Install washers with lubricated bearing surfaces that turn during installation and lubricated top nuts, and bring to a snug tight condition. Snug tight is defined as the condition when all plies of the connection are in firm contact and can be obtained by the full effort of a worker on the end of a 12 inch long wrench. Several passes may be required to obtain uniform snug tightness. When all anchor rods are snug tight, proceed with installation of arms and other appurtenances, if not previously installed. When installation of arms and appurtenances is complete, and the pole is plumb as defined above, final anchor rod tightening may begin. If the pole is not plumb, adjust as required and repeat snug tightening as described above. Make sure all leveling nuts and washers are in full contact with the base plate. As a safety measure, provide crane support of the pole until anchor rods tightening is completed. Mark the initial relative position of each anchor rod and an outside ridge of each first nut above the base plate with a permanent felt tip pen or similar marker. Retain visibility of the marks for at least 7 Days to verify subsequent nut rotation. Rotate all first nuts above the base plate past snug tight an additional amount shown in 00962.46(j)(2)(e) in two passes. "Cheater" bars, multiplier wrenches, or slugging wrenches are allowed if required for large 00962.46 diameter anchor rods. After final tightening of the first nut above the base plate, tighten the second nut to a snug tight condition for assemblies with two nuts above the base plate.
2.Inspection - Notify the Engineer in writing at least 24 hours before starting installation. The Engineer will observe the installation and tightening operations to ensure that proper procedures are followed. The installation will be rejected if the geometry does not satisfy the requirements of 02560.05 or no permanent felt tip pen marks are present for at least 7 Days after installation showing the rotation past snug tight.
b.Anchor rods and High-Strength Bolts for Slip Base (Break-away) Luminaire Supports -
1.Installation - After foundation concrete strength and curing requirements are satisfied and after inspection of the foundation, pole installation may begin. Furnish, at no additional cost to the Agency, a calibrated torque wrench of a capacity appropriate to the size and type of the bolts being tightened. Confirm the accuracy of the calibrated torque wrench through calibration by an approved independent testing agency at least once a year. Protect anchor rods, washers and nuts from dirt and moisture. Lubricate anchor rods, nuts and bearing surfaces that will turn during installation according to 02560.70. Estimate the required rake, if any, and set the lubricated leveling nuts accordingly, so that when pole installation is complete and all appurtenances are installed on the pole, the top of the pole is plumb with the base of the pole. Install the anchor plate on the leveling nuts and washers. Make sure all leveling nuts and washers are in full contact with base plate. Install washers with lubricated bearing surfaces that turn during installation and lubricated top nuts, and bring to a snug tight condition. Snug tight is defined as the condition when all plies of the connection are in firm contact, and can be obtained by the full effort of a worker on the end of a 12 inch long wrench. Several passes may be required to obtain uniform snug tightness. When all anchor rods are snug tight, proceed with the "Slip Base Bolting Procedure" as shown and lubricate bolt threads and bearing surfaces that turn during installation according to 02560.70. When the slip base bolting procedure is complete, final anchor rod tightening may begin. As a safety measure, provide crane support of the pole until anchor rod tightening is complete. Mark the initial relative position of each anchor rod and an outside ridge of each first nut above the base plate with a felt tip pen or similar marker. Retain visibility of the marks for at least 7 Days to verify subsequent nut rotation. Rotate all first nuts above the base plate past snug tight an additional amount shown in 00962.46(j)(2)(e) in two passes. "Cheater" bars, multiplier wrenches, or slugging wrenches are allowed if required for large diameter anchor rods.
2.Inspection - Notify the Engineer in writing at least 24 hours before starting installation. The Engineer will observe the installation and tightening operations to ensure that proper procedures are followed. 00962.46 The installation will be rejected if the geometry does not satisfy the requirements of 02560.05 or no permanent felt tip pen marks are present for at least 7 Days after installation showing the rotation past snug tight.
c.High-Strength Thru Bolts in Mast Arm-to-Pole Connections and Luminaire Arm-to- Pole Connections -
1.Installation - Do not reuse galvanized high strength bolts. Retightening previously tightened bolts that may have been loosened by the tightening of adjacent bolts will not be considered a reuse. Provide all high strength bolts according to the details shown. Use bolt, nut, and washer combinations from the same rotational capacity lot with new and unused direct tension indicators with protrusions in contact with the hardened washer. Protect fasteners from dirt and moisture. Do not remove the lubricant that is present in as delivered condition. Lubricate threads, nuts, and bearing surfaces that turn during installation according to 02560.70. Bring the connection to a snug-tight condition. Snug-tight is defined as the condition when all plies of the connection are in firm contact and can be attained by applying the full effort of a worker on the end of a 12 inch long wrench to each bolt in the connection. Tighten all fasteners in the connection by progressing systematically from the most rigid part of the connection to the free edges in a manner that will minimize relaxation of previously tightened fasteners. In some cases, proper tensioning of the bolts may require more than a single cycle of systematic partial tightening. After attaining a snug-tight condition, tighten all fasteners in the connection by progressing systematically from the most rigid part of the connection to the free edges until the direct tension indicator spaces between the protrusions refuse entry of a 0.005 inch feeler gauge in all spaces except one. "Cheater" bars, multiplier wrenches, or impact wrenches are allowed. Provide impact wrenches with enough capacity and supplied air to tighten each bolt in 10 seconds or less. Do not use a slugging wrench or similar method for final tightening.
