If equipment downtime is a concern for meeting completion of the pole installation process in accordance with 2545.3H “Pole Installation”, then provide at least two crews; one crew to stand the pole and the other crew to complete the anchor rod tightening procedure in accordance with the Contract Documents on the same day of standing the pole.

Erect structural steel members in a manner that will provide safety to workers, Inspectors, the public, and without damaging the steel members.

I.1 Traffic Signal Mast Arm Pole Structural Bolting

Use high strength bolts with a hardened washer placed either under the nut being turned during tightening for bolting mast arms and transformer bases to the poles.

Before structural bolt tightening of mast arms, luminaire extensions (plate to plate connections), and pole bases to the poles, ensure the slope of surfaces and bolted parts in contact with the bolt head and nut is no greater than 1:20 with respect to a plane normal to the bolt axis. Ensure the joint surfaces including bolt heads, nuts and washers are free of scale, dirt, loose scale, burrs, foreign material, and other defects that would prevent solid seating of parts.

Before assembling bolted connections, ensure bolt and nut threads, and the face of the nuts being turned into the washers are lubricated with an approved anti-seize lubricant listed on MnDOT’s Approved/Qualified Products List,

Place a calibrated torque wrench on the nuts to tighten the bolts to the required torque values shown on Table SS-2.3-1. Tighten bolts in steps of 20%, 60% and 100% of the required torque value respectively and use a cross tightening pattern for each step. Allow the bolts to relax for 10 minutes and retighten to 100

J Traffic Signal Mast Arm Pole Anchor Rod Tightening

Tighten traffic signal mast arm pole anchor rods in accordance with the MnDOT Anchor Rod Tightening Handbook “New Installation Procedures” and the MnDOT Anchor Rod Tightening Form.

Use the required low- profile hydraulic torque wrench on the top nuts to tighten anchor rods to the required torque values specified in the MnDOT Anchor Rod Tightening Handbook. Obtain Engineer’s approval of the wrench and provide proof of calibration performed within the last 12 months form an accredited calibration service before installing traffic signal mast arm poles.

Complete a MnDOT Anchor Rod Tightening Form for each traffic signal mast arm pole. Submit completed forms to the Engineer. Keep the form on the next page on a separate page so the contractor can remove it from the special provisions and use it in the field.
