Replace damaged poles or pole accessories with new. Before replacing, obtain the Engineer’s approval. Do not install poles or accessories from previous electrical systems. Immediately after standing the pole on the foundation complete the entire pole installation process. The pole installation process is from the time the pole is set on the foundation to the completion of final tightening of anchor rod connections in accorda nce with the Contract. Do not stop midway through the installation process. Do not stand poles on foundations without completion of final anchor rod connection tightening. If there are concerns of equipment downtime, then provide at least two crews;
one to stand poles and another crew to complete the required anchor rod tightening procedure in full on the same day of standing the pole. Ensure poles are set plumb on the foundations. Foundations not installed plumb will require re-installation if the pole cannot be set plumb on the foundation. H.1 Anchor Rod Connections Ensure the required anchor rods, nuts, washers, and pole base plate fit solidly together. Assemble threaded portions of anchor rods and nuts, and faying surfaces of nuts and washers to ensure threads and surfaces are free of the following:
Use anchor rods, nuts, and washers in accordance with the Contract. Use the amount of washers and nuts for each connection as specified in the Contract and pole manufacturer’s installation instructions. Do not remove required nuts or washers from the conne ction. Do not add extra washers, spacers, or other hardware to the connection other than what is required. Do not use lock washers. Place nuts, washers, and pole base plate on anchor rods in the installation order as specified in the Contract and manufacturer’s installation instructions. Ensure the top of the anchor rod extends at least one thread beyond the top surface of the top nut. An anchor rod end inside the top nut where no threads extend beyond the top surface of the nut and the top nut is not fully engaged on the anchor rod after tightening is not acceptable. Apply lubrication only to the exposed anchor rod threads above the base plate, top face of the top washers, and any surfaces on the top nuts that make contact with the anchor rod threads and the face of top washers as specified in Step 3 “Lubrication” of the New Installation Procedures, Anchor Rod Tightening Handbook. Do not apply lubricant before Step 3. Only apply an approved Electrolytic Corrosion Inhibitor lubricant listed on the APL, Lighting to the specified areas of anchor rod connections when installing stainless steel light poles. For coated steel and aluminum pole installation apply an approved lubricant Bridge grease/bridge bearing lubricant listed on the APL, Bridge or an approved Electrolytic Corrosion Inhibitor lubricant listed on the APL, Lighting to the specified areas of the anchor rod connections. Use wrenches designed for turning nuts to tighten anchor rod connections. Do not use pipe wrenches to turn nuts. Use wrenches sized specifically for the nut being turned. Do not use adjustable wrenches. Use calibrated torque wrenches to tighten anchor rods to the required torque values. Submit documentation of wrench calibration and certification to the Engineer in accordance with 2565.3A.13 “Calibration Requirements for Measurement Tools and Test Equipment” before installing poles. If the required torque values for tightening anchor rods cannot be achieved using a manual type torque wrench, then use a low profile hydraulic torque wrench listed on the APL, Lighting.
Use a working handheld digital pendant or, digital or analog gauge with the low -profile hydraulic torque wrench to ensure specified torque values have been met and can be verified in foot pounds by the installer and inspector during the tightening process. If the gauge display is in pounds per square inch (PSI), convert PSI to foot pounds and ensure the calculations are correct. Submit the PSI to foot pounds converted values to the Engineer before installing the poles. The submittal and Engineer’s review do not relieve responsibility for tightening anchor rods to the required torque values. The MnDOT Anchor Rod Tightening Handbook “New Installation Procedures” is required to use and follow along during the installation of poles Complete the required Anchor Rod Tightening Forms using one of the following; Screen- fillable PDF form – “fillable” on a computer (Adobe Acrobat Reader required) or blank screen- fillable PDF form downloaded and printed hard copies to fill out by hand (Adobe Acrobat Reader required). For aluminum poles, fill out the ANCHOR ROD TIGHTENING FORM- ALUMINUM POLES (Signal Pedestals and Light Poles). For stainless steel and coated steel poles, fill out the ANCHOR ROD TIGHTENING FORM - STAINLESS STEEL AND COATED STEEL POLES. Complete the required Anchor Rod Tightening Form at a rate of one form per every 15 light poles with a minimum of one completed form per Project and one form for every traffic signal pole per Project. Submit the completed forms to the Engineer.
H.1.a Single-Nut Anchor Rod Connections Aluminum poles requiring single-nut anchor rod connections are set directly on the foundation. Leveling nuts are not used in the connections. One heavy hex nut for each anchor rod is used to fasten the pole base to the foundation anchor rods.