2.Inspection - Notify the Engineer in writing at least 24 hours before starting installation. The Engineer will observe the installation and tightening of bolts to determine that the tightening procedures are properly used. Inspect all bolts in each joint. The joint will be accepted as properly tightened when one open space allows entry of a 0.005 inch feeler gauge. If there is more than one space between the direct tension indicator protrusions that allow entry of a 0.005 inch feeler gauge, re-inspect all bolts, retighten bolts in the joint as required, and resubmit the joint for inspection. If no spaces exist between the direct tension indicator protrusions that allow entry of a 0.005 inch feeler gauge, replace bolt assembly, tighten bolts in the joint as required, and resubmit the joint for inspection. Connections that have all bolts fully tightened can replace one bolt at a time without providing crane support of the mast arm. The installation will be rejected if the geometry does not satisfy the requirements of 02560.05.
d.High-Strength Bolts in Tapped Holes in Mast Arm-to-Pole Connections and Luminaire Arm-to-Pole Connections -
1.Installation - Protect fasteners from dirt and moisture. Lubricate bolt threads and bearing surfaces that turn during installation according to 02560.70. Provide all high- strength bolts with hardened flat washers under the element turned during tightening. 00962.50 If arms or appurtenances are attached after pole erection, support them until bolts are snug tight. Install high-strength tapped hole connections to a snug tight condition. Snug tight is defined as the condition when all plies of the connection are in firm contact, and can be obtained by the full effort of a worker on the end of a 12 inch long wrench. Mark the initial relative position of the outside ridge of each turned element (nut or bolt head) and plate with a permanent felt tip pen or similar marker. Retain visibility of the marks for at least 7 Days to verify subsequent nut rotation. Rotate the top nut of each bolt past snug tight by the amount in 00962.46(j)(2)(e). Several passes may be required to obtain uniform snug tightness. "Cheater" bars, multiplier wrenches, and impact wrenches are allowed. Provide impact wrenches with enough capacity and supplied air to tighten each bolt in 10 seconds or less. Do not use a slugging wrench or similar method for final tightening.
2.Inspection - Notify the Engineer in writing at least 24 hours before starting installation. The Engineer will observe the installation and tightening operations to ensure that proper procedures are followed. The installation will be rejected if the geometry does not satisfy the requirements of 02560.05 or no permanent felt tip pen marks are present showing the rotation past snug tight.
e.Final Tightening - Required final tightening of anchor rods and high-strength bolts are shown in the following Table: Connection Type Rotation Past Snug Tight ASTM F1554, Grade 36 Anchor Rods 30° (1/12 turn) ASTM A449 Anchor Rods 60° (1/6 turn) ASTM F1554 Grade 55 Anchor Rods 60° (1/6 turn) ASTM F3125, Grade A325 Bolts 60° (1/6 turn)
3.Bolt Inspection - The Engineer will observe the installation and tightening operations to ensure that proper procedures are followed. All inspections will be visual and no testing will be conducted. The installation will be rejected if the geometry does not satisfy the requirements of 02560.05.
k.Plate Flatness - Faying surfaces of plates shall be flat to within a tolerance of 1/32 inch in 12 inches and a tolerance of 1/16 inch overall. Base plates with leveling nuts shall be flat to within a tolerance of 1/8 inch in 12 inches and a tolerance of 3/16 inch overall.
00962.48 Coating - Prepare and powder coat supports according to the applicable portions of
Section 00593 or prepare and coat supports according to the applicable portions of Section 00594. Provide coating materials for field application, repairing damaged coatings, and coating hardware after installation, according to Section 00593 or 00594. Do not coat: • Slip plate or arm connection surfaces. • Slip base bolting hardware. • Anchor rods, anchor rod washers, and anchor rod nuts.
00962.50 Grounding and Bonding - For fixed base poles, provide a 1/2 inch, Type 308, 309, or 310
stainless steel stud on the inside of the shaft. Locate the stud directly opposite and level with the 00962.50 handhole in the pole. Attach grounding electrode conductors and bonding conductors to the stud with a grounding wire clamp, "acorn style". For slip base poles, do not allow the grounding wire to intrude into the slip plane. Instead, run a bond wire from the grounding electrode to a 1/2 inch, Type 308, 309, or 310 threaded stainless steel stud welded to the bottom base slip plate. 00963.30
